As part of the IEA Bioenergy Agreement, the purpose of Task 34 is to:

  • 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:
