Technology and R&D

UK researchers have found a way to reduce the risk of electrocution with electric vehicles, while US utility Duke Energy said it is exploring how the Ford F-150 Lightning can serve as a grid resource. Chinese carmaker Geely posted disappointing first-half results, while IHS Markit said it expects strong uptake of battery electric vehicles in Europe through to 2030.

Scientists in Taiwan demonstrated a new way to produce high-purity lead-iodide, as a precursor material for a perovskite solar cell. By using temperature to better control the orientation of crystals, the group was able to show much higher efficiencies when the precursor was used to fabricate a perovskite layer and subsequently a working solar cell.

Australian researchers have developed a way to use rooftop PV to run air conditioners to pre-cool residential and commercial buildings. They have identified several factors that could help reduce a building’s energy costs.

TotalEnergies said its new 111 kW pilot facility in France will show the impact of solar panels on agricultural yield, while also shedding light on biodiversity, carbon storage, and water quality.

Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.

Italy added 303 MW/632 MWh of distributed energy storage capacity in the first half of 2022. The segment continues to grow in the country, with the regions of Lombardy and Veneto being the two largest contributors.

Quick and versatile, batteries are providing a growing number of services to homes, businesses, and on the grid. Electricity network operators are beginning to adopt grid-scale batteries, with the initial applications potentially opening the way for renewable energy to flow more freely and across larger distances than ever before.

Gasunie will establish a total storage capacity of approximately 26 million kilograms of hydrogen, with the first storage facility to be operational by 2026. Porsche Engineering has revealed its findings on the potential of hydrogen combustion engines, while hydrogen plans advanced in Australia and Portugal.

Nine partners from seven European countries are involved in the €3.6 million ($3.7 million) “Reveal” research project, which says buildings could be heated in the future by storing energy from PV, wind and water in aluminum.

Researchers in South Korea have reported success in developing large-area, indium tin oxide-free, flexible organic solar cells. Their zinc oxide bilayer-based organic solar cells demonstrated an efficiency of 7.67% for a module area of 528 square centimeters.
