Alternatives to drive SA’s energy mix for optimum development

The raging debate over the suitability of nuclear energy is typical of South Africa’s flawed approach to energy policy. We are driven by desperation to consider alternatives rather than being proactive and acting strategically to optimise outcomes.

The Eskom debacle has forced the government to consider other options such as gas in addition to nuclear – just like the sale of state assets is driven by the need to bail out Eskom rather than economic policy. Invariably, we ask the wrong questions and then proceed to provide the most precise answers to them.

The strategic energy policy question is not whether nuclear energy is better than renewable energy or vice versa. The question is: what is the optimal energy mix for South Africa that will best address our economic development challenges? Any optimisation problem relies on the formulation of the objective function and the constraints imposed on it. While some are fuzzy on the objective function, they seem clear that we can either have nuclear, wind or solar, and nothing else.

My argument is that there are other alternatives to be considered in the energy mix. Firstly, the strategic envelope for the analysis of our energy policy should be the Southern African Development Community (SADC), not the Republic of South Africa, given that there are significant energy sources outside South Africa, with South Africa being a massive energy sink. The DRC has hydro energy resources, Botswana has coal resources, Mozambique and, to a lesser extent, Namibia have significant natural gas resources. It is also unclear why our own coal resources are not in the future energy mix, given our relative size to massive coal burners such as China and India.

Back to the objective function: what do we want to achieve through our energy policy? The goals of an energy policy should include competitively priced energy, energy security, supply stability, minimal environmental impact, employment creation, and positive transformative impact on the overall economy. One could use the current energy mix as a base case to compare alternative mix options, including all the energy sources mentioned above.

We have not even considered importing Liquefied Natural Gas (LNG) as an alternative or local hydraulic fracking. We could divert all our thermal energy demand to LNG and simultaneously use LNG to provide feedstock to the PetroSA GTL plant. That would reduce our electricity demand and also make sure we sweat an existing investment at the Mossgas plant.

At face value, it seems a nuclear plant investment will have less positive transformative effect on the overall economy.

We need a breath of fresh air in this energy policy debate. This is too important an issue for South Africa’s future to be driven by sector specific interests.

In the debate over water scarcity, it’s time to think solar

With more than 780 million people lacking access to potable water and 1.3 billion people lacking access to electricity, sustainable water and energy production is critical to our planet’s future. It is in this context that leaders from around the world are gathering at the World Future Energy Summit in Abu Dhabi, to address the water-energy nexus and its effect, elevating this important discussion to the global agenda.

According to the International Energy Agency, energy production accounts for 15 per cent of the world’s total water withdrawal – defined as water withdrawn from a groundwater source – which amounts to an estimated 580 billion cubic metres of fresh water per year. Thermoelectric power plants already account for over a third of fresh water withdrawal in the United States, where the volume is even more than the water used for agriculture, and in Europe.

There is no doubt that the water-energy nexus is real and of particular concern to water-scarce regions, such as the Middle East. The fact of the matter is that most energy generation technologies — including coal, nuclear and even concentrating solar power – consume tremendous amounts of water during operations, for processes such as fuel extraction, cooling and cleaning.

As our energy needs continue to grow, so will our use of water to generate it. The World Bank predicts that while global energy consumption will increase by 35 per cent by 2035, water consumption will increase by 85 per cent during the same period.

Looking at it in the context of energy demand in the Middle East, which has some of the highest per capita water and energy consumption rates in the world, the management of water resources will be critical to driving growth in the country’s generation capacity.

Water is a finite resource and its use in electricity production should be managed through diversified power generation that minimises water usage.

Sunlight, on the other hand, is an abundant resource and can help mitigate some of the effect on our water resources. Photovoltaic (PV) solar energy is one of only two electricity generation technologies with comparatively negligible water consumption.

PV energy systems provide a sustainable solution to the water-energy nexus by generating clean electricity with little to no water use. Most of the water consumed at solar plants is used to ensure that workers on-site stay hydrated.

On a life cycle basis, PV also consumes less water than most other power generation sources, including hydrocarbon-based technologies and biofuels, in the production process.

With the smallest carbon footprint, lowest life cycle water use, and fastest energy payback time in the industry, thin-film PV modules provide a sustainable solution to water scarcity and energy security.

While a power portfolio that completely excludes thermal generation is an unrealistic expectation at this time, the reality is that water conservation needs to remain a priority. As world leaders and decision makers meet in Abu Dhabi this week, it will also be important for them to attempt to respond to the issue in terms that will deliver tangible results.

Mapping and Influencing Global Perceptions of Waste to Energy

Although more than 800 Waste to Energy (WtE) plants operate in over 40 countries worldwide, this still only represents about 10% of global municipal solid waste processing, meaning now is the perfect time to make the most of the opportunities to expand the global use of WtE.

This is not just because of available capacity, but more because of the current combination of three factors: The move away from landfill; the need for more renewable energy; and the need for greater energy security.

On the global map these attitudes to WtE, illustrated simply by a traffic light system of red, yellow or green to highlight the level of positive or negative perceptions, show that many prospects exist, especially in the U.S. where over half of all states still rely on landfill alone.

However, given the right communications and messaging, there are real opportunities in WtE and us making the most of this hugely beneficial technology. Key to this communication is learning from previous experiences when it comes to conveying the advantages of waste to energy technology and knowing where, and why, others have failed.

Quite simply, without knowing the historical context of waste to energy, it’s likely the mistakes of others will continue to be repeated very quickly.

Attitude Problem

WtE that conforms with the European Waste Incineration Directive (WID) emissions standards is clean and provides a win-win with the disposal of waste and the generation of energy. If plants effectively use the waste heat generated in an efficient Combined Heat and Power (CHP) system, then the environmental advantages are even more significant.

So what’s the problem and why aren’t countries rushing to adopt WtE? In a nutshell, globalisation over the last 10 years has transformed international trade and, to be more accurate, international finance, into a very small market indeed, with a handful of major corporations enjoying world dominance.

This, coupled with the rise of the Internet and more recently, global social media, has resulted in information from one part of the world being quickly transported to another. We live in a truly ‘Global Village’ and, whilst this brings many advantages, one disadvantage is that the misunderstandings and outdated views about WtE – many of which come from the time of poor performing incineration plants from the 1970s – continue to circulate.

As a result, countries new to WtE may find a surprising amount of opposition from communities near to proposed plants, even when they have no experience of the technology previously. Interestingly, in some countries where pre-WID technology was used some years ago with no issues at the time, opposition is now growing to new plants that are far cleaner and much more efficient than their predecessors.

Opposition groups around the world learn from each other very quickly, and although some organisations are good at forming new arguments to focus their opposition in new directions, most community-based groups tend to use material that is being circulated by other groups. This distribution of outdated information leads to the assimilation of arguments which match a person’s negative perceptions rather than allowing for the genuine reviews of all literature available.

This mindset means that excellent websites, such as that of CEWEP – which present all the counter-arguments in increasingly engaging ways – are being ignored with the key audience e.g. those who live near proposed plants, not considering their information as objective and dismissing it, while collecting anti-information.

What Not To Do: Hong Kong

Although Europe has been the main focus for WtE development and growth over the last 20 years, the next 20 years is likely to see global growth will move to Asia. With a classic mistake of failing to learn from the past, many Asian governments, like Hong Kong, which is trying to develop alternatives to landfill, are running into the same old arguments about WtE.

Hong Kong has huge cash reserves and, as such, can afford any technology to address its significant waste problem. It has limited land availability, with landfill sites reaching capacity and neighbours objecting to extensions, coupled with a rapidly growing population significantly increasing waste volumes.

With increasing interest in environmental issues among Hong Kong residents, and a need for more renewable energy, WtE would seem an obvious solution. However, the government’s early attempts to suggest this have resulted in significant opposition and the moving of a large proposed plant (900,000 tonnes pa) away from the centres of population bringing with it a dramatic increase in costs.

Most of the opposition in Hong Kong has focused on the impact of emissions, and the legitimate argument that, although the electricity at the high-cost island development could be utilised, the heat cannot.

The result has been significant protests against the plant and delays in both the funding allocation. In the meanwhile, the volume of waste is ever increasing and landfills are getting closer to capacity and closure.

Early attempts by Hong Kong’s government to introduce waste to energy resulted in a 900,000 tpa plant attracting significant opposition and being relocated away from populous areas

Hong Kong‘s main mistake made was the failure to deliver the immaculate three-stage communications model to generate public acceptance for change:

  • Step 1: There is a problem
  • Step 2: Generate a desire for a solution
  • Step 3: Propose the solution

This model ensures that the population not only becomes aware there is a problem waiting to be solved, but that they understand the context for that change and, with encouragement, are happy to be involved in the delivery of the solution. This buy in is essential to an effective integrated waste management plan that is likely to involve substantial changes in behaviour.

Hong Kong isn’t alone, the Philippines, India, Malaysia, Thailand and Bangladesh have all run into similar problems with significant public opposition, mostly centring on perceived health hazards due to toxic emissions. Even in China, there is increasing public protests to WtE. Between 2007 and 2012, there were at least a dozen protests by local residents. This year in Hangzhou, more than 10,000 tea farmers took direct action against a proposed plant in the Zhongtai suburb, upwind of the tea plantations.

The protest achieved its objective. Shanghai Daily reported that work on the construction has stopped. City officials said: “We will invite the local people to participate, fully listen to and seek every one’s opinions…” Clearly, public consultation before the decision to construct the plant could have been more helpful.

Positive Prospects

Every country has a different cultural and historical context for WtE and the UK is no exception. in the past, even though plants have existed since Victorian times when horse-drawn carts brought wastes ‘Destructors’, WtE plants were not actually needed.

However, countries like Denmark, Sweden and, to a degree, Germany have always had the need to maximise resources due to a lack of cheap landfill and the serious need for heat and energy, particularly in the winter. This was especially so in Denmark where a lack of fossil fuels meant that WtE constituted a necessity rather than a simply one option.

Two Asian countries with positive reception are Japan and Singapore. Recycling is taken very seriously in Japan, yet it still burns more waste in cities than any other developed country.

Tokyo has 21 WtE plants, all sited within the city and many with facilities for the community to use, such as leisure centres with swimming pools heated by the plants themselves. This community benefit and substantial community education programme has helped generate a more objective response from communities near to sites earmarked for new plants.

In Singapore, they took the decision to focus on WtE back in the 1970s as a solution to the country’s growing population, limited land space and the fact that energy recovery was needed due to a lack of natural resources. To manage increasing waste production, the City state published its Green Plan in 2012, with a significant shift to material recovery through recycling while looking to build new WtE. There is some limited opposition from groups such as Toxics Watch, but the majority of people are happy to accept the new plants.

So, how did Singapore and Japan get it right? There are undoubtedly some parallels with the positive situation in Denmark – the two problems of the need for energy and lack of landfill – but also the constructive ongoing public dialogue which has led to a good understanding of the two issues and therefore, the need for change.

Also crucial to their success is the fact that all three countries consider providing some form of community benefit as fundamental to their projects. Most WtE plants in Denmark are connected to district heating so near-neighbours get cheaper heating and hot water.

The Toshima Incineration Park in Japan has 180,000 visitors per year with most using the leisure facilities. In simple terms, these countries satisfy one of the fundamental principles of human behaviour when it comes to considering whether to protest – what’s in it for me?

Understanding Objection

It can be argued that there are three core principles about human motivational behaviour when it comes to development and change:

  1. The perceived impacts of the development, especially financial impacts
  2. What’s in it for me
  3. People don’t like change.

So, if the starting point for those people nearest to a proposed WtE plant is perceived emissions impacts, fear of a reduction in the value of their home and seeing nothing of any value in the development for them, then it’s hardly surprising that most people are opposed.

The fact that people don’t like change is almost irrelevant, but not quite. The point about this principal of reactionary behaviour is that it’s almost an instinctive human reaction to believe they don’t like change. People don’t mind change if principals one and two are positive for the individual, or perhaps more importantly, they have control over the change.

People change things all the time – they grow up, get an education, move/improve their homes and live in communities that change all the time. However, in most of these situations, changes are slow and/or people perceive some form of control over them i.e. it’s their choice (often when it’s not). Where the change is rapid and where they believe they have limited or no control, the reaction is generally negative.

This has implications for those people who are communicating messages about change. Far too often it’s the developer who drives any consultation process, often with local government looking on nervously. Our experience in the UK shows that the best combination for the successful delivery of WtE is where the developer and local government are committed to the proposed development with aligned interests.

Three Steps To Deliver

There are three essential steps to deliver this new paradigm, where WtE is seen as a positive development that communities will not only accept but, on occasion, may proactively seek to take place on their own doorstep.

Step 1: National Positioning
This provides the ground work to explain that there is a problem and something needs to be done about it. It takes the focus away from a proposed location and onto the problems. In the case of Hong Kong, this should have been a campaign that outlined the scale of the evolving problem of increasing population, the increase in waste, lack of landfill and the necessity for a more environmental solution.

This debate, supported by independent third parties, could have been held publically through the media before leading into the development of a strategic plan which included reference to feedback from public consultation.

Specifically in the case of Hong Kong, they could have specified that the need for change was urgent, and highlighted the crucial issue of all landfill sites closing within five years.

Step 2: A need for a solution
With greater awareness of the issues and the appreciation of urgency which can be achieved by step 1, it would be possible for any government to argue the need for a truly integrated waste management solution – explaining how wastes would be moved up the waste hierarchy with an enhanced recovery and recycling process.

This is an important step as it demonstrates that any residual waste solution will be considered from this context i.e. not simply sending all landfill to WtE without attempting to recover materials first. It also demonstrates of the need for public participation.

All the available and developing technologies would need to be discussed, along with likely time frames for delivery and relative costs. Research in the UK has shown that when all the facts are presented to communities about the issues, solutions and relative costs, they tend to review the issues in a far more objective light and therefore have the potential to accept change far more readily than before.

As part of this process, all renewable energy could be repositioned as desirable, but WtE also has the benefit of disposing of residual waste – it’s a genuine win-win solution.

Step 3 – Local delivery of WtE
After step 2, there should be regional debate about delivery before any planning applications or sites are mentioned. This will generate greater awareness of the issues and potential solutions before personal vested interest, and the three principals of personal behaviour can begin. This will result in an informed debate at a local level. It will be inevitable that some people who end up close to proposed facilities will still react in the same way as before, but they will now be doing so against the more widely understood and accepted need for the facilities from the wider community.

Conclusion

WtE should be one of the number one technologies for the 21st century, particularly in those parts of the world where population is growing fast and there is a real need for alternative energy sources – which is virtually everywhere.

To make the most of the huge potential global demand for this energy source, we must learn from past mistakes. By acknowledging the wealth of internet myths and outdated information still readily available surrounding WtE, and providing compelling information we can address these obsolete arguments and communicate effectively with communities.

Paul Davison is managing director of Proteus Environmental Communications

  1. New Zealand generates about 2.5m tonnes per annum (tpa) of MSW with around 25% going to WtE. Regulations would make further plants costly and time consuming to achieve.
  2. Each Australian state has its own WtE policy. About six plants exist with cogeneration and supporting manufacturers. Opposition includes the National Toxics Network of Australia. The Alliance for Clean Environment produced a report in 2008 suggesting a link with cancer.
  3. Singapore is densely populated with limited resources and so has always been pro WtE. In 2012, 2.45m tonnes of waste went through the existing four WtE plants with recycling at approximately 60%. New plants are being proposed to update the technology.
  4. Landfill dominates waste disposal in Thailand and Malaysia, but MSW is on the rise. There are three small WtE plants and around 96 landfills. Opposition in both countries has been strong.
  5. Urban India generates approximately 70m tpa of MSW which increases by 50% per decade. Much is handled by informal recyclers, but about 80% goes to landfill and, often, to dump sites. About six WtE plants are under construction or being commissioned with limited public opposition from informal recyclers who fear losing income.
  6. China overtook the U.S. as the world largest waste producer in 2012 and sees WtE as a significant opportunity. Three state owned energy companies have been established to manage the introduction of the technology. However green NGOs are increasing and groups, such as Green Beagles, report several public opposition protests to WtE.
  7. Hong Kong has a population in excess of eight million and is growing rapidly with limited land availability and four old landfills. A larger 900,000 tpa WtE being built on an island faces significant opposition arguing a lack of recycling, atmospheric pollution and impact on human health, as well as cost and alternative technologies.
  8. Densely-populated Japan has always had a need for more energy and, in a similar way to Scandinavia, was an early WtE technology adopter with good levels of public understanding. Home waste sorting is a national hobby, with some authorities succeeding with over 30 different bins. South Korea also has a positive attitude towards WtE.
  9. Landfill is still favoured in Russia, although a lot of wastes go to illegal dumps. Moscow and St Petersburg have looked at WtE and there are about 10 existing plants. New plants receive considerable opposition over pollution, human health, cost and the lack of significant recycling.
  10. Scandinavia, Germany, Austria, France and the Benelux all have significant numbers of WtE plants with little opposition and, in Denmark and Sweden, considerable support due to district heating. Recently there has been some opposition in France – mainly focused on dioxin emissions. Over capacity in Germany and Netherlands has resulted in significant imports of RDF from the UK.
  11. The UK and Ireland have the potential for more plants, but significant opposition has occurred and will continue for any proposed new plants, particularly for commercial plants not tied to a Local Authority.
  12. Waste disposal has featured heavily on Italy’s media agenda over the last 15 years. WtE’s biggest opposition relates to in Tuscany, specifically the Lucca provincial WtE. The plant, built despite massive opposition, failed dioxin limits in 2003 and was closed, reopening in 2007 before failing again in 2008. and again in 2009. It was ‘seized’ by officials in 2010 another failure and the plant’s manager sent to trial. Italy is focused on Zero waste and new WtE plants face opposition.
  13. The U.S. has significant numbers of WtE plants but most are quite old and will need updating in coming years. Obama’s recent focus on GHGs from energy generation provides a significant opportunity, but opposition focused on emissions, specifically dioxins, will be high
  14. Urban Brazil generates around 250,000 tonnes of MSW per day (2008) with 98% being landfilled and about 0.03% incinerated with no energy recovery. WtE is as a significant opportunity, although it will face difficulties with low landfill gate fees. Awareness of WtE is limited, however, energy is expensive.
  15. The Argentinian government brought in a zero-waste law in 2005, banning incineration. However, increasing volumes of waste in Buenos Aires and strict landfill avoidance regulations are forcing the city to look again and consider AD and mass burn WtE. Plants will face massive opposition with most of the arguments simply focusing on the fact it’s against the law!
  16. Most of Africa can’t finance WtE, lacks the supporting infrastructure or is prejudiced against it Also, MSW is roughly 70% ‘wet’ organics making some WtE technologies a challenge. In South Africa clinical waste incineration is the norm, but emissions checks are limited. A new law was adopted in 2009, but again, the country lacks the infrastructure to effectively monitor emissions. A new WtE in Tanzania was built with foreign assistance. If successful, it could encourage further trials.

‘Significant progress’ for SA’s nuclear programme

The South African government has been holding vendor workshops with countries it could potentially partner with for its nuclear build programme, the Presidency said in a statement on Wednesday. This marks “significant progress” for the government in its engagements with various prospective nuclear vendor countries as part of the process towards the implementation of the expansion in the nuclear new build programme, the statement said. Intergovernmental framework agreements have been signed with Russia, France, China, South Korea and the US, marking the “initiation of the preparatory stage for the procurement process”, the Presidency said. Delegations from these countries have presented technology they believe would best suit local conditions at these workshops, held during October and November. The vendor workshops form part of the government’s technical investigation “in preparation for a procurement decision”, the Presidency said.

Future energy mix

Potential vendors have had to show how they would best meet the 9 600MW (9,6 GW) threshold that the South African government has set for the country’s future energy mix.The countries all have pressurized water reactor nuclear technology, which is similar to that used at the Koeberg nuclear power plant in the Western Cape.”South Africa has been safely using this technology for the past 30 years,” Mac Maharaj, the President’s spokesperson, said. Senior technical government officials, representatives from state-owned entities in the energy field, as well as academics involved in nuclear and engineering programmes attended the workshops, leading to “robust and open discussions” with vendors, Maharaj said. Guidelines for the expansion of nuclear power to ensure energy security based on a sustainable energy mix have been set out in the National Development Plan, the Nuclear Energy Policy, the Nuclear Energy Act and the Integrated Resource Plan (IRP) adopted in 2011. Under the NDP, the government is required to do a thorough technical investigation before making a procurement decision.The Presidency said its commitment to nuclear energy would be accompanied by the commitment to a “procurement process that is in line with the country’s legislation and policies”. “The nuclear new build programme will create a massive infrastructure development, thus stimulating the economy and enabling the country to create thousands of high- quality jobs for engineers, scientists, artisans, technicians and various other professions, develop skills and create sustainable industries, and catapult the country into a knowledge economy,” said Maharaj.

21st Century Coal – Report: International Energy Agency

Green Business Journal 9 (2013)

Coal: currently supplying more than 40 percent of the world electricity consumption, providing an essential 70 percent input of world steel production, and representing approximately 30 percent of the global primary energy supply. Why is coal such a widely utilised resource today? It is cheap, abundant, easily accessible, widely distributed across the globe, and easy energy to transport, store and use. For these reasons, coal is predicted to be used extensively in the future. But, being a non-renewable resource, its production and use inevitably results in various issues across the value chain.

The primary mandate of the International Energy Agency (IEA) is to promote energy security amongst its member countries through collective response to physical disruptions in oil supply, and to provide authoritative research and analysis on ways to ensure reliable, affordable and clean energy for its 28 member countries and beyond.

In doing so, a report was researched and created by IEA which focuses on the technology path to near-zero emissions (NZE). The phrase “21st Century Coal” was adopted by the US and China to describe the importance of strategic international partnerships to advance the development of NZE technology and the report demonstrates the reasons for confidence in coal’s ability to provide a solution to the global objectives of economic sustainability, energy security, and NZE, and is broken up into four areas of consideration.

1. Coal and the CO2 challenge

Discussed here are the benefits of and the need for coal, issues associated with coal use especially related to carbon dioxide (CO2) emissions, as well as roadmaps to improve coal use and continue on a path toward zero emissions. With the increase in the global demand for energy comes the increase in the release of CO2 emissions. The IEA has found that with attempting to mitigate greenhouse gas (GHG) emissions, the costs of achieving climate goals are significantly reduced when carbon-capture and storage (CCS) technologies are implemented. This, along with increasing the thermal efficiency, can effectively lower carbon emissions from fossil-fueled power plants. The development and deployment of advanced coal with CCS technologies that is needed to achieve substantial carbon emission reductions will require extensive research, development, and demonstration investment.

2. Evaluation of advanced coal-fuelled electricity generation technologies

The IEA report provides insights into groundbreaking technology innovations for advanced coal plants to improve efficiency and reduce emissions including CO2. The report finds that there are multiple types of coal-fueled power plant technologies that exist or are being developed, but considerable advancement still needs to take place in this regard. More advanced, future technologies are definitely capable of further improving efficiency. In particular, fuel cells hold the potential of achieving increases in efficiency of up to 60 percent.

3. Carbon capture, utilisation and storage (CCUS)

Focus is drawn to the potential for enhanced oil recovery (EOR) to enable the economic viability of CCS, together with the need for and status of CCUS demonstrations. CCS demonstrations are needed most often on power plants as these plants play major roles in releasing carbon emissions. But, significant government support is needed for these demonstrations to be carried out. The utilisation of enhanced oil recovery (EOR) seems to be the way forward as additional streams of revenue assists the feasibility and capability of the projects. The IEA has found that methods to increase carbon storage in conjunction with EOR may further increase the capacity to store.

4. Flexibility of coal-fuelled power plants for dynamic operation and grid stability

The essential features of fossil fuelled power plants are assessed on their ability to operate dynamically on grids with intermittent wind and solar. Improving the flexibility of existing and developing coal plants can be accomplished through various strategies which involve both technical and operational improvements. These include implementing coal plant flexibility as early in the design process as possible, when it is most effective; optimising use of the capabilities of existing control systems; and collecting and using lessons learned to establish better operating practices.

Conclusions

It is technically possible today to incorporate equipment to capture CO2 in all types of new coal fuelled power plants. Depending on available space and other considerations, such equipment also can be retrofitted to existing coal fuelled plants. The importance of retrofit should not be underestimated based on the large number of new coal units being added.

Unfortunately, today’s CO2 capture technology is very costly. A recent review by the IEA of a variety of engineering studies conducted by a range of organisations that showed the cost of electricity from a new coal power plant with CO2 capture was estimated to be from 40 to 89 percent higher than a new coal plant without CO2 capture.

Ultimately, in order to get over the hurdle and achieve the cost reductions brought by technology maturity, it will be necessary for governments to specifically support CCS demonstration projects with capital grants as well as support for the power prices. Even if additional revenues can be obtained from the sale of CO2 for EOR, they may not be sufficient to allow full financing in all cases.

While coal use remains significant, its continued use has been challenged by growing environmental concerns, particularly related to increases in anthropogenic CO2 emissions. Adding technologies that can reduce CO2 emissions from coal (primarily by using CCS or CCUS) is possible but adds considerable cost, risk, and complexity to coal fuelled power plants, particularly at their current stages of maturity.

Coal remains an important and prevalent fuel for the production of electricity. Its low cost, abundance, and broad distribution make it attractive for power production, particularly in emerging countries such as China and India, where coal fuelled power has increased dramatically in recent years as demand for energy and the higher standard of living it brings have grown along with the population.
