Ann: Redflow enters Voluntary Administration, page-141

Disagree with your conclusion.

The demise of RFX is down to poor management, an inability to solve the tech problems they were having, and the weight of warranty costs, all leading to a loss of confidence in the company as a whole. The loss of one company that was developing an alternative battery chemistry does not prove that the world cannot run on renewables - there are multiple alternative chemistries out there (sodium ion being the obvious one; there are others) under various stages of development, and batteries are only one way to solve the storage problem.

We're learning how to solve the problems associated with a high-renewable grid, and each stage builds upon the previous. Early stages were just tossing in small amounts of renewables, and the grid could cope with that. We're now at the point where we need to have some short-term buffers to help with grid inertia and similar; Hornsdale proved how well lithium can do that job. The challenges increase as the percentage of renewables grows, yes; but so does our knowledge of how to solve those challenges.

The grid wasn't built in a day. In the same way, the renewables transition won't happen immediately.
