Dimethyl Ether (DME), which is used as a propellant in spray cans, can also be used as a fuel. The Swedish government has given permission and funding to Volvo
to develop engines capable of running on the alternative fuel
. Volvo already has developed two generations of DME engines; the project would use third generation engines which would be installed in trucks in 2009 and 2010.
It is unknown if DME engines are part of Sweden's plans
for energy independence by 2020. The fuel could be attractive to the country since it's easily made domestically from paper pulp residue.
