After a leisurely break over the holiday period, I have returned to my desk to get right back into the analysis of what I think will be a pretty exciting year for the NEM. Connection difficulties, commissioning delays and stubbornly high storage costs point to uncertainty on the supply side, while strong rooftop uptake continues to whittle out daytime operational demand.

The breadth and depth of detail in the GSD2019 (to be released today) reveals any number of important insights into the supply side of the NEM. One theme that stood out for me as I reviewed the data was the set of challenges facing the NEM’s most recent crop of new entrant generators – utility-scale solar farms – as they come to grips with the messy reality of the electricity market.

A new report from Hydrogen Council predicts that the cost of renewable hydrogen production will fall drastically by up to 60% over the coming decade due to the declining costs of renewable electricity generation and the scaling up of electrolyzer manufacturing. Thanks to its optimal renewable resources, Australia will be among the countries most favorably placed to contribute to the development of the hydrogen economy.

UK researchers claim to have proved the viability wearable photovoltaic devices as an integral part of regular clothing. A solar-powered fabric textile was created by embedding micro crystalline silicon solar cells within the fibers of a textile through very thin copper wires. The scientists claim that the novel device can maintain its performance even after 15 domestic machine wash cycles, 25 hand wash cycles, and 6000 abrasion cycles.

This long Australia Day weekend, Australians may be considering what it takes to survive on their continent. One company based in arid Arizona has partnered with ARENA to demonstrate how solar PV can combine with other technologies to solve some of the country’s biggest problems — take a sip of Renewables 2.0. 

Curtin University research that aims to develop a new way of producing, storing and exporting green hydrogen from Australian resources, UNSW Sydney’s efforts to develop novel cathode coating materials towards more durable and powerful energy storage devices and Monash University’s investigation into phase change materials for wind and solar energy storage are among 18 new research collaborations supported by funding through the Australian Research Council.

Energy Minister Angus Taylor has confirmed that Australia is on its way to hit nearly 50% renewables share by 2030, the target deemed economically suicidal by the Coalition during the last election. With no mention of the widely-reported massive drop in renewable energy investment, Taylor hailed 2019 as a new record year for renewables in Australia.

The Australian Energy Regulator (AER) has given its tick of approval to the proposed $1.53 billion electricity interconnector between Robertstown in South Australia and Wagga Wagga in New South Wales. The new transmission line holds the promise of reducing power bills in both states by unlocking gigawatts of planned renewable energy projects in its close proximity.

Queensland’s Darling Downs region is set for its second large-scale solar project to gain grid connection in a matter of months as Risen Energy’s 100 MW Yarranlea Solar Farm connects to the grid for its staging procedures.

The 25MW/52MWh battery at the Lake Bonney wind farm is in the final stages of testing and close to full commercial operation. Once operational, the big Tesla battery will supply the electric car maker’s Australia EV supercharger network with renewable electricity.
