The European ECO-GATE Consortium, co-financed by the European Union and led by Nedgia, the gas distributor of the Naturgy group, has initiated test injection and distribution of the renewable gas generated at the Butarque wastewater treatment plant (WWTP) in the Nedgia distribution network. Butarque’s renewable gas project has the collaboration of Enagás, Canal de Isabel II, Naturgy and the Community of Madrid.
This is a milestone in the distribution of natural gas in Spain, since it will be the first time that renewable gas has been injected into the distribution network that will serve to develop the system of certificates of origin for renewable gas in Spain to advance in the compliance with the environmental decarbonization objectives proposed by Europe in 2030.
With the development of this innovative project at the WWTP in Butarque, the European ECO-GATE consortium has four objectives:
- The production of biomethane from a biogas generated from waste recovery.
- The injection of biomethane produced into the natural gas distribution network owned by NEDGIA, for distribution to the point of final consumption.
- Market development of certificates of origin of renewable gas in Spain.
- Demonstration of efficient and ecological use of renewable gas in land mobility applications.
Same applications as natural gas
Biomethane, as a renewable gas, is a CO2 emissions-neutral fuel generated through the degradation processes of organic matter. In this way, urban, agricultural, livestock and forest waste, wastewater, etc. are treated and transformed into a green gas, an energy that is completely interchangeable with natural gas, so it can be distributed through the most of 87,000 km of the gas infrastructure that exists in Spain and used with the same energy applications in homes, industries, and shops, as well as for fuel in the transport sector. This does not require investments (neither public nor private) to be made to transform network infrastructures or user consumption equipment.
