The KIKERP project develops an AI system that evaluates end-of-life appliances for repair or recycling, supporting resale via a cloud-based image recognition platform.

Fraunhofer ISE develops stable PCM emulsions with double water’s storage density for efficient thermal management in buildings, industry, and vehicles.

The AD Net Heat project models heat flows, predicts load peaks, and supports planning for complex, decentralized district heating networks with renewables.

In the BAU-DNS project, seven Fraunhofer institutes develop sustainable, modular refurbishment methods for buildings and present solutions at BAU 2025 in Munich.

The technology is assisting in the process of validating and certifying turbines and is supporting the transformation of the energy supply with a view to using more renewable energy sources.

Fraunhofer researchers have developed a solution that combines power from renewable sources with electricity from the public grid and uses batteries to compensate for fluctuations.

The smoodACT joint research project designed, developed and tested a building and district energy management system.

The new cloud software retoflow offers energy network operators an automated and efficient way to check these requests, model and simulate power grids and pipeline networks across sectors, and engage in long-term planning.

Large power stations with their large synchronous generators provide stability in the power grid, but are being successively powered down in the course of the energy transition. In order to address this issue, researchers at the Fraunhofer Institute for Solar Energy Systems ISE are working on how grid-forming converters can ensure a future supply of sinusoidal alternating current and stable grid frequency.

Fraunhofer researchers have developed an intelligent coating for glass windows that darkens in the sun. This uses electrochromic and thermochromic materials that react to electricity and heat. In buildings with large glass façades, it stops the rooms from getting too hot because of solar radiation, thereby reducing the demand for energy-intensive air conditioning.
