Growing concerns about the rapid depletion of fossil fuel reserves,
rising crude oil prices, energy security and global climate change have
led to increased worldwide interest in renewable energy sources such as
biofuels. In this context, biofuel production from renewable sources is
considered to be one of the most sustainable alternatives to fossil
fuels and a viable means of achieving environmental and economic
sustainability.
Although biofuel processes hold great potential to provide a
carbon-neutral route to fuel production, first-generation production
systems are characterized by considerable economic and environmental
limitations. The advent of second-generation biofuels is intended to
produce fuels from lignocellulosic biomass, the woody part of plants
that does not compete with food production. However, converting woody
biomass into fermentable sugars requires costly technologies. Therefore,
third-generation biofuels from microalgae are considered to be a viable
alternative energy resource, free from the major drawbacks associated
with first and second-generation biofuels. This book examines the
background of third-generation biofuel production; the advantages of
algae over traditional biofuel crops; algal biomass production; algae
harvesting and drying methods; production of biofuel from microalgae;
and future prospects.
