Subtask 2.1 – Robust end-of-life wind turbine blades waste prediction

Subtask 2.1 lead: WindEurope

Scope: The goal of Subtask 2.1 is to estimate future wind turbine blade waste in Europe and to formulate guidelines on how to perform this calculation. This subtask will take place during the first year of the IEA Wind Task 45 – Phase II, from Month 1 to Month 12 and will be coordinated by WindEurope. The purpose for the participants in this task is to provide support to WindEurope in realising a new and updated prediction of the upcoming volume of wind turbine blade waste. The goal of the task is also to formulate a guideline on how to calculate future volumes of waste (Deliverable 2.1). The support is in the form of feedback to review the models used to make the prediction and feedback to improve the guideline (Deliverable 2.2).

Deliverables

• D2.1 – Prediction of future amounts of European decommissioned wind turbine blade (WindEurope – Month 12)
• D2.2 – Guidelines for calculating future volumes of wind turbine blade waste – Format: word document (WindEurope – Month 12)

Subtask 2.2 – Reliable data to support the prediction of end-of-life wind turbine blades and the planning of end-of-life solutions.

Subtask 2.2 lead: NREL

Scope: The goal of Subtask 2.2 is twofold. First, it is to recommend a list of data to support the prediction of upcoming wind turbine blade waste. A starting point for this first goal is the documentation available in some countries. For example, in Denmark the stamdata register is available from the department of energy’s website. The second goal is to define the data needed to optimally support the planning of end-of-life solution for wind turbine blades. Identified data of importance that have been discussed among the partners are for example: external geometry, internal geometry, blade mass at stations along the length and total mass, material types, mass (or volume fractions) of fiber and resin in the laminates in the spar cap, shell and webs, adhesive type used for bonding parts together and certification reports for the blade. Deliverable 2.2 aims at the creation of a template to record and store relevant data. This subtask will take place during the second year of the IEA Wind Task 45 – Phase II, from Month 13 to Month 24 and will be coordinated by NREL. The purpose for the participants in this task is to participate in the creation of the template containing the relevant data regarding the installation and decommission of wind turbines and provide feedback in this process. The support is in the form of oral feedback, sharing the experience in the individual countries. The support will be provided during a series of meetings and workshop, online and in-person organized by NREL.

Deliverables

• D2.3 – A template for the registration of installation and decommissioning of wind turbines – Format: excel sheet (NREL – Month 24)

Subtask 2.3 – Harmonized policies on the recycling of blades

Subtask 2.3 lead: SDU

Scope: The goal of Subtask 2.3 is to investigate the impact of policy gaps, barrier and levers on the establishment of recycling solutions for wind turbine blades. This subtask will take place during the third year of IEA Wind Task 45 – Phase II, from Month 25 to Month 36 and will be coordinated by University of Leeds. The purpose for the participants in this task is to share knowledge and identify the policy gaps, barrier and levers for wind turbine blade recycling. The support from the participants is in the form of coordination (SDU), writing of a publication summarizing the findings (Deliverable 2.3), and knowledge dissemination. The support will be provided during a series of meetings and workshop, online and in-person, which will be organised by SDU.

Deliverables

• D2.4 – A publication identifying policy gap policy barriers and policy levers – Format: open access publication (SDU – Month 36)

Subtask 2.4 – Economic viability in the upscaling of recycling technologies 

Subtask 2.4 lead: Fraunhofer IWES

Scope: The goal of Subtask 2.4 is to build a cost model to estimate the cost related to the recycling of wind turbine blades (Deliverable 2.4). This subtask will take place during the last year of IEA Wind Task 45 – Phase II, from Month 37 to Month 48. This subtask is coordinated by Fraunhofer IWES. The purpose for the participants in this task is to support the development of the cost model for the recycling of wind turbine blades by sharing their experience. The support comprises feedback during the construction of the model and testing of the cost model (Milestone 2.1). The support will be provided during a series of meetings and workshop, online and in-person.

Deliverables

• D2.5 – A cost model predicting the cost of recycling a wind turbine blade – Format: excel sheet (Fraunhofer IWES – Month 48)

Milestone

M2.1 – Cost model tested and validated (Fraunhofer IWES – Month 44)

Subtask 2.5 – Joint IEA Wind Task 45 / VDMA Roadmap on composite recycling technologies

Subtask 2.5 lead: VDMA

Scope: The goal of Subtask 2.5 is to update the first version of the VDMA roadmap on composite recycling technologies, which will be created in 2024. This subtask will take place throughout the entire duration of the IEA Wind Task 45 – Phase II, from Month 6 to Month 48. This subtask is coordinated by VDMA. The purpose for the participants in this task is to support the update of the existing roadmap of VDMA on the recycling technologies for wind turbine blades. VDMA will invite the IEA Wind Task 45 members to regular meetings and workshop, online and in-person to publish an updated and joint version of VDMA roadmap on composite recycling technologies.

The support will be provided in the form of oral or written comments.

Deliverables

• D2.6 – An updated Joint IEA Wind Task 45 / VDMA roadmap on composite recycling technologies – Format: pdf document (VDMA – Month 24, 48)
