据今日油价网站10月6日消息 国际能源署(IEA)在一份新报告中表示,在世界正在向清洁能源迈进的同时,在化石燃料发电厂中使用低碳氢和氨可能是确保电力供应安全的关键。然而,该机构指出,低碳氢和氨燃料的生产成本需要大幅降低,才能与包括化石燃料在内的其他形式的能源竞争。


IEA在其报告中表示,低碳燃料在热电机组起步较晚的国家或地区,或低碳可调度资源的可用性受到限制时,例如在东亚和东南亚,可以发挥尤为重要的作用。


IEA指出:“到2030年,用作化工原料的低碳氢气和氨气的成本将与化石燃料生产的成本相当。但是,作为燃料使用,预计其价格仍将远高于《可持续发展愿景(SDS)》中2030年煤炭和天然气的预计价格。”


IEA表示,到本世纪末,低碳氢和氨很可能仍然是昂贵的发电能源载体。


该机构的调查结果还表明,需要一系列政策来弥补成本缺口。


IEA在本月早些时候发布的《2021年全球氢气审查》中表示,政府必须采取果断行动支持低碳氢气。


该机构表示,对氢气的投资正在增长,而且兴趣很高,但需要额外的支持政策来降低生产成本,并鼓励各行业使用氢气。


IEA执行主任法提赫·比罗尔表示:“各国政府需要迅速采取行动,降低阻碍低碳氢气快速增长的障碍,这对于世界到2050年实现净零排放至关重要。”

IEA: Low-Carbon Hydrogen Needs Major Cost Cuts


The use of low-carbon hydrogen and ammonia in fossil fuel plants could be key to ensure security in electricity supply while the world is moving toward cleaner energy sources, the International Energy Agency (IEA) said in a new report. The agency noted, however, that production costs of low-carbon hydrogen and ammonia fuels need to fall significantly in order to be competitive with other forms of energy, including fossil fuels.


Low-carbon fuels can play an especially important role in countries or regions where the thermal fleet is young, or when the availability of low-carbon dispatchable resources is constrained, for example in East and Southeast Asia, the IEA said in its report.


“By 2030 the cost of low-carbon hydrogen and ammonia for use as chemical feedstock becomes comparable to those of unabated production from fossil fuels. However, for use as a fuel, they are expected to remain significantly more expensive than projected prices of coal and natural gas in 2030 in the SDS [Sustainable Development Scenario],” the international agency noted.


By the end of this decade, low-carbon hydrogen and ammonia are likely to remain expensive energy carriers for power generation, the IEA says.


The agency’s findings also suggest that “a portfolio of policies is required to compensate for cost gaps.”


Decisive government action is necessary to support low-carbon hydrogen, the IEA said in its Global Hydrogen Review 2021 earlier this month.


Investments in hydrogen are growing, and interest is high, but additional supportive policies are needed to reduce production costs and incentivize hydrogen usage in various sectors, the agency said.


“Governments need to take rapid actions to lower the barriers that are holding low-carbon hydrogen back from faster growth, which will be important if the world is to have a chance of reaching net zero emissions by 2050,” the IEA Executive Director Fatih Birol said.
