Major bio-LNG project inaugurated in France

BioNGVAL is the name of a major French liquefied biomethane (bio-LNG) demonstration plant that was officially inaugurated today.

Launched in February 2013 with the support of the French Environment and Energy Management Agency (ADEME) under its “Investissements for the Future” programme, the Valenton (Val-de-Marne region) wastewater treatment plant (WWTP) was selected as the site for the BioGNVAL project.

Treating 800 000 m3 of water per day SIAAP’s (Syndicat Interdépartemental pour l’Assainissement de l’Agglomération Parisienne  – Paris regional wastewater authority) Valerton is one of the largest WWTP’s in Europe.

Successful demonstration

Under the coordination of SUEZ along with several partners including SIAAP, Cyro Pur, Iveco and Thermo King together with GNVert and LNGeneration, the latter two wholly owned subsidiaries of ENGIE that supply and distributes liquefied natural gas (LNG) to industrial and commercial end-users, the project aimed to demonstrate the technical and economic feasibility of producing liquid biomethane from biogas, with a view to developing the process on an international scale.

The BioGNVAL project has now demonstrated that it can from the wastewater sludge, produce a clean fuel that does not emit any fine particles, make 50 percent less noise and cuts CO2 emissions by 90 percent compared with a diesel engine. The BioGNVAL industrial demonstrator can treat almost 120 Nm3 per hour of biogas, to produce one tonne per day of bio-LNG, or two full tanks for a heavy goods vehicle (HGV).

Bio-LNG adds flexibility

According to ENGIE, 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 power generation at off-grid sites.

As a specialist in the distribution of alternative fuels, GNVert’s role in the project is to convert the liquefied biomethane produced at the site into a transportation biofuel. In particular, GNVert has conducted tests using bio-LNG to power LNG engines. The tests were performed in

The tests were performed in Valde-Marne at its Rungis LNG/CLNG (compressed liquefied natural gas) filling station, the first of three GNVert liquefied natural gas filling stations built within the framework of the European LNG “Blue Corridors3” project.

LNGeneration is positioned downstream in the BioGNVAL project; its role is to recover the liquefied biomethane produced. Industrial demonstrations of bio-LNG supply are already scheduled for a number of industrial sites in 2016.
