AVANGRID puts forward green hydrogen project concepts

Published by
Energy Global,

AVANGRID Inc., a sustainable energy company, announced that 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.

“We believe the time for green hydrogen as a viable clean energy fuel has come,” AVANGRID CEO Dennis V. Arriola said. “Our partners at Iberdrola in Spain and at ScottishPower in the UK are already developing commercial scale green hydrogen projects. For example, Iberdrola is building the largest plant producing green hydrogen for industrial use in Europe. AVANGRID’s access to this global expertise, combined with our US-based partners and supporters, provides us with a unique advantage to help accelerate the commercial production of green hydrogen in the US”.

Multiple project concepts submitted by AVANGRID as part of the RFI are outlined below.

Connecticut – electrolyser and hydrogen storage

One of AVANGRID’s RFI responses proposes constructing a 20 MW electrolyser 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 emissions reduction of approximately 25 000 tpy of CO2 and potentially creating 400 - 800 jobs in economically disadvantaged communities.

New York – utilising 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.

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

Representing its nationwide presence and leading renewables fleet, Avangrid Renewables has additionally identified opportunities to support green hydrogen for industrial use on the Gulf Coast and provide cleaner solutions that strengthen the US’s domestic energy leadership.

For instance, 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 ambitious 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

In Oregon, 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 1300 MW Northwest wind farm fleet. The proposed project would include an approximately 20 MW electrolyser to enable a 2% blend of green hydrogen into the plant’s fuel supply. This project has the potential to generate 3000 tpy of green hydrogen.

The DOE’s RFI seeks information from industry, investors, developers, academia, research laboratories, government agencies, and other stakeholders on potential hydrogen demonstration projects in the US. It is part of the DOE’s recently announced Energy Earthshot Initiative to accelerate breakthroughs of more abundant, affordable, and reliable clean energy solutions within the decade.
