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.

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.

Heat exchanger for sorption thermal storage
The heat exchanger is built into a containment and the sorption material, small grains of zeolite, is filled between the heat exchanger plates. The total volume of material is about 400 liter. Heat is stored through the adsorption and desorption of water vapour in the zeolite. The water vapour is transported between the plates and collected in a header on top of the containment.

Carnot battery: power-to-heat-to-power system
A Carnot battery (power-to-heat-to-power system) converts electrical energy into thermal energy and stores it for a longer period of time before converting the stored energy back into electrical power. Carnot batteries are used for long-term, seasonal storage of electrical power and also heat, and can therefore contribute to stabilizing the power grid and storing electricity from renewable energy sources.

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.
