Quantification on fuel cell degradation and techno-economic analysis of a hydrogen-based grid-interactive residential energy sharing network with fuel-cell-powered vehicles

Hydrogen-based (H2-based) interactive energy networks for buildings and transportations provide novel solutions carbon-neutrality transition, regional flexibility independence on fossil fuel consumption, where vehicle cells are key components H2-electricity conversion clean power supply. However, due to the complexity in thermodynamic working environments frequent on/off operations, proton exchange membrane (PEMFCs) suffer from performance degradation, depending cabin heat balance requirements, ignorance of degradation may lead overestimation. In order quantify cell both daily cruise vehicle-to-grid (V2G) interactions, this study firstly proposes a two-space thermal model ambient temperature PEMFCs supply HVAC systems. Afterwards, stack voltage is proposed multiple purposes, such as transportation V2G interactions. two models coupled community-level based building-vehicle network, consisting twenty single residential buildings, rooftop PV systems, four hydrogen vehicles (HVs), H2 station, community-served micro grid, local main pipelines, located California, U.S.A. Comparative analysis with without conducted impact dynamic operating cost. Furthermore, parametrical integrated HV quantity grid feed-in tariff reach trade-off strategies between associated costs import cost savings. The results indicate that, hydrogen-based total 3.16% per within one year, 2.50% 0.66% caused by respectively. H2-based community, US$6945.2, accounting 33.4% at $20770.61. sensitivity showed when increases twenty, each decreases 2.50%, whereas 42.8% Last but not least, saving interactions can compensate reduced 40%. Research basic modelling tools respect supply, together techno-economic feasibility analysis, paving path development transition.
