Renewable Gas Rises as Heygaz Scales Across Europe

Backed by InfraVia and lenders, Heygaz accelerates 15-plus biomethane projects across Europe, signaling a new phase for renewable gas

2 Mar 2026

Europe’s renewable gas race has shifted into a higher gear. With fresh backing from InfraVia Capital Partners and a syndicate of institutional lenders, Heygaz is moving aggressively to scale more than 15 biomethane projects across the continent.

The corporate financing package is structured in tranches, starting with an initial round that supports projects already in development. Additional funding is expected as the portfolio matures, giving the company flexibility to expand its footprint in Spain, Portugal, Ireland, Norway, and Greece. In a sector often slowed by fragmented funding, that structure could prove decisive.

Biomethane has become strategically vital as governments seek to curb reliance on imported fossil fuels. Under the EU’s REPowerEU plan, policymakers are pushing for a sharp rise in renewable gas output by 2030. Heygaz’s capital injection positions it to build new plants and upgrade existing biogas facilities so they can inject biomethane directly into national grids.

Unlike traditional project-by-project financing, this platform-level approach allows capital to be deployed dynamically. Management can prioritize the most advanced or high-impact assets, accelerate timelines, and pursue acquisitions in a market that remains fragmented. The result is a faster, more coordinated buildout at a time when scale matters.

The deal also reflects a broader shift in investor sentiment. Biomethane platforms are increasingly viewed as long-term infrastructure plays, similar to renewable power portfolios. InfraVia’s involvement signals growing institutional confidence that renewable gas can deliver steady returns alongside decarbonization gains.

Demand fundamentals are strengthening as well. Industrial buyers and transport operators are intensifying their search for low-carbon fuels, driven by regulatory pressure and energy security concerns. Expanding domestic production promises more stable, localized supply and the potential for sophisticated cross-border contracting models.

Challenges persist, from feedstock competition to uneven grid access and patchwork regulations. Navigating those hurdles will require disciplined capital allocation and close coordination with national authorities.

Still, momentum is unmistakable. With capital flowing and policy tailwinds intact, biomethane may be edging from niche solution to a cornerstone of Europe’s evolving energy system.
