An IGCC or “clean coal” plant actually combines three distinct technologies – a gasifier, a combustion turbine and a steam turbine. In the first phase, gasification, coal is heated to produce a gas. In phase two the gas turns a turbine (similar to a high-powered airplane engine) to make electricity. In phase three the excess heat from the turbine is captured and used to boil water to make steam, which is then used to make electricity. [PDF]
Issues: Climate Change
Human-induced global warming poses perhaps the greatest threat ever to our very survival and that of countless other plant and animal species across the globe. To achieve the cuts in emissions in carbon dioxide and other global-warming pollutants needed to avoid the most dire consequences of climate change, we must stop relying on carbon-emitting fossil-fueled power plants for our electricity. In addition to promoting clean energy choices by utilities and regulatory agencies, the NW Energy Coalition is actively engaged in state and regional processes aimed at economy-wide cuts in carbon pollution.
