The Hydrogen Illusion (2022) is a self-published book by Samuel Furfari, a retired chemical engineer who worked for 36 years in energy policy at the European Commission. Hydrogen has been brought to the forefront of environmental policy in recent years as the EU and other Western economies are allocating billions of euros and dollars towards hydrogen production. Furfari argues that this is a mistake, and that hydrogen has little potential as an energy form, primarily as it requires so much energy in order to be produced. While at times technical and difficult to follow, The Hydrogen Illusion is a valuable contribution to the ongoing debate about how Western economies can combine economic and environmental development.
