- W14491336 abstract "Ensuring a secure, stable and affordable supply of liquid fuels for the transport sectornhas emerged as a key concern of many governments worldwide. To identify the efficientnportfolios of fuel supply available to a country, the security of available fuel supply optionsnmust be balanced against the cost of those fuels. This study first demonstrates the use ofnmean-variance portfolio theory approaches to identify the optimal transport fuel supply fornthe United States and Japan in the present day. We then construct a transport fuel securitynindex (TFSI) to assess the security of potential fuel sources, such as crude oil and biofuels,nby including indicators for diversity of supply and geopolitical risk. For comparison with thenmean-variance approach, the TFSI is used as a measure of risk for identifying optimal fuelnsupply portfolios in the present day for the USA and Japan. According to both the mean-nvariance and TFSI approaches, we find that the existing fuel mixes of the USA and Japanndo not lie within the efficient set of available fuel supply portfolios. We then apply the TFSInto various scenarios for the year 2030, based on current fossil fuel projections and techno-neconomic evaluations of emerging algal biofuel technologies, to identify a set of efficient fuelnportfolios for 2030. Our results show that advances in biofuel technology have the potentialnto improve both the affordability and accessibility of the fuel supply in 2030, and that thisncontribution is dependent on both the level of algal technological development and the pricenof crude oil in the future.n" @default.
