2. AGENDA
Hydrogen is an energy carrier, a chemical commodity and a
intermodal platform for decarbonization

3. Hydrogen is the Number One.
Hydrogen (H) is the lightest and most abundant element in the universe, the
number one on the Periodic Table of the Elements. It is the fuel of the stars, like
the Sun. On the Earth hydrogen is not freely available in any significant amount,
but bond to other elements and must be extract from compounds like water,
metal hydrates, hydrocarbons or carbohydrates. Hydrogen gas (H2) is a
colorless, non toxic gas. Gravimetric it has the highest energy density of all non
radioactive materials.

4. Hydrogen color palette
Brown: The H2 produced by mineral coal gasification;
Grey: The H2 produced by natural gas steam reform (SMR);
Blue: The H2, produced by the above-mentioned methods with carbon capture
and storage (CCS);
Green: The H2 produced by water electrolysis, utilizing wind and solar energy;
White: the H2 produced by gasification of renewable sources, like biomass or
plastics at end-of-life, to syngas, a gas essentially composed of H2 and carbon
monoxide (CO), by simple gas separation.

There are seven roles for hydrogen in the energy transition
Act as a buffer to
increase system
resilience
Distribute energy
across sectors and
regions
Enable large-scale
renewables integration
and power generation

Decarbonize
transportation
Help decarbonize
building heating and
power
Decarbonize industry

6. ANALYSIS
By converting plastics, which are mostly derived from fossil oil, and composed
mainly of hydrogen and carbon, to syngas without emission, we produce H2
saving the same amount of fossil fuel and avoiding CO2 emissions. White
hydrogen is a viable way to transform the problem of non-recyclable plastics into
a green solution.
Hydrogen is the link between decarbonization
and circular economy

Gasification
The LTC plants utilize progressive thermo-catalytic material gasification. The material is gasified by
infra-red induction heat bellow 450°C and integrated gas purification, all within a hermetically
closed system. The result is a clean process with very high yield. The plants fluidized bed reactors
allow for continuous flow while inductive heat transfer decomposes organic structures into their
constituent elements in a multi-stage process.
