NET ZERO AND THE ENERGY OF THE FUTURE
Achieving the Net Zero target for most countries and companies by 2050 requires major shifts in current generation from fossil fuels to green energy solutions.
Its transition involves greater use of Liquefied Natural Gas in a first instance of transition, it provides a more efficient and easier to produce solutions with zero emission of pollutants.
The most cost-effective green energy sources are renewable. Its production requires sun and wind, which in turn are seasonal and not storable.
Hence, overcoming the challenge of using green hydrogen as a viable fuel from renewable energies is seen as an important part of a carbon neutral future. Obtaining and transforming it into “clean” fuel requires a large amount of renewable energy.
It is also a difficult gas to store and transport over long distances. However, liquefied or transformed into ammonia or methanol could be the best clean energy solution for all countries in the world that today use coal or petroleum derivatives to generate their energy needs.
WHY GREEN H2?
Hydrogen as a fuel can be of different “colors”. These classify it according to the energy source used to produce the hydrogen fuel. There is gray hydrogen, produced from fossil fuels. When this production comes from natural gas and when there is carbon capture and storage, we have blue hydrogen.
Green hydrogen is the one produced from electrolysis, preferably. However, it requires initial green energy to carry out this process, which will come from renewable sources so that the fuel fits into the Net Zero category. Thus, its production takes place without the emission of carbon. That's why experts see this type of fuel as key to a carbon neutral world.
Green hydrogen and its derivatives will be a valuable commodity for Brazil, which has plenty of sun and wind to produce renewable energy. The country is seen as an important potential producer and exporter of the product and has been attracting investments from countries interested in the technical and economic viability of this energy source to replace their fossil energy-based matrices.
