Washington State’s first large-scale green hydrogen production facility uses power from the Wells Dam to produce hydrogen through membrane electrolysis, creating a zero-emission fuel source while reducing generator unit maintenance costs. As one of the first large-scale applications of this type of hydrogen production in the region, this project is laying groundwork for the owner’s long-term hydrogen strategy.
Green hydrogen produced at this facility can power fuel cell electric vehicles and generators that supply power to the grid. Scope included construction of a 5-megawatt facility with a 12,000-sq-ft precast tilt-up building, structural steel interior framework, extensive mechanical piping and hydrogen production equipment. The facility’s infrastructure is capable of eventually supporting up to 80 megawatts of green hydrogen production.

With the owner pioneering an emerging market and driving exploration and innovation in green hydrogen technology, engineering was still in progress during procurement and bidding, with piping layouts and facility-wide piping and instrumentation diagrams at approximately 65% design completion when construction began. The team collaborated closely to finalize design, working through weekly design resolution meetings and construction planning sessions. During construction, the team received an average of three owner-directed changes each week, but thanks to strong teamwork and consistent transparent communication, the $23-million project was completed on time and within budget in May 2025.
Erecting the tilted precast building near active overhead power lines required heightened planning and precision. The contractor brought on Washington State Labor & Industries as a consultant to ensure the crane pick plan met all regulatory and safety standards. Flaggers were stationed during crane operations near power lines to maintain safe clearances and situational awareness. Crews also focused on precise installation of miles of pipe tubing throughout the site’s tight footprint. Identifying constructibility issues early and proactively resolving them before installation minimized rework and controlled costs.
