• About Us

    SynchroStor is an engineering R&D business founded in 2017 with the express purpose of developing a cost-effective grid-scale energy storage technology using pumped heat.

    After a number of years working in collaboration with Edinburgh University, SynchroStor has now moved to our own facilities south of Edinburgh.


Our research and development has been supported privately by our founders and industry stakeholders but also by InnovateUK through the Catalyst programme and by Department for Business, Energy & Industrial Strategy (BEIS) through the Energy Storage Cost reduction competition and more recently through the BEIS Long Duration Energy Storage (LODES) Stream 2 competition.

Development Status

So far, we have focused on de-risking the most innovative sub-systems in the PTES. Comprehensive numerical modelling has been undertaken and proof of concepts have been demonstrated. SynchroStor’s objective now is to further develop the sub-systems and ultimately combine these in a 1MW x 10MWh pilot demonstrator. We expect a pilot to validate the technology at TRL 6 while preparing for market entry.

The LODES programme also allowed SynchroStor to develop a detailed Feasibility Study for the technology. This scope of work also included a market study, system costing, CO2 abatement analysis and a technology risk assessment. This work was well aligned with SynchroStor’s roadmap and has provided more evidence to support our plans for whole-system demonstration.

The Team

The SynchroStor senior team has considerable experience of working in the startup environment, liaising with established contractors to provide specific expertise and design capacity as we grow. Our stakeholders bring the perspective from the end-users and the OEM. As such, our team is fully vertically integrated – from the designer to the end user.
