Series 15 – Episode 6 – Producing the world's first commercially viable heat battery

Sunamp has pioneered the development of innovative heat batteries that utilise phase change materials to revolutionise thermal energy storage. These advanced batteries store and release large amounts of thermal energy through the melting and solidifying of specially developed phase change materials, providing a highly efficient and sustainable solution for heating and cooling applications. Current products offer heat storage for domestic hot water, which is more space-efficient and energy-efficient than traditional hot water cylinders.

Sunamp's heat batteries boast superior energy density, rapid response times, and long-lasting performance compared to traditional storage methods. By integrating this cutting-edge technology into homes, businesses, and industrial processes, Sunamp is making significant strides in sustainable energy solutions, helping to reduce carbon emissions, enhance energy efficiency, and alleviate fuel poverty.

Bissell said: “Being nominated for the MacRobert Award is amazing recognition that underscores the profound impact dedicated teams can have on society and the planet, proving that with the right vision and determination even the smallest players can drive monumental change. It has been a privilege to work with the likes of Dr David Oliver who invented our stabilised formulation for Plentigrade phase change material; Maurizio Zaglio bringing fresh ideas from academia to model and refine the heat exchange process; Sandy Gataora bringing to bear decades of expertise from the world of HVAC and the whole team crossing disciplinary boundaries to bring something needed and new into the world. Overcoming these significant engineering challenges is not just an innovation, it’s a beacon of hope for reducing carbon emissions from heating and cooling around the world."
