Avangrid, a sustainable energy company, announced July 8 it has submitted multiple responses as part of the U.S. Department of Energy’s Request for Information (RFI) on ways to enable low-cost clean hydrogen at scale, outlining green hydrogen concepts for Connecticut, New York, Maine, Oregon, and the Gulf Coast.

Multiple project concepts submitted by Avangrid as part of the RFI include:

New York – Utilizing Hydrogen for Transportation in Rochester

In collaboration with local area transportation authorities in Rochester, New York, Rochester Gas & Electric (RG&E) is assessing opportunities to construct a multi-use hydrogen production and distribution facility, which could support a range of hydrogen uses, including transportation applications to meet zero-emissions fleet goals.

Connecticut -- Electrolyzer and Hydrogen Storage

One of Avangrid’s RFI responses proposes constructing a 20 MW electrolyzer and hydrogen storage facility for its Connecticut gas and electric utilities, potentially powered by renewable energy from offshore wind and supplemented by additional solar or grid-based renewable electricity. It is estimated the project could produce roughly 2.9 million kg of hydrogen per year, yielding an annual emissions reduction of approximately 25,000 tons of CO2 and potentially creating 400 – 800 jobs in economically disadvantaged communities.

Maine – Exploring Hydrogen for Multiple Applications

In Maine, Avangrid’s local subsidiary, Central Maine Power (CMP), has begun exploring how to collaboratively help advance green hydrogen consumption in existing manufacturing processes, for enhanced renewable natural gas production, and in transportation applications such as trucking and aviation.

Gulf Coast – Leveraging Avangrid Renewables Wind Generation to Develop Green Hydrogen and Green Ammonia

Avangrid Renewables has additionally identified opportunities to support green hydrogen for industrial use on the Gulf Coast and provide cleaner solutions that strengthen the U.S.’s domestic energy leadership.

A large-scale electrolysis project in Corpus Christi, Texas, would convert low-cost Texas wind power into green hydrogen and ultimately into green ammonia. The commercial-scale project demonstrates the scalability of the technology, its path to cost-competitiveness, and green hydrogen’s value as an important component in an economywide clean energy transition.

Oregon – Leveraging Klamath Cogeneration Plant for Hydrogen Production

Avangrid’s RFI response proposes the colocation of green hydrogen production at Avangrid Renewables’ Klamath Cogeneration Plant. The intent would be to make the facility a source for fuel flexibility as the combined-cycle natural gas plant balances the intermittency of the energy generated by Avangrid’s 1,300 MW Northwest wind farm fleet. The proposed project would include a ~20 MW electrolyzer to enable a two percent blend of green hydrogen into the plant’s fuel supply. This project has the potential to generate 3,000 metric tons of green hydrogen annually.
