Quest One, a leading electrolyzer manufacturer, and MasTec Clean Energy & Infrastructure (CE&I), a major infrastructure construction company, have signed a memorandum of understanding (MoU) for a partnership to accelerate the development and deployment of green H₂ solutions in North America. The non-exclusive strategic collaboration focuses on optimizing the construction of large-scale electrolysis projects.

Through the partnership, Quest One and MasTec CE&I aim to collaborate on standardized and streamlined constructability concepts for industrial-scale proton exchange membrane (PEM) electrolysis plants to reduce overall project capital costs and risks.

Both companies believe their collaborative approach will be key to improving the green H₂ value chain. “As green H₂ projects scale to hundreds of megawatts, the impact of plant site construction becomes increasingly critical for enabling project bankability and financing,” said Jaryd O’Brasky, Vice President of Customer Operations at Quest One North America.

“At Quest One, we strongly believe in proactive collaboration with EPC’s to ensure our electrolyzer plants are designed for optimized constructability. Our modular H₂ platform (MHP) is engineered and manufactured to maximize prefabrication and minimize onsite installation complexity. Combined with MasTec’s extensive expertise in renewable energy and infrastructure construction, our goal is to further reduce costs and schedule risks at the plant level for our customers.”

"We’re excited to join forces with Quest One to advance green H₂ solutions across North America," said Chris McGahee, Executive Vice President of Industrial at MasTec CE&I. "Our extensive experience in large-scale construction and complex infrastructure makes this partnership a seamless fit for our commitment to sustainable energy. By enhancing our expertise in electrolyzer plant construction, we’re focused on reducing costs, optimizing constructability, and accelerating project timelines to drive the future of green H₂."

Industrial-scale H₂ production. The MHP is currently the largest PEM electrolyzer in Quest One's product portfolio. Its scalable modular system makes it particularly suitable for industrial production of green H₂. Module blocks with an input of 10 megawatts can be expanded and combined to create plants with an electrolysis capacity from 10 to several hundred megawatts. The system is optimized for installation on preassembled skids and manufactured in the U.S. for the North America market.
