Techno-economic and thermodynamic analysis of pre-cooling systems at gaseous hydrogen refueling stations

Hydrogen refuelling station with integrated metal hydride compressor: Layout features and experience of three-year operation

“…3). 2 The issue has been resolved by the installation of fine inline filters (F1, F2 in Fig. 3) in addition to 0.5 mm grade filters attached to the MH containers; Malfunctions of the control system due to: (i) failures of electric components and (ii) errors of pressure sensors (1.4, 1.5 in Fig.…”

“…Of the total investments in a less expensive H 2 refuelling station (150 kg H 2 /day, truck-delivered H 2 ; USD~600 000, Shanghai, 2007), about 60% relates to the infrastructure providing hydrogen storage, compression and purification [4]. Additional capital costs (10e11%) are necessary to provide hydrogen pre-cooling [1,2,5].…”

On-Board Cold Thermal Energy Storage System for Hydrogen Fueling Process

“…Installation of a pre-cooling system in a hydrogen refueling station invites cooling demand, thus significantly increasing the initial cost, as well as the running costs of the station, in terms of energy consumption [10]. Elgowainy et al [11] conducted a techno-economic and thermodynamic analysis of hydrogen precooling units for T40 stations, and they examined the key factors that contribute to the cost and energy use of hydrogen precooling. Cebolla et al [12] executed filling experiments with different inlet gas temperatures and mass flow rates and stated that the lowest precooling temperature (−40 • C) is not always required in order to meet the user's requirements.…”

Investigation of compressed hydrogen refueling process of 60 L type IV tank used in fuel cell vehicles

“…There are several previous studies on estimation of end temperature and pressure using computational methods . Some of the studies have reported the influence of initial temperature/pressure, precooling strategies, filling time, nozzle geometry, turbulence on end temperature, pressure, and density . A few studies reported the role of heat transfer in refueling, which includes the thermal analysis of the filling process, heat loss modeling, thermal, and mechanical behavior of storage tanks .…”

“…[21][22][23][24][25][26] Some of the studies have reported the influence of initial temperature/pressure, precooling strategies, filling time, nozzle geometry, turbulence on end temperature, pressure, and density. [27][28][29][30][31] A few studies reported the role of heat transfer in refueling, which includes the thermal analysis of the filling process, heat loss modeling, thermal, and mechanical behavior of storage tanks. [32][33][34] In all of these studies, researchers have used the different volume of tanks such as 40, 70, 74, 23, 150 L of type III and 29, 37, and 19 L of type IV tank for experimental and simulation work at maximum pressure of 35 and 70 MPa.…”
