Shore power reduces emissions

摘要

Norway and North Sea operators want to use shore power offshore if they can justify the cost. Now they can. Norway could see huge environmental gains in terms of sharply reduced CO{sub}2 and NOX emissions if it could supply electric power to offshore platforms from onshore bases, but the economics just won't cooperate in most cases. The basics are simple. Offshore power generators on platforms work at up to 25% efficiency and produce a lot of emissions in the process. Onshore combined-cycle plants, which use fuel for primary burning and use the heat from that process for additional power generation, work at up to 80% efficiency.
