The CNG tank
The idea of Gastank Sweden AB is to produce
and sell volume optimized gas tanks and systems for CNG and compressed
biogas for cars.
As well known one problem with CNG is the need for increased tank
volume compared to the volume need for liquid fuels. Normally the
availably space in the car does not fit to the shape of normal CNG
tanks since the CNG tanks have a cylindrical shape with a circular
cross section. In order to increase the volume of the tanks the
design of our CNG tanks is more adapted to the normally availably
space in the car. Typically the tanks are given a more rectangular
shaped cross section. Thus our tanks can store up to 30 % more CNG
then normal CNG tanks in the same availably space.
The tanks are reinforced mainly with high performance glass fiber
instead of using carbon fibers. This substantially lowers the material
cost of the tanks. The increased tank volume which normally results
in a lower number of tanks per car in combination with a highly
automated and cost effective production results in a very competitive
cost per liter installed tank volume. |
