Energy Storage

Alberto Boretti was a senior research professor at Prince Mohammad Bin Fahd University in 2021 when he first started discussing the idea of a hydrogen city in Al Khobar, Saudi Arabia. The New Zealand-based independent tells pv magazine that it is now commercially feasible, as the city’s 200 MW of energy demand would necessitate 1 GW to 1.3 GW of solar and wind capacity, 509 MW to 997 MW of electrolysis capacity, and 145,000 MWh of hydrogen storage capacity.

Contemporary Amperex Technology Co. (CATL) has shown its latest lithium iron phosphate (LFP) battery at an auto show in Beijing. The Chinese company says it has an energy density of 205 Wh per kg, almost 8% higher than the current state of the art for such batteries.

Tequs said its new plug-and-play heat pump can deliver up to 90 C of heat for space heating, air conditioning, and domestic hot water. The new product is available in eight versions with capacity ranging from 17 kW to 268 kW.

The International Energy Agency (IEA) has issued its first report on the importance of battery energy storage technology in the energy transition. It has found that tripling renewable energy capacity by 2030 would require 1,500 GW of battery storage.

Waaree Energies will manufacture and supply 400 MW of bifacial solar PV modules to Gujarat Industries Power Co. Ltd’s (GIPCL) project in Gujarat.

The Korea Institute of Energy Research has developed a solid oxide electrolysis cell stack that uses a special kind of separator plate to ensure proper flow of hydrogen and oxigen after water splitting. Samsung Electro-Mechanics and Bumhan Industries are now cooperating with the research center to improve relevant manufacturing process.

Ohmium International (Ohmium), a green hydrogen company that designs, manufactures and deploys advanced proton exchange membrane (PEM) electrolyzers, has partnered with Tata Projects, an EPC company, to execute green hydrogen projects in India.

Electric three-wheeler (e-3W) sales in India surpassed 580,000 in 2023, compared to 320,000 sold in China.

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have identified a high-energy, high-power hybrid sodium-ion battery capable of charging in just a few seconds. The system integrates anode materials typically used in batteries with cathodes suitable for supercapacitors.

The green hydrogen will be used as combustion fuel in HVOF coating of turbine underwater parts in addition to generating electricity through its 25 kW capacity.
