Azelio, based in Sweden, unveiled its energy storage technology in 2018. That technology is based on a thermal energy storage system developed by Azelio, which features a Stirling engine for dispatchable electricity production. The solution is adapted to solar regions and used particularly in areas where the electricity grid is either unstable or entirely lacking.

With a new development Azelio has broadened the range of uses of its unique technology, so that electricity from a wider range of renewable sources can be received and stored as thermal energy. Given the importance of storage to the broader development of renewable energy, Azelio believes this is significant.
The new solution, which enables electrical heating of the energy storage, uses the same technology previously used 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 PV and wind to heat the energy storage, now means that Azelio can complement established technologies with energy storage systems, allowing low-cost electricity generated by renewables to be produced on demand around the clock.
Azelio sees this as a unique solution to the challenge of transitioning from fossil fuel technologies, where the electricity production of renewable sources is at present characterized by weather-dependant intermittency of production, as well as excessive load placed on the electricity grid, which was not designed for this new paradigm.
“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 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,” says Jonas Eklind, CEO Azelio.
