Engie, a French energy supplier with a major focus on sustainable energy, through its wholly owned subsidiaries GNVert and LNGeneration is contributing to the development of a new “green gas” sector in France. Bio-LNG (Liquefied Biomethane) offers a cost-effective, eco-friendly fuel solution for the transport sector.

The SIAAP1 wastewater treatment plant in Valenton (Val-de-Marne region), is the site of a pilot project known as “BioGNVAL” involving several partners under the coordination of Suez. The first of its kind in France, the initiative uses the plant’s wastewater sludge generated by millions of Parisiennes to produce Bio-LNG and liquefied CO2. A 100% renewable energy source, Bio-LNG is bringing added flexibility to the use of biomethane: in addition to injection into the natural gas grid, significant new growth opportunities are opening up for green mobility and off-grid power generation.

Historically, natural gas has been the least expensive energy source. Savings generated by conversion to natural gas, either as a vehicle fuel or for power generation, can be on the order of 25% of an annual budget. In less than 6 months, Engie subsidiaries have the capacity to install LNG for any use (vehicle fuel, electricity generation, etc.). Finally, as fuel, natural gas (LNG, CNG – compressed natural gas) also cuts engine noise nearly in half. Bio-LNG has the added attractiveness of being a 100% renewable energy source.
