Germany’s Bosch has developed an air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 3.9 kW and 6.7 kW of heat, and domestic hot water to a temperature of up to 75 C. It says the heat pump can be paired with rooftop solar to maximize self-consumption.

Australian materials tech developer Kinaltek has unveiled a one-step production process that it says can convert common silica powders into battery-grade nanosilicon for less than 5% of the cost of existing technologies. The innovation paves the way for the use of silicon nanoparticles in high-performance lithium-ion batteries.

Energy Systems Catapult has released interim data from air-source heat pump field monitoring in the United Kingdom between November 2020 and August 2022. Figures show that heat pumps are three times more efficient than gas boilers and that their median coefficient of performance (COP) on cold days is 2.44, compared to 2.80 year round.

After 800 Sungrow batteries were impacted by an outage, the Chinese manufacturer informed its local German partners about the solution to the problem. However, it remains unclear how quickly the affected battery management systems can be replaced.

Germany’s AEG is selling two versions of its new high-voltage residential batteries, with nominal capacities of 10 kWh and 15 kWh. They come with a 10-year warranty and reportedly have a lifecycle of more than 6,000 cycles.

More and more people want to invest in PV arrays and battery storage systems. However, there are a number of myths that could lead to disappointment among customers, according to one German consumer association.

Mitsubishi Electric has developed an air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 5 kW and 8.5 kW of heat and domestic hot water to a temperature of up to 75 C.

Zendure’s SolarFlow batteries have capacities of 960 Wh and can be stacked up to 3,849 Wh. The US manufacturer wants to begin selling the plug-and-play systems in April.

York Minster, one of the largest cathedrals in Northern Europe, has secured approval to install 199 solar modules on its rooftop. The system will generate at least 75,000 kWh per year and will be paired with batteries.

The “Solar Box” mobile power plant is a container consisting of solar modules, a battery storage system, and a hydrogen storage system. According to Austria’s Alternative Energy Projects (AEP), the system starts at 94 kW and can be scaled up to more than 5 MW.
