An obvious problem with hydrogen is the likely high cost of production. Another one is the vast amounts of renewables needed to make the plan work, or if coal or gas is used, the high cost and doubtful viability of large-scale carbon capture.
The federal government’s top scientist Alan Finkel says Australia could slash global carbon emissions and create a multi-billion dollar export industry by developing hydrogen as an everyday energy source to replace fossil fuels used in vehicles, homes and industry.
A major climate report on Monday identified hydrogen, which can be produced with virtually no emissions, as among fuel options that must be developed if the planet is stay below the critical 1.5 degrees warming threshold and avoid the worst climate change disasters.
The report by the UN’s climate science body, the Intergovernmental Panel on Climate Change, called for a coal phase-out by 2050 and predicted a substantial decline in the use of natural gas – two export industries upon which Australia is heavily reliant.
