Enagás and other companies promote a biomethane plant in Jaén

Biomethane is one of the least developed renewable energy systems in Spain, despite its great potential, since it uses as raw material, among other things, the waste generated by industrial livestock farms. Now, a group of companies has decided to build a biogas plant in Jaén.

Enagás Renovable ─subsidiary of Enagás─, the energy engineering company Genia Global Energy, and the waste management company Grupo Valora, have developed a project to promote the creation of a biomethane production plant in Jabalquinto (Jaén).

This project, which was presented to the Territorial Delegation for Sustainable Development of the Junta de Andalucía in Jaén, contemplates the construction of a biogas production plant in the town of Jabalquinto, in Jaén.

“The initiative thus contributes to promoting decarbonisation and the circular economy, thanks to the recovery of waste. Specifically, this facility would allow up to 140,000 tons of different bio-waste to be processed per yearamong which are pig slurry, leftovers from the food industry, alperujos and process water, to convert them into biomethane equivalent to around 60 GWh of energy”, Enagás points out in a note.

It will also produce organic fertilizers

In addition, the circular economy processes of the plant would allow the generation of fertilizers and organic amendments ─materials of plant and animal origin─ aimed at improving the fertile capacity of crops and recover degraded areas.

“By means of this natural process, agronomically safe and without bothersome odors or insects, it would contribute to solving the problem of managing bio-waste that is especially complicated to treat, such as slurry or alperujo, which without being managed could contaminate soils or aquifers if they are poorly managed”, adds the company.

The project, which will entail the creation of more than 15 direct, permanent and qualified jobs, would also allow generate an economic ecosystem that would benefit bio-waste producers (oil mills, pig farms and the agri-food industry), transporters and farmers.

The implementation of this initiative, which would mean a saving in CO2 emissions of approximately 120,000 tons per year, is in line with the Circular Economy Plan for Europe ─EU Directive 2018/850─ on the management, treatment and recovery of waste for municipalities, the Law on Climate Change and Energy Transition of the Government of Spain, the National Integrated Energy and Climate Plan (PNIEC) 2021-2030 and the Energy Strategy of Andalusia 2030.

This project joins the plan of Enagás Renovable, Genia Bioenergy and Grupo Valora to develop three other additional projects in Andalusia, which would allow biomethane production to reach 200 GWh/year in total.

Take advantage of methane from livestock

Biogas is obtained through a process of biodigestion of organic waste, called anaerobic biodigestion, a natural process that accelerates the production of this ecological gasor 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 can be injected into the gas network 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 network of distribution and more than 19,000 that produce biogas for self-consumption or cogeneration.
