The 'Hydrogen Criteria' document, published by the Climate Bonds Initiative in August 2023, establishes a draft framework for certifying hydrogen-related assets, projects, and entities. It defines eligibility for Use-of-Proceeds (UoP) bonds, Sustainability-Linked Bonds (SLBs), and entity certifications across the hydrogen value chain, including production, conditioning, transportation, and storage. The criteria focus on strict greenhouse gas (GHG) emissions intensity thresholds, mandatory adaptation and resilience assessments, and specific technical requirements for different production pathways.

RMI provides recommendations for the US Department of the Treasury regarding the 45V production tax credit (PTC) for grid-connected green hydrogen, arguing for a balance between industry acceleration and strict emissions standards to ensure climate goals are met.

The Southeast Asian Working Group on Fossil Gas and Energy Transition criticizes Vietnam's eighth power development plan (PDP8), arguing that it preserves a reliance on fossil fuels and sets unambitious renewable energy targets despite the country's potential for clean energy leadership.

This guide by RMI outlines three primary federal funding mechanisms available for clean industrial projects in the United States: grants from the Office of Clean Energy Demonstration (OCED), loans from the Loan Programs Office (LPO), and tax credits administered by the Department of the Treasury under the Inflation Reduction Act (IRA).

This briefing by Zero Carbon Analytics argues that natural gas is a primary driver of the climate crisis and must be rapidly phased down to limit global warming to 1.5°C. The document contends that gas is as harmful as coal due to methane leakage and the energy intensity of LNG, and that expanding gas infrastructure in response to energy crises creates stranded asset risks and harms public health. It further dismisses the industry claim that gas infrastructure can be cost-effectively converted to hydrogen.

The Europe Gas Tracker Report 2023 by Global Energy Monitor analyzes the rapid expansion of gas infrastructure in the European Union following the Russian invasion of Ukraine. The report argues that a 'gas panic' has led to uncoordinated buildouts of LNG terminals and pipelines that risk creating massive overcapacity and locking the region into fossil fuel dependency, potentially undermining the EU's climate goals under the European Climate Law and the Fit for 55 package.

This policy brief by RMI discusses the potential of a new US tax credit for low-emission hydrogen production, established via the Inflation Reduction Act, to catalyze the clean hydrogen economy and industrial decarbonization. The document argues that the US Treasury's implementation of the credit—specifically regarding standards for grid-connected electrolyzers—will determine whether the incentive drives genuine emissions reductions or inadvertently increases greenhouse gas emissions.

This report by the NewClimate Institute examines the role of hydrogen in achieving 1.5 degrees of global warming and identifies four primary investment opportunities for Latin America, specifically Argentina, Brazil, and Peru, to integrate into the global hydrogen economy.

This fact sheet from the Center for International Environmental Law argues that recent United States legislation, specifically the Infrastructure Investment and Jobs Act (IIJA) of 2021 and the Inflation Reduction Act (IRA) of 2022, provides excessive subsidies and regulatory support to the fossil fuel industry through carbon capture, hydrogen production, and federal land leasing.

This RMI fact sheet argues that hydrogen is not a significant warming risk and is a powerful tool for decarbonizing hard-to-electrify sectors. It asserts that hydrogen's warming potential is significantly lower than that of the natural gas it replaces, particularly when considering energy density. The document emphasizes that focusing deployment on industrial hubs and prioritizing green hydrogen can minimize leakage risks and maximize emissions reductions.

This document is a glossary accompanying a technical report titled "Escenario Ruta a Cero Neto 2050," developed by Transforma and WWF. It provides standardized definitions for energy and climate-related terms used in an indicative net-zero scenario for Colombia's energy sector by 2050.

This document provides detailed appendices for the proposed Estonian Hydrogen Roadmap 2021–2050. It outlines a phased transition toward a hydrogen economy, focusing on decarbonizing transport, industry, buildings, and the energy sector through the adoption of green hydrogen and fuel cell technologies.

This executive summary, published by the Stockholm Environment Institute in May 2021, analyzes the potential for hydrogen resource usage in Estonia between 2020 and 2050. It evaluates the hydrogen value chain—production, storage, distribution, and consumption—across the transport, industrial, building, and power sectors. The report identifies the transport and chemical industries as the primary areas for decarbonization and outlines the necessary investments, infrastructure, and policy measures required to transition to a hydrogen economy.

This working paper analyzes the demonstration phase of the HYBRIT project, which aims to decarbonize the steel industry using a hydrogen direct reduction (HD-R) process. The authors compare small-scale pilot plants with large-scale demonstration plants, concluding that larger plants are more effective for securing financing, permitting, and business models, despite higher regulatory risks.

This document is a feedback submission from the NGO Ember to the European Commission regarding the revision of guidelines for Trans-European energy infrastructure. Ember argues for a rapid shift away from fossil gas infrastructure, an increase in renewable energy sources (RES) and grid flexibility, and more transparent governance of infrastructure planning.

This research paper, co-authored by 30 experts following a 2018 Aspen Global Change Institute workshop, provides a blueprint for achieving net zero global industrial emissions by 2050–2070. It identifies key technical measures and policies required to decarbonize the industrial sector, which accounted for 33% of global anthropogenic emissions in 2014.

This report by Energy Innovation outlines an illustrative policy pathway to achieve net zero emissions in the United States by 2050 using the Energy Policy Simulator (EPS). The proposed pathway aims to abate over 6 Gt of emissions annually and save more than 120,000 lives per year by reducing particulate pollution, focusing on the industrial, transportation, electricity, and buildings sectors.

This briefing by RMI argues that hydrogen is a critical complement to electrification in the energy transition, particularly for hard-to-abate industrial sectors and heavy transport. It outlines the different production methods—distinguishing between grey, blue, and green hydrogen—and highlights the potential for green hydrogen to drive renewable energy demand and decarbonize industrial value chains.

This fact sheet provides an overview of fuel cell technology, detailing its operational mechanisms, various types, and its comparative advantages over internal combustion engines and batteries. It examines the technical and economic barriers to widespread adoption—specifically cost, hydrogen production, and infrastructure—while outlining current applications in portable, stationary, and transportation sectors. The document also analyzes the role of U.S. federal and state policies, including Department of Energy (DOE) initiatives and state-level incentives, in driving the commercialization and deployment of fuel cells.

Amory B. Lovins of the Rocky Mountain Institute (RMI) critiques the March 2004 American Physical Society (APS) report "The Hydrogen Initiative," arguing that it reaches erroneous conclusions regarding hydrogen economics and storage due to outdated assumptions and methodological flaws.
