Test bench for aboveground compressed air energy storage systems
Researchers in Canada have created an experimental workbench for aboveground compressed air energy storage. Experimental data calibration reportedly ensured model accuracy with a mean absolute percentage error below 4.0%.
The Hydrogen Stream: Statkraft advances green H2 plans in Germany
Statkraft says it is progressing with its 200 MW electrolysis plant in Germany, while Neste says it will not invest in its 120 MW electrolyzer project in Finland.
Australia has 7.8 GW of utility-scale batteries under construction
The volume of large-scale battery energy storage projects under construction in Australia passed that of solar and wind projects combined in 2023 and the trend has intensified this year, with batteries attracting federal support. As coal-fired power plants are shuttered, developers and suppliers are enjoying a battery bonanza.
Mobile PV-powered EV charging stations for commercial, industrial sites
United Kingdom-based 3ti Energy Hubs has launched a portable electric vehicle charging station for 12 cars that it delivers to commercial and industrial sites where demand exceeds supply.
China’s GNE develops lithium-sulfur battery with energy density of 700Wh/kg
The energy density of the newly developed lithium-sulfur prototype far exceeds the one of common lithium -ion batteries.
Climate data-based methodology for residential air-source heat pump sizing
A European research team proposed a new air-source heat pump sizing approach that utilizes long-term climate data and adjusts system operation based on actual local climate conditions. The sizing algorithm incorporates peak heat demand, unitary final energy demand, and seasonal heat demand across different house sizes.
The Hydrogen Stream: More H2 projects put on hold
Repsol has told pv magazine that it has frozen 90% of Spain’s hydrogen projects nearing final investment decisions, while Statkraft has confirmed that it has revised its plans for its hydrogen project in Norway.
Apartment battery systems attractive after São Paulo storm blackout
Solar-plus-storage systems are attracting homes and businesses to guarantee energy supply and avoid losses in emergencies. Brazilian solar trade body Absolar estimates battery prices have fallen around 90% over 15 years.
The Hydrogen Stream: US researchers explore trapped geologic hydrogen
US researchers have started studying hydrogen formation in the Midcontinent Rift in the United States, while Dutch scientists have discovered that hydrogen emissions from industrial complexes are higher than previously estimated.
BASF receives funding for world’s largest industrial heat pump
The German government has awarded a €310 million ($336 million) funding package to chemical manufacturer BASF for the construction of an industrial heat pump with a capacity of up to 500,000 metric tons of steam per year. It will use waste heat from steam crackers for CO2-free stream production.
