Mitigating residential duck curve via solar pre-cooling
Solar pre-cooling consists of using residential PV systems to run air conditioners to pre-cool residential and commercial buildings. It offers benefits in terms of mitigating low minimum demand in electricity networks, flattening the grid’s net demand profile, and reducing electricity bills.
Weekend Read: Hopes washed away
The Ukrainian solar industry had hoped that a long-anticipated counter-offensive against the Russians would help reclaim PV assets on the eastern bank of the Dnipro River. The brutal reality is that the destruction of the Kakhovka dam has likely severely damaged solar plants in the affected territories, reports Ian Skarytovsky.
July’s irradiance up in most of South America, down east of the Andes
In a new weekly update for pv magazine, Solcast, a DNV company, presents the solar irradiance data it collected for South America in July. The data show that South America experienced temperatures up to 15 C above winter averages, and that most of the continent saw higher than normal radiation. The Chilean Andine, especially Altiplano in the Atacama Desert, which has recorded the highest incidence of irradiance in the world, recorded values 10% above normal.
Argentinian lithium miner sourcing electricity from 100 MW solar farm
Minera Exar has started to extract lithium from the Salar Cauchari-Olaroz mine in Argentina, with part of its energy supply coming from the 100 MW Zonda solar farm, which is owned by oil producer YPF Luz.
The Hydrogen Stream: Perovskites-based photoanodes for photoelectrochemical (PEC) water splitting
A research team has developed OHP-based photoanodes for photoelectrochemical (PEC) water splitting, minimizing the usual limitations. Meanwhile, China released its first hydrogen guideline, and Germany announced €18.6 billion for the hydrogen industry. Finally, a German company finds out that hydrogen trains are more expensive than battery-operated vehicles.
