Technology and R&D

Vaulta, an Australian battery tech company, has developed its first dedicated residential battery. The small-scale energy storage system can purportedly operate for 4,000 cycles, with an 80% depth of discharge.

Dutch gas supplier Gasunie says several market participants have reserved capacity in the first salt cavern for large-scale hydrogen storage near the Dutch city of Groningen. According to current planning, the first cavern will be operational by 2028.

The SeaVolt consortium says it will launch an offshore floating PV demonstrator off the Belgian port of Ostend. The main companies – Tractebel, DEME, Equans and Jan De Nul – say the anchored floating array will collect data for at least a year to scale up the tech.

Enfoil is developing a CIGS thin film custom manufacturing business, targeting building-integrated PV applications, such as powering sensors or track & trace sub-systems in trucks. The company is a spinoff of Hasselt University and imec, the Belgian research institute.

The novel heat pump, developed by a research group in Israel, consists of a loudspeaker, a resonator, and a thermoacoustic core placed inside the resonator. The core includes a cold heat exchanger, a stack, and an ambient heat exchanger.

CVE, a French developer, has deployed a solar plant based on PV modules ballasted on the ground. The installation will cover nearly 10% of the overall consumption of an industrial site in Châtillon-sur-Chalaronne, France.

Scientists from India conceived a new system for crop growth in remote areas with no connection to the power grid. It consists of a PV panel, add-on module hardware (AOMH), a battery, step-down DC-DC converters, system power devices, automation, and sensor elements. For climate control, it also comprises a water pump, a ventilation fan for CO2 assimilation, sprinkler foggers, and drop irrigation solenoids.

Burgerland Energie has deployed a redox flow storage battery from German battery manufacturer CMBlu in the immediate vicinity of a PV-wind power hybrid power plant.

Scientists in Ireland investigated the effect of shunt resistance on a PV cell’s electrical performance. The group says its finding could potentially lead to the development of models for early detection of various forms of cell degradation, allowing for intervention to repair or replace components before major power losses occur.

A grid-connected community battery has gone live in Sydney, Australia, with New South Wales electricity distributor Endeavour Energy testing the tech to maximize the benefits of rooftop solar.
