Europe’s Biomethane Gamble

Europe’s energy market is buzzing over biomethane. The latest signal came this autumn as Verdalia Bioenergy secured a landmark €671 million financing package to expand its portfolio of biomethane facilities in Spain and Italy, underscoring investor confidence in renewable gas as part of the continent’s energy transition.

Verdalia’s strategy is straightforward: build and acquire plants that turn organic waste into biomethane — a high-grade, low-carbon version of biogas — through anaerobic digestion. The company’s portfolio now spans operational and under-construction plants in Italy and Spain and aims for more than 3 TWh of annual production, enough to supply nearly a million homes.

This growth isn’t happening in isolation. Across the EU there are now more than 1 600 biomethane plants producing around 7 billion cubic metres a year. Investment commitments from the private sector total over €28 billion ahead of 2030, and policy frameworks like the EU’s REPowerEU plan explicitly call for scaling biomethane to help decarbonise European energy systems and reduce fossil fuel dependence.

Spain and Italy, two of Europe’s emerging biomethane hubs, highlight different but complementary drivers. In Spain, abundant agricultural waste and strong renewable commitments have drawn investment from firms and lenders such as the European Investment Bank and private groups linking biomethane production with circular economy goals. €80 million in framework financing backed by the InvestEU programme is enabling development of multiple biomethane plants designed to inject renewable gas into the existing grid.

Italy has placed similar emphasis on integrating biomethane infrastructure into its broader gas network. An EIB–Snam loan of up to €264 million will help build hundreds of kilometres of dedicated pipelines to integrate biomethane from new producers into the national system, aligning with its National Recovery and Resilience Plan.

Supporters argue that biomethane plays to Europe’s strengths: it uses existing gas infrastructure, reduces greenhouse gas emissions, bolsters energy independence, and contributes to local economies by turning waste into energy. On that basis it is seen less as a replacement for large base-load sources such as nuclear or thermal generation and more as a flexible supplement that can dovetail with renewable electricity, hydrogen and other low-carbon fuels.

Yet sceptics ask tough questions about its commercial viability. Bioenergy research and policy initiatives have been underway for decades, and critics argue that past optimism has often outpaced impact. Bioenergy’s costs, reliance on consistent biomass supply and competition with other decarbonisation technologies have slowed its penetration. While markets for biomethane are expanding rapidly — with analysts predicting multi-billion-dollar growth over the next decade — its share of total energy remains modest.

For investors the calculus comes down to risk and perspective. Biomethane projects benefit from clear policy support and bank financing demonstrating institutional backing. But they are also exposed to feedstock price volatility, regulatory shifts and competition from increasingly cheap renewables and green hydrogen.

Whether this latest wave of investment marks a turning point or merely prolongs a long running experiment in decarbonisation will depend on how effectively Europe integrates biomethane alongside broader clean-energy strategies rather than expecting it to shoulder the transition alone.
