Redflow announces integration with US inverter company
Australian redox-flow battery specialist Redflow has upped the ante on its plans to expand into the US market, announcing that it has completed testing to pave the way for its battery energy storage system to be used in conjunction with hybrid inverters manufactured by US solar engineering company Sol-Ark.
Solar panels and sheep grazing
Two Australian farmers say their solar panels increased grazing quality during droughts over a four-year period, aligning with research suggesting that solar panel microclimates might increase water retention and grass production.
The Hydrogen Stream: World’s first hydrogen-powered towboat
Shipbuilder Hermann Barthel has developed the world’s first push boat to combine battery-electric propulsion with hydrogen and fuel cell technology. Iberdrola and Fertiberia, meanwhile, have commissioned Europe’s largest green hydrogen production plant.
PVT-biomass system for space heating in small homes
A US-Chinese research group has developed a hybrid system proposal based on photovoltaic-thermal (PVT) modules, a heat pump, a backup electric boiler, and biomass generating units. They say it could be used as space heating in a single-floor home.
Storing hydropower via regenerative braking in electric trucks
An international research team has proposed the use of water from high-altitude rivers and regenerative braking in electric trucks to store electricity for reuse in power networks, or for transport purposes.
Transgrid builds high-voltage interconnector to link Australian states
Transgrid, the transmission network owner in the Australian state of New South Wales, has started building its section of the AUD 2.3 billion ($1.64 billion) Project EnergyConnect. The high-voltage electricity transmission interconnector will link power grids across three states, unlocking gigawatts of planned renewables.
Tesla rallies Powerwall owners to show how they can help Texas grid
In Texas, where batteries cannot send power to the grid, Tesla has filed a request for a rule change and has called on Powerwall owners to form a virtual power plant.
Floating solar, tidal energy plant goes online in China
CHN Energy has linked a 100 MW floating PV plant to an existing 4.1 MW tidal energy system in China’s Zhejiang province. The tidal power station was commissioned in 1980 and is the fourth-largest system of its kind in the world.
Photovoltaics for refrigeration
Scientists in Saudi Arabia looked at the potential of different solar technologies to meet energy demand for cooling systems. They found that PV is the best cost-effective option, especially for compression refrigeration cycles in hot climates.
New solar module for pavement applications
Hungary’s Platio Solar has developed a new PV module line featuring monocrystalline and polycrystalline cells with clear or opal glass.
