Opinion & Analysis

The idea of capturing solar power in space for use as energy on Earth is not new but the race for space-based solar power is heating up and global superpowers China and the United States are leading the way.

Cornwall Insight Australia energy consultant Con Dimitrakakis explores how “clean” the hydrogen produced in Australia by a grid-connected electrolyser could be, depending on its location and change in variable renewable energy penetration into the grid.

In eight years, Australia wants to be four-fifths powered by renewables. Solar and wind investment is pouring in. But to firm the renewables and overcome the intermittency, we need overnight energy storage. That’s why there’s so much interest in pumped hydro.

It has been an interesting year for Australian energy markets, facing unprecedented high energy prices, coal outages, and market suspension. In this Chart of the Week, we investigate the impact a battery energy storage system would have made during FY 2022.

Economist Ross Garnaut’s latest book, the Superpower Transformation, is promoted as a “practical plan” to put the vision of in his earlier Superpower into effect. Clive Hamilton, Professor of Public Ethics at Charles Sturt University, questions if the vision is premised on an imperfect logic.

As uplifting as Australia’s climate turn around is, SMA Australia’s Joshua Birmingham says it would be “naive” to ignore the fact that this rapid growth will present challenges for the industry, with demand potentially outstripping supply in many key areas of the renewable energy value chain. 

While not one of the big five-year-cycle COPs like Paris or Glasgow, COP27 is still hugely important, write Wood Mackenzie analysts. The fallout from the conflict in Ukraine has tilted the precarious balance of the energy trilemma – sustainability; affordability; security – towards the latter. But despite this temporary setback, some progress should still be possible.

There is almost a daily announcement about a major green hydrogen project being built somewhere in the world. Hydrogen and ammonia can be made from fossil fuels but also from renewable energy and water using an electrolyser producing zero carbon emissions. It is critically important that we can tell when it is zero emissions and prevent ‘greenwashing.’

Director of the Australian Solar Thermal Research Institute, Dominic Zaal, offers a deep dive into the capabilities of concentrated solar thermal technology, including what has been proven by global projects so far and how the all important Power Purchasing Agreements stack up.

Former Tindo Solar CEO, Shayne Jaenisch, outlines how Australia’s renewables industry can avoid forced labour, cut waste, secure its supply chains and create a domestic manufacturing industry.
