Is thermal storage a viable solution for electric HVAC & hot water systems?

Cheap and safe thermal storage offers a potentially viable solution allowing electric HVAC & hot water systems to be deployed with minimal impact on the grid. We propose such a multi-function thermal system combining solar photovoltaics, heat pump, and thermal storage for supplying residential heating, cooling and hot water demand.

What is solar-powered residential heating?

Spanish heating specialist Elnur Gabarron has developed a new solar-powered residential heating concept based on the use of storage heaters. “Our storage heaters are specially designed to work on grid-connected PV installations, using surplus power to produce sustainable heating,” a company spokesperson told pv magazine.

Can a residential thermochemical energy storage system be used with solar power?

France-based FHE Group has developed a residential thermochemical energy storage system that can be coupled with solar power generation to provide space heating and hot water to a household. “Our storage system can ensure a solar self-consumption rate of 100%,” the company's CEO and founder, Jonathan Laloum, told pv magazine.

What is a thermal energy storage system & heat pump system?

Thermal energy storage system: The system has a cold and a hot storage tank acting as thermal batteries to store energy for the AC & DHW system. Heat pump system: It includes two air-source heat pumps producing hot and chilled water. The details of these heat pumps have been provided in the appendices.

What is a rooftop photovoltaic (PV) system?

Rooftop photovoltaic (PV) systems and heat pumps are the most mature technologies to electrify heating and cooling in buildings and reduce the carbon footprint in this sector . The current low prices of rooftop PV systems allow for large residential installations with a peak power of well above 5 kW in many developed countries.

Can a solar heating system be used as a backup?

The solar-powered residential heating system can work as a backup solution, combined with existing conventional heating. Alternatively, it can serve as a household’s main heating system with minimal use of grid electricity. Spanish heating specialist Elnur Gabarron has developed this new concept based on storage heaters.
