Generating and storing biomethane

With our ENGIE Biogas branch, we are France’s number one biomethane producer.

storengy - Generating and storing biomethane

ENGIE Biogas purchased Vol-V Biomasse in February 2019.

Created in 2009 and based in Rennes and Rouen in western France, the company is involved in each step of the biomethane value chain from development via monitoring of construction to operation.

Today, Vol-V Biomasse is structured as follows:

  • 9 operating units,
  • 3 units under construction,
  • 1 portfolio with approximatively 20 projects.

Through this acquisition, we, together with ENGIE Biogas, are strengthening our leading position on the biomethane market.

Storengy is involved in the production and storage of biomethane. Find out about some of our projects.

Infrastructure and production

We are developing five major methanisation projects close to our French sites.

We have the following goals:

  • to foster the development of renewable energies in the areas where we operate,
  • to use the local network,
  • to make the most of links with farmers.

ENGIE Biogas is contributing to these projects by sharing all its biogas expertise, while Storengy is providing project management support in both the study phase and in project construction and management.

Innovation and development

Azola is a startup incubated by Storengy that is developing a liquid biomethane storage solution that allows producers to increase recovery by 10%.

R&D for “leverage” solutions

“Leverage” solutions are solutions that increase biogas recovery. The MéthyCentre project, for instance, uses this type of solution by combining methanisation with a Power-to-Gas unit. Operation:
Methanisation produces carbon dioxide (CO2) which, instead of being emitted into the atmosphere, is used directly in the Power-to-Gas process which itself uses CO2 and hydrogen to produce synthetic methane.Thus, all of the carbon dioxide is recovered. This is clearly a “leverage” solution.
