The Austrian manufacturer said its new heat pump can achieve a seasonal coefficient of performance of up to 4.7 and flow temperatures of up to 75 C. It is available with sizes ranging from 2 kW to 7 kW.

Developed through bandgap engineering and material design, the proposed PV device relies on a tin-based perovskite material known as CsSnI3-xBrx. It can reportedly be further designed to achieve power conversion efficiencies exceeding 24%.

Scientists have investigated different techno-economic scenarios for using hydrogen storage in combination with hydropower and pumped hydro storage in Switzerland. They have found that hydrogen storage plays no major role under most conditions.

Grew Energy has started building a 3.2 GW ingot-module factory in India. The facility will produce 2.8 GW of ingots, wafers, and cells per year, along with 3.2 GW of high-efficiency PV modules.

A group of scientists in Thailand has outlined a new approach to avoid oversizing and overvoltage in energy markets applying volt-watt droop curtailment strategies. The novel methodology leads to a reduction in a PV system’s net present value but also increases its levelized cost of energy.

Renew Home, a partnership between Google Nest Renew and OhmConnect, aims to expand from 3 GW of electrical energy use to 50 GW by 2030.

AGL Energy has completed the installation of a solar-powered microgrid with a 5.4 MWh battery energy storage system in Australia to support the transition of a commercial orchard’s operations from diesel to renewables.

The European Commission has shared updated documents with its member states for speeding up permitting procedures and designing auctions for renewables. It includes the use of non-price criteria in auctions, which the commission says will allow higher value-added projects to be rewarded.

Heavy rains recently triggered floods in Brazil’s Rio Grande do Sul state when Lake Guaíba and the Taquari River and Uruguay River overflowed, reaching more than 5.30 meters and affecting more than 1.95 million people. The death toll stands at 143, with 125 still missing. The authorities still have yet to assess the losses from submerged or affected PV plants.

Consortia featuring subsidiaries of Chinese solar module maker Longi and Chinese industrial conglomerate Shanghai Electric have withdrawn from a public procurement tender for a solar park in Romania. The European Commission opened two anti-subsidy investigations into their involvement, which have now been closed.
