The Andrews Labor government has been returned in Victoria. It must now reckon with two particularly crucial challenges: runaway climate change and wartime-scale energy costs.
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.
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.
The worst effects of the pandemic may have passed, but supply chain disruptions continue to be felt across the world. The effects of the war in Ukraine are also evident to all of us in our daily lives, from commodities to energy, food supply chains and beyond. The disruption in the battery energy storage system (BESS) supply chain is no different, writes Cormac O’Laoire, senior manager of market intelligence at Clean Energy Associates. Indeed, as the cost of raw materials such as lithium climb, battery prices are being driven materially higher, on some accounts by 20% to 30%, rendering some projects uneconomical.
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.’
