One of the easiest and most effective ways to reduce oil usage is to make vehicles — no matter what kind of fuel they run on — more efficient. Major auto manufacturers are required to do this to comply with CAFE standards, but the alternative fuel industry is working on it, too, in a race to make newer, cleaner technologies more cost effective and attractive.

Our latest investment is in a Tulsa-based company called Infinite Composites Technologies (ICT), which is working on ways to make vehicles that run on compressed natural gas (CNG) much more efficient by focusing on the fuel tank itself. ICT’s patented design is a lightweight composite tank that holds 10% more fuel than current steel and aluminum CNG tanks, weighs 90% less and has a 10% smaller footprint. Carbon fiber tanks aren’t flashy, but behind-the-scenes tech breakthroughs like this can make a huge difference in things we use every day. - See more at: http://www.sustainableamerica.org/blog/building-a-better-gas-tank/#sthash.i3BFIptT.dpuf
