The Energy Minister Josh Frydenberg has announced legislation to allow the Clean Energy Finance Corporation to fund coal-fired power stations using Carbon Capture and Storage (CCS), often called “clean coal”. Although there has been plenty of criticism, this is actually a Good Thing.
If it worked at low cost, CCS would solve a lot of problems, particularly for Australia. We could burn coal, and store the resulting carbon dioxide somewhere else, fixing much of the climate change problem without changing anything else. The ease of this (hypothetical) solution is why CCS plays a big role in lots of climate change scenarios.
Unfortunately, cost-effective CCS doesn’t exist, and isn’t likely to. So, barring some great new discovery, the change in CEFC rules is purely symbolic.
What makes the announcement a Good Thing is that avoids the “bait and switch” used by Frydenberg and others in the past, where clean coal is described in terms of CCS, then shifted to included “High Efficiency, Low Emissions” (HELE) coal plants. This term refers to the fact that plants constructed today are indeed more efficient, and therefore have lower emissions per unit of electricity, than those built thirty years ago. But they are still far worse than gas-fired plants let alone renewables or (if it could be made to work) CCS.
