It also stresses that regulators can make smarter decisions on these issues by widening their aperture of awareness to consider -- and coordinate with other agencies and authorities on -- other issues affecting hydrogen's growth that may fall outside of their direct decision-making power.

The roadmap pulls together insights from a collaborative process involving two global workshops and hundreds of comments from energy regulators from around the world. It identifies, organizes, and offers question and priority sets for key issue areas that fall within energy regulators' purview.

The paper includes two sets of policy recommendations: tools to boost hydrogen's uptake in high-value uses, and measures to minimize risks of H2's low-value uses. This thread is too long already, so I'll cover these another time. For now, read them here:

Key Finding 6: Hydrogen's uptake in high-value uses will require targeted demand-side policies. Supply-side subsidies alone will not ensure this outcome (and may make better alternatives for low-value uses look worse). Policymakers need to intervene.

Key Finding 5: In the U.S., hydrogen's market potential for high-value uses exceeds clean H2 production goals--so any H2 flowing to low-value uses cuts into decarbonizing high-value sectors on the needed timeline. (Efficiency, biofuels can help cut H2 demand in high-value uses.)

Key Finding 4 (cont.): This figure shows using clean electricity to displace fossil fuel power almost always does more to reduce GHGs than using it to electrolyze H2 for use in any downstream application. H2 is important, but it must not reverse progress on cleaning the grid.

Key Finding 4 (cont.): This figure shows the net climate pollution impact from hydrogen production and use. Blue bars = GHGs avoided from H2 use. Turquoise dashed line = GHGs emitted from electrolytic H2 production that fails to meet certain guardrails (the "three pillars").
