The Economist was recently citing hydrogen as "deep tech" [1] (meaning long R&D cycles, sometimes unproven techniology no short term profitability, heavy investment, industry-wide transformative power).

Most of your sources have plans focused on hydrogen production, but I'd be interested to see specific targets or plans regarding specific uses like fertilizers. There are some in the Hydrogen Roadmap Europe, but it seems focused on transportation [2].
