據路透社4月8日東京報道，日本工業部周四表示，日本和阿拉伯聯合酋長國同意在氫生產技術上展開合作，并建立一個國際供應鏈。

這項合作以石油生產國阿聯酋與能源進口國日本之間的合作備忘錄為標志，反映出對投資氫能源的熱情日益高漲，這為幫助應對氣候變化提供了潛力。

去年12月，日本政府設定了一個目標，到2030年將其氫需求從現在的約200萬噸/年提高到300萬噸/年，到2050年提高到2000萬噸，這是到2050年實現碳凈零排放的綠色增長戰略的一部分。

周四達成協議的目的是，日本能夠進口阿聯酋生產的氫，這種氫可能由化石燃料生產，但其碳排放會被捕集并用于工業。

兩國還將合作促進阿聯酋的氫需求。

氫主要從天然氣或煤炭生產中提取，長期以來一直用于從火箭燃料到制造肥料的各種應用中。

但隨著各國政府尋求解決氣候變化問題，其目標是轉向使用可再生能源生產的無排放綠色氫，并擴大其用途，包括在工業過程中取代化石燃料能源，并將其用作交通燃料。但在成本和基礎設施方面仍存在許多障礙。

Japan, UAE to collaborate on hydrogen technology, supply chain

Japan and the United Arab Emirates on Thursday agreed to work together on technology to produce hydrogen and create an international supply chain, Japan’s industry ministry said.

The collaboration, marked by a memorandum of cooperation between the oil-producing UAE and energy-importer Japan, reflects mounting enthusiasm for investment in hydrogen, which offers potential to help fight climate change.

Japan’s government set a goal in December to boost its annual hydrogen demand to 3 million tonnes by 2030, from about 2 million tonnes now, and to 20 million tonnes by 2050, as part of a green growth strategy to reach net zero carbon emissions by 2050.

The aim of Thursday’s agreement is that Japan should be able to import hydrogen produced in the UAE, which may be produced from fossil fuel but whose emissions are captured and used in industry.

The two countries will also cooperate to boost hydrogen demand in the UAE.

Hydrogen, mostly extracted from natural gas or coal production, has long been used in applications ranging from rocket fuel to making fertilisers.

But as goverments seek to address climate change, the goal is to shift to emissions-free green hydrogen produced using renewable power and to broaden its use to include replacing fossil fuel energy in industrial processes and using it as transport fuel. But there are still many hurdles involving cost and infrastructure.
