Virtual power plant to trade grid-stability services in New Zealand
New Zealand’s solarZero says it aims to provide fast, sustained reserves with its virtual power plant (VPP) of 10,000 household battery systems. Meridian Energy, meanwhile, has secured approval for a 100 MW battery energy storage system – the country’s largest such system to date.
Neighborhood battery plan to maximize solar benefits in Australia
The government of the Australian state of Victoria has unveiled an ambitious plan to install 100 battery energy storage systems by the end of 2026, as part of a broader strategy to support the rollout of more rooftop solar.
New mobile lithium-ion batteries for utility-scale market
US-based Nomad Transportable Power Systems (NOMAD) has started offering plug-and-play, utility-scale mobile energy storage systems. There are three versions – 2 MWh, 1.3 MWh, and 660 kWh – with a patent-pending docking platform.
Hydrogen-producing rooftop solar panels nearing commercialization
KU Leuven researchers have developed rooftop panels that capture both solar power and water from the air. Like traditional PV modules, hydrogen panels are also connected, but via gas tubes instead of electric cables. The researchers are now preparing to bring the tech to the mass market via a spinoff company.
Rooftop-mounted microgrid combines wind, solar, storage
Hover’s first 36 kW installation survived the recent Hurricane Ian storm system that ravaged southwestern Florida.
Simpliphi presents integrated storage solution for rooftop PV
Simpliphi, a US-based storage system provider, said its new storage system includes a 4.9 kWh battery and a 6 kW inverter. The solution can be scaled up to 358.8 kWh of storage capacity.
PV-powered thermoelectric cooling for air conditioning in buildings
Scientists have proposed a way to combine thermoelectric modules (TEMs) with rooftop PV to support heating, ventilation and air conditioning in buildings. They designed a wall-integrated TEM to heat and cool adjacent rooms.
New polymer-based battery electrodes with high stability
UK researchers have developed organic electrode materials to integrate redox-active organic molecules into long-chain polymers. The new electrodes exhibit better cycling performance in lithium-ion batteries, with no apparent capacity decay over more than a thousand charge-discharge cycles.
Air-source heat pump for harsh, cold climates
Carrier will soon begin field tests for a prototype air-source heat pump for cold climates. It is designed to provide high-efficiency heating performance in harsh climates with temperatures equal or below negative 29 degrees Celsius, while being grid-interactive. The US-based heating tech specialist expects to commercialize the solution by 2024.
Novel redox flow battery paves way for low-cost storage
US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.
