Structure and projects in Task 39
IEA Bioenergy Task 39 is structured into three subprograms: Technology and Deployment, System Analysis and Sustainability, and Outreach and Dissemination. During this triennium, six thematic projects are being implemented, as shown in the graphic. The projects and subprograms led by Austria are indicated with the Austrian flag.

Kick Off Meeting des IEA ES Task 48 am KTH in Stockholm Oct. 13th 2025
We successfully kicked off Task 48 at KTH Royal Institute of Technology in Stockholm - together with our colleagues from Task 47: Components for Thermal Energy Storage. We are inspired by the energy and expertise everyone brought to the table. Our discussions set a strong foundation for collaboration on advancing thermal energy storage (TES) materials — including phase change materials (PCM), thermochemical materials (TCM), and high-temperature sensible storage. Over the coming months, we’ll work together to develop measurement guidelines for TES materials, compile an overview of innovative TES materials and build a shared, high-quality TES materials database. A big thank you to Saman Nimali Gunasekara and colleagues for hosting and to all participants for their inspiring contributions!

Who does it themselves? Household and energy-related tasks by gender
The chart shows the proportion of women and men who stated that they carry out the following tasks themselves: Traditional household chores such as doing the laundry, cooking, shopping for food, cleaning, washing up and tidying up are predominantly carried out by women. Technical and administrative tasks such as liaising with the energy supplier, technical tasks, managing finances and carrying out repairs are predominantly carried out by men.

Cluster analysis of types of households
The cluster analysis identified four descriptive household types based on patterns of energy use, environmental attitudes, financial concerns and household characteristics. Typ A – „Engagiert & befähigt“ (34%) and Typ B – „Distanziert & abgesichert“ (35%) represent relatively less vulnerable households, while Typ C – „Besorgt & belastet“ (25%) captures households facing intersecting financial, housing and care-related pressures, and Typ D – „Energiearm & depriviert“ (7%) represents the most severely affected group. Given the moderate distinction between clusters, these types should be understood as indicative patterns rather than fixed or sharply defined categories.

Circularity and Climate Neutrality for transportation services
A product or service is “climate neutral“ and “circular“, if its whole life cycle - production, operation and end-of-life - uses only • reused components (reuse index), • secondary/recycled material (recycled content), • renewable energy, and makes • zero waste and • zero GHG emissions. In Figure 2, this definition is shown for supplying a 100% circular transportation service with its closed material cycle, which is driven by renewable energy. A mobility demand is satisfied by transportation services that are provided by a closed material cycle using renewable energy.

System boundaries for the eight analysed cases and the petrol ICE as reference
In Figure 3 the system boundaries for the V2X use cases are shown. For the cases without smart or bidirectional charging an additional electricity storage in the grid is considered.

Stand of the different baterry technologies (IEA 4E EDNA Task on Batteries).
This graphic shows the state of the art of different battery technologies. 14 types are organized according to their state of development. 10 are lithium-based batteries, the other 4 use various chemistry compositions (Zinc or carbon nano-tubes), or use new concepts to increase their capacity.

Temperature profiles in different materials
Comparison of simulated temperature profiles in TABS elements for varying materials with con-crete (left), and spruce and beech timber (middle to right) as specimens. To reach the same surface temperatures and therefore heating and/or cooling powers, significantly higher flow tem-peratures within the timber elements is necessary due to the much lower heat conductivity.
