Façade-integrated R290 split-type heat pump for domestic hot water
Researchers in Austria have developed a new heat pump system for residential applications that reportedly achieves a coefficient of performance ranging from 2.82 to and 3.11 at an outdoor air temperature of 10 C and 20 C, respectively. They also found the system was able to supply the comfort conditions at all tested outdoor temperatures.

The Hydrogen Stream: Airbus, Vattenfall to assess potential for airport hydrogen
A new study by ManpowerGroup and Cepsa suggests that green hydrogen and biofuels could create more than 1.7 million new green jobs in Europe by 2040, while Airbus, Vattenfall and other partners have agreed to assess the feasibility of hydrogen infrastructure at airports in Sweden and Norway.
TSUN releases new series of microinverters
Chinese manufacturer TSUN says its Titan series of microinverters can handle 15 A of continuous input DC current. They also feature a 97.2% efficiency and four maximum power point tracking (MPPT) channels.
Sunrun solar-plus-storage powers the grid during peak demand
In partnership with utility Pacific Gas and Electric, the residential solar installer enrolled distributed batteries to serve the grid during times of peak demand.
Fred. Olsen 1848 deploys floating PV pilot in Norway
Fred. Olsen has completed a 124 kW pilot project to serve as a testing ground to refine its Brizo floating solar solution. The tech is designed to address challenges posed by wave and wind loads.
Robotic measurement system assesses new materials for solar cells
Researchers in Japan have developed an automated system to perform photoabsorption and photoluminescence spectroscopy, optical microscopy, and white-light flash time-resolved microwave conductivity tests.
Vitamin C treatment improves stability of inverted organic solar cells
Danish researchers report that treating non-fullerene acceptor-based organic solar cells with vitamin C provides an antioxidant activity that alleviates the degradative processes arising from heat, light, and oxygen exposure. The cell achieved a power conversion efficiency of 9.97 %, an open-circuit voltage of 0.69 V, a short-circuit current density of 21.57 mA/cm2, and a fill factor of 66%.
Organic cathode for high-energy, fast-charging lithium-ion batteries
Massachusetts Institute of Technology (MIT) researchers have developed a new organic cathode material with an energy density higher than most cobalt-based cathodes. It can charge–discharge in as little as six minutes. Automaker Lamborghini has licensed the patent for the technology.
