The decarbonisation of our economy system is a must to avoid dramatic consequences for our Society. • The transition must be as fast as reasonably achievable:
avoiding social, economic and environmental problems, & • A fast transition is only possible considering
all the available technologies and resources. • There is no a unique solutions, but a combination of
approaches and tools to achieve the target of CO2emissions reduction and/or elimination.
• Hydrogen is called to play an important role as energy vector, and an important component of natural gas.

RESPONSIBLE RAW MATERIALS CONSUMPTION
It is a matter of concern that in seeking to improve the solar energy efficiency: 1) valuable and rare (rare-earth) materials are used: energy is renewable but materials are not; 2) new materials are produced and consumed, many of which consist of toxic substances: solar panels are a source of 300 times more toxic waste than nuclear power plants (countries like Ghana, India and China, where many live off of e-waste, will suffer from "solar trash" far serious than the countries where solar panels are used)

METHAN PYROLYSIS
METHANE DECOMPOSITION TECHNOLOGY With methane pyrolysis technology we have the power to create a long-term sustainable future Europe – even under conditions of full decarbonization. Methane decomposition has the following properties: • Methane decomposition splits off carbon in solid state from methane
(i.e. before the latter is burnt). The results of this process are 100% CO2-neutral hydrogen from natural gas and carbon black (a valuable raw material). The hydrogen can be used in almost all current application areas of natural gas. The carbon black has many industrial uses (it is very pure) or can be deposed.
• The key advantage of this technology is that it requires no CO2-capturing and
storing since the carbon emerges from the process in a solid state.
IEA WEO 2018: “Another option would be to split natural gas into Hydrogen and a solid carbon residue called 'carbon black’ through a process called ‘methane Splitting’. Carbon black can be used in tires, ink, paints and electrical equipment and, if sold, could help lower the overall costs of low-carbon Hydrogen production. “
