Hydrogen and Biomass‐Based Hybrid Energy Storage Systems Converted Into Battery‐Dominant Energy Architectures for Grid Integration and Transportation Electrification

This perspective reframes hydrogen‐ and biomass‐based hybrid energy storage as a battery‐dominant architecture for grid integration and transportation electrification. The proposed system integrates biomass gasification or pyrolysis, renewable hydrogen production, compressed hydrogen storage, a battery energy storage system, power conversion equipment, and a supervisory energy management system. Its central argument is that batteries should act as the primary fast‐response stabiliser, while hydrogen and biomass supply long‐duration storage, dispatchable fuel and resilience during periods of renewable scarcity. Synthesising recent literature on hydrogen storage, biomass‐to‐hydrogen conversion, battery energy storage, electric‐vehicle charging and multi‐timescale energy management, the analysis uses scenario‐based figures to show how a hybrid hydrogen‐biomass‐battery system can reduce frequency deviation, smooth daily renewable dispatch and lower annual carbon emissions relative to fossil‐dominated and renewable‐battery‐only baselines. Hybridisation proves technically strongest when each storage technology is assigned to its natural time scale: batteries for milliseconds to hours, hydrogen for hours to seasons, and biomass as a dispatchable renewable feedstock. Successful deployment, in turn, depends on degradation‐aware control, cost‐optimised electrolysis operation, sustainable biomass sourcing, safety‐compliant hydrogen infrastructure, standardised power electronics, and carbon accounting that distinguishes renewable, biomass‐derived and grid‐connected hydrogen production.
