Millennium Carbon produces a premium activated carbon that is an ideal adsorbent material for adsorbed natural gas (ANG) and low pressure compressed natural gas (CNG) storage applications.
Today's conventional approaches to natural gas storage are compressed natural gas (CNG) and liquid natural gas (LNG) but both have drawbacks - high costs, low storage efficiency and safety concerns. ANG storage using activated carbon is a favored alternative to these two storage methods. ANG storage provides better storage characteristics than high-pressure CNG storage because it is safer and far more efficient than CNG (500 PSI versus 3500 PSI). Ultra-high surface area activated carbon stores natural gas storage systems at pressures substantially below those typically required for current CNG systems and without the liquefaction and boil-off challenges of LNG.
"Adsorbed natural gas is considered to be a better choice for vehicles than compressed natural gas because the adsorption system has the advantage of low storage pressure."
