“…The proposed configurations were presented by the authors in previous papers [10,[21][22][23], in which the HRSs were sized for smaller hydrogen capacities (100 and 200 kg/day). In [10,21] in particular, ammonia-based HRSs with hydrogen capacities of 100 kg/day and 200 kg/day were proposed, respectively.…”

“…A biogas-based HRS, characterized by an autothermal reforming (ATR) unit, as the hydrogen production system, and sized for a capacity of 100 kg/day, was studied in [22].

“…The purge gas (20) and the cathodic off-gases (23) are mixed and sent to the CB, while the pure hydrogen ( 19) is delivered to the compression section. The exhausts from the CB are used to heat several streams in the plant (heat exchangers HE2, HE3, HE4, HE5, HE7) before being vented (34).…”

In this study, the authors present a techno-economic assessment of on-site hydrogen refuelling stations (450 kg/day of H2) based on different hydrogen sources and production technologies. Green ammonia, biogas, and water have been considered as hydrogen sources while cracking, autothermal reforming, and electrolysis have been selected as the hydrogen production technologies. The electric energy requirements of the hydrogen refuelling stations (HRSs) are internally satisfied using the fuel cell technology as power units for ammonia and biogas-based configurations and the PV grid-connected power plant for the water-based one. The hydrogen purification, where necessary, is performed by means of a Palladium-based membrane unit. Finally, the same hydrogen compression, storage, and distribution section are considered for all configurations. The sizing and the energy analysis of the proposed configurations have been carried out by simulation models adequately developed. Moreover, the economic feasibility has been performed by applying the life cycle cost analysis. The ammonia-based configurations are the best solutions in terms of hydrogen production energy efficiency (>71%, LHV) as well as from the economic point of view, showing a levelized cost of hydrogen (LCOH) in the range of 6.28 EUR/kg to 6.89 EUR/kg, a profitability index greater than 3.5, and a Discounted Pay Back Time less than five years.

“…The O&M cost of each component has been evaluated on yearly basis as a proper percentage of its initial investment cost. The percentages assumed for each plant component have been widely discussed by the authors in a previous paper [11]. For evaluating the cost due to the water consumption (computed as operating costs), the tariffs defined by the Italian Company ABC (sited in Naples) have been assumed [12] Based on these data, this cost consists of a fixed annual cost (€/year) and a cost variable according to water consumption (€/m 3 ).…”

Today, the hydrogen is considered an essential element in speeding up the energy transition and generate important environmental benefits. Not all hydrogen is the same, though. The “green hydrogen”, which is produced using renewable energy and electrolysis to split water, is really and completely sustainable for stationary and mobile applications. This paper is focused on the techno-economic analysis of an on-site hydrogen refueling station (HRS) in which the green hydrogen production is assured by a PV plant that supplies electricity to an alkaline electrolyzer. The hydrogen is stored in low pressure tanks (200 bar) and then is compressed at 900 bar for refueling FCHVs by using the innovative technology of the ionic compressor. From technical point of view, the components of the HRS have been sized for assuring a maximum capacity of 450 kg/day. In particular, the PV plant (installed in the south of Italy) has a size of 8MWp and supplies an alkaline electrolyzer of 2.1 MW. A Li-ion battery system (size 3.5 MWh) is used to store the electricity surplus and the grid-connection of the PV plant allows to export the electricity excess that cannot be stored in the battery system. The economic analysis has been performed by estimating the levelized cost of hydrogen (LCOH) that is an important economic indicator based on the evaluation of investment, operational & maintenance and replacement costs. Results highlighted that the proposed on-site configuration in which the green hydrogen production is assured, is characterized by a LCOH of 10.71 €/kg.

“…Battery Electric Vehicles (BEVs) represent a sustainable solution for the mobility, even if the long recharge time and the high cost of the battery pack are critical issues for their diffusion [2]. The Fuel Cell Electric Vehicle (FCEV), on the other hand, is emerging as a promising solution given its potential to provide both longer range and shorter refueling time; however, the refueling infrastructure is still under development and has high investment costs [3][4][5]. In this context, Plug-in Fuel Cell Electric Vehicles (PFCEVs) overcome the drawbacks of the abovementioned solutions in terms of recharging time, refueling infrastructure and driving range.…”

Development of a plug-in fuel cell electric scooter with thermally integrated storage system based on hydrogen in metal hydrides and battery pack

The thermal management of lithium-ion batteries in hybrid electric vehicles is a key issue, since operating temperatures can greatly affect their performance and life. A hybrid energy storage system, composed by the integration of a battery pack with a metal hydride-based hydrogen storage system, might be a promising solution, since it allows to efficiently exploit the endothermic desorption process of hydrogen in metal hydrides to perform the thermal management of the battery pack. In this work, starting from a battery electric scooter, a new fuel cell/battery hybrid powertrain is designed, based on the simulation results of a vehicle dynamic model that evaluates power and energy requirements on a standard driving cycle. Thus, the design of an original hybrid energy storage system for a plug-in fuel cell electric scooter is proposed, and its prototype development is presented. To this aim, the battery pack thermal power profile is retrieved from vehicle simulation, and the integrated metal hydride tank is sized in such a way to ensure a suitable thermal management. The conceived storage solution replaces the conventional battery pack of the vehicle. This leads to a significant enhancement of the on-board gravimetric and volumetric energy densities, with clear advantages on the achievable driving range. The working principle of the novel storage system and its integration within the powertrain of the vehicle are also discussed.
