In response, I can only quote their report because I don't have any further details.
$this->bbcode_second_pass_quote('', 'I')n the transportation sector, the study found a somewhat smaller role for
natural gas. The use of compressed or liquefied natural gas as a fuel for
vehicles could help to displace oil and reduce greenhouse gas emissions,
but to a limited extent because of the high cost of converting vehicles to
use these fuels. By contrast, making methanol, a liquid fuel, out of natural
gas requires much less up-front conversion cost and could have an impact
on oil usage and thus improve energy security, but would not reduce
greenhouse gases.
Remove policy and regulatory barriers to natural gas as a transportation
fuel.
$this->bbcode_second_pass_quote('', 'N')atural-gas consumption will increase dramatically and will largely
displace coal in the power generation sector by 2050 (the time horizon of
the study) under a modeling scenario where, through carbon emissions
pricing, industrialized nations reduce CO2 emissions by 50 percent by
2050, and large emerging economies, e.g. China, India and Brazil reduce
CO2 emissions by 50 percent by 2070. This assumes incremental
reductions in the current price structures of the alternatives, including
renewables, nuclear and carbon capture and sequestration.
