WP1: Project Management

WP1 will ensure the overall project coordination and management and monitor the achievement of project deliverables and milestones. Futhermore, WP 1 will take care of the reporting to and contact with the European Commission. The establishment and regular updating of the project website will be carried out in the framework of this Work Package for communication between project partners, the advisory board and interested stakeholders.

WP2: Selection of biomass feedstock

The requirements of the producers of torrefied pellets and the end users will be identified followed by a market assessment in order to identify the available feedstock. On this basis, the types of biomass to be applied in the experimental work packages (WP3-7) will be selected.

WP3: Torrefaction

Lab/bench and pilot tests in different torrefaction facilities will be carried out in order to further optimise the torrefaction technologies, to broaden the feedstock range and to allow for the production of solid sustainable bioenergy carriers with properties meeting the requirements set by the subsequent densification, logistics and end use.

WP4: Densification

With the torrefied material produced in WP3, pelletisation and briquetting tests will be carried out in lab-scale and pilot-scale equipment. The main objective of WP4 is thus dedicated to characterize and optimize the densification properties of different torrefied biomass materials according to end user requirements.

WP5: Demonstration Tests

This WP concentrates on large scale demonstration tests for torrefaction and densification with the plant of Topell. The produced material will be used in the logistics and end use tests.

WP6: Logistics

The objective of this work package is to assess the transport, handling and storage properties of torrefied and densified biomass. This is done by small-scale tests to characterise logistics performance followed by larger-scale outdoor storage and handling tests to assess various logistics aspects and produce optimised torrefaction-based bioenergy carriers. Those can then be tested under real case conditions, e.g. in existing coal-handling lines.

WP7: End-Use

This WP will evaluate the end-use performance of torrefaction-based bioenergy carriers considering the four end-use options in SECTOR. The information gained can be used to develop optimised production recipes for torrefaction and densification in WP 3 and 4 and to identify optimum torrefied biomass chains in WP9, starting from raw biomass to heat, electricity, biofuels, bio-chemicals and/or bio-materials.

WP8: Fuel specification, lab analysis and quality assurance

Handling and conversion properties of torrefied (and densified) material are different to those of thermo-chemically untreated biomass, thus existing test methods need to be evaluated. This WP will also focus on the development of a Material Safety Data Sheet (MSDS) and on a draft for the new product standard in Europe (EN 14961-X) and a worldwide standard (ISO 17225) that are planned.

WP9: Value chains and sustainability

Based on the results of WP2, biomass-to-end-use-supply-chains, bridging the gap between supply potentials of torrefaction feedstock and demand potential from end-users will be defined. The chains will be evaluated in a socio-economic assessment and a life cycle assessment as defined by the international ISO standards 14040ff. and the EU RED Directive 2009/28/EC. 

WP10: Cooperation and Dissemination of project results

The objective of this WP is the dissemination and exploitation of the scientific and technical findings that will be generated within the project duration. In order to address scientific experts, stakeholders and technical committees several platforms and tools will be used for communication and transfer of information.

Furthermore, a technical report targeting the governments of the IEA bioenergy member countries (over 20 countries world-wide) will be prepared to provide key information on the possible ways for the use of torrefied biomass.
