Greening gas by valorizing CO₂ and waste

Gas, this other key element of our energy consumption.

Collectively, we are significant consumers of gas. By 2050, gas is expected to remain the world’s second-largest energy source, behind and complementing electricity. Previously reserved for heat production, gas is now used as fuel for transport (maritime, road) and to produce electricity. It is also a raw material for industry.

Gas, an energy source that needs to be greened.

The gas we consume remains largely fossil. Its extraction and combustion contribute to human greenhouse gas emissions, and thus to global warming.
But this can be avoided.
While CO₂ and non-reusable waste cannot be completely eliminated, we can recycle them into sustainable gases, substitutable for fossil gases for all our needs

Our solutions

We provide systems (equipment and biological cultures) that enable the recycling of CO₂ and waste into sustainable gases, such as synthetic methane and hydrogen.

Our systems tackle societal challenges by contributing to carbon neutrality

Capturing 3 tons of CO₂ for every ton of synthetic methane produced, thereby offsetting the CO₂ emissions from its combustion,

they also help valorize non-reusable waste, including sludge, end-of-life wood, plastics, and solid recovered fuels.

Acting as bridges between electrical and gas networks through a ‘Power-to-Gas’ architecture, our systems aid in storing excess electricity alongside other solutions like batteries.

Following a circular economy approach, they facilitate the production of gas at a more competitive price.

Our applications

Convert CO₂ and enrich biogas

Process syngas from our waste

Process industrial effluents (CO₂, H₂)

Store
electricity

Our technology

Over the past five years, in collaboration with our R&D partners, we have developed innovative technology and expertise, particularly centered on the biomethanation process. We co-own this technology and hold exclusive rights for its application in our projects.

Methanation involves producing methane from CO₂ or carbon monoxide and hydrogen.

Our technology, designed from consortia of microorganisms, is flexible (capable of treating various gases), robust (resistant to impurities), efficient (optimized energy consumption), and sustainable (non-pathogenic microorganisms and no use of rare natural resources).

Our projects

Our clients include renewable energy producers (gas and electricity), operators of waste recovery sites, and the constructors of these facilities. While we continue our industrialization program, we have launched several projects with many of them.

Our equipment

Denobio: the first industrial-scale biomethanation facility integrated with an agricultural methanation unit, featuring network injection. See the datasheet
Bimotep: design and operation of a mobile biomethanation unit for conducting tests on gas production sites (CO₂, biogas, syngas). See the datasheet
Demetha: design and operation of a pre-industrial biomethanation prototype coupled with a territorial methanation unit (project supported by the Occitanie Region). See the datasheet
Plainenergie: The first project in Europe that brings together local authorities, public laboratories, and industries to convert unvalued territorial waste into gas that can be injected into the natural gas network, by combining gasification and biomethanation.

About us

ENOSIS means ‘union’ in Greek. Because we believe that the success of the ecological transition relies on a systemic approach rooted in the heart of territories by creating bridges: between waste and energy, between electrical and gas networks, between CO₂ and sustainable gases, between biology and industry.

Based in Toulouse, the company was founded at the end of 2014 by Vincent Guerré, later joined by Stéphane Palmade. The team now has 11 collaborators, engineers and/or doctors.

In 2018, the European fund KIC InnoEnergy became a shareholder of ENOSIS. The company has a strategic committee, involving representatives of the shareholders and sector experts followed in 2022 by UI investissement, Industrya and the “Banque des Territoires”.
