...The steam methane reforming process can be coupled with carbon capture and storage technology to cut CO2 emissions but the cost of producing hydrogen carbon capture and storage is about 45% higher. And the cost of CO2 avoidance is also high, at about €70 per ton. This is not financially viable and would require technological breakthroughs in carbon capture and storage to become a sustainable solution.
As an alternative, hydrogen can also be produced by electrolysis, which uses electricity to split water into hydrogen and oxygen, using zero-carbon and low-cost renewable energy.
.. For example, fuel cell vehicles can be charged fully with hydrogen within five minutes for a driving range of 500 kilometers and more, with zero CO2, sulfur dioxide or nitrogen oxide emissions.
