Solar Power Portal's sister site, Energy Storage News, visited the offices and production facilities of Sunamp, a maker of heat batteries, in East Lothian, Scotland.

The company’s low cost devices are created using phase change materials that retain heat once activated, and were developed in collaboration with the University of Edinburgh. We heard about what the systems can do and how they were developed from the University’s Professor Colin Pulham, Sunamp’s CEO Andrew Bissell and the company’s chief materials scientist Dr David Oliver.

Dubbed “the Scottish Tesla” by MP Fergus Ewing, in addition to being on sale commercially, hundreds of the devices are being installed as part of the Eastheat trial scheme for Local Energy Scotland, which is testing the viability of the technology, especially in combination with PV, to combat fuel poverty in social housing.
