KET awarded for two projects at KlimaExpo.NRW

KET was awarded for two projects at KlimaExpo.NRW, thus making a critical contribution to the energy transition in North Rhine-Westphalia. The Chair of Thermodynamics and Energy Technology (ThEt) of Prof. Vrabec achieved the reduction of the energy consumption of household refrigerators by up to 17 percent with the project "Efficient Refrigerators" using latent heat and cold storage based on integrated phase-change materials (PCM). The project "Power to Heat OWL", which was carried out by the Department of Power Electronics and Electric Drive Technology (LEA) by Prof. Böcker, successfully demonstrated that the intelligent control of heating systems can adapt the electricity consumption to the fluctuating electricity production from renewable energies and thus reliving the electricity grids. KlimaExpo.NRW is an initiative of the NRW state government and awards positive examples of climate protection in North Rhine-Westphalia until 2022.

Project „MoLaWS“ successfully started

In cooperation with ESDA Technologie GmbH, the project MoLaWS - "Development of a modular heat storage system using high-capacity, innovative latent heat storage elements " has been successfully started with a kick-off meeting at Paderborn University. The aim is to develop a new, modular, air-guided heat storage system consisting of innovative low-pressure-loss and cascadable high-performance latent heat storage elements. The aim is to adapt the heating and cooling supply to the current demand and to minimize the cost-intensive consumption of electricity and fossil fuels. The focus of KET is on the modeling and CFD-based investigation of the heat transfer processes induced by the phase change as well as on the design of the heat storage elements in regards to optimal heat transfer. The project is funded by the German Federal Ministry for Economic Affairs and Energy (BMWi) as part of the Central Innovation Program for SMEs (ZIM) with €188,690.

Increasing the lifetime of PV-Modules

KET has started the €535,000 funded project “SoLifE”
In cooperation with Solarword AG and ESDA Technologie GmbH, KET started a project aimed at increasing the lifetime of PV-modules. Within the next three years, the practical integration of phase-change materials into the next generation of PV-modules will be investigated under the coordination of Prof. Dr. Stefan Krauter. The main factors contributing to the degradation of the modules can be limited using targeted cooling and temperature stabilization of the solar cells. The German Federal Ministry for Economic Affairs and Energy (BMWi) supports this project by contributing €535,000.

“Storages from North Rhine-Westphalia for a step change in the Energy Sector” at a NRW parliament event on 30.10.2015

KET discussed the topic of energy storages with representatives from research, industry, and parliament and presented ongoing projects; for example “Intelligent Domestic Appliances as Virtual Large-Scale Consumers.”
