Repsol has agreed to buy 40 percent of Genia Bioenergy, a Valencia company that turns farm and livestock waste into biomethane. Repsol says the deal positions it as an integrated player across the biomethane value chain. What it is integrating with, for now, is mostly a pipeline of plants that are not yet producing.
Key takeaways
- Repsol announced on 10 April 2024 that it had signed an agreement to acquire a 40 percent stake in Genia Bioenergy, the renewable gases division of Spain's Genia Global Energy.
- Leap records a deal value of $117 million for Repsol's 40 percent stake in Genia Bioenergy, although the announcement itself did not disclose a price; grossed up to 100 percent, that implies about $292.5 million for the whole company.
- Genia Bioenergy's portfolio targets more than 2.8 TWh a year of biomethane production, made up of 19 late-stage plants totalling 1.5 TWh a year and 11 early-stage projects that Enerdatics understands total 1.3 TWh a year.
- Genia Bioenergy aims to reach 10 TWh a year of biomethane production by 2030, and the 2.8 TWh portfolio represents nearly 30 percent of that goal.
- Enerdatics records nine Spanish biomethane transactions from January 2023 to June 2025, and only four of them, including Repsol's Genia deal, carry a value.
What is Repsol buying into?
Biomethane is biogas cleaned up to the same quality as natural gas, so it can be injected into the existing gas grid and burned or processed in the same equipment. Genia makes it by digesting agricultural and livestock waste, such as manure, slurry and crop residues, from sites in Spain and Portugal.
Genia was founded in 2013, and Leap records it as the only company in Spain that integrates the whole biogas and biomethane value chain. It does engineering, project development, construction and operation in house, and it has worked for clients including Covap, Naturgy and Suez Environment. That breadth is the point of the deal for Repsol. Buying a stake in a company that already knows how to design, permit and run plants is faster than building that capability from scratch.
The output fits Repsol's own plans. The biomethane will go to Repsol's internal consumption and to its customers. Under its 2024 to 2027 strategy, Repsol is turning its industrial complexes into multi-energy hubs that make lower-carbon products, and renewable gas feeds directly into that model.
How much of the 2.8 TWh actually exists?
The headline portfolio is more than 2.8 TWh a year of production capacity, nearly 30 percent of Genia's 10 TWh goal for 2030. The breakdown tells a more cautious story. The late-stage part is 19 plants under development with a projected 1.5 TWh a year. The rest is 11 early-stage projects, which Enerdatics understands will add about 1.3 TWh a year. Together they make up the 2.8 TWh.
In other words, the portfolio Repsol is valuing is a development pipeline, not a running fleet. Early-stage biomethane projects still need land, feedstock supply agreements, permits and a grid injection point, and each of those can fail.
The plants that followed the deal show what each plant costs. In April 2024, Genia moved ahead with a plant in Tortosa and Campredo in Catalonia: a direct investment of $16 million for 93 GWh a year, processing 127,000 tonnes of waste a year on 8.5 hectares. In May 2024 it moved ahead with a second plant in Salamanca, at Machacon, with an investment of $27 million for about 70 GWh a year from up to 150,000 tonnes of manure and slurry. Separately, Genia owns half of The Green Vector, a platform with Enagas Renovable to develop 10 waste-based plants in Spain.
What does the $117 million imply?
Leap records the consideration for Repsol's 40 percent at $117 million. A minority stake has to be grossed up before it can be compared with anything, because the price covers only part of the company. Dividing by 40 percent gives an implied value of about $292.5 million for all of Genia Bioenergy.
Set against the 2.8 TWh pipeline, that is roughly $104 million per TWh a year of targeted production. Set against the plant costs above, the implied company value equals the investment for about 18 Tortosa-sized plants. Either way, Repsol is paying for development rights and know-how rather than for steel in the ground.

Enerdatics records 51 European bio-fuel transactions from January 2023 to June 2025 whose records involve biomethane, and only 12 of them carry a value. In Spain the count is nine, with four valued: Redexis' $24.03 million biomethane portfolio in March 2024, Repsol's Genia stake in April 2024, Ence's $18.21 million La Galera plant in December 2024 and Naturgy's $562.82 million majority stake in a biomethane portfolio from ID Energy Group in May 2025. Three of the other Spanish deals are joint ventures to develop new plants, with Naturgy, Cepsa and PreZero among the partners. The pattern is clear: Spain's gas and energy groups are assembling biomethane pipelines mostly through stakes and partnerships, and only one of the valued Spanish deals, Ence's, bought an operating plant.
What does the deal signal for Spanish biomethane?
Spain's large energy companies are buying capability, not volume. The Spanish Gas Association, Sedigas, estimates biomethane could cover almost half of Spain's current natural gas consumption, and the EU wants production to rise sharply by 2030. Reaching that scale needs teams that can develop and run plants, and Leap describes Genia as the only company in Spain that integrates the whole chain.
That makes minority stakes in specialist developers the entry route of choice, a theme also visible in how utilities are building biomethane platforms the vertical way elsewhere in Europe. For Repsol, which has also been selling down stakes in operating Spanish wind and solar, Genia is a bet in the other direction: early-stage gas assets that will need years of building before they produce.
