Removal of any distortionary regulation and taxes will create the foundation for large reductions in emissions. However, the dependence on intermittent power generation for a large proportion of the energy supply will require economic incentives to make the final transition to the carbon neutral emissions target. The scenario analysis suggests that hydrogen fuel cells could be a cost-efficient solution. However, hydrogen production has a very low efficiency, which does not correlate well with an energy system that relies on relatively costly wind power.
