EnergyPathways, the energy transition company, is pleased to announce that it has given notice to and received consent from the North Sea Transition Authority (“NSTA”) to apply for new hydrogen and natural gas storage licences in the East Irish Sea in support of its flagship MESH project (“MESH” or the “Project”).

The Company expects to submit one or more new Gas Storage applications later this month to support its expansion plans for the MESH project – a large-scale long duration energy storage (“LDES”) and decarbonisation project. The Company’s nominated area for these new hydrogen and natural gas storage licences covers an area of salt cavern storage potential
around four times greater than it had previously applied for.

This strategic step follows the direction issued on 26 September 2025 by the Rt Hon, Ed Miliband, the UK’s Secretary of State for Energy Security and Net Zero, confirming that that key elements of the Company’s integrated MESH development should be treated as a development of national significance under the 2008 Planning Act, underscoring its potential critical role in the
country’s long-term energy security and net zero strategy and the supply of more affordable energy to British consumers.

The Company’s applications, if successful, will provide opportunity for expanded salt cavern energy storage capacity and the significant scalable expansion of the MESH project as a major integrated LDES and low-carbon flexible power system, further underpinning EnergyPathways’ vision to grow the Project into one of the UK’s largest integrated energy storage and
decarbonisation hubs.

Ben Clube, Chief Executive Officer of EnergyPathways, commented:
“We are delighted to advance our plans to apply for new hydrogen and natural gas storage licences from the NSTA.
“This follows the Secretary of State’s formal confirmation that our MESH project is a project of national significance – a powerful signal that reinforces our confidence in the UK investment environment for energy transition projects such as MESH. It further highlights MESH’s potential to supply more affordable energy to Britain’s consumers and make a material contribution to the
nation’s Clean Power 2030, energy security, and net zero ambitions.

“By developing MESH for large scale LDES, low-carbon flexible power and new hydrogen production industries, MESH is firmly aligned with the government’s energy priorities. We are now accelerating project delivery alongside our Tier 1 partners, including Siemens Energy, Hazer Group in conjunction with KBR Inc., Wood plc, Costain plc, and Zenith Energy. In parallel we will progress our applications for the consents and approvals required to bring this landmark project into operation.

“If the Company is successful with these new hydrogen and natural gas storage licence applications, EnergyPathways will secure an area of salt cavern storage potential around four times greater than that it had previously sought. MESH would represent a scalable business model and growth platform for EnergyPathways that will have potential to become a key
component in the decarbonised energy future of the UK.”
