Renewable gas and the circular economy

Promoter Naturgy This renewable gas plant next to the Elena landfill in Parc de l’Alba represents a major milestone: it was the first to inject renewable gas from a landfill into the gas distribution network in Spain.   But that’s not all. It also represents a green energy project, will support the circular economy and is a clear reflection of our support for local energy production.   With this facility, we are demonstrating our capacity for success on this type of project based on the strength of our distribution network, which is ready to distribute renewable gases due to the investments made in recent years, the existing gas infrastructure in Spain and its contribution to supply security.  

• 15 Gwh/year, enough to supply 2,942 homes.
• Reduction of CO₂ emissions by 2,730 tonnes/year, equivalent to the planting of 295,135 trees.
• Biomethane from landfill waste.

Promoter BIOENGAS/ENAGAS   The UNUE project biogas plant, located on the Biogasnalia site, is the first plant in Spain to inject biomethane from agri-food waste. It receives up to 90 tonnes/day of waste from various food and agri-food industries.   Switching the biogas plant over to biomethane enables production continuity and fluidity, without stopping and without losses.  

• 25 Gwh/year, the annual energy supply of 4,904 homes.
• Reduction of CO₂ emissions by 4,550 tonnes/year, equivalent to the planting of 491,891 trees.
• Biomethane from industrial waste.

Promoter AXPO / HYSYTECH   This facility produces biogas from organic waste generated by cows, marking another milestone: it is the first to use organic waste generated by animals. This waste is enriched via a decomposition and enrichment process to convert it into renewable gas.   It is a fine example of supporting a sustainable economy, a circular economy and the use of an extremely abundant form of waste, the quantity of which can lead to problems elsewhere. Thanks to this plant, we ensure this resource becomes an opportunity.  

• 30 GWh/year of biomethane, enough to supply 5,885 homes.
• Reduction of CO₂/year by 5,460 tonnes, equivalent to the planting of 590,270 trees.
• Biomethane from organic livestock waste.

Promoter Naturgy   The state-owned company Edar Bens SA is responsible for treating the wastewater from council authorities in A Coruña and also represents a major milestone: in 2016, an initiative was launched to install the first Mixed Renewable Gas Unit. This unit increases the usage effectiveness of biomethane obtained from the treatment of urban wastewater. The goal is to achieve 100% useful power generation.   Given that the company was already using biomethane at its own installations, we partnered with them to inject their biomethane into the natural gas network and thereby harness this resource more efficiently.  

• 5 GWh/year of biomethane, enough to supply 980 homes.
• It will avoid emissions of 910 tonnes of CO₂/year, equivalent to the planting of 98,378 trees.
• Biomethane from the Waste Water Treatment Plant.

Promoter WAGA / Prezero   This facility, which treats urban and industrial waste from Barcelona and its area of influence, has been operated for more than 30 years by PreZero Spain, treating more than 22 million tonnes of waste during this period.   The waste stored at Can Mata produces almost 40 million cubic metres of biogas per year, used up to now to produce thermal energy for drying concentrates from leachate treatment, as well as for producing electricity and thermal energy to manufacture construction materials. Thanks to this new technology, the controlled waste repository will recover 100% of the biogas.  

• It will produce 71 GWh/year of biomethane, equivalent to the annual consumption of 13,929 homes.
• It will avoid the emission of 12,922 tonnes of CO₂/year into the atmosphere, equivalent to the planting of 1,396,972 trees.
• Biomethane from landfill waste.

Promoter Consorci Besos Tordera   By launching this project, Nedgia guarantees the injection of 28 GWh/year of biomethane into the grid, thus contributing to renewable gas penetration through its infrastructure.   The facility, driven by the Consorci per a la Gestió dels Residus del Vallès Oriental and the Consorci Besòs Tordera, produces biomethane from the management of 55,000 tonnes of organic waste and the treatment of 12 million m³ of wastewater per year.  

• It will produce 28 GWh/year of biomethane, equivalent to the consumption of 5,493 homes.
• It will avoid the emission into the atmosphere of 5,096 tonnes of CO₂/year, equivalent to the planting of 550,918 trees.
• Biomethane from the Waste Water Treatment Plant.

Developer Naturgy   After an investment of 1.5 million euros, this facility will become the third plant commercially operated by the company in Spain and the second in Catalonia, and that inject renewable gas into the grid.   The Naturgy plant, located on the Porgaporcs livestock farm in Vila-Sana (Lleida), will generate biomethane to supply the equivalent annual consumption of 2,354 homes and will prevent the emission of 2,184 tonnes of CO₂ per year into the atmosphere.   With this new plant, the company is taking a further step in its commitment to energy transition, local energy production and the circular economy, as it will supply clean gas to the energy system and contribute to the sustainable management of agricultural and livestock waste.  

• It will produce 12 GWh/year of biomethane, equivalent to the consumption of 2,354 homes.
• It will avoid the emission of 2,184 tonnes of CO₂/year into the atmosphere, equivalent to the planting of 236,108 trees.
• Biomethane from organic livestock waste.

Promotor FNX   Nedgia, gas distributor of the Naturgy group, and CycleØ have launched the first virtual gas pipe that will be capable of injecting renewable gas into the network from production points external to the infrastructure. This milestone is a major step forward for the development of biomethane, a carbon neutral gas obtained from waste treatment, in Spain, increasing the country's production potential and promoting the technical and economic viability of new developments.   The new virtual biogas pipeline will inject 40 GWh of renewable gas into the Nedgia network each year from different CycleØ production plants located in the province of Lleida. This amount is equivalent to the consumption of 7,847 households.  

• It will produce 40 GWh/year of biomethane, equivalent to the consumption of 7,847 homes.
• It will avoid the emission into the atmosphere of 7,280 tonnes of CO₂/year, equivalent to the planting of 787,027 trees.
• Biomethane from organic livestock waste.
