New grid-scale battery design stacks up for Altech
Western Australian battery technology company Altech Batteries has updated the design of its 1 MWh sodium chloride battery energy storage system, paving the way for the modular units to be stacked three high, allowing for smaller project footprints that conserves valuable land area.
Novel algorithm estimates global maximum power point in partially shaded PV systems
Developed by scientists in India, the global maximum power point (GMPP) technique is based on the voltage and current of strings in a PV array. The research group tested it in computer simulation, as well as through an experimental setup.
Hydrogen-powered vertical takeoff aircraft from Sydney startup backed by ARENA
Sydney startup AMSL Aero has been awarded $5.43 million by ARENA to develop a hydrogen-powered electric aircraft capable of taking off and landing vertically. The startup has previously flown a battery-only prototype, but says adding a hydrogen fuel cell will increase the range to 1000km.
BYD unveils new agrivoltaics module
Chinese module maker BYD is producing a new bifacial monocrystalline panel at its manufacturing facility in Sao Paulo, Brazil. The module has a power output of up to 355 W and a conversion efficiency of 16.33%.
Longi claims 33.9% efficiency for perovskite-silicon tandem solar cell
The US Department of Energy’s National Renewable Energy Laboratory (NREL) has confirmed Longi’s achievement of a world record-breaking efficiency rating of 33.9% for a perovskite-silicon tandem solar cell.
ClearVue to add 82 kW of solar glass to greenhouse in California
ClearVue plans to install clear solar glass on a System USA greenhouse in California, adding 82 kW of power.
Storing renewables with landscaping gravel
Sandia National Laboratories and CSolPower have started researching the use of landscaping gravel as a thermal energy storage medium.
LAVO pivots to new model, offering households renewable ecosystems via subscriptions at no upfront cost
LAVO, which entered the market with its hydrogen battery in 2021, has soft launched a new Energy-as-a-Service model. Partnering with Yingli Solar, LAVO says it can install and maintain solar, battery and EV charging systems at no upfront cost to Australian households, who will then pay off the systems via a 10-year subscription.
Quinbrook introduces energy tracing into portfolio as Australia hesitates on granular certificate scheme
Renewable energy investor and developer Quinbrook has launched software to allow customers to trace both the source and carbon-intensity of their electricity in real-time. The energy-tracing platform comes at an important moment, just as Australia’s government is deciding whether to include time-stamped and granular source information in its formal certificate schemes.
Agrivoltaics and the art of farming under cover
Ground-mounted PV is increasingly being investigated not only as a renewable generator, but as shelter for crops and creatures under fire from climate change. Last week’s All Energy conference handed the mike to some pioneers in the field.
