Azelio continues its progression towards the large-scale commercialization of its Stirling engine based power storage solution, which produces cost-effective sustainable electricity on demand around the clock. The system's unique long -term energy storage capacity - allowing for the production of electricity for 13 hours at nominal power - rests on a thermal energy storage solution. The key to the system's effectiveness is the ability to pump sodium around it at a high temperature (600°C), which is why Azelio has collaborated with Egger – a leading manufacturer of advanced pump systems - to develop a tailored solution.
"The Swiss manufacturer Egger specializes in the development of pump systems that work with difficult mediums, and is therefore the most suitable partner for us as we develop a solution that meets our stringent power and performance requirements," said Jonas Karlsson, Vice President of Development at Azelio.
In practice, the pump system drives heat through two pumps: one that heats the thermal storage unit while the other transfers heat from the storage unit to the Stirling engine.
The pump system has been tested, and it works well in controlled development environments. The system is now going to be verified by running a life-length test for 4,000 hours and by exposing it to real-life circumstances.
"This represents another important milestone for Azelio," said Jonas Eklind, CEO, Azelio. "The pace of our business remains high, and it's great that we can now demonstrate to the market that this critical part of our solution works in real-life environments, delivering on the promised performance."
Emile Egger & Cie SA, which has developed complex pump systems for a whole variety of applications for a range of industries, regards the collaboration as highly positive.
"We are proud of being able to offer our expertise and create a unique system that helps to give more people access to a reliable and effective power supply," concluded Francis Krähenbühl, CEO, Emile Egger & Cie SA. "Azelio is developing a system of great interest, and we look forward to contribute to its market
