Green hydrogen leads to zero pollution

H2 – Planet-friendly power

  • H2 is the most powerful gas, it contains no carbon, it does not pollute, it is lighter than air and it is odourless. It can be used to facilitate electricity production and energy storage. When used, the only bi-product emitted is harmless water vapour.
  • The debate is over and the evidence is in. Climate change is a reality because we are in the process of destroying our home, planet Earth. Our future depends on replacing our current, damaging energy sources with energy that does not harm the climate, land, sea, people or animals.
  • Hydrogen, electricity and other energy vectors, in a large-scale application, allow to fully satisfy all the final uses of energy that the human society needs for its social and economical development.

The many uses of hydrogen (H2)

  • In the fight against climate change, hydrogen made with renewable electricity is increasingly seen as a silver bullet for sectors with particularly high emissions

  • Hydrogen promises to be an extremely versatile tool in the race to decarbonization of many industries. It can be used to store energy for an unlimited time, and as an energy vector, for example in the transport sector. It also can be used to make synthetic fuels that can replace fossil fuels as a feedstock in combination with CO2, for example to make plastics. A further advantage is that it can be traded internationally.
  • Green hydrogen is tomorrow's oil. The flexible energy carrier is indispensable for the energy transition and opens new markets. The energy of sun and wind can thus be stored, transported and used as required with a versatile energy vector.

Hydrogen production methods

  • Hydrogen is the most abundant element on the planet, though rarely available in its free molecular state (H2). Instead, it is usually found in combination with other hemical elements.
  • hydrogen (H2) is not an energy source, it is an energy vector that can store and supply large quantities of energy without creating CO2 emissions during combustion. 
  • Currently, over 99% of the hydrogen used in the chemical industry, transportation, heating, etc. is produced from fossil fuel (gas or coal) or non-renewable energy (electrolysis using electricity from diesel, coal, gas or nuclear).
  • Current H2 production solutions all lead to certain form of contaminations. H2GREEN approach is 100% CIRCULAR and does NOT pollute

Powerful energy vector

Hydrogen is known as a technically viable and benign energy vector for applications ranging from small-scale power supply in off-grid modes to large-scale chemical energy exports. However, with hydrogen being naturally unavailable in its pure form, traditionally reliant industries such as oil refining and fertilisers have sourced hydrogen through emission-intensive gasification and reforming of fossil fuels.

Although the mass deployment of hydrogen as an alternative energy vector has long been discussed, it has not happened yet because of the lack of low-cost hydrogen generation and conversion technologies. The recent tipping point in the cost of some renewable energy technologies such as wind and photovoltaics has mobilised continuing sustained interest in renewable hydrogen through water splitting. Enzymolysis with H2GREEN system will bring and create new prospects to drive the hydrogen economy efficiently. Renewable energies combined with enzymolysis is the answer we need for a green and sustainable economy.

Green hydrogen – a necessity

Different production methods produce different types of hydrogen, some more environmentally-friendly than others. Any hydrogen is better than the alternatives, but green hydrogen is best of all. It’s produced through the electrolysis of water molecules (H20) yp split it into hydrogen and oxygen using electricity that is generated entirely from renewable sources (i.e. wind energy, solar energy, tidal energy, etc.). The resulting H2 can be stored to be used at a later time to produce electricity = and the only by-product is water vapour.

Instead of polluting and climate changing fossil fuels, with the H2GREEN system we get a renewable cycle from water back to water.

Hydrogen storage means no wastage of solar and wind energy

Solar and wind energy cannot be produced on demand, so they are often available when not needed, and vice versa. The electricity can’t be stored beyond the limits of battery capacity. This can lead to shortages, when there’s not enough sun or wind, or to saturation of the grid when ‘too much’ energy is available.

To avoid wastage, the excess electricity produced by wind turbines and solar panels can be used to produce hydrogen. The hydrogen can be stored and used, for example, to power hydrogen fuel cell electric vehicles (FCEV) or to heat buildings.
