Azelio first unveiled its advanced energy storage technology back in June 2018. It is based on a thermal energy storage system, and featuring a Stirling engine for dispatchable electricity production. The technology is well adapted to solar regions and is designed especially for areas where the electricity grid is unstable or lacking. Now, the technology has been broadened so that electricity from a wider range of sources can be received and stored as thermal energy.
The broadened use of the core technology comes as a result of a large and continued investment in research and development. The new solution utilises the same technology as previously to move heat from the storage to the Stirling engine.
Azelio already offers a solution for storage of solar energy to secure a sustainable distributed baseload in areas with high solar irradiation. That solution can serve as a low-cost replacement for the diesel-generated electricity used in microgrid systems. The opportunity to use electricity generated by other renewable sources, such as solar PV and wind to heat the energy storage, now means that Azelio can complement established technologies with energy storage systems, allowing low-cost renewables-generated electricity to be produced on demand around the clock.
The technology plays its part in the wider energy transition from fossil fuels, in particular for places where renewable electricity production is intermittent due to weather conditions, or excessive load placed on the grid.
Jonas Eklind, CEO of Azelio said: “Now that we can charge our storage with directly sourced electricity, we can reach more geographically varied markets, including Sweden and other parts of northern Europe. We can boost the competitiveness of sustainable alternatives and in this way facilitate the increased use of sustainable electricity. The cost of renewable technology is continuously falling, but the lack of competitive energy storage has worsened the imbalance between production and demand. We now have a solution. The cheaper solar and wind power become, the more competitive Azelio’s solution will be, providing a clear benefit to us and all of our customers."
