NanoSUN begins R&D project on H2 cooling technology

NanoSUN revealed the launch of its R&D project to design and develop a cost effective process for rapid refueling of hydrogen road freight vehicles.While fuel cell electric vehicles (FCEVs) are available in all sizes, the large scale of road freight makes hydrogen, as a lightweight and rapidly rechargeable fuel, an ideal alternative to fossil fuel based vehicles. However, hydrogen is very dense in energy per unit mass and it must be compressed to high pressures (typically 350 or 700 atmospheres) for storage in on-board pressure vessels to reduce its volume sufficiently for practical use in vehicles. This creates a challenge for developers and manufacturers of hydrogen refueling stations due to the rapid compression of hydrogen into vehicle tanks causing a rise in the temperature of the gas.The conventional solutions to this problem are either to fill vehicle tanks very slowly, allowing the compression heat to dissipate through the tank walls; or to use a mechanical refrigeration system to cool the hydrogen in the refueler storage to below ambient temperatures. However, both options are highly undesirable. The first option negates the advantage of using hydrogen to rapidly refuel. The second is expensive and lowers station reliability because, due to their moving parts, chillers can break-down.In the aim to present a cost effective and appropriate solution, NanoSUN’s scientific experts are now working closely with to validate its technology, to enable rapid commercialization in the hydrogen refueling infrastructure. This could be deployed both on NanoSUN's mobile Pioneer Hydrogen Refueling Stations and also conventional, fixed hydrogen refueling stations located across the nation.
