Biofuel Infrastructure Partnerships
Ameresco & HASI Launched Its Neogenyx Fuels as an RNG Platform
Adam Harrie — May 11, 2026
Ameresco and HASI launched Neogenyx Fuels, a joint venture that spun out Ameresco’s biofuels business as a standalone renewable natural gas platform valued at $1.8 billion post-money. HASI is investing $400 million in the venture — $300 million for growth and $100 million directly to Ameresco — with a 70/30 ownership split.
Neogenyx enters the sector as one of the leading US biogas project developers, leveraging Ameresco’s 25-year development history. Forecasts indicate that RNG demand will increase from approximately 150 million MMBtu today to more than 600 million MMBtu by 2030.
Ameresco and HASI show how spinning a scaled biofuels business into a dedicated joint venture can unlock capital and strategic focus beyond what a corporate division can access alone.
