Scientists in Spain have developed a new heat pump that can produce 6.49 kWh of heat for each kilowatt-hour of power it consumes. The device could generate hot water at a temperature of up to 75 C.

Swiss Clean Battery is set to start commercial production of its pure solid state batteries in Switzerland. The batteries are based on a protected electrolyte made of a solid ion conductor, which helps to maintain internal resistance and capacity. The fixed ion conductor is formed in the battery cell itself, similar to a multi-component adhesive.

Scottish Development International and J-DeEP are developing a floating offshore hydrogen production plant off the coast of Scotland. Research shows the combination of large-scale offshore renewables and floating hydrogen production could soon become viable, depending on the project configuration.

Under a new energy strategy, the UK government aims to expand solar deployment by up to five times by 2035, in addition to developing 24 GW of nuclear power by 2050 and 50 GW of offshore wind by 2030.

South Africa’s Department of Mineral Resources and Energy (DMRE) has kicked off the sixth round of the Renewable Energy Independent Power Producer Procurement Program (REIPPPP). It aims to procure 1 GW of PV and 1.6 GW of wind power.

Photovoltaic shades in buildings offer energy efficiency and electricity generation, but an international research group says their commercial viability will depend on the control strategies used to optimize performance.

German renewable energy developer Juwi has completed a 204MW solar plant with more than 500,000 JinkoSolar PV modules. The company said it is currently Europe’s largest bifacial solar park.

Stanford University scientists have developed a solar cell with 24 hours of power generation via an embedded thermoelectric generator, which extracts power from the radiative cooler at night. Extra daytime power from excess heating comes from the cell itself.

SMA is offering a new line of four inverters with power ratings of 12kW, 15kW, 20kW and 25kW, for use in rooftop PV systems up to 135kW in size. It claims the inverters provide grid-compliant power control of entire systems and enable over-dimensioning of PV arrays by up to 150%.

US scientists have developed a battery that can retain 92% of its initial capacity over periods of 12 weeks, with a theoretical energy density of 260 W/hour per kg. It was built with an aluminum anode and a nickel cathode, immersed in molten-salt electrolyte.
