D5.3 – Intermediate report: key findings on potential and enablers

D 5.3 – Intermediate report: key findings on potential and enablers D5.3 reveals that large scale hydrogen separation costs can be decreased to 13,812 €/m2, which is 37% lower than lab scale separation. The report also shows that the cost of separating 1 Nm3/h of hydrogen is expected to be around 0.95 €/Nm3 of H2, […]

D4.2 Report on results of the validation

D4.2 Report on results of the validation Deliverable D4.2 gathers the results obtained in the different tests performed during the first and second experimental campaigns, carried out in the R&D testing platform built in WP3 at Fundación Hidrógeno Aragón (FHA). This R&D facility aims to reproduce a natural gas transport grid at smaller scale, where […]
