The groundbreaking solution for multi-hour energy storage from Azelio is a combination of field-proven technology and truly disruptive innovation. We have developed and enhanced the Stirling engine for many years, as well as optimized our Concentrated Solar Power (CSP) solution for this particular system. Together with our new innovation within Thermal Energy Storage (TES) we have created a solution with outstanding results.
The success of Concentrated Solar Power (CSP) is based on the ability to store accumulated heat – thermal energy. This is where Azelio’s system excels. But in order to concentrate the solar energy into the thermal storage, the actual capturing needs to be optimized for the system as a whole.
Our concept is set up by a fan-shaped heliostat field of an average 50 controlled mirrors of 3m², fitted in up to nine rows. The size can be fine-tuned and adjusted, depending on the local conditions. The mirrors reflect the sun rays up to the power unit that contains the heat storage and the Stirling engine, situated on a tower, eleven meters high.
Working with controlled mirrors has many advantages. The technology is well tested, and the production cost is relatively low. Maintenance is easily handled. There is also a possibility to fine tune every unit. For every kWh produced our solution needs less mirror area (in comparison to traditional CSP), resulting in less money spent for each installation.
Put together this means that, when in full production, we can offer a much lower LCOE (Levelized Cost of Electricity) than all other competing technologies on the market today.
