A review of analogue case studies relevant to large-scale underground hydrogen storage

Energy Reports, Journal Year: 2024, Volume and Issue: 11, P. 2374 - 2400

Published: Feb. 9, 2024

Underground Hydrogen Storage (UHS) has gathered interest over the past decade as an efficient means of storing energy. Although a significant number research and demonstration projects have sought to understand associated technical challenges, it is yet be achieved on commercial scales. We highlight case studies from town gas blended hydrogen storage focusing leakage pathways reactivity. Experience helium serves analogue for containment security two gases share physiochemical similarities, including small molecular size high diffusivity. Natural are also investigated, well integrity safety challenges. Technical parameters identified having adverse effects security, efficiency, reactivity were then used develop high-level site-specific screening criteria. Thirty-two depleted offshore hydrocarbon reservoirs in UK Continental Shelf (UKCS) potential formations based application our The screened fields reflect large energy capacities, low cushion requirements, proximity wind farms, thereby highlighting widespread geographic availability UHS UKCS. Following initial screening, we propose that analysis existing concentrations investigation local tectonic settings key criteria identifying stored hydrogen.

Hydrogen Valley in Cyprus: Insights and Strategies for Citizen Engagement

Sustainability, Journal Year: 2025, Volume and Issue: 17(2), P. 804 - 804

Published: Jan. 20, 2025

In remote areas or islands like Cyprus, the isolated energy system, high consumption in transport sector and projected excess electricity production from solar sources create favourable conditions for establishing a hydrogen valley. But even after addressing technological, managerial, economic financial challenges, success of valley hinges on acceptance engagement local population. The role citizens is under-researched by academia overlooked policymakers. Our paper’s contribution unique data purposefully developed survey Cypriot residents. findings reveal robust support renewable transition principle, with 90% expressing supportive views, which 57% ‘strongly support’ transition, notably, middle-aged, more educated fully employed individuals showing strongest support. At same time, our results show that 62% are unfamiliar concept economy. promising finding 80% ‘very likely’ (25%) ‘somewhat (55%) to engage discussions activities related creation Cyprus. Gender differences willingness are, however, evident: 32% males indicated they participate versus 23% females. We conclude prevailing citizen behaviour Cyprus “Seeking Information”, we make policy suggestions outlining top ten tools foster awareness among general population strategies targeting active supporters elevate their involvement ‘Action’ ‘Advocacy’ levels engagement.

Towards a unified theory of domestic hydrogen acceptance: An integrative, comparative review

International Journal of Hydrogen Energy, Journal Year: 2023, Volume and Issue: 56, P. 498 - 524

Published: Dec. 28, 2023

Hydrogen energy technologies are envisioned to play a critical supporting role in global decarbonisation. While low-carbon hydrogen is primarily targeted for reducing industrial emissions, alongside decarbonising parts of the transport sector, environmental benefits could also be achieved residential context. Presently, gas-dependent countries such as Japan and United Kingdom assessing feasibility deploying home appliances, part their national strategies. However, prospects transition will hinge on consumer acceptance, an array other socio-technical factors. To support potential ambitions large-scale sustained technology diffusion, this study advances Unified Theory Domestic Acceptance. Through integrative, comparative literature review targeting domestic studies, paper proposes novel Acceptance Model (DHAM), which accounts cognitive emotional dimensions human perceptions. dual interplay, proposed framework can increase predictive power acceptance models.

Abstract Background There is a race to innovate, develop or create hydrogen production technologies accelerate energy transition and economy. Acceptance has been used in social science literature as lens through which anticipate possible challenges surrounding technologies. However, very few studies problematize perceptions focus on the of hydrogen. Hence, this study aims bridge these theoretical empirical gaps using mixed-method approach based semi-structured interviews ( n = 7) questionnaire survey 73) understand stakeholders’ sources construction technology lens.
