Uniper and Biotrend explore Türkiye's biomethane potential

Uniper and the Turkish energy company Biotrend Enerji have signed a Memorandum of Understanding to assess the production and potential export of biomethane from Türkiye to European markets. The partners will explore converting Biotrend’s existing waste-based biogas plants to produce renewable gas.

Biomethane can replace natural gas in existing infrastructure, making it a readily available option for reducing emissions in industry and transport, particularly where electrification is difficult. For Uniper, this cooperation is another tangible step in executing its strategy to expand its portfolio of renewable and low-carbon gases. It has the potential to provide an additional source of renewable gas and help diversify its supply portfolio.

The Memorandum of Understanding was signed in the presence of Hendrik Wüst, Minister-President of the State of North Rhine-Westphalia, Germany, and Hakan Göral, Group CEO of Doğanlar Holding in Istanbul, Turkey.

Michael Lewis, Chief Executive Officer of Uniper, said:

“European industry needs reliable and competitive options to reduce emissions. Biomethane can use existing gas infrastructure and be supplied to customers without requiring fundamental changes to their processes. The cooperation with Biotrend could open up a new source of renewable gas for European markets while further diversifying Uniper’s portfolio.”

Hakan Göral, Group CEO of Doğanlar Holding, said:

“Biomethane offers significant potential to transform Türkiye’s waste and biogas resources into a higher-value renewable gas source. Through the Memorandum of Understanding with Uniper, we intend to explore opportunities for biomethane production in Türkiye and the potential to access European markets. Biotrend’s operational experience in waste management and biogas provides a strong foundation for assessing this potential.”

Turning waste into renewable gas

Türkiye has untapped an biomethane potential of up to 50 terawatt-hours per year. Biotrend, part of Doğanlar Holding, is a major Turkish waste-management and landfill operator. Its existing portfolio offers estimated biomethane production potential of around 1.4 terawatt-hours per year.

The partners will assess whether Biotrend’s existing biogas-to-power facilities can be upgraded to produce biomethane from organic waste. Uniper will contribute its experience in sourcing and commercializing renewable gases as well as in sustainability standards, certification and regulation.

Subject to the necessary Turkish regulation and European certification, the biomethane could be injected into the Turkish gas grid, transported towards Greece or Bulgaria and imported into the European Union.

For Uniper, the project would complement its growing biomethane activities in Europe. The company has already secured future supplies from three Spanish plants and operates an integrated biomethane-to-bio-LNG supply chain using existing infrastructure at the Gate terminal in Rotterdam.

The Memorandum of Understanding covers the initial project-development phase and does not constitute an investment or offtake decision. Any future projects will depend on regulation, certification and technical and commercial viability.
