The Case for Biojet Fuel from Bioethanol in Brazil: An Optimization-Based Analysis Using Historical Market Data.

Biojet fuel is an attractive option to reduce global greenhouse gas (GHG) emissions from the aviation industry. In this paper, we propose a two-stage stochastic linear program to analyze the optimal operation of an integrated sugarcane mill that produces sustainable aviation fuel (SAF) using historical time-series commodities price data from Brazil. We find currently available alcohol-to-jet (ATJ) technologies require premiums between 0.

Classical-Equivalent Bayesian Portfolio Optimization for Electricity Generation Planning.

There are several electricity generation technologies based on different sources such as wind, biomass, gas, coal, and so on. The consideration of the uncertainties associated with the future costs of such technologies is crucial for planning purposes. In the literature, the allocation of resources in the available technologies has been solved as a mean-variance optimization problem assuming knowledge of the expected values and the covariance matrix of the costs.
