In order to reduce production processes impact and energy consumption keeping the target to increase sustainability, the fundamental strategic need of global industrial policies is moving towards an increasing use of clean and renewable gas, so as to reduce the preponderant dependence on fossil fuels, highly polluting and expensive.
With this in mind, biomethane becomes the Green gas of choice. Produced thanks to the fermentation of agri-food and industrial waste, purification sludge and the organic part of solid urban waste. The decomposition of these organic wastes allows the transformation of the gases produced into biomethane.
ErreDue is part of this virtuous process, thanks to the hydrogen produced with renewable energies through the Mercury and Sirio generators, increasing the quantitative and qualitative efficiency of the biomethane produced.
The biomethanation process, in fact, also produces carbon dioxide. CO2 is not released into the atmosphere, but used in association with the hydrogen supplied by the ErreDue generators, in order to produce more biomethane, thus raising the overall efficiency of the entire process by 80%.
Hydrogen production, which is necessary for biomethanation, requires a lot of energy. Thanks to the technology developed by ErreDue, hydrogen is produced using the surplus of RES, i.e. the excess renewable energy shares, which would otherwise be discarded.
The Mercury and Sirio hydrogen generators therefore allow to:
- obtain cleaner and more efficient biogas, which can be used or sold
- use and exploit the surplus of renewable energy that would have been discarded
- use CO2 that would otherwise be released into the atmosphere
ErreDue has already implemented functional systems for this purpose. An example is represented by the ACEA Power-to-gas system in Turin, which uses a Mercury ErreDue generator, which supplies 85 m3 of hydrogen at 12 bar.
Biomethane use as Green gas through these technologies represents 3% of the current national production of natural gas that is fed into the network for various uses.
In Italy, as in Germany and Denmark, Biomethanation is becoming an increasingly consolidated reality. This is also thanks to the “+ Gas” project that ENEA is developing in which ErreDue is playing a significant role with its own plants: hydrogen, obtained from the electricity surplus of RES, added to CO2 is used to produce high quality Biomethane, derived from organic waste fermentation. Mercury by ErreDue guarantees an 80% increase in the biomethane obtained, through a highly sustainable process. So you get double sustainability with ErreDue Systems.
