EnergyPathways rises 5% as MESH energy storage project advances to detailed engineering

EnergyPathways PLC (AIM:EPP), the energy transition company, rose 5% to 6.48p after announcing that engineering contractor Costain has shortlisted onshore facility sites for its MESH long-duration energy storage project in Barrow-in-Furness.

Costain, the FTSE-listed engineering group, completed a first phase of site assessment before selecting locations for further evaluation and front-end engineering and design, with detailed second-phase engineering now underway.

MESH, designated a project of national significance by the UK Department for Energy Security and Net Zero in September 2025, is planned as an integrated storage scheme in the east Irish Sea combining compressed air, natural gas and hydrogen storage in offshore salt caverns with flexible medium-range gas field storage.

The project would connect to Britain's energy network through new and existing pipelines and transmission lines.

EnergyPathways said it intends to develop a sustainable industry park at Barrow-in-Furness, incorporating hydrogen and graphite production, clean ammonia production, an energy storage operations base, and connection and export infrastructure.

Chief executive Ben Clube said Costain had provided a strong foundation of front-end engineering design and identified a number of quality sites for the onshore facilities.
