Exxon Mobil and Marubeni have entered a significant long-term offtake agreement to supply 250,000 metric tons of low-carbon ammonia annually, leveraging a potentially largest low-carbon hydrogen facility in Baytown, Texas. The deal, contingent on Exxon's final investment decision, aims to support global emission reduction efforts by utilizing American natural gas to create low-carbon ammonia for Japan. This partnership signals a positive step towards decarbonization, with plans to broaden hydrogen applications beyond petroleum refining and ammonia production. Most of the produced low-carbon ammonia is destined for the coal-fired Kobe Power Plant in Japan to co-fire with existing sources, contributing to emission reduction initiatives. Marubeni's commitment includes acquiring a stake in Exxon's hydrogen and ammonia facility, laying the groundwork for continued collaboration in decarbonization projects. Additionally, the article touches on other renewable energy news, highlighting the substantial growth in sustainable aviation fuel and biofuels production in the U.S., as well as the achievement of net-negative carbon emissions by HutanBio's microalgal biofuel technology.
