Objetive
This initiative is formed by a collaboration with the University of Castilla-La Mancha (UCLM). Project IDI-20250573 funded by CDTI.
BioSCGas aims to develop innovative and scalable renewable energy models for green hydrogen production, contributing to a decarbonised energy system while promoting circular economy principles. To achieve this, the project focuses on the sustainable production of biohydrogen and biomethane as core energy vectors, ensuring both environmental and economic viability.
The approach is based on the valorisation of diverse organic waste streams, including wastewater, sewage sludge, the organic fraction of municipal solid waste (FORSU), and agri-food residues, through a combination of bio electrochemical, biological, and thermochemical processes. Wastewater is not only used for energy recovery via bio electrochemical pathways, but is also regenerated to obtain water suitable for electrolysis, enabling the production of high-purity hydrogen at competitive costs. In parallel, advanced biological processes are investigated to enhance the generation and purification of biohydrogen and biomethane from solid and semi-solid organic wastes.
Complementing these routes, catalysed supercritical water gasification is explored as a thermochemical pathway for converting high-organic-content feedstocks such as biowaste, sludge, and digestates into hydrogen-rich syngas. In addition, high-pressure storage systems are investigated to take advantage of process conditions. The project also addresses the separation and purification of gas mixtures containing hydrogen, methane, and carbon dioxide, together with the capture and valorisation of CO₂ streams generated throughout the processes.
