      歐洲綠氫生產比藍氫和灰氫更經濟

        據氫能源新聞10月19日消息稱,天然氣和碳的高價格使得使用可再生能源生產氫氣的成本更低。
       
        隨著二氧化碳價格達到創紀錄水平,天然氣價格繼續上漲,在歐洲,綠色氫生產比藍色和灰色氫更便宜。
       
        新的計算表明,捕獲和儲存比排放更便宜。
       
        雖然造成二氧化碳空氣污染的費用從未如此之高,但天然氣的價格已經達到了使用可再生能源生產綠色氫氣是一種相對負擔得起的選擇。
       
        歐盟的碳價格為創紀錄的每噸60歐元(69美元),這使得使用天然氣制造的灰色氫在沒有任何碳捕獲的情況下制造的成本將大大高于藍色氫氣,它也是由天然氣制成的,但它使用碳捕捉和儲存來減少溫室氣體的排放。也就是說,歐洲還沒有任何藍色氫生產。
       
        澳大利亞的Keynumbers和Energy Flux服務計算出,在實際使用情況下,目前制造綠色氫氣的平均成本約為每公斤4.18歐元。相比之下,根據他們在通訊中公布的計算結果,目前灰色氫氣每公斤售價為6.55歐元,藍色氫氣每公斤價格為6.21歐元。

        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.
