Swedish SaltX chosen as a preferred energy solution for City of Helsinki

Calix Limited (ASX:CXL), is pleased to see that its partner in developing a novel renewable energy storage system, SaltX (Nasdaq First North: SALT B), has won the Helsinki Energy Challenge for its novel renewable energy storage technology.

To find the best modern solutions for heating Helsinki in the future, significantly contribute to the cessation of coal use by 2029 and become carbon neutral by 2035, the City of Helsinki created the Helsinki Energy Challenge, a global competition with a prize of one million euros. 

Swedish-based SaltX Technology is developing a patented energy storage solution based on a specially prepared salt. Calix recently announced its partnership with SaltX for Calix to design and construct a pilot scale 200kW electric-powered direct separation reactor (eDS) in Sweden, to be used as part of this process for storing and despatching renewable energy.

Phil Hodgson, CEO of Calix, said, “We congratulate SaltX on winning the Helsinki Energy Challenge, which is testament to the potential we see in the SaltX technology, and we are proud to be partnering with SaltX in this development”.

SaltX also is partnering with Rebase Energy, which provides digital tools for the optimisation of distributed energy storage systems. The entry, titled ‘Smart Salt City’, offers a functional and sustainable system that is well suited to cities that have set the ambitious goal of carbon neutrality but have high energy consumption and need a reliable energy supply for their residents and businesses. 

The solution melds the beauty of novel energy storage and artificial intelligence with commercially available energy technologies, and provides an opportunity for cities to use renewable energy sources in a safe and economical way, without having to plan for new and expensive infrastructure for hydrogen and avoid potential investments in new nuclear power to secure energy capacity.

Together with three other winning entries, SaltX and Rebase Energy will share EUR 1 million. The money will go towards continued development and future investments of both companies' technologies. Discussions with the City of Helsinki will also begin concerning the development and implementation of the technology.

252 Entrants from more 35 countries submitted outline proposals in the first stage of the year-long Helsinki Energy Challenge. Ten finalists in the challenge were notified on 6 November 2020, receiving €10,000 each to continue elaborating their solution in greater detail in partnership with the City of Helsinki.

Carl-Johan Linér, CEO of SaltX Technology, said this is an important milestone for SaltX. 

“It confirms that our energy storage solution can play a central role in future fossil-free cities. In the work of finalising the entry we have added even more competence to our team which we will use in our commercialisation going forward. I acknowledge and thank the City of Helsinki for being bold and showing the way for other cities.”
