“…The P2G technology is of substantial interest to renewable-dominated HFSs. These HFSs can integrate one or several types of renewables for H 2 production, such as H 2 -PVT [18], wind-H 2battery [19], wind-photovoltaic-H 2 -battery [20], solar-H 2 -fuel cell [21], biomass-H 2 -PVT [22], and were investigated with respect to cooperative operation and control, optimal sizing and planning, techno-economic assessment, exergy efficiency promotion, and energy cogeneration. However, the low H 2 production efficiency as well as the impact of dramatic electrolysis current fluctuations on the life degradation cost of electrolyzers is not well addressed.…”

Under the pressure of climate change, the demands for alternative green hydrogen (H2) production methods have been on the rise to conform to the global trend of transition to a H2 society. This paper proposes a multi-renewable-to-hydrogen production method to enhance the green H2 production efficiency for renewable-dominated hydrogen fueling stations (HFSs). In this method, the aqueous electrolysis of native biomass can be powered by wind and solar generations based on electrochemical effects, and both electrolysis current and temperature are taken into account for facilitating on-site H2 production and reducing the electricity consumption. Moreover, a capsule network (CN)-based H2 demand forecasting model is formulated to estimate the gas load for HFS by extracting the underlying spatial features and temporal dependencies of traffic flows in the transportation network. Furthermore, a hierarchical coordinated control strategy is developed to suppress high fluctuations in electrolysis current caused by volatility of wind and solar outputs based on model predictive control (MPC) framework. Comparative studies validate the superior performance of the proposed methodology over the power-to-gas (P2G) scheme on electrolysis efficiency and economic benefits.

“…In the generation of energy from renewable sources such as solar, wind, and hydro power, there is an inevitable mismatch between the power demand and supply due to the seasonal and spatial characteristics of these resources [3,4]. Thus, the surplus electricity resulting from this mismatch is expected to be used for hydrogen (H 2 ) production [5,6]. The global demand for H 2 has increased continuously by 3-4% annually [7] and H 2 continues to receive attention as a clean alternative energy carrier based on the fact that it only produces water as a byproduct upon conversion to energy compared to conventional fuel such as natural gas, petroleum, and coal [8].…”

As the global trend towards transition to a "hydrogen society" continues to gain momentum, a lot of studies on alternative hydrogen (H 2 ) production methods are on the rise. Among them, methylcyclohexane (MCH) dehydrogenation in a membrane reactor (MR) is reported here as one possible candidate, affording its enhanced H 2 yield and a compact design. In this study, techno-economic analysis and carbon footprint analysis (CFA) of MCH dehydrogenation in an MR are carried out to investigate economic and environmental feasibility providing techno-economic and environmental guidelines for realizing it as mature technology. The economic parameters are determined through process simulation using Aspen Plus®, and the unit H 2 production costs are obtained for a packed-bed reactor (PBR) and an MR in H 2 production capacities of 30, 100, 300, and 700 m 3 h − 1 . The effects of each economic parameter on the unit H 2 production cost are identified through sensitivity analysis (SA) and scenario analysis is performed under various conditions to investigate the effects of technical parameters of the membrane, such as the H 2 production capacity, temperature, and H 2 permeance on the unit H 2 production costs. CFA is also performed to investigate the environmental feasibility of MCH dehydrogenation in an MR by considering CO 2 emissions at each part.
