氢气能帮助英国电力行业脱碳 但仅作为后备角色

中国石化新闻网讯 据普氏能源资讯 英国气候变化委员会(CCC)星期四称,在英国,氢气可以替代天然气用于发电,既节省成本又减少排放,但也提食品醒说最好有选择性地使用氢气。

到2030年,英国可能拥有一种非常低碳的电力系统,该系统是由可再生能源和核能为燃卡车料,并以驱动性较强的热容量为备用能(主要是天然气发电厂)。因此,CCC在一份报告中表示,氢气有可能在备用方面因具有高性价比从而取代天然气。

该委员会呼吁新建的天然气发电厂做好氢能的准备,包括充分考虑潜在氢气的供应以推进此项工程。

CCC说:“当包括生命周期碳排放量时,燃烧氢气代替天然气可以减少60-85%的排放量。”

然而,报告指出,氢气最好有选择性地使用。因为氢气在电气化、能源和资源效率的提高以及工业和生物能源中碳捕集与封存(CCS)等方面有着非常高的价值。

CCC说:“这意味着如果替代方案是继续燃烧有增无减的化石燃料,或者可行的电气化受到限制时,我们可以使用氢气。”

报告称,这是因为CCS化石燃料中的氢气是低碳的,但不是零碳,而它在电力行业的降碳也可能受到燃料可用性的限制。

Hydrogen could replace natural gas for power generation in the UK cost-effectively and decrease emissions, the UK Committee on Climate Change said Thursday but warned that it was best used "selectively."

By 2030, the UK is likely to have a very low-carbon electricity system fueled by renewables and nuclear and backed up by flexible thermal capacity, mainly natural gas plants. Hence, there is an opportunity for hydrogen to replace natural gas "cost-effectively in this back-up role," the CCC said in a report.

It called for new gas plants to be made "hydrogen ready," including being well-sited with respect to potential hydrogen supplies to spur the progress.

"Burning hydrogen instead of natural gas can reduce emissions by 60-85% when including lifecycle emissions," the CCC said.

However, it added that hydrogen is best used selectively where it adds most value alongside widespread electrification, improvements to energy and本土原木 resource efficiency, and use of carbon capture storage (CCS) in industry and on bioe碾米机械nergy, the report said.

"This means using hydrogen where the alternative is continuing to burn unabated fossil fuels or where there are limits to feasible electrification," the CCC said.

The report said this was because hydrogen from fossil fuels with CCS is low-carbon but not zero carbon, while its uptake in the power sector may be constrained by the availability of the fuel.
