UK government warns of global warming risks related to hydrogen leaks
The UK Department for Business, Energy and Industrial Strategy has published new research showing that hydrogen leaks could have an indirect climate-warming impact, partly offsetting efforts to reduce carbon dioxide emissions.
Storing renewables with Brayton pumped thermal energy storage
UK researchers have designed a pumped thermal energy storage system for large-scale grid electricity, stored as high-grade thermal energy. It is based on a Brayton PTES concept demonstrated by Isentropic Inc., and consists of two insulated containers filled with gravel, and hot and cold vessels operating at different pressure levels.
Madrid’s airport to host 120 MW solar park
Adolfo Suárez Madrid–Barajas Airport in Madrid will open a new 120 MW PV plant as part of a bigger, €350 million ($380.8 million) solar deployment plan.
Bangladesh’s highest-opex rooftop PV plant goes online
Bangladesh has inaugurated its largest rooftop solar array under the opex model, at a location south of Dhaka.
Modular PV and wave power desalination buoys from Canada
A floating, reverse-osmosis-based unit turns seawater into potable drinking water through the power of the sun and waves. Oneka developed the product, which requires no external electricity source and no land.
US government may not wrap up PV anti-circumvention probe until August, says ROTH
The US Department of Commerce’s anti-circumvention probe has essentially shut down US procurement of PV modules, and the government is expected to take its full allotment of 150 days to make a ruling, says Philip Shen, managing director of ROTH Capital Partners.
Storing renewables in depleted oil and gas wells
US researchers have proposed the use of hydraulically fractured oil and gas wells to store renewable energy via compressed natural gas, with the levelized cost of storage potentially coming in at $70/MWh and $270/MWh. They said wells could also be used to store other renewable gases such as carbon dioxide or hydrogen in the future.
Low-temperature perovskite solar module with 19.1% efficiency
Researchers have developed a PV module with with an efficiency of 20.72%, based on tin oxide (SnO2) as an electron transport layer, an organometal halide perovskite layer, organic halide salt phenethylammonium iodide (PEAI) as a passivation agent, and Spiro-OMeTAD as the hole transport layer (HTL).
Radiative cooling for PV modules – challenges and prospects
A group of international scientists has investigated the potential use of radiative cooling in PV systems, in a newly published review focusing on challenges and opportunities for the passive cooling technology.
Bosnian Serb republic to introduce net metering for residential PV
Elektroprivreda Republike Srpske (ERS), a utility in the Republic of Srpska – one of the two entities of Bosnia and Herzegovina – will introduce a net-metering scheme for residential PV before the end of this year.
