Drax Fights for its Future - Power Technology
Drax now effectively converts around 10m tonnes of coal per year into 24,000 GWh/year of electricity plus over 20m tonnes of carbon dioxide. Coal generates far more CO 2 per unit of electricity than any other fuel, and Drax was responsible for many of the emissions that went to label the UK as 'the dirty man of Europe' in the 1990s.
