Socio-technical barriers to domestic hydrogen futures: Repurposing pipelines, policies, and public perceptions

Reconfiguring European industry for net-zero: a qualitative review of hydrogen and carbon capture utilization and storage benefits and implementation challenges

“…Third, the emergent literature discusses risks and implementation challenges in depth, including environmental consequences, 44,48 geopolitical risks, 49 commercial risks, 50 contingency plans 51 and uncertainties. 52 We thus ask: what are the most significant barriers and challenges facing hydrogen and CCUS implementation?…”

“…157 Research notes that underlying shortcomings in the design, manufacture and maintenance of hydrogen production and transport and storage require new training skills in the UK workforce. 50 Regardless of the hydrogen production pathway, a surge in proficient technicians would be essential for the widescale implementation of heating homes with hydrogen, using fuel cells for vehicles or decarbonizing industry. 158,159 Walker et al 160 even warned that the transition to household hydrogen appliances could potentially strain the UK's local labour resources.…”

Comprehensive Review of Hydrogen Leakage in Relation to Fuel Cell Vehicles and Hydrogen Refueling Stations: Status, Challenges, and Future Prospects

“…Currently, mitigation of greenhouse gas emissions and transformation of fossil energy to renewable energies are two important and urgent challenges to sustainable development of human community. , Among many renewable alternatives, hydrogen energy is one of the most important ones . Many states around the world have intensified their research and development of FCVs and the popularization of HRSs. − It is expected that by 2035, global FCVs ownership will reach 1 million vehicles, and the number of HRSs will reach more than 5000. , However, hydrogen, when stored in high-pressure form (e.g., 35 MPa/70 MPa) and used in low-pressure form (1 MPa), is susceptible to leakage through microgaps due to its small molecule size, low density, and low viscosity. When hydrogen leakage occurs, it would be more likely to mix with the surrounding air in variable scenarios and becomes flammable and may even lead to a blast if without effective actions to avoid high concentrations of hydrogen.…”

A Comprehensive Systematic Overview of Canadian Hydrogen Supply Chains Downstream

“…Europe as a new customer will radically change the downstream of the Canadian HSCs. Furthermore, Gordon et al (2023b) emphasize the significance of addressing HSC downstream challenges, e.g., pipeline repurposing, for expansion of HSCs. Thus, investigation into Canada's HSC downstream forms the essence of this paper.…”
