![]() ![]() It involves the geological storage of CO 2, typically 2-3 km deep, as a permanent solution. Alongside nuclear power and harnessing renewable energy sources, one hope for this is via 'clean coal' technologies, such as carbon capture and sequestration, also called carbon capture and storage (both abbreviated as CCS) or carbon capture, use and storage (CCUS). Much of the challenge is in commercialising the technology so that coal use would remain economically competitive despite the cost of achieving low, and eventually 'near-zero', emissions. The technologies are both costly and energy-intensive.Īs many coal-fired power stations approach retirement, their replacement gives much scope for 'cleaner' electricity. However, each year burning coal produces over 15 billion tonnes of carbon dioxide (CO 2), which is released to the atmosphere, most of this being from power generation.ĭevelopment of new 'clean coal' technologies is attempting to address this problem so that the world's enormous resources of coal can be utilised for future generations without contributing to global warming. Globally about 2000 GWe of coal-fired generation capacity is operating and another 500 GWe is expected online by 2030. Coal is the world's most abundant and widely distributed fossil fuel source. Some 26% of primary energy needs are met by coal and 37% of electricity is generated from coal, compared with 23% for natural gas. The term 'clean coal' is increasingly being used for supercritical coal-fired plants without CCS, on the basis that CO 2 emissions are less than for older plants, but are still much greater than for nuclear or renewables.World R&D on CCS exceeded $1 billion per year over 2009 to 2013, then fell sharply.There is typically at least a 20% energy penalty involved in 'clean coal' processes.The greatest challenge is bringing the cost of this down sufficiently for 'clean coal' to compete with nuclear power on the basis of near-zero emissions for base-load power.Attempting to use coal without adding to atmospheric carbon dioxide levels is a major technological challenge.Burning coal produces about 15 billion tonnes of carbon dioxide each year.Coal is used extensively as a fuel in most parts of the world.Massachusetts Institute of Technology, Climate Portal.'Clean Coal' Technologies, Carbon Capture & Sequestration Department of Energy, National Energy Technology Laboratory. “ Biden-Harris Administration Announces Up to $1.2 Billion for Nation’s First Direct Air Capture Demonstrations in Texas and Louisiana.” “ Fact Sheet: Biden-Harris Administration Advances Cleaner Industrial Sector to Reduce Emissions and Reinvigorate American Manufacturing.” “ How (and Why) to Boost Carbon Capture, Usage and Storage to Move Towards Net Zero.” “ Carbon Capture, Utilisation and Storage.” “ Popularization of Carbon Capture and Storage Technology in Society: Principles and Methods.” International Journal of Environmental Research and Public Health, Vol. “ The Carbon Capture Scam.”Īlexey Cherepovitsyn, Tatiana Chvileva, and Sergey Fedoseev, via National Center for Biotechnolgy Information. “ Carbon Removal Hype Is Becoming a Dangerous Distraction.”įood & Water Watch. “ Climate Change 2023 Synthesis Report: Summary for Policymakers,” ( of PDF).
