Four ways heat pumps can assist the world’s energy transition
From using heat pumps in decommissioned power plants, to utilizing them for storage and carbon capture – scientists from China have listed the ways in which heat pumps can help the global energy transition move forward. They showed that their potential is beyond heat electrification.
Japanese scientists develop high energy density, cobalt-free lithium-ion battery
The new cobalt-free battery yields about 60% greater energy density than conventional lithium-ion batteries for an equivalent weight and volume and sustains unprecedented 1,000 cycles.
US draft rules may disqualify Australian critical minerals from IRA subsidies
A number of Australian critical mineral producers will likely be ineligible for US Inflation Reduction Act (IRA) subsidies, as the US government has published draft rules forbidding access to enterprises with stakes held by Chinese investors.
New model to predict defrost cycles, behavior of air-sourced heat pumps in cold weather
UK-based researchers have developed a novel method to estimate the amount of defrost cycles a heat pump will experience in the winter and how much energy it would require to implement the cycles. The results of their simulation showed a strong relationship between the number of defrost cycles and the ambient temperature.
Tesla Cybertruck can power homes
Tesla’s new trucks offer 11.5 kW of power output to homes, and 9.6 kW of output via five plugs.
California’s lithium reserves could power 375 million EV batteries, say researchers
The Lawrence Berkeley National Laboratory has prepared a report, funded by the US Department of Energy, to thoroughly quantify the amount of lithium in an underground reserve in the Salton Sea, California.
Toshiba develops lithium-ion battery prototype for high-voltage applications
Toshiba has developed a 1.5 Ah lithium-ion battery prototype with a voltage of more than 3 V. The device retains its initial efficiency for over 6,000 charge/discharge cycles and enables rapid charging to 80% of capacity within just five minutes.
Daikin unveils series of residential air-to-air heat pumps
Daikin has released a line of residential air-to-air heat pumps, using difluoromethane (R32) as the refrigerant, with outdoor unit dimensions of 662 mm x 442 mm x 1022 mm. The output ranges from 2.5 kW to 3.5 kW, and the seasonal coefficient of performance (SCOP) is between 4.85 and 5.17.
Scientists unveil tool to calculate feed-in, net metering tariffs in residential PV linked to storage
Developed by researchers in China, the novel calculator uses current and voltage sensors, a Raspberry Pi, and an algorithm for fuzzy logic to determine variations in frequency and demand. The tool sends Email notifications with the tariff values to the PV system owners.
CATL: Staying on top of the battery game
For the seventh year in the row, China-based Contemporary Amperex Technology Co. (CATL) looks set to claim the title of the world’s biggest battery maker. There are a number of reasons why it continues to maintain its lead in the electric vehicle (EV) and battery energy storage system (BESS) markets..
