Three companies are swapping out aluminium and glass in favour of plastic to save weight and add flexibility. We look at the pros and cons.

U.K.-based Gravitricity is planning to deploy its gravity-based energy storage solution at a decommissioned coal mine in Czechia. The project is part of a plan to commence a full-scale, 4-8 MW prototype scheme in a disused mine next year.

The record efficiency was obtained thanks to an interlayer placed between the electron-transporting layer and the perovskite layer, which eliminated the need for passivation. The cell was also able to retain around 90% of its initial efficiency after 500 hours under standard illumination.

One year on from its spinoff from SunPower, cell and module maker Maxeon Solar Technologies is looking to supply both “across and through” the solar market segments in the Asia-Pacific region. Chris O’Brien, the vice president of APAC for Maxeon, says that the region is set to grow in importance among PV marketplaces, with opportunities on the home, business and free field.

Queensland government-owned utility Ergon Energy has opened the doors to a new $6 million “world-class” research and development hub designed to accelerate the integration of renewable energy technology including microgrids and standalone power systems into the state’s electricity network.

Australian clean energy investment firm Providence Asset Group will roll out hydrogen-lithium battery technology at its solar farms after partnering with the Commonwealth Bank to fund a portfolio of 10 community-based solar plants in regional Victoria as part of the group’s larger ambitions to develop up to 40 ~5 MW solar farms across the eastern states.

The first commercial application of Australian hydrogen research and development company Star Scientific’s award-winning Hydrogen Energy Release Optimiser technology has been given the green light with the company announcing it has partnered with manufacturing network Central Coast Industry Connect to establish a new industry-led hydrogen cluster on the New South Wales Central Coast.

Australian oil and gas giant Woodside is continuing its exploration of renewable energy, partnering with United States-based concentrated solar power entity Heliogen to build a 5 MW solar thermal demonstration plant in California which is expected to be capable of delivering clean energy with nearly 24/7 availability.

Spanish company Axial Structural is introducing a new type of tracker for agrivoltaic installations. The product can be adapted to various ground conditions and gradients, with programmable to optimise light and shade for different crops in different climates.

Scientists in the United States have developed a method to compare the performance and number of defects in different perovskite cell materials. Based on simulations and work with prototype materials, the group finds that all-inorganic materials have higher potential efficiency than their more widely researched organic-inorganic counterparts.
