Coal and Natural Gas |
Coal is the most important fuel in our energy mix. At year end 2007, we had 18.8 GW of hard coal-fired generating capacity. The thermal efficiency of hard coal-fired generating units must be improved in order to minimize this fuel’s negative impact on the environment. That’s why we plan to build the world’s first coal-fired generating unit with a thermal efficiency of more than 50 percent. We expect this unit to enter service in 2014. We’re also spurring the development of low-emission coal-fired generating units. Our commitment to innovation strengthens our competitive position and helps us maintain our position as a technology pacesetter.
Lignite-fired generating units are also used, and have a comparatively low level of thermal efficiency, emitting large amounts of carbon dioxide. Lignite is of little significance in the E.ON portfolio. At year end 2007, we had 1.3 GW of lignite-fired generating capacity which represents only a small part of the generation portfolio.
Despite the CO2 advantages of gas-fired generation, we do not expect to significantly increase the share of natural gas in our energy mix between now and 2015. This is because it is more suited to covering peak and mid load than baseload. Instead we aim to promote the use of natural gas as a vehicle fuel more heavily. E.ON Ruhrgas is committed to expanding the network of gas stations which stock natural gas. Incentive schemes will also be launched to encourage the use of natural gas as a fuel and for natural gas to be considered more in automotive production.
