Livoltek launches 120 kW EV chargers
China’s Livoltek says it has developed 120 kW electric-vehicle chargers with 140 kW input and a 100 kWh LFP battery, supporting the CHAdeMO, GB/T, CCS1, and CCS2 standards.
Storing surplus PV power with thermal storage electric boilers
Tokyo-based heavy industry manufacturer IHI Corporation has created a thermal utilization system that can convert surplus direct current power at solar plants into carbon-free steam. A test project that commenced in April has used all generated electricity and is operating stably, the company says.
Daiwa House unveils solar carport
Daiwa House, Japan’s largest homebuilder, has developed a new carport made from extruded aluminum profiles. It comes in two versions, accommodating either four or two vehicles.
Dual-source CO2 heat pump based on photovoltaic-thermal evaporators
Researchers in Italy have conceived a dual-source heat pump system that uses both a finned-coil evaporator and a solar evaporator made with three photovoltaic-thermal panels. Thanks to the combined action of the two evaporators, the heat pump can achieve higher evaporation pressure and coeffficient of performance.
Platio debuts new walkable solar panels
The Hungarian company said its new products can handle a load of 300 kg. The modules are available with power outputs of 23.65 W and 59.68 W and can be integrated with wood-plastic composite, wood, stone, or ceramic floorings.
Computer vision for real‑time shadow detection in PV systems
Scientists have developed a novel method that uses live video feed to detect shadows on solar panels. It uses computer vision techniques, such as gamma transform and histogram matching, resulting in performance that is reportedly better than conventional techniques, especially in large arrays.
Longi, ANU develop gettering-based process to improve n-type wafer quality
The Chinese module maker and the Australian National University utilized phosphorus diffusion gettering and another defect mitigation strategy to improve the quality of n-type wafers. The proposed process contributed to improve the material quality especially towards the tail-ends.
Firebrick thermal energy storage could reach 170 GW in the U.S. by 2050
Firebrick heat storage technology, not batteries, will be used to store energy for industrial process heat in a 100% renewable energy system, says a study out of Stanford University.
The Hydrogen Stream: Equatic making anodes to produce H2 from seawater
Equatic says it has started annual production of 4,000 anodes for hydrogen generation from seawater in Singapore and Canada, while Nuvera Fuel Cells says it will demonstrate its first operational hydrogen-powered AC generator set and DC fast charger.
German startup offers design tool for heat pump installers
German software company Autarc launched a platform for residential heat pump projects, covering design, planning and customer project management functionality. It uses LiDAR imaging to enable heat load and hydraulic balancing calculations, as well as visualizations.
