1. A method for producing renewable diesel, comprising:

  • (a) heterotrophically culturing a population of microalgae, of the species Chlorella protothecoides, genetically engineered to express sucrose invertase in the presence of sucrose;

    (b) isolating glycerolipid components from the cultured microalgae; and

    (c) subjecting the isolated glycerolipid components to chemical reactions to generate alkanes, wherein the chemical reactions include (hydro)deoxygenation, and isomerization and distillation to remove naptha,whereby renewable diesel is produced.
