Hydrogen

Hydrogen is the ideal energy carrier for a decarbonized world: 1 kg of hydrogen packs as much energy as 1 gallon (3.8 liter) of gasoline, which can be used either as heat (by burning it) or electricity (using a fuel-cell) with pure water (H2O) as the only waste product.


Hydrogen can be stored for years and can be transported for thousands of miles - just like LNG (Liquified Natural Gas). 

Hydrogen has uses beyond energy: it is already a major industrial feedstock - over 70 million tons of hydrogen were consumed in 2018.

Unfortunately, although hydrogen is one of the most abundant elements on earth, virtually all the hydrogen is “locked up” in molecules, mainly as water and organic compounds.

Hydrogen Production

Today, almost all hydrogen is produced from fossil fuels, in particular natural gas via steam methane reforming (SMR). This is a process that releases large amounts of carbon dioxide. Global hydrogen production is responsible for more greenhouse gas emissions than all of Germany.

Hydrogen can also be produced by splitting water using electrolysis. If non-fossil electricity is used, this process will not cause any direct or indirect carbon dioxide emissions, but it has rather low energy efficiency. This is a disadvantage, since a big chunk of the hydrogen production costs comes from the electricity used.

In contrast, H2Pro’s E-TAC patented process, a variant of water electrolysis, can split water with significantly higher efficiency and at a lower cost.
