H2 production from urban and forestry waste
Entity:
Development of technologies that allow the use of waste that is difficult to manage, such as urban, agricultural and forestry waste, in the form of renewable hydrogen.
Specifically, the extranet works on the bio-refinery concept as a promising alternative for the production of biofuels and other high value-added molecules from catalytic processing of biomass and organic residues. Different technologies have been developed and are being researched for the processing of forest residues and organic waste into biofuels. Notable among which are catalytic processes using new microwave reactor designs, which allow depolymerisation of biomass into high value-added molecules such as glucose and xylose, levulinic acid, furfural, hydroxymethyl furfural, carboxylic acids, etc., which can be new platform molecules for green chemistry, and catalytic reforming for the production of green H2 from biomethane and water.
Challenges met
Scaling up technologies to produce renewable H2 as an alternative to H2 from natural gas through the revalorisation of:
- Agricultural and pruning waste
- Municipal organic fraction
Scope of application
- Recycling and composting plants
- Incineration plants
- Controlled landfills
