到2050年绿色氢将占欧洲电力需求的20%

　　中国石化新闻网讯 据能源经济10月21日消息称，挪威电力公司Statkraft周四发布的一份报告显示，到2050年，由可再生能源生产的氢气将占欧洲电力消耗的20%，占全球电力消耗的10%。

　　绿色氢是在电解器中用可再生电流分解水分子产生的。这种气体被吹捧为难以脱碳的工业中化石燃料的清洁替代品。

　　Statkraft的第六次年度低排放情景报告显示，到2050年，欧洲电力需求将上升至略高于5,000太瓦时(TWh)，绿色氢生产将占约1,000太瓦时，高于目前约30太瓦时的需求。

　　该公司是欧洲最大的可再生能源生产商之一，在德国还运营着几家天然气工厂。它将其对低排放情景的分析作为未来投资的基础。

　　该研究发现，到2050年，全球电力需求可能会增加一倍以上，达到略高于6万太瓦时，因为电气化被视为减少二氧化碳排放的主要工具，而可再生能源满足了约80%的需求。

　　目前，绿色氢气生产比传统的化石燃料生产成本更高，但Statkraft表示，这种情况将会改变。

　　该公司预计，到2050年，电解槽的投资成本将下降60%，再加上存储能力，可以确保工业的稳定供应。

　　报告称：“季节性储存在不同季节之间存在巨大电价差异的市场中是有益的，例如在欧洲。”

　　Green hydrogen to account for 20% of European power demand by 2050

　　Hydrogen produced from renewable energy sources will account for 20% of Europe's power consumption in 2050, and for 10% globally, a report published by Norwegian power company Statkraft on Thursday showed.

　　Green hydrogen is produced by splitting water molecules with a current of renewable electricity in electrolysers. The gas is touted as a clean replacement for fossil fuels in industries that are otherwise hard to decarbonise.

　　European power demand will rise to just over 5,000 terawatt hours (TWh) in 2050, with green hydrogen production accounting for around 1,000 TWh, up from current demand of around 30 TWh, Statkraft's sixth annual Low Emissions Scenario report showed.

　　The company is one of Europe's largest renewable energy producers and also operates several gas plants in Germany. It uses its analysis from the Low Emissions Scenario as the foundation for future investments.

　　Global power demand will likely more than double by 2050 to just over 60,000 TWh as electrification is seen as the main tool to reduce carbon dioxide emissions with renewable energy meeting about 80% of that demand, it found.

　　At present, green hydrogen production is more expensive than traditional production from fossil fuel sources, but Statkraft said that would change.

　　The company expected investment costs for electrolysers to fall by 60% by 2050, which coupled with storage could ensure a steady supply for industry.

　　"Seasonal storage can be beneficial in markets with significant power price differences between seasons, for example in Europe," the report said.
