Natural gas is much better suited for pickups and other large vehicles than electrification.

Regulators Defend Fuel Standards” (U.S. News, July 19) notes the growing tension between consumer desires for larger, less fuel-efficient light trucks and ambitious automotive emissions and efficiency targets set by the Environmental Protection Agency. There is a proven but unfortunately overlooked solution to this problem: fueling light trucks with natural gas. Natural gas is much better suited for pickups and other large vehicles than electrification and conventional natural gas can reduce greenhouse-gas emissions by 20%. Even better, greenhouse-gas emissions can be reduced by 90% or more with renewable natural gas captured from landfills or dairy farms, which is already providing over half of natural gas-vehicle fueling in California today.

These emissions benefits are easily on par with electric vehicles but regulators and legislators alike have failed to provide the same level of support. In particular, natural-gas vehicles ought to be eligible for the $7,500 federal tax credit that is currently available only to electric vehicles, as well as the considerable regulatory incentives for EVs provided by the EPA and California Air Resources Board. European countries such as Germany and Italy have proved that natural gas can become a low-cost, widely used alternative fuel with the right policies. With similar government support in the U.S., natural gas could allow auto makers to provide low-emission alternatives for the larger vehicles that consumers are gravitating toward.

why ty ty kind sir for sharing those resources!

The storage issue is a pressure/volume problem.  Basically, If you double the pressure, you double the amount of gas that can be stored in a given volume, but you have to build everything on the fueling and tankage side to handle that pressure.  IMHO, current fueling infrastructure is already at about max pressure for consumer CNG.   

For long haul trucking, heavy duty fleet use, and other heavy duty applications, LNG which is stored as a liquid at lower temperatures is a better choice.  But there are fewer public fueling options, and higher upfront costs on the tankage system.
