Mitsubishi Power Americas will supply batteries for the development of three battery energy storage systems in the southeast US. The three hybrid projects are being developed by Origis Energy as part of 1.5 GW of operational and contracted assets in the region.

Researchers from the United Kingdom, the United States and Australia have reportedly developed a perovskite solar cell with comparable stability and durability to commercial silicon PV cells. They used a high-temperature processing method with dimethylammonium chloride to control the intermediate phases of perovskite crystallization.

US-based Emporia Energy has developed a home battery system with an inverter and transformer. The lithium iron phosphate (LFP) battery has a storage capacity of 8.2 kWh, and up to six modules can be combined for up to 49 kWh of energy storage. The inverters come in 7.6 kW or 9.6 kW versions.

This year has witnessed upheaval in the global energy system as inflation, geopolitical conflict, and the reality of a changing climate continue to drive the transition to cleaner energy. Next year, these trends are likely to continue and accelerate as renewable energy adoption continues to grow and the inextricable link between energy security and national security is increasingly recognized. Alan Greenshields, of US-based iron-salt flow battery maker ESS Inc, offers four predictions for 2023.

EODev will start delivering hydrogen generators by the end of 2024 to countries in the West and the Middle East, with a focus on regions with public incentive policies. German companies, meanwhile, have agreed to convert a gas pipeline network into a hydrogen pipeline network.

A team in the US will create a pollinator habitat under a 160 MW utility-scale solar project and measure changes in energy, soil carbon, and management costs at the site.

The California Public Utilities Commission has approved Net Energy Metering 3.0 and has slashed payments to send rooftop solar electricity to the grid. New rooftop solar projects are now considered uneconomical without attached batteries.

Johnson Controls has fabricated an air-source heat pump prototype for locations with temperatures below -29 C. Its York YZV and York HMH7 cold climate heat pumps can already operate in -15 C conditions.

Canadian manufacturer Sparq has unveiled a three-phase microinverter for on-grid and off-grid solar water pumps. It has a peak efficiency of 97.5% and a nominal maximum power point tracking (MPPT) efficiency of 99.8%.

US researchers have proposed the use of solar inverters in utility-scale solar assets to replace expensive voltage compensators, in order to provide voltage support at night. They said reactive power from PV inverters could be significantly cheaper and suggested the introduction of incentives to convince PV plant owners.
