DUAL HYDROGEN DISPENSING STATION AT 350 BAR AND 700 BAR FOR THE CSIC

ARPA wins the state tender called by the CSIC (Spanish National Research Council) for the development and manufacture of the first dual hydrogen dispensing station in Spain, with two pressure levels, 350 bar for heavy vehicles and 700 bar for light vehicles.

As a research and demonstration project in collaboration with the CSIC, the intention is to offer a real public dispensing service in a reliable and monitored way. The behaviour of the equipment involved in the station and the fundamental parameters of the vehicle being recharged at any given time will be analysed in depth, including the pressure and temperature of the vehicle's internal tanks. The objective is to optimise the balance of the plant as much as possible with different levels of pressure and cascade dispensing.

In recent years, technological barriers in the treatment of hydrogen have been overcome, such as the increase in the performance of electrolysers, the development of more robust fuel cells for vehicles and more energy-efficient hydrogen compressors.

Currently, it is necessary to implement reliable and monitored high-pressure dispensing stations @700 bar, which will not exist in Spain until 2023, and which are connected to the European HRS network.

This project has been identified as being of national interest and is funded by the European Union's NextGeneration funds.
