The Morrison government will put another $50 million into carbon capture and storage technology, following more than $1 billion in taxpayer subsidies and investment from the fossil fuel sector since the early 2000s.

This is part of the government's $1.9 billion "new technologies" package, aimed at funding fledgling projects such as making gas-fired hydrogen fuel – a process that still needs CCS as the process releases carbon dioxide that has to be buried if the hydrogen is to pass as clean energy.
