Descripción del proyecto
Utilizar todo el espectro solar en el hidrógeno verde
Utilizar la energía solar para dividir el agua es una forma limpia de fabricar hidrógeno, pero la eficiencia es baja debido a la limitada captación de luz y a la lenta semireacción de la oxidación del agua. El equipo del proyecto GH2, financiado con fondos europeos, lo resolverá diseñando un sistema que utilice todo el espectro solar en lugar de solo la luz ultravioleta y visible, además de emplear la oxidación de derivados de la biomasa. Los investigadores también mejorarán la eficiencia combinando la fotocatálisis ultravioleta-visible y la catálisis térmica impulsada por infrarrojos, así como un reactor de tubos de doble flujo. El objetivo es producir un rendimiento de hidrógeno del 60 %, así como otros productos químicos de alto valor. También se garantizará que la Unión Europea sea uno de los principales productores de hidrógeno verde.
Objetivo
Water splitting for H2 production driven by solar energy is quite attractive while the current efficiency is very moderate due to both the extremely sluggish water oxidation half reaction and limited light harvesting (mostly UV-visible light). In addition, the separation of one product H2 from the other O2 during water splitting is very costly.
The project is designed to address these challenges by i) utilizing the full solar spectrum (300-2500nm) instead of UV-visible light (300-700nm), ii) coupling water splitting with biomass-derivative oxidation to avoid water oxidation, iii) well combining solid Z-scheme UV-visible photocatalysis and Infrared-driven thermal catalysis, and iv) using a flow double tube reactor other than batch reactors, thus targeting to produce green H2 from both water and biomass with a high quantum yield of 60% . Furthermore the project will co-produce high-value chemicals with a high selectivity of >90%. In addition, the integration of low-cost and efficient catalysts with novel flow reactors will assure a continuous and efficient production of H2 and high-value chemicals. The entire process does not use fossil fuels nor produce CO2, thus a zero carbon-emission technology. Finally the system can be readily scaled up by numbering up the reactor modules. All these are built upon a multidisciplinary and international consortium with the global experts in photocatalysis, thermal catalysis, reactor engineering, product separation, simulation and social science. Therefore the scientific and technical challenges, as well as the environmental, societal and economic impacts will be fully addressed in the project. The proposed technology will typically benefit the EU economy by an innovative green H2 production process from water and biomass, heavily contributing to a low carbon society. In addition, the international team including members from Asia will facilitate the technology exploitation out of the EU, to further benefit the EU economy.
