Decarbonising industry and district heating networks is one of Europe’s biggest energy challenges. DigiSolar aims to transform large-scale solar thermal (ST) systems by integrating them with other renewable energy sources, enabling hybrid-ST solutions that enhance decarbonization and energy flexibility. This approach accelerates the energy… ...

The project supports the development of reliable large-scale solar thermal fields in Switzerland through a practical, hands-on toolkit, including guidelines and the development of a Python-based backend for the calculation and design of solar fields. It is carried out in collaboration with AEE INTEC, combining the expertise of experienced national… ...

The analysis of the integration of large TES in District Heating Networks (DHNs) and renewable sources requires dynamic simulation to address the fluctuating behaviour of sources and sinks. The development of dynamic simulation energy system models requires experience, data for validation, and, above all, it is time-consuming. The need to evaluate… ...

The overarching aim of RE-WITCH is to deliver cost-competitive, game-changing solutions in the field of sustainable industrial cooling and heating. To do so, RE-WITCH will demonstrate advanced thermally-driven industrial cooling technologies based on ADsorption and ABsorption processes driven by an optimized mix of low-grade waste and renewable… ...

The EU-funded SOLINDARITY project aims to transform the industrial landscape by introducing a solar-powered heat enhancement system. Targeting industrial processes with temperatures up to 280°C, SOLINDARITY integrates a range of innovative and highly efficient components, including thermal solar collectors, thermal energy storage, photovoltaics and… ...

To complete the deployment of the ice slurry technology using the supercooling water, modelling and design tools for the scalability of crystallizers are required. These tools may ensure a controlled and reliable operation of crystallizers, avoiding upstream ice propagation and exergetic losses, and high-efficiency supercooling release. To achieve… ...

The Solindustrias project aimed to establish the technical and economic foundations for the successful use of solar heat for industrial processes (SHIP) in Cuenca, Ecuador, by transferring knowledge, piloting and demonstrating SHIP applications, and promoting these technologies among other industrial end-users as well as local and national… ...

Thermocline is a cost efficient thermal storage system able to reduce capital costs of CSP up to 40 %. The objective of this project is to develop new thermocline concepts that can be applicable to different CSP plants. Detailed simulation of two thermocline concepts will be validated with the experimental data generated in this project. Based on… ...

In «Slurry-Hp I» we have shown the potentials of cost reduction of using the ice slurry technology with the supercooling method for solar-ice applications. First work on supercoolers was done in «Slurry-Hp II» and it is currently being developed in the «H2020 TRI-HP». «Slurry Store» will work towards the development of an ice slurry storage concept… ...

The overall goal of the TRI-HP project is the development and demonstration of flexible energy-efficient and affordable trigeneration systems. The systems will be based on electrically driven natural refrigerant heat pumps coupled with renewable electricity generators (PV), using cold (ice slurry), heat and electricity storages to provide heating,… ...

The idea behind this project is to use the supercooling ice slurry method for solar heating applications. This innovative concept could provide a breakthrough in solar and heat pump systems with ice storages by reducing the cost of the system by 10 %. The cost reduction would be achieved by eliminating the heat exchangers from the ice storage and… ...
