About the VOL-V Group

In the 1990s, the founders of VOL-V, an independent producer of renewable energies, launched into wind power and then solar power, before pioneering biomethane in the 2010s. With the sale of these activities to the Engie group and CNR in 2019, they have naturally decided to put their 25 years of experience at the service of renewable energies to make VOL-V an accelerator and facilitator of the energy and ecological transition. VOL-V also aims to support cutting-edge technology companies, such as the Absolut Group, whose applications can have a decisive impact on the environment.

A 150 million € investment programme has been launched, a third of which has already been allocated to a dozen investments in unlisted French companies in the fields of hydrogen, sustainable agriculture, sobriety and low-carbon building. VOL-V focuses its efforts on French companies and positions itself as a reference shareholder, possibly with a majority stake, making available its resources and entrepreneurial experience.

The VOL-V Group’s role as an investor and coach enables it to help companies with cutting-edge expertise and strong industrial potential to scale up and develop tomorrow’s research in a fast-changing sector.
