The first large-scale biomethane production plant in Spain, using waste from a controlled waste repository, is expected to prevent the emission of 17,000 tonnes of CO₂ a year.
The Naturgy group gas distributor, Nedgia, will inject biomethane through its grid with a 6-kilometre pipeline constructed as part of the project.
Located in the PreZero Spain Controlled Waste Repository in Els Hostalets de Pierola, the facility was inaugurated by Regional Minister for Climate Action, Food and the Rural Agenda, David Mascort, along with authorities and business representatives, on 23 October.
It is the largest biomethane injection project using biogas generated from water from a controlled waste repository, and is the first financed by a long-term private power purchase agreement.
Thanks to the WAGABOX® technology patented by Waga Energy, 70 GWh of renewable gas will be injected annually into Nedgia’s grid, equivalent to the consumption of 14,000 households or 200 buses.
The initiative has obtained a grant of €2.4 million from the European Union through funds allocated for the development of innovative technologies to reduce carbon footprint.
According to Nedgia CEO Raúl Suárez: “This pioneering project puts gas networks and biomethane at the centre of the energy transition, to make it economically, socially and environmentally sustainable. Moreover, as it is a key local project, we can produce Km 0 gas, reducing imports and dependence on third countries”.
