An international group of researchers has calculated the potential for floating solar across the world. The results show a generation potential of 9,434 TWh per year across 114,555 global reservoirs, with 30% of their area covered. The United States leads with 1,911 TWh per year of potential, followed by China at 1,107 TWh per year and Brazil at 865 TWh per year.

Samsung and the city of Oxford in the UK have announced the trial of a neighborhood heat pump scheme in Rose Hill, Oxford. The project aims to connect communities to local installers, helping to remove key barriers to heat pump uptake, including cost. Up to 150 Samsung air-source heat pumps will be installed at a reduced price of GBP 2,600 ($3,185) each.

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.

Reshoring crystalline silicon PV panel manufacturing to the United States by 2035 could cut greenhouse gas emissions by 30% and energy consumption by 13% from 2020 levels, according to scientists from Cornell University.

Researchers in Singapore have developed a perovskite solar cell via a new method to synthesize the capping without using lead. The cell is capped with a zinc-based compound and reportedly has a conversion efficiency of 24.1%.

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.

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.

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.

US-based Ascent Solar said its factory for copper indium gallium selenide (CIGS) thin-film PV modules is now dedicated to the industrial commercialization of its perovskite solar tech, which is reportedly showing lab efficiencies above 20%.

Vaillant has revealed that it has opened a new heat pump factory in Slovakia. The facility will exclusively make heat pumps from May, with an expected annual output of 300,000 units.
