Australian miner tests vanadium redox flow battery technology
Australian miner IGO is building upon its renewable energy options at its Nova nickel operation after signing an agreement with Perth-based energy storage company VSUN Energy to test a hybrid standalone power system backed by a vanadium redox flow battery.
Redox flow battery with capacity retention of 99.98% per cycle
The battery was fabricated by Chinese scientists with a low-cost electrolyte made of a derivative of TEMPO, which is a well-known electroactive aminoxyl radical used with several applications in chemistry and biochemistry. According to the researchers, the battery shows high redox potential and is crossover-free.
Distribution networks to shrink as safety, reliability of standalone solar improves
Western Australia leads the world in successfully implementing renewables-based generation for far-flung customers. Boundary Power has been widely recognized for its innovations and is ready to repeat its successes with standalone power systems across Australia and the Asia-Pacific.
The Hydrogen Stream: Australia takes the spotlight with 1.7 GW project in Tasmania and new tech to produce hydrogen from rooftop PV
Elsewhere, Portugal’s EDP has unveiled plans to deploy 1.5 GW of green hydrogen capacity and, in Spain, several projects have been announced by Fotowatio Renewable Ventures (FRV), Iberdrola, Solaria Energía and Enagás.
System design for greenhouses relying on PV and ground source heat pump
Proposed by Turkish scientists, the system design consists of combining rooftop PV with a ground source heat pump in a greenhouse used for tomato, cucumber and lettuce cultivation. The solar array operates under net metering and grid electricity is used when PV generation is unable to cover demand. According to their findings, the system payback time ranges from 2.6 to 7 years.
Novel way to calculate levelized cost of hydrogen generated by offgrid PV
French energy giant Engie has developed a transfer function method based on a model used to assess PV plant variability. Its researchers claim that the new approach does not overestimate the levelized cost of hydrogen of an alkaline electrolyzer powered by offgrid solar.
European consortium develops ways to couple heat pumps with solar panels
The Sun Horizon consortium has started to collect performance data on two pilot projects that combine heat pumps with solar systems using hybrid panels on homes in Riga, Latvia. The solution features a heat pump for space heating and domestic hot water and PVT panels to produce power for heating and domestic appliances, with excess power fed to the grid.
Canadian Solar signs deal for 1.5 GW/3 GWh of UK batteries
English clean energy company Windel Energy will develop the projects until they are ready-to-build, with Canadian Solar expected to supply the batteries.
Analyst revises up zero-emission vehicle forecast after bumper year
A report published by BloombergNEF for the COP26 climate change summit has listed global commitments by cities, states, provinces and nations to end the sale of new fossil-fueled vehicles but, with 2035 estimated as the cut-off date for zero-emission roads by mid century, policymakers need to be more ambitious.
Australia’s hottest town now has a battery to store its excess solar
The town of Marble Bar in Western Australia’s remote East Pilbara region is famed for at one time recording 100 consecutive days of temperatures exceeding 37 C. So it’s no wonder the town’s residents have excess solar and nowhere to put it. That is, until now, thanks to the installation of a battery energy storage system beside the town’s centralized solar farm.
