The project, runner-up in the Ingenia Energy Challenge 2020, takes another step forward in its technological journey by publishing its innovative proposal in The International Journal of Hydrogen Energy.
At Enagás Emprende, we celebrate a new milestone for B-Hydrogen, a project awarded runner-up in the 2020 edition of our Ingenia Energy Challenge program, which has published an article in the International Journal of Hydrogen Energy presenting the results of its research to produce green hydrogen from brewer’s spent grain. This work, driven by Celia Navarro Pedrero —Chemical and Environmental Engineer in Enagás’ Equity Participations Division and co-founder of the B-Hydrogen project— and Alba Martínez —former colleague at Enagás Emprende and currently at the Dutch startup Hyet Hydrogen— in collaboration with a team of CIEMAT and the Rey Juan Carlos University researchers, explores the technical feasibility of transforming this abundant by-product of the brewing industry into high-purity renewable hydrogen through a process of gasification and palladium membrane purification. The study demonstrated that, under optimal gasification conditions, it is possible to generate a synthesis gas with up to 45% hydrogen and achieve the purity required by the ISO-14687 standard for use in fuel cells. The pilot-scale analysis also confirmed the stability and high performance of the developed membranes, paving the way for larger-scale trials and advanced configurations of reactors with integrated membranes.
Beyond its technical impact, B-Hydrogen’s proposal aligns with the principles of the circular economy, offering a double contribution: giving new value to an industrial waste and advancing decarbonization through clean technologies. At Enagás Emprende, we are proud to have supported Celia and the rest of the team at the start of this innovative journey. This achievement reinforces our commitment to supporting ideas from intrapreneurs, in collaboration with the scientific-technological ecosystem, that combine innovation, sustainability, and talent, driving solutions that transform industries and accelerate the energy transition.
About B-Hydrogen
B-Hydrogen was born within the framework of the Ingenia Energy Challenge 2020, with the aim of producing renewable hydrogen from agricultural and industrial by-products. The scaled potential of the proposal, together with the support of a scientific entity, could enable the project to become a benchmark technology in the sector..
