This website is designed and maintained by Aston University on behalf of Task 34 of the IEA Bioenergy Agreement through the Implementing Agreement on Bioenergy, which forms part of a programme of international energy technology collaboration undertaken under the auspices of the International Energy Agency.

Collaboration with Tasks 32, 33, 38, 39 and 42

In order to address the direction to increase inter-Task collaboration, four topic areas have been identified for cooperation with Tasks 32, 33, 38, 39 and 42. 

Assessment of Bio-oil Gasification

To collaborate with Task 33 we propose to complete an assessment of bio-oil gasification as a means to compare to solid biomass gasification. Bio-oil gasification is being studied in Germany by the Karlsruhe Institute of Technology as an optional means to make use of the processing advantages of a liquefied biomass in subsequent utilization. This optional use should be assessed to compare to direct gasification to determine the process advantages and other differences. This collaboration could lead to the development of comparative bio-oil and biomass gasification cost models.

Assessment of Bio-oil Combustion for CHP

To collaborate with Task 32 we propose to complete an assessment of bio-oil combustion for CHP as a means to compare to direct biomass combustion for CHP. Bio-oil combustion is the near-term application for bio-oil and it use should be assessed to compare to direct combustion to process advantages and other differences. The direct combustion of biomass is well understood in Task 32 and cost models have been developed. This collaboration could lead to development of comparative bio-oil combustion cost models.

Development of LCAs

As a point of collaboration with Task 38 we propose to make our process mass and energy balances available to Task 38 for the development of life cycle assessments (LCA) of the process options. Optionally the Task 38 effort may be more limited to the review of LCA methods and results from our efforts.

Data Base Development

An existing database structure will be used by adapting the Task 33 or Task 39 databases and the scope of database coverage will be extended to include pyrolysis-based approaches to liquid biofuels. Task 34 will be involved in stewarding the accuracy of information in the database that involves facilities using pyrolysis-based technologies. There are a number of private entities already tracking pilot/demo/commercial scale developments across the entire biofuels space, albeit at a shallow level of due diligence, so Task 34 has identified a need to evolve the database effort by adding value to the lists that already exist. Vetting/expanding/qualifying the information being aggregated by others is one way to do this.

Biorefinery Pyrolysis Development

This effort is an outgrowth of the work undertaken in the past triennium to develop the link between Tasks 34 and 42. In that effort a pyrolysis-based biorefinery concept was studied in the Netherlands. Pyrolysis of biomass is viewed as one of the promising primary biorefinery processes that potentially could be directly upstream (power plants, oil refineries) or downstream (biofuel, pulp/paper) integrated with conventional industrial infrastructures converting these infrastructures to highly-efficient, sustainable, multi-product biobased facilities. Within this Task a pyrolysis-based concept will be assessed as part of an overall sustainability assessment. Task 42 and Task 34 members will jointly define the concept and perform the assessment.
