The British Business Bank led a £10m funding round to support international demonstration projects and research.
"The renewable power market is held back by its vulnerability to external factors. The answer is long-duration energy storage, and Certain Energy has the technology and now the funding to deliver highly efficient, affordable batteries, based on abundant materials, to make this a reality."
The funding round was led by Mercia Ventures and will support team expansion and platform development.
"Our mission is to simplify the complex world of energy and building management systems, empowering building operators to reduce carbon emissions and save money. Our focus on tangible results has led to a huge increase in demand from businesses to join the Grid Edge community. This funding will enable us to welcome more businesses on board, accelerating our growth and extending our reach and impact."
The Oxford spinout secured £9.2m from new and existing backers to scale its smart hot water technology.
"Mixergy is launching a new integrated heat pump cylinder in the Spring, which uses our top-down heating technology, with a small heat pump attached to the cylinder. It will heat water 10x faster than conventional integrated heat pump cylinders (usable hot water in under 30 min), and connect to the grid."
The Series A round was led by Earthworm with participation from InnoEnergy, Crowdcube, and Centrica to accelerate international expansion and product development.
"At Earthworm we are driven by sustainability and Verv represents a brilliant example of ‘enabling’ technology. Its energy metering, analytics and renewable energy trading platform will help millions to reduce energy consumption, to shift their demand to minimise cost and CO2."
