Grids & Integration

SNCF Réseau and the National Institute for Solar Energy (INES) in France have agreed to jointly develop renewables projects. They aim to build PV systems that can supply continuous power at voltages of 3 kV, 6 kV, and 9 kV, while optimizing installation costs – particularly with regard to cables, operations, and maintenance.

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.

Growatt’s new APX HV cobalt-free lithium iron phosphate (LFP) battery has a storage capacity of 5 kWh and a nominal voltage of 650 V. It can be scaled up to six battery modules, for a maximum capacity of 30 kWh, or 60 kWh in parallel. It comes with a 10-year warranty.

The Australian government has announced a $117.5 million (AUD $176 million) funding injection which it expects will unleash over $2 billion of investment in advanced battery technology, delivering a step change in grid-forming capability.

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.

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.

Meteo for Energy offers meteorological prediction and energy production models for photovoltaic, solar thermal, and wind power generation. The new model applies “deep learning” to images from the Meteosat satellite.

Italian grid operator Terna and its Tunisian counterpart, Steg, have secured €307 million ($327 million) to invest in an €850 million subsea cable link between Partanna, Sicily, and Cape Bon, Tunisia.

Acciona Energia is setting up its first V2G network in Spain, ADS-TEC has unveiled a battery-based, all-in-one system with up to 300 kW of charging power, and Volkswagen is looking for a location for its first battery cell factory in North America.

Pacific Northwest National Lab (PNNL) researchers have developed a new framework to compensate energy storage as a dual-use asset.
