欧洲绿氢生产比蓝氢和灰氢更经济

　　据氢能源新闻10月19日消息称，天然气和碳的高价格使得使用可再生能源生产氢气的成本更低。

 

　　随着二氧化碳价格达到创纪录水平，天然气价格继续上涨，在欧洲，绿色氢生产比蓝色和灰色氢更便宜。

 

　　新的计算表明，捕获和储存比排放更便宜。

 

　　虽然造成二氧化碳空气污染的费用从未如此之高，但天然气的价格已经达到了使用可再生能源生产绿色氢气是一种相对负担得起的选择。

 

　　欧盟的碳价格为创纪录的每吨60欧元（69美元），这使得使用天然气制造的灰色氢在没有任何碳捕获的情况下制造的成本将大大高于蓝色氢气，它也是由天然气制成的，但它使用碳捕捉和储存来减少温室气体的排放。也就是说，欧洲还没有任何蓝色氢生产。

 

　　澳大利亚的Keynumbers和Energy Flux服务计算出，在实际使用情况下，目前制造绿色氢气的平均成本约为每公斤4.18欧元。相比之下，根据他们在通讯中公布的计算结果，目前灰色氢气每公斤售价为6.55欧元，蓝色氢气每公斤价格为6.21欧元。

　　European green hydrogen production is cheaper than blue and grey

 

　　The high price of natural gas and carbon have made it so H2 produced with renewable energy is more affordable.

 

　　As CO2 prices reach record levels and the price of natural gas continues to rise, green hydrogen production has become cheaper in Europe than blue and grey forms of H2.

 

　　New calculations have shown that it’s cheaper to capture and store the emissions than to release it.

 

　　While the expense associated with causing CO2 air pollution has never been higher, the price of natural gas has reached the point that using renewable energy for green hydrogen production is a comparatively affordable option.

 

　　The EU carbon price at a record €60 per tonne (USD$69) makes it so that grey H2 made using natural gas without any carbon capture would be substantially more expensive to make than blue H2, which is also made with natural gas, but that uses carbon capture and storage to reduce the greenhouse gas emissions. That said, there has yet to be any blue H2 made in Europe.

 

　　Keynumbers and the Energy Flux services in Australia calculated that under real use circumstances, the levelized cost of making green H2 would currently be about €4.18 per kilogram. Comparatively, it would currently cost €6.55 per kilogram for grey H2 and €6.21 per kilogram for blue H2, according to the calculations they published in their newsletter.
