Solar seasonal storage system achieves 4.1 heat pump COP in greenhouse heating

South Korean researchers have demonstrated a small-scale solar seasonal thermal storage system integrated with heat pumps for greenhouse heating over three years. The system achieved average thermal storage efficiency of 55.1%, while the dual-source heat pump recorded an average COP of 4.1.

The race for space solar

The space economy could be worth as much at $2 trillion by 2040 – according to a recent report by professional services provider PwC. The cisLunar orbit, between the earth and the moon, is particularly promising. But all of it requires power and, as it has for decades, that means PV – and both the technology and supplier landscape for orbital solar is diversifying. Eternal Sun | WAVELABS‘ Pepijn Veling reports from a series of events the company has attended across the country, on what is a fast-evolving technology and business landscape.
