ICL team assesses relative costs of carbon mitigation for 12 H2 production paths; trade-off between cost and level of decarbonization

Green Car Congress

A team at Imperial College London has examined the relative costs of carbon mitigation from a lifecycle perspective for 12 different hydrogen production techniques using fossil fuels, nuclear energy and renewable sources. Their results show a trade-off between the cost of mitigation and the proportion of decarbonization achieved.
