Renewable Gas Injections in the EU Rise to 4.3 bcm Over Two Gas Years, ENTSOG Reports

Renewable gas injections into natural gas grids across the European Union have climbed steadily over the past two gas years, reaching 4.3 billion cubic meters (bcm), according to the latest assessment by European Network of Transmission System Operators for Gas (ENTSOG).

The report, covering the period from October 1, 2023, to September 30, 2025, examines annual renewable gas injections into transmission and distribution networks. It encompasses both biomethane and renewable hydrogen.

Steady Growth in Renewable Gas Volumes

According to ENTSOG, renewable gas injections rose from 38.1 TWh to 43.2 TWh over the two most recent gas years—equivalent to approximately 4.3 bcm—representing an annual increase of 12%.

This marks ENTSOG’s second dedicated report on renewable gas injections into European gas networks. The first assessment was included in its 2024 Annual Report, published in April 2025, and covered data for the 2023–2024 gas year.

The latest growth was primarily driven by the commissioning of new biomethane plants and existing facilities reaching their nominal production capacity.

Renewable hydrogen injections remained limited. Germany was the only member state reporting hydrogen injection into its gas system, with volumes declining from 3 GWh to 1 GWh during the reporting period.

It should be noted that the report does not account for biomethane flows occurring outside transmission system operator (TSO) and distribution system operator (DSO) grids.

Biomethane Growth Without Major Infrastructure Investments

Piotr Kuś, ENTSOG’s General Director, emphasized that renewable and low-carbon gases can be readily integrated into existing natural gas infrastructure, supporting the transport of sustainable and secure energy molecules.

He stressed that gas TSOs will continue to provide the necessary infrastructure to facilitate the energy transition.

“In particular, biomethane market growth can be facilitated without the need for significant infrastructure investments. This growth is essential if we are serious about meeting the EU’s REPowerEU target of 35 bcm biomethane by 2030,” Kuś said, referring to the European Union’s REPowerEU objectives.

Five Countries Dominate Renewable Gas Injections

The distribution of biomethane injections varies significantly among EU member states. Five countries—France, Germany, Denmark, Italy, and Netherlands—accounted for 94% of total renewable gas injections, the report reveals.

Several member states reported no injections, in some cases due to on-site consumption of renewable gases that eliminates the need for grid injection.

Among the five leading countries, all recorded significant increases in biomethane injections into TSO and DSO grids during the last gas year.

France posted a 2 TWh rise in injections, reaching 13 TWh—approximately 1.3 bcm—by the end of the reporting period. The increase was attributed to the continued rollout of new injection points and the gradual ramp-up of production sites to full operational capacity, a process that often takes time following initial commissioning, according to the Report on Annual Renewable Gas Injections into Gas Networks.

Sunotec advances Germany’s largest EEG hybrid power plant

Sofia-based solar and battery developer Sunotec announced a key milestone in the construction of the Hybrid Power Plant Zerbst. The company claims it is set to become Germany’s largest solar-battery hybrid power plant under the Renewable Energy Sources Act (EEG).

Located on a 41-hectare former gravel pit, the site combines 73,000 solar modules with a capacity of 46.4 MWp and a 57 MWh battery energy storage system (BESS).

The facility is designed and built to operate as a fully co-located hybrid asset, providing grid-supportive, dispatchable renewable power, Sunotec explained.

The project is being developed by Statkraft

The project is being developed by Statkraft. The Hybrid Power Plant Zerbst will deliver 50,000 MWh of renewable electricity per year. It is sufficient for 14,000 households.

This is the company’s first hybrid power plant in Germany and a proof of concept for its fully integrated, beyond-EPC delivery model, according to Sunotec.

The model is different from a traditional EPC contract. Sunotec implemented the core phases of the Zerbst hybrid power plant internally, including engineering, geotechnical assessments, and environmental planning.

Following completion, Sunotec will continue to manage the operations and maintenance of the PV plant.

​Atanasov-Lankes: we demonstrate the strength of Sunotec’s integrated model

This integrated approach reduces interfaces, eliminates fragmentation, and guarantees high-quality delivery, the company said.

“With the Hybrid Power Plant Zerbst, we demonstrate the strength of Sunotec’s integrated model and our ability to deliver complex systems at scale,” Zharin Atanasov-Lankes, Managing Director of Sunotec Germany, stressed.

He underscored that the project reflects the engineering depth and execution capability of the firm’s teams.

Over the last six months, Sunotec has made major steps in developing its operations in Europe.

In November 2025 the company signed an agreement with oil and gas major Shell on the development of battery energy storage systems in Central Eastern Europe. In July it has agreed with China-based Sungrow to install 2.4 GWh of BESSs.
