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.

Cordier, a winery in Bordeaux, France, is building solar carports at two of its facilities in southern France. The two PV arrays will be tied to 20 EV charging stations.

The Hungarian government has earmarked HUF 62 billion ($169 million) for grid-scale energy storage projects in a bid to facilitate further deployment of renewable energy sources.

Chinese inverter manufacturer Sungrow shipped 130 GW of inverters last year, reaching a profit of $1.3 billion.

Sales of electric three-wheelers (e-3W) in India surpassed 580,000 units in 2023, compared to 320,000 vehicles sold in China, according to the International Energy Agency (IEA).

Aurora Energy Research says it has recorded a sharp increase in green hydrogen projects, with 90% of them in early phases of development, while E.ON says that Germany’s hydrogen ramp-up is stuck due to an investment backlog.

Researchers in China have designed a two-stage, solar-assisted thermochemical heat pump system that uses caustic soda and water as a working pair. The system is reportedly able to achieve an energy storage density of 363 kWh/m3 and is considered by its creators an ideal solution for residential buildings with limited space.

An international research team has proposed using iron oxide and copper oxide to lower photovoltaic-thermal (PVT) solar module temperature. Their analysis showed that the two compounds were able to lower the panels’ operating temperature by 23.49% and 34.58% respectively.

Baud Resources, a clean-tech startup, has developed a gravity energy storage mechanism that uses locally available materials such as sand and industrial waste as its payload. The company is building a 100 MWh pilot plant that will reportedly offer a levelized cost of storage of around INR 2.5 ($0.03)/kWh.
