Most claims regarding market size, dominant firms, barriers to entry, company histories, and current hydrogen projects are consistent with verifiable public data up to late 2025. Recent events described, such as green hydrogen projects and industry metrics, correspond with major industry reporting within the past year. However, certain figures—like the exact share held by the top three firms and specific details on project scales and contract terms—are not directly sourced or may vary slightly across different industry reports.
