In this paper the tecno-economic assessment of two novel hydrogen production plants for small refueling stations is analyzed and compared. In the first one renewable ammonia, that is the hydrogen carrier, is cracked in a Solid Oxide Fuel Cell (SOFC) power unit that cogenerates the required hydrogen and the electric power needed for the hydrogen separation and storage. In the second one the hydrogen production is based on the autothermal reforming of the biogas obtained from an anaerobic digester and the electric power consumption for the hydrogen separation and storage is supplied by an SOFC power unit fed with part of the syngas exiting the biogas processing unit. In both the plant configurations the product hydrogen is separated by means of a Pd-Ag membrane separation unit and is compressed up to 820 bars by using an ionic compression system. The economic performance comparison is based on the evaluation of the levelized cost of the hydrogen (LCOH) for a decentralized hydrogen refueling station (HRS).

Abstract
In this paper the tecno-economic assessment of two novel hydrogen production plants for small refueling stations is analyzed and compared. In the first one renewable ammonia, that is the hydrogen carrier, is cracked in a Solid Oxide Fuel Cell (SOFC) power unit that cogenerates the required hydrogen and the electric power needed for the hydrogen separation and storage. In the second one the hydrogen production is based on the autothermal reforming of the biogas obtained from an anaerobic digester and the electric power consumption for the hydrogen separation and storage is supplied by an SOFC power unit fed with part of the syngas exiting the biogas processing unit. In both the plant configurations the product hydrogen is separated by means of a Pd-Ag membrane separation unit and is compressed up to 820 bars by using an ionic compression system. The economic performance comparison is based on the evaluation of the levelized cost of the hydrogen (LCOH) for a decentralized hydrogen refueling station (HRS).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
