HAM develops compact Bio-LNG liquefaction plant
Published on: Aug 1, 2025
The EU co-financed project targets decentralized production of renewable LNG from biogas.

Spanish company HAM Group, in collaboration with HAM Criogénica, has developed the R&D project NANO BIOGAS LIQUIFIER, aimed at designing and validating a next-generation, compact, and energy-efficient plant for local production of Bio-LNG (renewable liquefied natural gas) from biogas.
The advanced technology enables small-scale biodigesters to convert biogas into a competitive renewable fuel, supporting sustainability in both the transportation and agricultural sectors. This project's goal is to offer a modular “plug & play” liquefaction unit capable of processing biogas with outstanding energy efficiency.
The innovation allows renewable Bio-LNG to replace fossil-based LNG in heavy transport applications, directly contributing to decarbonization targets through the adoption of renewable biofuels. It also enhances the economic viability of small agricultural producers.
The NANO BIOGAS LIQUIFIER project involved a total investment of over one million euros, co-financed by the European Union (through FEDER and CDTI). The outcomes have validated a standardized modular solution for biogas liquefaction and the development of a cryogenic system that enables real-world Bio-LNG production under simulated field conditions.
Designed for remote, automated operation via integrated SCADA systems and PLCs, the unit offers a flexible, scalable solution for decentralized renewable LNG production.
