Hydrogen, batteries, green steel, carbon capture and storage, and soil carbon have been identified by the federal government as the five top- priority, low-emission technologies it will aim to develop over the next decade.

The long-awaited technology road map, to be released on Tuesday by Energy Minister Angus Taylor, ranks energy efficiency, and electric and hydrogen vehicle recharging infrastructure as second level "emerging" technologies while nuclear power is delegated to a third-order "watching brief'' priority.

Hydrogen, for example, will be deemed competitive when it can be produced for $2 a kilogram or less. It could then be used as a mainstream fuel for generating electricity to back up renewables, heavy transport and industrial applications such as producing ammonia or smelting steel.

A leaked draft of the road map, obtained by The Australian Financial Review, says producing hydrogen by using gas or coal to electrolyse water, and then sequestering the emissions using carbon capture and storage, will be the "lowest cost clean production method in the near term, although other renewable production methods will also come down in cost as clean hydrogen demand grows''.

Mr Taylor, who will launch the road map with a speech on Tuesday to the National Press Club, said there would be annual updates to Parliament on the progress towards developing the five priority technologies

Green steel and aluminium, which will use hydrogen or some other clean fuel for smelting, needs to cost less than $900 a tonne for steel and $2700 for aluminium.
CCS technology, which now costs an uneconomic $30 per tonne, will need to be $20 a tonne to be commercially viable.
