Electricity in Europe: exiting fossil fuels?
探讨欧洲电力行业退出化石燃料的挑战与可能路径,指出可再生能源难以完全替代化石燃料,天然气在碳捕集与封存技术下仍有长期作用,对政策制定者和能源研究者有参考价值。
There are many options for generating electricity with low carbon emissions, and the electrification of heat and transport can decarbonize energy use across the economy. This places the power sector at the forefront of any move away from fossil fuels, even though fossil-fuelled generators are more dependable and flexible than nuclear reactors or intermittent renewables, and vital for the secondby-second balancing of supply and demand. Renewables tend to supplement, rather than replace, fossil capacity, although output from fossil-fuelled stations will fall and some will have to retire to avoid depressing wholesale power prices. At times of low demand and high renewable output prices can turn negative, but electricity storage, long-distance interconnection, and flexible demand may develop to absorb any excess generation. Simulations for Great Britain show that while coal may be eliminated from the mix within a decade, natural gas has a long-term role in stations with or without carbon capture and storage, depending on its cost and the price of carbon.
