This report by RMI provides a strategic framework for hydrogen project developers to comply with the proposed 45V clean hydrogen production tax credit in the United States. It details the 'four pillars' of the Treasury's proposed guidance—regionality, hourly matching, incrementality, and attribute tradeability—and outlines an ecosystem of registries, contracts, and operational strategies needed to secure the highest credit tier of $3 per kg of hydrogen.

This oral testimony from Energy Innovation to the U.S. Treasury Department and Internal Revenue Service argues for the retention of strict "three pillars" (incrementality, deliverability, and hourly time-matching) for the 45V Clean Hydrogen Production Tax Credit. The author contends that weakening these rules would lead to significant greenhouse gas emissions, undermine the long-term viability of the hydrogen industry, and result in the misuse of taxpayer funds.

This policy brief by RMI outlines how U.S. states can utilize Low-Carbon Fuel Standards (LCFS) to incentivize the adoption of clean hydrogen and hydrogen-derived fuels, particularly for hard-to-abate sectors like aviation, maritime shipping, and long-haul trucking. It analyzes existing programs in California, Oregon, and Washington to provide four key lessons for future state policies to ensure clean hydrogen is directed toward high-priority uses rather than sectors where electrification is more efficient.

This report by RMI provides guidance and best practices for developers participating in the US Department of Energy's (DOE) $7 billion Regional Clean Hydrogen Hubs (H2Hubs) program. It focuses on the necessity of meaningful, two-way community engagement and the implementation of Community Benefits Plans (CBPs) to ensure an equitable energy transition, particularly for disadvantaged communities.

This appendix provides a financial viability analysis of 'export-only' electrolyzer projects in the United States, which utilize co-located new clean energy resources and allow for opportunistic electricity sales to the grid. The analysis concludes that such projects, which comply with the three principles of additionality, deliverability, and hourly time-matching, are competitive across large portions of the U.S., suggesting that rigorous 45V tax credit guidance regarding lifecycle greenhouse gas emissions would not hinder industry growth.

This RMI insight brief examines the policy landscapes for clean hydrogen-based steelmaking in China and Europe, analyzing the potential for hydrogen-based steel in China and offering policy recommendations to support the transition to zero-carbon steelmaking.

This guide from Energy Innovation provides a blueprint for U.S. state policymakers to stimulate investments in clean industries, particularly in response to the negative economic impacts of the One Big Beautiful Bill Act (OBBBA). It outlines strategies to attract clean industrial projects, overcome regulatory and commercial barriers, and leverage technologies like industrial thermal batteries and low-carbon hydrogen to decarbonize manufacturing.

This research paper examines the potential for clean hydrogen to decarbonize the United States freight transport sector, including road, air, water, and rail. It positions hydrogen as a complementary solution to electrification and other clean fuels, noting that while significant cost, infrastructure, and technological barriers exist, hydrogen and hydrogen-based fuels could provide mature, low-carbon alternatives by 2050.
