Energy Storage

Finnish researchers have studied different scenarios to convert a Nordic oil-heated townhouse into a carbon-neutral building. They dimensioned an off-grid PV-powered heat pump system using waste heat recovery from a hydrogen storage system and calculated its life-cycle cost. They concluded that the solution is less profitable than grid-connected systems.

Romania-based startup Photovoltaic Windows has developed an off-grid domestic hot water system powered by cadmium telluride (CdTe) photovoltaic semi-transparent glasses. It claims a 0.7 kW pilot installation on an apartment balcony in Bucharest resulted in annual savings of €1,100 ($1,202).

EirGrid assigned 7.2 GW of capacity in its latest auction, with 5.4 GW to come from gas power plants. The auction clearing price reached €83.050 ($90.554)/MW per year.

Daikin has started building its first heat pump factory in Lodz, Poland. The Japanese heating manufacturer will invest €300 million ($327.2 million) in the new facility, which is expected to start operations in July 2024.

IndiGrid has commissioned a pilot project featuring a solar panel bank coupled with a battery energy storage system (BESS), at its Dhule substation in the Indian state of Maharashtra.

Public Power Corp. (PPC), Greece’s state-owned utility, has won a tender to build a solar-plus-storage project on the Greek island of Astypalaia.

Scientists in South Korea have developed a highly soluble, stable organic redox-active molecule for use in aqueous redox flow batteries. The newly developed naphthalene diimide (NDI) molecule offered higher storage capacity than existing vanadium devices.

Stanford University researchers have created a model to assess how much compressed air storage capacity might be needed for the deep decarbonization of power systems, while compensating for the variability of wind and solar-based power systems. They applied the model to California’s energy system and found that compressed air could be very competitive on a dollars-per-kilowatt-hour basis.

Netherlands-based One Solution says its new FlexTherm Eco battery can be used in combination with rooftop PV systems and residential photovoltaic-thermal installations. It consists of a thermal charging station that converts power directly into heat and stores it for the provision of hot water.

San Miguel, which is now behind on its original plan to deliver a 1 GW/1 GWh fleet of battery energy storage systems (BESS) by the end of 2022, continues to roll out big batteries across 32 sites in the Philippines, in order to integrate up to 5 GW of renewables into the island nation’s grid.
