Energy Storage

Scientists in Poland have developed a compressed air energy storage technology using a thermal energy storage (TES) system built into a disused mine shaft. The system works without external heat sources, and utilizes an air compressor, a compressed air reservoir with a built-in thermal energy storage system, and an air expander.

Researchers in Sweden have created a thermal energy storage system relying on a dynamic air mass flow rate that is applied during both charge and discharge processes. It achieved a maximum thermal efficiency of around 70%.

An international research team has developed a new way to evaluate the economic value of energy storage technologies. They went beyond pure cost assumptions to consider the benefits that such technologies could bring to energy systems.

The use of waste heat from hydrogen production in district heating could increase the attractiveness of green hydrogen, according to new research from Sweden.

Battery storage is key to Equinor’s strategy of supporting its portfolio of offshore wind and upstream oil and gas, as well as future opportunities in the hydrogen and renewables space.

GlobalData has predicted that the global electrolyzer market will hit 8.52 GW by 2026. BP and Thyssenkrupp have agreed to cooperate on the use of hydrogen in the steel sector, while electrolyzer supplier Nel Hydrogen has secured orders in Australia and Denmark.

The heat pump markets with the highest growth in Europe last year were Poland, Ireland, Italy, Slovakia, Norway, France, and Germany.

Yalong Hydropower is building a 1 GW solar park that will be connected to an operational 3 GW hydropower facility on the Yalong River in southwestern China.

Ion Storage System’s $30 million capital raising will go toward scaling up its solid-state battery cell production facility in the US state of Maryland, with aims to produce 10 MWh per year by the end of 2023, for a range of applications.

India’s AmpereHour Energy has released MoviGEN, a new lithium-ion-based, mobile energy storage system. It is scalable and can provide clean energy for applications such as on-demand EV charging, remote construction sites, and large-scale outdoor events.
