EnergyPathways (AIM: EPP) has appointed Zenith Energy Ltd. as its well engineering partner for the MESH project—a groundbreaking initiative that will combine green hydrogen, natural gas, and compressed air energy storage into one of the UK’s largest integrated energy storage facilities. Designed to support the country’s energy transition, MESH aims to deliver clean, flexible, and secure power while accelerating the deployment of green hydrogen technologies.
The MESH development, located in the East Irish Sea region, will integrate existing offshore infrastructure with electrified systems powered by UK wind farms. The project is expected to store up to 20 terawatt-hours (TWh) of energy and support the government’s 2030 Clean Power targets, while delivering low-carbon solutions for domestic energy security. A key component of MESH will be its capacity for long-duration green hydrogen storage, allowing for seamless integration of intermittent renewables into the national grid.
To advance the project, EnergyPathways has engaged Zenith Energy, one of the UK’s largest independent well engineering and project management firms, to serve as Well Operator for its subsidiary EnergyPathways Irish Sea Limited (EPISL). Zenith will oversee the full scope of well engineering services—including drilling and completion design, permit planning, tendering and procurement, rig intake, and final execution of the Marram development wells.
Derek Grimmer, Chief Operating Officer of EnergyPathways, commented:
“Zenith is the ideal partner for our MESH project, not just for their drilling expertise but also for their ability to support green hydrogen and long-duration energy storage operations. Their deep collaboration during the pre-FEED phase has demonstrated the value they bring. Our contractor-led model allows us to stay efficient while aligning with top-tier partners as we deliver a fully decarbonised and electrified energy system.”
Chris Collie, Operations Director at Zenith Energy, added:
“We are proud to support EnergyPathways on a project of such national importance. MESH not only strengthens the UK’s energy resilience, but also sets a new standard for integrated green hydrogen and energy storage solutions. This partnership aligns perfectly with our mission to contribute meaningfully to the UK’s Net Zero future.”
About the MESH Project
MESH (Multi-Energy Storage Hub) is a next-generation, fully integrated energy project that will combine natural gas, compressed air, and green hydrogen storage—all powered by renewable energy from UK offshore wind farms. It is being developed by EnergyPathways to provide secure, flexible, and decarbonised energy to the UK for more than 25 years.
By linking legacy gas infrastructure with cutting-edge green hydrogen and energy storage technologies, MESH is designed to be a zero-emissions facility. It will play a central role in meeting future energy demands while reducing reliance on fossil fuels and strengthening the UK’s energy independence.
As part of a wider strategy to enable long-duration energy storage, MESH also positions EnergyPathways as a key player in helping the UK reach its clean energy and decarbonisation goals.
