EnerG2 has leveraged its polymer chemistry technologies to develop materials for adsorbed natural gas (ANG) applications

Today's conventional approaches to natural gas storage are compressed natural gas (CNG) and liquid natural gas (LNG), but both have significant drawbacks - high costs, low storage efficiency and public safety concerns. The favored alternative to these two storage methods is adsorbed natural gas (ANG) on a porous medium such as activated carbon. EnerG2 has leveraged its synthetic carbon nanotechnology to develop materials for ANG applications. ANG provides better storage characteristics than CNG storage because it is safer and far more efficient than CNG (500 PSI versus 3500 PSI). Over 20 percent of the cost of CNG is related to compression; high-performance ANG can significantly reduce this expense. EnerG2 has developed ultra-high surface area carbon materials that can be applied in 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 technology holds the promise of revolutionizing transportation fuels. The global vehicle fleet is over 95% dependant today on petroleum. ANG would allow transportation fuel to transition to clean, abundant and low cost natural gas, dramatically lowering pollution while easing the economic burden of dependence on petroleum-based transportation systems.
