2. Hydrogen go-to-market 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.

4. How hydrogen is produced (validated)
• Steam Reforming – Dampfreformierung – Reforma com Vapor
CH4 + H2O  CO + 3H2
• Partial Oxidation - Partielle Oxidation – Oxidaçao Parcial
CnHm + n/2 O2  nCO + m/2 H2
• Autothermical Reform - Autotherme Reformierung – Reforma autotérmica
4CH4 + 2H2O + O2  4CO + 10H2
• Gas Preparation – Gasaufarbeitung – Preparacao do Gas
• Water Electrolyse - Elektrolyse von Wasser – Eletrolise da Agua
H2O + 2e-  H2 + ½ O2
• Biomass – Biomasse – Biomassa
C6H12O6 + O2 + H2O → 6CO + 7H2 +3/2 O2
• Kvaerner Process - Kvaerner-Verfahren – Processo de Kvaerner
CnHm  nC + m/2 H2
• Thermochemical Process - Thermochemische Verfahren – Processo
Termoquimico
• Photochemical Production - Photochemische Herstellung – Producao Fotoquimica
• Photobiologic Production- Photobiologische Herstellung – Producao Fotobiologica
• H2 Production by Alternative Energy sources - Wasserstofferzeugung auf Basis
alternative Energiequellen – Producao de H2 por fontes de energia alternativa

5. ANALYSIS
The World Plastic Pollution Problem
Some key facts:
• Half of all plastics ever manufactured have been made in the last 15 years.
• Production increased exponentially, from 2.3 million tons in 1950 to 448
million tons by 2015. Production is expected to double by 2050.
• Every year, about 8 million tons of plastic waste escapes into the oceans
from coastal nations. That’s the equivalent of setting five garbage bags full
of trash on every foot of coastline around the world.
• Plastics often contain additives making them stronger, more flexible, and
durable. But many of these additives can extend the life of products if they
become litter, with some estimates ranging to at least 400 years to break
down.

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 for plastics

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.
