The purpose of Task 34 as part of the IEA Bioenergy Agreement
- Develop Biofuel standards to support commercialization of DTL technologies.
- Validate and standardize analytical methods for thermally liquefied biomass
- Encourage exchange of information with our stakeholders
- Support technoeconomic assessment of biomass liquefaction technologies
In partnership, we want you to:
- Let us know about new challenges you see in liquefaction technologies: contact your country representative for opportunities to get involved
- Publish your research updates to the Pyrolysis/Liquefaction Community in the next PyNe newsletter
- Reach out to authors in PyNe newsletter to exchange data and establish new collaborations!
