Green hydrogen production is a crucial aspect of the global decarbonization effort, but it faces challenges in scaling up due to the expensive and cumbersome manufacturing process of electrolyzer systems. To address this issue, industry stakeholders, including the U.S. firm 3M, are exploring innovative manufacturing strategies. 3M's extensive experience in roll-to-roll manufacturing, initially developed for products like recording tapes, is now being applied to revolutionize electrolyzer manufacturing. The rapid and cost-effective nature of roll-to-roll systems holds immense potential for reducing the cost of green hydrogen production and making it more competitive with conventional fossil resources. The U.S. Department of Energy promotes roll-to-roll systems as a key element in scaling up renewable energy technologies. The goal is to significantly reduce the cost of green hydrogen, aiming for $1.00 per kilogram by 2031. 3M's venture capital arm has invested in Evoloh, a company developing a roll-to-roll system for manufacturing low-cost electrolyzer stacks. Evoloh's innovative approach includes using locally sourced materials and plain tap water to cut costs. This support from industry leaders and government entities demonstrates a positive outlook for the future of green hydrogen production, with a focus on cost reduction, innovation, and sustainability.
