Resumen
In the road to sustainability, the treatment of post-combustion emissions is still far from being
techno-economically viable. On one end, the low concentration of CO2 in these streams, precludes
the use of current carbon capture (CC) technologies. On the other end, even if CC were successfully
implemented, there are not plausible final uses, maybe except geological long-term storage. Our
ambitious proposal aims to investigate the viability of a technology able to tackle these
challenges at once. Our SUPERVAL technology will develop scientific solutions from low-cost,
non-critical raw materials and processes, with the added value of removing/valorizing the NOx
contaminants from flue gas. We propose to design and realize an autonomous, solar-powered
installation able to capture harmful emissions from flue gas, and valorize them as commodities for
the chemical industry, using water as sacrificial source of electrons and protons. The CO2 will be
transformed into an organic, energy-rich molecule (formate). The NOx will be also captured and
transformed, in combination with N2, into ammonia using the hydrogen obtained in the CO2
co-electrolysis processes. This integrated effort will offer the comprehensive capture and
valorization of carbon and nitrogen components in post-combustion emissions, thus limiting
pollutants and resulting in added-value chemicals. The corresponding techno-economic analysis and
life cycle assessment studies will hel ape
the components and performance of SUPERVAL as a useful technological advancement in the search for
zero net emissions.
