The growing potential of green hydrogen

Published: 05/09/2017

Most hydrogen produced today is used in the petrochemical sector and for manufacturing fertilizers. 99% of it comes from fossil fuel reforming as this has been the most economical pathway. This does not have any real climate benefits, since CO2 is emitted in the process. However, a scalable and potentially low greenhouse gas (GHG) emitting alternative is available through water electrolysis. Such “green hydrogen” could have numerous applications ranging from industrial feedstock to fuel cell vehicles (FCVs) and energy storage. 

In an article for Energy Post, Jan Cihlar of Ecofys, a Navigant company, investigated the potential for green hydrogen. He finds that hydrogen could still become a key enabler of the low carbon transition if it is produced with renewable electricity and enables cost reductions in some transport and industry applications.
