Instanz: TeilenTeilen:New Study: How Carbon Accounting Rules Shape Incentives for Hydrogen ProductionYvonne Kaul Abteilung KommunikationUniversität Mannheim10.08.2026 12:11A new study by University of Mannheim researchers Gunther Glenk, Philip Holler, and Stefan Reichelstein examines how the assessment of carbon emissions affects the incentives for the production of electrolytic hydrogen. Its key finding: even stringent accounting rules generally provide sufficient investment incentives. There is currently a policy debate over which carbon accounting rules are appropriate: Should the renewable electricity used for electrolysis be matched on an hourly basis, or is annual accounting sufficient? “Strict carbon accounting rules lead to significantly lower-emission hydrogen production and are likely to provide sufficient investment incentives, particularly in regions with abundant renewable resources.” How Carbon Accounting Rules Shape Incentives for Hydrogen Production.
