Energy efficient automobile cooler for the supercritical storage of natural gas
In this project an energy efficient small-sized cooler for automotive application was developed. The main objective is the cooling of cold stored, pressurized natural gas at temperatures down to -80 °C (-112 °F / 193 K) and 200 bar (2900 psi) — also known as cryocompressed. At this temperature the density of natural gas is about two times higher compared to being stored at room temperature and under the same pressure, see figure 1. This results in a doubled driving range for motor vehicles.
This active cooling unit has to keep a low temperature in the pressure vessel while the vehicle is not in use so to prevent heating of the cold stored gas and boil-off. The complete system is compact, low-weight, robust and low-cost unit with high reliability.
