Heavy dependence on petroleum and high greenhouse gas (GHG) emissions from
the production, distribution, and consumption of hydrocarbon fuels pose
serious challenges for the United States (US) transportation sector.
Depletion of domestic petroleum sources combined with a volatile global oil
market prompt the need to discover alternative fuel-producing technologies
that utilize domestically abundant sources. The primary aim in the discovery
of hybrid energy processes is to combine coal, biomass, and natural gas to
meet the United States transportation fuel demand.

The first part of this presentation will outline the needs and introduce
novel hybrid feedstock coal, biomass, and natural gas to liquids (CBGTL)
process alternatives. The second part will address important decisions at
the process design and process synthesis level. A thermochemical based
process superstructure, its mixed-integer nonlinear optimization (MINLP)
model, and systematic approaches for its global optimization will be
discussed. The third part will introduce a novel framework for the optimal
energy supply chain of CBGTL processes. The optimal network topology
provides information on (i) the optimal plant locations throughout the
country, (ii) the locations of feedstock sources, (iii) the
interconnectivity between the feedstock source locations, CBGTL plants
locations, and the demand locations, (iv) the modes of transportation used
in each connection, and (v) the flow rate amounts of each feedstock and
product type. Life cycle analysis on the nationwide energy supply chain
shows that at least 50% reduction of GHG emissions is attainable.
