Our hydrogen projects

HyPSTER

In the region of Auvergne Rhône Alpes, Storengy and its partners (Axelera, Armines-Ecole polytechnique, Element Energy, ESK, Ineris, Inovyn, Equinor, Brouard Consulting) develop the first demonstrator of large-scale green hydrogen storage.

This project is going to use a salt cavern of the Storengy storage site in Etrez to connect electrolysis production to industrial and mobility applications.

The salt cavern used has a storage capacity of  44 tons of hydrogen, which is the equivalent of 1760 hydrogen bus tanks.

HyPSTER is located in a particularly dynamic territory regarding the development of green hydrogen usages with large-scale projects such as Zero Emission Valley (Project ZEV) in the region of Auvergne-Rhône-Alpes, the construction of hydrogen production units and filling stations in the region of Bourgogne Franche Comté. Its geographical location is also an asset for industries which are present in the Chemical Valley.

The ZEV (Zero Emission Valley) project in the region of Auvergne Rhône Alpes comprises 20 hydrogen stations and 1000 hydrogen vehicles by 2023. Industrial grey hydrogen applications are already existing (especially in the Chemical Valley) and decarbonising the industry and heavy mobility of this sector with green hydrogen is being taken into consideration.

This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (now Clean Hydrogen Partnership) under Grant Agreement No 101006751. This Joint Undertaking receives support from the European Union’s Horizon 2020 Research and Innovation programme, Hydrogen Europe and Hydrogen Europe Research.

MéthyCentre

The first innovative Power-to-Gas demonstrator coupled with agricultural methanisation.

The process combines the use of a 250 KW electrolyser and an agricultural methanisation unit.

MéthyCentre's objective is to demonstrate the technological and economic feasibility of the process, which makes it possible to obtain three decarbonized gases:

• renewable hydrogen
• biomethane
• synthetic methane

In 2023, MéthyCentre will produce 50 m³/h of green gas and 50 kg of hydrogen per day.

90% of the hydrogen produced will be used to produce synthetic methane for injection into the GRDF distribution network for traditional residential and industrial uses. The remaining 10% of the hydrogen will be used for green mobility and to power the mobility terminal installed on the site.

During 2 years, the pilot will follow an experimentation program in order to test the intermittent operation and to measure the performance of the technological bricks.

This project is supported by the France 2030 Investment Programme operated by ADEME, the Centre-Val de Loire Region via its ERDF funds and co-constructed with our partners: CEA, Elogen, Khimod, Prodeval, La Sablière and the Syndicat intercommunal d'énergie d'Indre-et-Loire (SIEIL).

Hydrogen storage project at Manosque

The Géométhane storage site at Manosque, operated by Storengy, has 9 salt caverns, including 7 natural gas caverns. The total geometric volume of caverns in service is 2.7 Mm3, compared with the 6 Mm3 authorised by the concession. In addition to the 7 caverns in operation, there are two caverns available that are technically and administratively suitable for storing hydrogen.

The issues of security of supply for industry and compatibility with European directives on the development of renewable energies (RED II, and soon RED III) highlight the urgent need for massive storage (several thousand tonnes) for the Fos-Marseille carbon-free hydrogen consumption basin.

The Manosque salt caverns represent a strategic asset in this respect since they will enable around 6,000 tonnes of hydrogen to be stored. It is also possible to continue leaching existing caverns to increase capacity and create new caverns to meet changing needs.

Storage in salt caverns offers great flexibility and can respond very quickly to any demand. The quantity of gas contained in the pipeline between Manosque and the Marseille - Fos-sur-Mer Basin provides additional flexibility. Switching from injection to withdrawal mode or vice versa can be done in a short space of time, and injection and withdrawal flow rates can be very high.

Salt caverns provide security of supply, make it possible to adjust hydrogen production and consumption curves, manage the intermittent nature of renewable energies and provide tools for flexibility and optimisation of electricity grids.

ETI (UK)

As part of an Energy Technology Institute (ETI) funded study on energy storage, Storengy's expertise was used to provide detailed geoscientific information. The results of the study confirmed that hydrogen storage in salt caverns is a credible technology with the salt strata used in the natural gas storage facilities at Storengy's UK site in Cheshire. Moreover, it is one of the most cost-effective solutions. Storengy is currently working on hydrogen storage with an electrolyser manufacturer to study the feasibility of a 100 MW electrolysis project (Centurion Project).

Vanguard green hydrogen project (UK)

Storengy is responsible for the installation of the refuelling station, its operation and the marketing and sale of the green transport fuel certificates.

The project will see the first green station in the North West of the UK with the production of green hydrogen fuel to enable three vehicles, including two refuse trucks, to run on the technology.

The hydrogen will be produced by installing solar panels which will convert the energy via an electrolyser to produce the green fuel.

The project meets emission reduction targets, including:

1. A zero carbon target by 2025
2. A reduction of 30 tonnes of CO₂ emissions per year
3. A reduction in diesel use of 10.000 litres per year

The station will eventually supply Cheshire County Council’s refuse trucks and Storengy UK vehicles.

The project has been funded by public and private funds - with a £345000 contribution from the Local Growth Fund.

Centurion (UK)

As a partner in the Centurion project supported by Innovate UK, Storengy is embarking, alongside  ITM Power, Inovyn, Cadent and Element Energy , on the first stage of an innovation project that aims to deploy an electrolyser with a capacity of 100 MW combining the transport and storage of hydrogen.

The objective is to produce low-carbon hydrogen for industrial, mobility and heating uses.

This first phase consists of a feasibility study to demonstrate the interest of Power-to-Gas to decarbonise the energy system by achieving significant cost reductions. This project could be the largest energy storage system at the interface between the gas and electricity networks in the world. The feasibility study is co-funded by Innovate UK.
