Guidehouse Insights has released a report assessing the competitive landscape for electrolyzer vendors in the green hydrogen market. The report recognizes John Cockerill, thyssenkrupp nucera, and Nel Hydrogen as the current leading vendors. It discusses the substantial growth and investment in the electrolyzer industry in response to policy support, interest from hard-to-abate sectors, and increasing competition among manufacturers. The report emphasizes that electrolyzers are crucial for producing green hydrogen using renewable electricity and notes the emergence of a significant pipeline of green hydrogen projects, particularly in their early development stages. The scope of services offered by electrolyzer vendors varies from dedicated stack suppliers to end-to-end players with advanced integration and engineering capabilities. The report also cautions that not all vendors are likely to be successful in the long term. Success factors include scaling in line with market demand, technology performance, cost reductions, and alignment with customer needs. Guidehouse Insights' Leaderboard assesses 16 prominent European and North American vendors across key metrics to clarify their competitive position in the green hydrogen industry. The report leverages primary research and a database of global hydrogen electrolyzer projects. An executive summary of the report is available for download on the Guidehouse Insights website.
