Uniper signs seven-year biomethane supply deal with Spain’s Five Bioenergy

10 October 2025 | Hamburg / Madrid — German energy company Uniper has entered into a seven-year agreement with Spanish biomethane developer Five Bioenergy for the purchase of biomethane from three production plants located in Murcia, Spain. Deliveries are scheduled to commence in early 2027.

Under the deal, Uniper will procure biomethane to strengthen its portfolio of low-carbon energy sources and support decarbonization across multiple sectors, including road transport and maritime.

“The agreement places us in a strong position to complement the growing share of renewables with low-carbon energy sources and to accelerate the decarbonization of both road and maritime sectors,” Uniper stated.

Carsten Poppinga, Chief Commercial Officer at Uniper, said:

“We are very proud to partner with the leading Spanish biomethane developer Five Bioenergy. The supply agreement underscores our ambition to expand and diversify our low-carbon energy portfolio. By sourcing high-quality biomethane, we are not only strengthening our supply sources but also advancing the decarbonization of our operations. We look forward to a productive and innovative partnership with Five Bioenergy, and to realizing new low-carbon opportunities together that will help to create a cleaner and more resilient energy future.”

Ivan Copin, Chief Investment Officer of Five Bioenergy, added:

“This collaboration with Uniper validates our strategy of merging cutting-edge technology with industrial-scale production. It secures a stable market for our biomethane while reinforcing our vision of a decarbonized Europe powered by renewable energy. Far more than a commercial deal, this partnership is a decisive catalyst for accelerating the energy transition and advancing a circular economy.”

Uniper’s broader decarbonization strategy

Uniper aims to achieve full carbon neutrality by 2040. As part of its long-term transition strategy, the company is diversifying its gas portfolio to include green gases such as hydrogen and biomethane, with plans to convert its infrastructure accordingly.

The biomethane agreement follows several recent initiatives by Uniper to expand its low-carbon capabilities. These include a partnership with thyssenkrupp Uhde to advance ammonia cracking technology, a memorandum of understanding (MoU) with Kyuden International to explore cooperation in hydrogen, ammonia, renewable energy, and carbon capture, and a conditional term sheet with Provaris Energy and Norwegian Hydrogen for the supply, transport, and offtake of hydrogen from the Nordics to north-western Europe. Uniper’s collaboration with Five Bioenergy represents another step in the company’s commitment to building a resilient, low-emission energy system in Europe.
