EnergyPathways to Submit New Hydrogen and Natural Gas Storage Licence
Applications for the MESH Project

 

EnergyPathways (AIM: EPP), 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."

 

About MESH

 

MESH will be a new, large scale, energy storage and decarbonisation facility
that is expected to provide a secure and dependable supply of affordable
low-carbon energy for the UK market for over 25 years.

 

The MESH integrated energy system solution comprises; large-scale Long
Duration Energy Storage ("LDES"), flexible low-carbon power capacity and
low-carbon hydrogen and graphite production with the potential to branch into
low-carbon ammonia production. MESH will connect its LDES integrated storage
system using existing infrastructure to the UK grid and nearby offshore wind
capacity to help harness value from some of the billions of pounds of the UK's
wasted wind power.

 

The MESH system is designed to capture and store curtailed offshore wind power
in offshore salt caverns as compressed air. The MESH energy storage system
combines associated large-scale hydrogen, thermal and natural gas storage
capacity in salt caverns, as well as gas storage in the Marram gas field
clastic reservoirs. During periods of low renewable energy availability, the
LDES stored energy resources will be utilised to generate low-carbon flexible
power for the UK's grid via compressed air expansion, thermal energy and
hydrogen-compatible gas turbine systems to generate electricity. This
integrated system will provide affordable low-carbon dispatchable electricity
to the UK grid, enhancing its energy security and flexibility.

 

The MESH facility will also produce affordable low-carbon hydrogen using a
methane pyrolysis technology to which EnergyPathways has exclusive rights of
use within the UK. The hydrogen can be used to further decarbonise the MESH
flexible power generation system using its hydrogen compatible gas turbine
system. The hydrogen produced can also be stored in MESH hydrogen storage or
supply hydrogen into the UK's emerging Project Union hydrogen network, further
contributing to emissions reduction across the broader UK energy system. MESH
hydrogen also has potential to be used to produce low-carbon ammonia at
bolt-on facilities. The by-product of the MESH hydrogen production facility
will be a high-grade form of synthetic graphite, a critical mineral for energy
transition.

 

The MESH project is targeted to be operational by 2030, subject to government
approvals and financing, in order to contribute to the Government's 2030 Clean
Power ambitions. EnergyPathways aims to play its role in supporting the
Government in accelerating the UK's energy transition.
