Researchers at Monash University have managed to find a way past one of the few remaining roadblocks to producing industrial quantities of hydrogen gas through electrolysis via solar energy.

Sydney’s iconic Shelley Beach is now home to two solar-powered smart bins, the bins are capable of compacting waste to reduce collections, thereby cutting council emissions.

Scientists led by the Technical University of Denmark have begun a project to design solar cells that can be produced in different colors with minimal effect on performance, making them suitable for building-integrated and other applications with aesthetic considerations.

The devices, developed by a European research team, are said to have twice the energy density of conventional aluminum devices. The scientists used a cathode made of anthraquinone, instead of one based on graphene, increasing energy density.

As part of a broader push to develop a domestic hydrogen industry, the Australian Renewable Energy Agency (ARENA) is providing $2.9 million for two studies into using solar and wind-powered hydrogen for ammonia. Both project are located in Queensland and presently use natural gas as feedstock.

Australia’s chief scientist Dr Alan Finkel continues to voice his support for some modicum of Carbon Capture and Storage (CCS) in Australia’s hydrogen future, providing a lifeline to fossil fuel producers. While Finkel’s argument holds some water, it holds nowhere near enough water to produce a hydrogen economy. 

The Australian Space Agency (ASA) has joined the next generation, or rather this generation, space race, between the U.S. and China. A $150 million investment from the Morrison Government into the ASA will see Australia partner with NASA on its next sustainable exploratory missions.

Despite being such a sunkissed country, Australia is still lagging behind in the race to embrace solar power. While solar panels adorn hundreds of thousands of rooftops throughout the nation, we have not yet seen the logical next step: buildings with solar photovoltaic cells as an integral part of their structure.

Why is electric aviation still up in the air? Or rather, why isn’t it up in the air? We have Teslas on our roads, Melbourne’s trams are powered by solar, and trains are connected to the grid already, but why is electric aviation lagging behind?

Research has found even short-lived, 10 to 15-year solar panels could provide enough return for bankable projects. The researchers believe panel costs, coupled with an industry mindset now fixed on the final solar energy price rather than costs per kilowatt installed, may open opportunities for PV products currently snubbed because of a short lifecycle.
