Cost Optimization of US Sustainable Aviation Fuel Supply Chain Under Different Policy Constraints
… emissions of a potential sustainable aviation fuel supply chain in the US in 2035 while incorporating regional uncertainty analysis. Feedstock availability is quantified using projected arable land availability, agricultural yields, and projected waste and residue availability. A mixed-integer …

Optimization of a Hydrogen Alternative Aviation Fuel Supply Chain Under Demand and Emissions Constraints - A Case Study of Canada
… of using hydrogen-based alternative aviation fuels, to meet national greenhouse gas (GHG) emissions reduction commitments was investigated using a mixed-integer-linear-program (MILP) optimization model that minimized the total energy consumed “energy intensity” for a hydrogen-based alternative …

Multiple Asteroid Retrieval Mission
… of the spacecraft fleet is set at 30 years. A fuel supply-chain is proposed and designed so that each spacecraft is refueled before departing for each asteroid. To maximize access to the number of asteroids and retrievable mass for each mission, we propose launching each mission from an orbit …
