As part of the COMHPTES project, our researchers visited SynchroStor headquarters in Edinburgh, Scotland. The visit marked the beginning of the collaboration, providing valuable insights into the integration of innovative energy storage technology.

A team from HPT traveled to Edinburgh to meet with SynchroStor , a key consortium partner in the COMHPTES  project. SynchroStor has developed a novel modular compressor/expander machine designed for Pumped Thermal Energy Storage (PTES). Within the COMHPTES project , this machine will be experimentally validated for use in a high-temperature CO₂-based heat pump, aimed at improving industrial heating and cooling applications.

The visit allowed HPT researchers— Rafael Guédez , Silvia Trevisan , Jens Fridh , Emily Fricke , and Zanil Narsing —to explore SynchroStor’s experimental setups and discuss the integration of their technology into KTH’s Heat and Power Technology lab facilities. The SynchroStor team—Jacob Ahlqvist, Chris Hannon, Harry Simpson, Jérémie Lagarde, Tim Putzien, Alexis Dole, and Jan Oledzki—provided a detailed tour, showcasing the inner workings of the compressor/expander machine and demonstrating its testing capabilities.

This visit was an important step in aligning research efforts and strengthening collaboration between KTH and SynchroStor, ensuring a smooth path forward for the experimental validation phase of the project.
