Definition vs examples from EPA
• Alternative fuels, known as non-conventional and advanced fuels, are any materials or substances that can be used as fuels, other than conventional fuels like; fossil fuels (petroleum (oil), coal, and natural gas), as well as nuclear materials such as uranium and thorium, as well as artificial radioisotope fuels that are made in nuclear reactors.
• Some well-known alternative fuels include biodiesel, bioalcohol (methanol, ethanol, butanol), refuse-derived fuel (RDF), chemically stored electricity (batteries and fuel cells), hydrogen, non-fossil methane, non-fossil natural gas, vegetable oil, propane and other biomass sources.

BALTIC SEA FERRY VISION 2020...
Currently 13 ferries are in operation on the
S/N cross-Baltic, Poland – Sweden routes:
- according to TT-Line President, 8 new ships
will be needed within next 10 years, only for
these routes.
