Scientists in China have investigated the hydrodynamic performance of a novel modular floating photovoltaic system. They did so using a novel hybrid approach, which integrates viscous-flow effects from computational fluid dynamics into a potential-flow solver. They analyzed the new system with varying numbers of panels, either in a single chain or a parallel configuration.

The researchers developed a heat-driven thermoacoustic heat pump that can purportedly achieve a temperature lift of 125 C. It uses a thermoacoustic heat pump to stably release the heat from the engine unit. The system also includes a thermoacoustic engine unit and acoustic resonators.

The company said that its Dowsil EG-4175 Silicone Gel resists temperatures of up to 180 C in next-generation IGBT modules used in inverters.

Scientists at Italy’s University of Cagliari explored the integration of a water electrolyzer with a floating PV-pumped hydro energy storage system. They found that under high curtailment conditions, hydrogen production helped to stabilize system efficiency and lower the levelized cost of electricity when compared to a system without the electrolyzer.

A questionnaire and focus group study of households in the UK city of Bristol found residents have a lack of access to technical and ‘common sense’ information on the transition to heat pumps. Able-to-pay residents became more willing to invest as they learned about the technology.

An American research group has conducted a pilot workshop for agrivoltaics stakeholders in Arizona, including farmers, developers, government officials and indigenous leaders. A reflection paper offers some key takeaways for future public participation.

The Chinese company says that the new product is available in 40 kW, 50 kW, and 60 kW versions. The product has a maximum efficiency of 99%.

Scientists in Malaysia have conducted a techno-economic-environmental study of a green fueling system for a ferry that runs between islands in their home country. Using 40,000 solar panels, they were able to power two round trips round-trips per day. Annual CO₂ reduction was measured at 23.75 million kg.

Honeywell has launched its Ionic battery energy storage system (BESS) with integrated controls and energy management. The system is designed to cut energy costs, stabilize the grid, and provide backup power.

The microinverter company has disclosed details on the architecture of its IQ Bidirectional EV Charger, which will be available for sale in the second half of 2026. It is reportedly able to deliver up to 11.5 kW of bidirectional power.
