By using waste materials as feedstock SYNTHEC FUELS hydrogen is far more economic than Green Hydrogen and it is more sustainable than Gray or Blue Hydrogen.

Green Hydrogen is produced by electrolysis of water, using only electricity from renewable energy sources (Wind and solar energy) for the electrolysis. Regardless of the electrolysis technology chosen, hydrogen is produced CO₂-free, as the electricity used is 100% from renewable sources and is therefore CO₂-free.

Grey Hydrogen is obtained from fossil fuels. During production, natural gas is usually converted into hydrogen and CO₂ under heat (steam reforming).
The CO₂ is then released unused into the atmosphere, thereby intensifying the global greenhouse effect: the production of one tonne of grey hydrogen produces around 10 tonnes of CO₂.

Blue Hydrogen is grey hydrogen, but its CO₂ is captured and stored during its production (carbon capture and storage, CCS). The CO₂ produced during hydrogen production does not escape into the atmosphere and hydrogen production can be considered CO₂-neutral in the balance sheet.

Turquoise hydrogen is produced by the thermal cracking of methane (methane pyrolysis).
Instead of CO₂, solid carbon is produced.

Hydrogen (H₂) in Comaparison to Batteries: 23 x lower Price

Hydrogen (H₂) in Comparison to Batteries: 25 x higher Energy Density

In terms of mass, hydrogen has the highest energy content of all fuels.

One kilogram of hydrogen contains about as much energy as three liters of Gasoline or Diesel.
Another advantage of hydrogen is that its “combustion”, i.e. the reaction with oxygen in a Fuel Cell, produces only water. This leads to lower CO₂ emissions and no fossil fuels are consumed.

• The energy content of the produced sustainable hydrogen comes from waste which already exists in abundance worldwide and not from surplus high-quality renewable electricity
• Plant availability: 7.500 full load hours per year including two maintenance revisions
• It is far more economic than Green Hydrogen and more sustainable than Gray and Blue Hydrogen
• With hydrogen from waste we can reduce our import demand for oil and gas
• Avoidance of over-fertilisation and contamination of groundwater by recycling liquid manure, sludge such as fermentation residues, manure or sewage sludge in accordance with the EU – Nitrate and Water Framework Directive
• Reduction of waste – landfills including their ongoing maintenance, monitoring, decommissioning and decades of aftercare
• Unnecessary incineration of waste that could be recycled and avoided
• Sensible and valuable reuse of plastic waste
• Connection of the energy sector – waste management – mobility – district development
• By producing hydrogen with the innovative SYNTHEC FUELS technology we optimally fulfill the demands in the German “Kreislaufwirtschaftsgesetz – KrWG” (waste management law)
• Consumption of only 0,2 litres Water per 1 kg sustainable hydrogen produced, compared to a consumption of 9,0 litres drinking water per 1 kg Hydrogen if produced via electrlyzer
  9 kg of water for a 1 kg of hydrogen, that is the stoichiometric value. Technically, due to the water treatment usually required, a higher, often even a significantly higher quantity of raw water is needed, especially if seawater is desalinated for this purpose. Taking the average value of the approximately 16,000 desalination plants in operation in 177 countries worldwide, 1 l of fresh water is produced from 2.5 l of raw water (data from: The state of desalination and brine production: A global outlook). If water from these plants were used for hydrogen production by water electrolysis, the technical water requirement would be almost 22.5 kg of raw water per 1 kg of hydrogen.
