據烴加工新聞5月23日消息稱，三菱電力美洲公司和德州Brine已簽署協議，開發大規模的長期氫儲存解決方案，以支持美國東部的脫碳努力。氫的長期儲存是向零碳能源過渡的關鍵技術。

　　此次合作擴大了三菱電力公司在北美戰略位置的鹽穴中安全、經濟地儲存氫氣的能力。德州Brine及其附屬公司在紐約、弗吉尼亞、德克薩斯和路易斯安那州擁有鹽場，這將使其能夠進入東北部、中大西洋和墨西哥灣沿岸的主要裝載中心。

　　鹽礦床是一種獨特的地質特征，可以通過開采溶洞來提供安全、可靠和經濟的儲氣庫。氫氣在美國墨西哥灣沿岸的鹽洞中儲存了數十年。在其他地區擴大鹽穴用于氫能源儲存的使用，為在美國各地建立清潔能源基礎設施提供了一個重要機會，使電力、交通和制造業等以凈零碳排放為目標的行業受益。

　　德州Brine的合作通過在靠近項目的地方設置大規模的氫存儲，使其能夠獲得經濟的公用事業規模的可再生能源存儲，從而補充了三菱電力不斷增長的氫準備燃氣渦輪機組合。

　　三菱電力與德州Brine的合作還提供了其他共生利益。鹽水是鹽和水的混合物，在鹽層的溶液開采過程中產生。然后它可以被用作化學工業的關鍵原料，或者它可以被脫水生產鹽，用于食品、除冰、農業、工業和水軟化市場。溶液開采過程的副產品是一個地下儲存庫，可以用來儲存液體或氣態商品，如氫。

　　Mitsubishi Power and Texas Brine join forces for large-scale hydrogen storage

　　Mitsubishi Power Americas Inc., and Texas Brine Co. LLC have signed an agreement to develop large-scale long-duration hydrogen storage solutions to support decarbonisation efforts across the eastern US. Long-duration hydrogen storage is a key enabling technology for the transition to a net zero carbon energy future.

　　This collaboration expands Mitsubishi Power’s capability to store hydrogen safely and cost effectively in salt caverns in strategic locations across North America. Brine producer Texas Brine and its affiliates have salt positions in New York, Virginia, Texas and Louisiana that will enable access to major load centres in the Northeast, Mid-Atlantic and the Gulf Coast.

　　Salt deposits are unique geological features into which caverns can be solution mined to provide safe, reliable and economical bulk gas storage. Hydrogen has been stored in salt caverns for decades in the US Gulf Coast. Expanding the use of salt caverns for hydrogen energy storage in other regions offers a significant opportunity to create an infrastructure for clean energy resources throughout the US to benefit industries such as power, transportation and manufacturing that are targeting net zero carbon emissions.

　　The Texas Brine collaboration complements Mitsubishi Power’s growing portfolio of hydrogen-ready gas turbines by positioning large-scale hydrogen storage in close proximity to projects, enabling access to economical utility-scale renewable energy storage.

　　Mitsubishi Power’s collaboration with Texas Brine provides other symbiotic benefits. Brine, a mixture of salt and water, is produced during the solution mining of salt formations. It can then be used as a critical feedstock for the chemical industry, or it can be dehydrated to produce salt for food, deicing, agricultural, industrial, and water softening markets. The coproduct of the solution mining process is an underground repository that can be used to store liquid or gaseous commodities, such as hydrogen.
