heat storage

A British-Chinese research group has developed a novel heat pump concept consisting of a heat pump, the PCM tank, and tube solar heat collectors. Intended for demand shifting in space heating and domestic hot water (DHW) applications, the system is reportedly able to achieve a higher coefficient of performance than conventional heat pumps.

Shell has provided Australian startup MGA Thermal with “game-changer” funding to accelerate the completion of a commercial-scale pilot storage plant.

German researchers have developed a new shape-stabilized phase change material with the ability to store up to five times more thermal energy than commercially available PCMs.

France-based FHE Group has developed a 2.5 kWh storage device that can store electricity as heat during the day and release this heat at night to power a heat pump for space heating and hot water. According to the manufacturer, it can retain over 95% of its initial performance after 20,000 cycles.

In an update to a report it published earlier this year, Norway-headquartered consultancy DNV GL outlined the role it sees for both seasonal heat storage and pumped hydro to help manage the 1.4 TW of variable renewable energy capacity it forecasts to be connected to European electricity grids by 2050. DNV GL maintains the original report’s conclusion that where seasonal storage is concerned, hydrogen will be the first option.
