Distributed Storage

Researchers and investors say they see room for PV investments in Zanzibar, due to the energy needs of many luxury holiday resorts.

Researchers in Australia have compared the technical and financial performances of a hydrogen battery storage system and a lithium-ion battery when coupled with rooftop PV. They evaluated two commercially available systems – LAVO and Tesla Powerwall 2 – and found that the lithium-ion battery provides better financial profits, whereas the hydrogen battery offers more battery lifespan for long duration of energy storage.

Lower costs, better supply chains and steady demand are driving an energy storage boom in the United States, according to a new report from Wood Mackenzie.

Schneider Electric’s EcoStruxure Microgrid Solution can be paired with Mainspring Energy’s Linear Generator to produce and store carbon-free energy for continuous use.

Researchers in South Korea have analyzed the feasibility of using thermoelectric generators in combination with residential solar-assisted ground-source heat pumps and have found that the thermoelectric devices may act as a suitable power source for data loggers and other sensors in a building system.

SolarEdge’s Re-Energize program includes data card upgrades to connect smart home devices and home battery backup.

The first installations featuring the Tesla Powerwall 3 are currently being completed in the United States, with the company promoting a fully integrated solar-plus-storage and electric vehicle (EV) residential system, with big backup power capacity. While the first Powerwall created a new market segment, the latest iteration enters a marketplace in oversupply.

While much of the focus on electric vehicle (EV) charging infrastructure focuses on volume, what about quality? And who is going to maintain a multi-million strong fleet of EV chargers?

Scientists in Korea have built a green hydrogen system prototype that embeds a PV generation unit based on photoanodes made of perosvksite solar cells. The device purportedly achieved a solar-to-hydrogen efficiency of 9.8% for a device with a size of 0.25 cm2, and 8.5% for a system measuring 123.2 cm2.

Australian researchers have designed a new catalyst that has the potential to deliver a new generation of lithium-sulfur batteries that can be charged in less than five minutes, instead of several hours.
