The race to scale up green hydrogen (FT)

… For decades, hydrogen has been hailed as a potentially revolutionary alternative to fossil fuels …

  1. Green hydrogen - Made by using clean electricity from renewable energy technologies to electrolyse water (H2O), separating the hydrogen atom within it from its molecular twin oxygen. Currently very expensive.

  2. Blue hydrogen - Produced using natural gas but with carbon emissions being captured and stored, or reused. Negligible amounts in production due to a lack of capture projects.

  3. Grey hydrogen - This is the most common form of hydrogen production. It comes from natural gas via steam methane reformation but without emissions capture.

  4. Brown hydrogen - The cheapest way to make hydrogen but also the most environmentally damaging due to the use of thermal coal in the production process.

  5. Turquoise hydrogen - Uses a process called methane pyrolysis to produce hydrogen and solid carbon. Not proven at scale. Concerns around methane leakage.

« … car rien ne se crée, ni dans les opérations de l’art, ni dans celles de la nature, et l’on peut poser en principe que, dans toute opération, il y a une égale quantité de matière avant et après l’opération ; que la qualité et la quantité des principes est la même, et qu’il n’y a que des changements, des modifications. »

Antoine-Laurent De Lavoisier 1789, Traité élémentaire de chimie.
