<h3>Accepting the SolarPACES Technology Innovation Award 2025 for the Innovative High-Temperature Air-Based Integrated CST for Flexible Renewable Heat are Pok Wan Kwang and Gediz Karaca from ODQA, with Rafael Guedez, Silvia Trevisan and Konstantinos Apostolopoulos-Kalkavouras from KTH</h3>
<p>The 2025 Technology Innovation Award was jointly presented to <a href="https://www.odqa.com/about" rel="noopener" target="_blank">ODQA</a>, a University of Oxford spin-off, together with <a href="https://www.kth.se/directory/m/mje/mjec" rel="noopener" target="_blank">KTH Royal Institute of Technology</a>, for their pioneering work advancing high-temperature air-based industrial heat.</p>
<p>ODQA’s rotary receiver generates air at above 1000 °C, adapting principles from gas turbine engineering, while KTH’s radial packed-bed thermal energy storage efficiently stores and releases this heat on demand, reducing pressure drops by over 50% and system costs by 60%. KTH’s research turned these concepts from laboratory experiments into proven prototypes, leading successful integration and testing with ODQA’s rotary air receiver, thus making flexible, cost-effective industrial-scale solar heat. Proven at pilot scale with industrial hot air applications, their integrated system is advancing through demonstration at PSA, offering a scalable path to decarbonize high-temperature industries with renewable solar heat.</p>
