Nice post Speaking of Twiggy's clean energy, this appeared in the AFR this morning - Gas power enters Forrest’s renewable energy empire

Snippet below:

Squadron has 1.1 gigawatts of renewable energy generation in operation and a development pipeline of wind and solar of 20 gigawatts. It is also developing battery storage, which is likely to include large-scale lithium-ion batteries and “flow” batteries that use a technology that may be better at delivering energy over a longer period.

However, Squadron has found that even with battery storage, “firming” is required to provide the reliable power that businesses and industrial customers want. It decided that pumped hydro was too risky from an economic point of view. “We look around and say, ‘well, what’s the appropriate fuel at the moment for that firming generation’, and the reality is between now and the end of the decade it’s going to be gas,” Mr Willoughby said, noting that on an annual basis, gas power would only provide 5 per cent to 10 per cent of Squadron’s electricity mix.

“We don’t think it’s a long-term solution – we think the green hydrogen will be the firming fuel that powers the renewable transition long term – but we don’t want the transition to stall until green hydrogen is available, we’re going to do both things at the same time.”
