●＜海外・提携＞NUCORがGoogle、Microsoftとクリーン電力供給で新イニシアチブ
＊（2024/3/19 NUCOR）GOOGLE, MICROSOFT, AND NUCOR ANNOUNCE A NEW INITIATIVE TO AGGREGATE DEMAND TO SCALE THE ADOPTION OF ADVANCED CLEAN ELECTRICITY TECHNOLOGIES
The companies will work to address barriers to early-stage commercial project deployment.
Google LLC, Microsoft Corporation, and Nucor Corporation today announced they will work together across the electricity ecosystem to develop new business models and aggregate their demand for advanced clean electricity technologies. These models will be designed to accelerate the development of first-of-a-kind (FOAK) and early commercial projects, including advanced nuclear, next-generation geothermal, clean hydrogen, long-duration energy storage (LDES) and others. As a first step, the companies will issue an RFI in several US regions for potential projects in need of offtake, and encourage technology providers, developers, investors, utilities and others interested in responding to get in touch here.
