Energy Company Expanding Facility In Wallingford

WALLINGFORD, CT — A Norwegian-based renewable energy company is expanding its manufacturing facility in Wallingford, officials announced this week.

Nel ASA, which was founded in 1927 and is based in Oslo, has taken the “final investment decision” to expand the production capacity at its PEM electrolyser manufacturing facility in Wallingford. The expansion will bring annual production capacity “towards 500 MW in 2025,” according to a news release.

“This is an important milestone for Nel,” Nel’s CEO Håkon Volldal said in a news release. “With this expansion, we will increase PEM production capacity substantially and simultaneously reduce stack cost and improve stack efficiency.”

The new production line is expected to reach nameplate capacity in 2025, according to the release.

“Last year we opened the world's first fully automated alkaline electrolyser plant in Herøya, Norway,” Volldal said. “Now we will industrialize the PEM platform, and the expansion in Wallingford is an important first step.”

The development of the “~500 MW PEM production line will be a substantial contributor to further expansion plans” in the U.S., according to the news release.
