Hydrogen-Enhanced Biomethane for Energy System Resilience
Abstract
Biomethane from Anaerobic Digestion is currently injected into Gas Distribution Networks as a renewable alternative to fossil-fuel based natural gas.
AD plants currently supply largely constant flows, whilst gas demand fluctuates daily and seasonally, creating supply-demand imbalances which increase system balancing requirements.
Flexible, locally produced biomethane could help GDNs manage system balance by increasing injection during demand peaks or cold spells.
This project will use biomethanisation, injecting hydrogen to convert additional CO₂ within digesters, to boost biomethane output dynamically, supporting network balancing and Net-Zero ambitions.
Operational and regulatory frameworks will also be assessed to enable wider adoption of dynamic injection.
