Two government bodies set up to fund the development of renewable energy will have their mandates expanded to fledgling technologies such as carbon capture and storage (CCS), hydrogen production and green steel, under a $1.9 billion package to be announced on Thursday.

Days after outlining a gas strategy for the eastern states, the Morrison government will expand the mandates of the Clean Energy Finance Corporation and the Australian Renewable Energy Agency so they can help fund the development of low-emission technologies beyond wind and solar.
