Enagás S A : Enagás Renovable and Genia Bioenergy present 'The Green Vector' platform to promote biomethane in Spain

The circular economy model that these plants will introduce will make it possible to generate a network that integrates all the agents in the waste recovery chain - composters, waste managers, farmers, livestock farmers, agri-food industry - and connects them with the town councils of the different localities and areas close to the location of the plants.

According to Gabriel Butler, CEO of Genia Bioenergy, "among TGV's goals is to drive the decarbonisation of the economy by offering energy from renewable sources in a process that wants to give a role to all actors in waste and biomethane management."

Five new biomethane plants in Spain by 2026

The Green Vector is currently promoting five new biomethane production facilities in Spain, with planned commissioning dates until 2026.

In November 2021, the two companies announced the first of the projects: the construction of a biomethane plant in Vencillón (Huesca). This facility, scheduled to begin construction in 2024 and with an estimated investment of more than 15 million euros, will be capable of digesting more than 140,000 tonnes of organic waste (mainly manure) and converting it into biomethane with an energy capacity of almost 100 GWh each year, thus avoiding the emission of approximately 150,000 tonnes of CO₂ equivalent into the atmosphere per year.

In November 2022, the construction of a biomethane plant in Lugo was announced, with an energy capacity of more than 100 GWh per year, which will enable the conversion of around 150,000 tonnes of bio-waste into renewable energy per year.

Of the remaining plants, two are in Valencia, one with a recovery of up to 180,000 tonnes of organic waste to produce more than 80 GWh of energy per year, and the other with a planned energy production of 100 GWh from 130,000 tonnes of bio-waste per year. The fifth planned plant is in Albacete, with a valuation of 100,000 tonnes of organic waste to also produce more than 80 GWh per year. All of them have the land identified and secured.

The objective of the two companies is to expand this network of facilities with new projects that will be announced as the locations are finalised and the corresponding processing process is initiated.

TGV brings together, on the one hand, Enagás Renovable's experience in the development and promotion of renewable gases and, on the other, Genial Bioenergy's technology and capacity to manage and integrate all the players in the waste recovery chain.

Sustainable economic ecosystems in rural environments

The biomethane production plants developed by TGV will generate economic ecosystems around waste (with specific treatment and recovery processes) that will contribute to the sustainable development of society, especially in rural areas. These facilities will generate circular economy models, which will create jobs, investment and boost local economic growth, while reducing the environmental impact of waste management.

How biomethane is generated

Biogas is obtained through a process of biodigestion of organic waste, called anaerobic biodigestion, a natural process that speeds up the production of this renewable gas with a high concentration of methane, thanks to the action of bacteria that live in the absence of oxygen.

Through an upgrading process, the resulting biogas is purified into biomethane, with similar characteristics to natural gas, so that it can be injected into the gas grid for distribution, which would allow homes, industries and vehicles to consume energy from renewable sources.

In Europe there are about 800 plants that inject biomethane into the distribution network and more than 19,000 that produce biogas for own consumption or cogeneration.
