"Flue gases, produced in industries and power plants are one of the main responsible of both CO2 and NOx emissions into the atmosphere. Carbon dioxide is considered the main green-house gas (GHG). NOx are hazardous and highly reactive compounds causing major health (cardiovascular and respiratory problems, asthma) and environmental (acid rain, photochemical smog, depletion of stratospheric ozone, promoting formation of secondary aerosol) issues. Moreover, flue gases are mostly composed of nitrogen (around 65-90%) which is just released into the atmosphere and wasted.
The SUPERVAL project is funded by the European Union, under the EIC Pathfinder Challenges 2022 call, with €3.5 million to develop low-cost, non-critical raw materials and processes, with the added value of removing/valorizing the NOx contaminants from flue gas and, in combination with N2, transform them into ammonia. Likewise, the CO2 will be captured and transformed into an organic, energy-rich molecule (formate). Overall, SUPERVAL aims to implement a sustainable valorization cycle using sunlight as primary energy source, and water as source of hydrogen (protons and electrons)."
