D6.1 Review of the potential of H2 injection in European grids

D6.1: Review of the potential of H2 injection in European grids Country-by-country study of the expected demand and potential production, predicting flows of hydrogen based on the existing grid capacity. Forecasts towards 2040 and 2050. The main goal of D6.1 is completing the work already started in WP2 about the state-of-art of the European transport […]
D4.3 Update of the status of the ongoing experimental campaign

D4.3 Update of the status of the ongoing experimental campaign. Impact of blends of hydrogen up to 30 mol% on the transport grid assessedImpact of hydrogen on steels, couplings and elastomersTightness of components towards the blend studied Deliverable D4.3 gathers the results obtained in the different tests performed during the 2nd and 3rd experimental campaigns, […]
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, […]
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 […]
D5.1 – Baseline, assumptions and scope for techno-economic modelling of hydrogen admixture into the gas grid

The report “Baseline and case studies definition” aims to develop the basics which are of fundamental importance for the further tasks in work package 5 of the HIGGS project. The report is divided into three main chapters. The section on baseline includes studies on the present and future consumption of natural gas and hydrogen in […]
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 […]
