Förnybara drivmedel och deras förutsättningar för implementering i Försvarsmakten

Sammanfattning: Today’s society is adapting to reduce the climate footprint which is why the Swedish Armed Forces is expected to revise its use of fossil fuel. The choice of fuel is not obvious, and this report aims to examine the possibilities and limitations for a few renewable fuel’simplementation in the Swedish Armed Forces. Based on Moche Kress logistics concept an analyzing tool were created. The analyzing tool is based on the category’s economy, industry/engine technology, technology/characteristics, inventory, storage facilities and transports. Methods used is a mixture of document collection and interviews with an expert in the area of alternative fuels and combustion engines. The renewable fuels analyzed are FAME, HVO, biogas and DME. Results of the analysis show that FAME has a relative low cost for production, only requires small-scale modifications in engines, the domestic production is expected to expand and is interoperable with the current supply chain. The biggest limitations are the bad qualities regarding cold temperatures and can’t be stored longer periods of time. HVO has a bit higher production cost but has good qualities even in colder temperatures, high energy density, can beused in all diesel engines after an approval from the manufacturer and can be implemented incurrent infrastructure as well as supply chain. Raw materials consist on the other hand largely from palm oil production. Biogas has a relatively high production cost, low energy density, requires extensive renovations/installations of engines/fuel systems and can neither be implemented in current infrastructure nor supply chain. Positive features are its good qualities in cold temperatures and big part domestic production. DME also has good qualities in cold temperatures but requires a new injection system and a new tank, can’t be implemented in neither current infrastructure nor supply chain and is not produced anywhere globally today. Based on the results from the analysis HVO were concluded as the most realistic alternative for the Swedish Armed Forces. Further conclusions were that FAME is not the best alternative and neither biogas nor DME were estimated as a realistic choice today. The last conclusion of the analysis is that none of the alternatives had possible self-sufficiency in Sweden as of now.
