The use of greener gases such as biomethane are an important part of the UK's transition to net zero. Underground storage sites for biomethane are critical for balancing seasonal supply and demands for energy. However, increased levels of oxygen in biomethane can lead to corrosion of assets in wet gas conditions, compromising the integrity of storage facilities. This project will assess in a comparative analysis the technical and economic viability of advanced catalytic and adsorption technologies to reduce oxygen levels in biomethane with corrosion inhibitors to ensure the integrity and longevity of critical storage infrastructure.

Linepack flexibility is key for Gas Transmission to provide system resilience by management of swings within operational limits. In a hydrogen world, we know our energy content per km of linepack will decrease by up to 76%. Therefore, embedded resilience systems in the form of lined rock shafts are being investigated to supplement loss in linepack capability. We envision systems if implemented for hydrogen transmission to act similar to how now decommissioned natural gas holders were utilised for operational flexibility, pressure regulation, supply/demand mismatch management, load balancing, emergency backup and production buffering.
