V2G tech can provide outage support, claim Australian researchers

Researchers at the Australian National University (ANU), Canberra, have shown that their response to a February 2024 grid emergency provides evidence that electric vehicles (EVs) equipped with vehicle-to-grid (V2G) systems could strengthen the grid during blackouts, marking a global first for such research.

Residential PV power forecasting method based uniquely on direct radiation

Researchers in Spain have created a novel PV forecasting method that uses only direct radiation as a parameter. They found it to be “comparable, if not superior” to four established forecasting techniques. The method could help homeowners with PV systems decide when to use electricity-intensive appliances and cleaning systems.

Hungarian startup offers PCM-based thermal battery with energy density of 30 kWh/m3

Hungary-based Heatventors is offering its new thermal energy storage system with capacities of 10 kWh, 30 kWh, and 60 kWh. The thermal battery is combinable with solar PV and has an expected service life of over 10,000 cycles.

VIPV in refrigerated trucks can ‘easily’ offset energy demand it creates and meet chiller demand

Germany’s Fraunhofer ISE investigated thermal effects and net energy gains of a 3.2 kW vehicle integrated PV (VIPV) system installed on a freight truck with a refrigerated cargo storage area. It found that with battery storage the system could potentially meet the entire energetic needs of the cooling unit throughout the year in some cases.

Navien unveils residential air-source heat pump

The South Korean heating specialist said its new heat pump can achieve a seasonal coefficient of performance of up to 4.87 and flow temperatures of up to 75 C.

U.S. researchers build 16%-efficient mini perovskite solar module resistant to UV light-induced degradation

A U.S. research team has built a 15 cm2 perovskite solar module with improved stability and efficiency thanks to a polymer hole transport layer that reportedly improves the panel stability and efficiency.
