Our renewable gas projects
Storengy and its partners – achievements and recent projects
It is the first Power-to-Gas project in France that combines:
- methanisation (production of biomethane)
- electrolysis (production of hydrogen)
- methanation (production of synthetic methane)
Led by Storengy and located at Céré-la-Ronde in the Centre-Val de Loire region of central France, it provides a solution for a crucial challenge: transforming renewable electricity (and the CO2 contained in the biogas) into large quantities of hydrogen and synthetic methane in order to meet our customers’ needs, whether for green mobility powered by hydrogen and biogas (bio-CNG) or for injection into the natural gas network. The financing plan for this project has been completed. It is funded by the “Investing in the Future” (PIA) programme operated by ADEME (the French Environment and Energy Management Agency), the Centre-Val de Loire region and the European Regional Development Fund (ERDF).
Implementation date: 2020-2021
The first commercial project of this scale in France, HyGreen Provence is based on the construction of a system for the local production of renewable electricity, valorised in the form of hydrogen, itself potentially stored in salt caverns on a site operated by Storengy. The final objective is to supply a network of green mobility stations deployed in the region as well as industries. Storengy's know-how, infrastructure and R&D work on the production and storage of hydrogen above or below ground are key to the success of such a project.
The Hycaunais project (Burgundy Franche Comté Region)
This is a territorial project for the production and storage of renewable energy.
This Power-to-Gas demonstrator will make it possible to:
- transform renewable electricity from a wind farm
- recover CO2 from a non-hazardous waste storage facility (ISDN) in the area
- produce renewable hydrogen and e-methane
*Power-to-Gas enables electricity from renewable energy sources to be converted into gas which is renewable as well. It involves using electricity from renewable resources (such as wind power for Hycaunais) to generate gas that can be stored. This is made possible by the combination of the two processes used: electrolysis and methanation.
The project players and their role:
- Storengy: project leader for all the partners and integrator
- Electrochaea: supplier of the biological methanation technology
- Elogen: supplier of the electrolyser
- ENGIE Green: implementation of the renewable energy production software
- ENGIE Lab Crigen: project integrator
- Syndicat Départemental d'Energies de l'Yonne (SDEY): project integrator
- SEM Yonne Energie: project integrator
- University of Franche Comté (UFC): validation of the technical and economic approach of the project for its replicability
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:
- A zero-carbon target by 2025
- A reduction of 30 tonnes of C02 emissions per year
- 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 £345,000 contribution from the Local Growth Fund.
In the region of Auvergne Rhône Alpes, Storengy and its partners (Axelera, Armines-Ecole polytechnique, Element Energy, ESK, Ineris, Inovyn) 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 1,760 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 1,000 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 been granted financing by the Fuel Celles and Hydrogen Joint Undertaking (FCH 2 JU) under the subvention agreement no. 101006751. This public-private partnership has received the support of the Horizon 2020 research and innovation programme by the European Union, Hydrogen Europe and Hydrogen Europe Research.
H2bordeaux project (Region of Nouvelle Aquitaine)
With its partners Grand Port de Bordeaux and Nexeya, Storengy is developing this project which will facilitate the development of the hydrogen sector in the region of Bordeaux:
- to create a circular economy by recovering non-used hydrogen (3,000 tons from a local industry, Nouryon)
- to improve the carbon footprint of transportation and industry in the region
- to create an innovative, high-performance, replicable hydrogen sector
The studies led since September 2020 aim to:
- get to know the potential of hydrogen consumption in the port of Bordeaux for mobility (land or river) or stationary applications
- support the development of the hydrogen sector and solution suppliers
- create a reference project which may be used to duplicate similar projects to other port areas
- bring forward the conversion and manufacturing of hydrogen vehicles
This project has been granted co-financing by the European Union at 50% of the overall costs of the studies, which amount to 750 k€.
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.
