About green hydrogen

Green hydrogen is a versatile tool to phase out fossil fuels.

Well-established chemical and industrial processes use around 100 million tons per year of hydrogen produced using fossil fuels through steam methane reforming or coal gasification. In 2021, ~94 million tons of hydrogen were produced, emitting ~900 million tons of carbon dioxide (~2% of global amounts).

Green hydrogen – hydrogen produced by splitting water using renewable energy without producing carbon dioxide emissions – has the potential to decarbonize current hydrogen production and new uses of hydrogen in, for example, steel production. Production of green hydrogen has the following advantages:


Reduction of carbon dioxide emissions in hard-to-abate sectors.


Elimination of the side products of methane use: venting and flaring, water contamination, and long-distance transport.


Ability to produce hydrogen in any location with treatable water and renewable energy.

By reducing the amount of renewable energy employed to split water and increasing electrolyzers’ robustness and durability, 1s1 Energy seeks to reduce barriers to adopting green hydrogen.
