D5.4 Techno-economic validation: Main conclusions and recommendations

D5.4 Techno-economic validation: Main conclusions and recommendations This report focused on the evaluation of results and compilation of recommendations for a future gas grid. The report proposes four possible gas grids characterized by H2 content and the need for separation. The key findings are as follows: Blending low volumes (0-2 vol.-%) of hydrogen into the […]

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, […]

D2.3 – Hydrogen compatibility in high-pressure grids: technical, RCS barriers, enablers, and innovations

With the focus on infrastructure, european legal, and technical framework, european sector initiatives, certification and national frameworks the final review on barriers, enablers, and innovations of hydrogen compitability in high-pressure grids is now elaborated. The high-pressure transmission gas grid is substantially hydrogen-ready. Some parts of the gas grid still need additional monitoring and approval through […]
