Puget Sound Energy has signed a joint development agreement with Mitsubishi Power Americas, Inc. to collaborate on project development and technology solutions in line with PSE’s goal to become a “Beyond Net Zero Carbon” energy company by 2045.

This agreement will help enable the implementation of large scale, carbon-free renewable generation and storage into PSE’s service territory while continuing to meet customer expectations for uncompromised reliability, safety and affordability. Key areas of focus for the partnership will include:

•   Developing green hydrogen production, storage and transportation facilities
•   Developing hydrogen gas turbine combined cycle facilities and utility scale battery storage systems 
• Collaborating to pursue cross-sector decarbonization opportunities to create synergies between the power sector and other industrial sectors in the region, including refineries, transportation and distribution

Additionally, under terms of the agreement, Mitsubishi Power and Magnum Development will jointly develop green hydrogen storage assets in PSE’s service territory. Mitsubishi Power and Magnum Development introduced green hydrogen storage at grid scale in May 2019 with the Advanced Clean Energy Storage Project in Delta, Utah.

"It is our firm belief that to achieve net zero carbon emissions by 2045, we need to develop and deploy renewable energy storage projects of all durations in the decade of the 2020s," said Paul Browning, President and CEO of Mitsubishi Power Americas, said. "This means lithium ion battery storage for short-duration storage, and green hydrogen for long-duration storage."
