Technology and R&D

An Australian software startup that aims to make it easier for energy providers and solar installers to assess the feasibility of commercial-scale renewable energy projects will now pursue global expansion plans after completing a seed funding round.

The 5 kWh battery solution uses Ecoflow’s PV-coupling technology that reportedly ensures an easy connection to existing solar arrays. The new product features an output voltage range of 150-800 V.

The solar-powered Stella Terra test car from The Netherlands’ Eindhoven University has just completed a 1,000 kilometre test drive from northern Morocco to the Sahara. In Australia, the solar car racing team from the University of New South Wales says the real challenge is to find new ways to push the boundaries of solar car races.

Solax claims its new hybrid inverters can oversize PV systems by 200%, making them an ideal solution for commercial rooftop installations. There are five versions, featuring rated power outputs ranging from 15 kW to 30 kW.

Falling ceramic particles less than half a millimetre in size have been used by Australia’s national science agency, the CSIRO, to store energy in a concentrated solar thermal system. The team recently achieved a temperature of 803°C using the process at its pilot plant in NSW.

RMIT University in Australia has developed new software that integrates product, regulation, technical, economic, and construction data. It helps architects and engineers to estimate the cost of building-integrated photovoltaics (BIPV) during the conceptual design phase.

Diesel trains have been retrofitted with batteries and are now running from Adelaide stations, in the latest of a spate of sustainable transport trials in the South Australian capital. This includes trials with fully electric trains and the beginning of trials with hydrogen-powered and pure electric buses.

Massachusetts Institute of Technology (MIT) scientists have developed a train-like concentrated solar power (CSP) system for hydrogen production, with plans to build a prototype in the coming year. They say that this innovative system can capture up to 40% of the sun’s heat to produce environmentally friendly hydrogen fuel.

Researchers at Victoria’s Monash University have developed a new lithium-sulphur battery design they claim requires less lithium, has more energy per unit volume, lasts longer and can be produced for half the price of the dominant lithium-ion technology.

Scientists in the United States have achieved a breakthrough in PV cell tech by creating a 24 cm2 perovskite-silicon tandem solar cell. It positions a lithium fluoride interlayer between a hole transport layer and the perovskite absorber to reduce shunting losses.
