Catalysis
for fuel refinement, synthesis and utilization
Currently, catalysis touches many
aspects of our economy and will
continue to play an important role in
the development of our future
energy portfolio.

Materials and Chemistry at Extremes
• Effects of chemical extremes on materials performance and
lifetimes limit efficiency and environmental benefits of
advanced energy schemes (turbines, geothermal, fuel cells,
batteries, advanced steam, heat exchangers and transfer
systems, etc.)
• Extreme chemical reactivity provides possible new
pathways for materials synthesis and discovery
• Reactivity extremes challenge our scientific understanding
of materials behavior
o How do reaction pathways/mechanisms change when
materials are subjected to extremes, including being far
from equilibrium?
o How do bulk and interfacial structures evolve under extreme
reactant conditions?
o What new phenomena emerge under extremes in reactants?
• State-of-the-art theory, modeling, spectroscopies,
microscopy, and scattering techniques needed to further
our mechanistic understanding of materials and interfacial
behavior in extreme environments

Materials in Nuclear Systems
• Nuclear power currently provides a
significant fraction of the United States’ noncarbon emitting power generation.
• Modern materials science plays a pivotal role
in both the extension of the life of the
existing fleet and in the deployment of new
modern light water reactors, advanced
reactors with non-water coolants, small
modular reactors, and fusion energy.
• Materials degradation in a nuclear power
plant is extremely complex due to the various
materials and environmental conditions
• Research involving mechanistic
understanding of degradation, use of
modeling and simulation tools, modern
microscopy, and innovative ideas will be
required to solve these issues and advance
nuclear materials science.

Electrical Energy Storage
• New materials, chemistries,
architectures, and separators for
improving energy and power
densities, charging rate, lifetime
and safety of batteries and
capacitors for transportation and
stationary storage.
• New computational tools for
developing new materials and
chemistries and for predicting
device performance and
lifetimes.
• Development of analytical tools
for studying underpinnings of
redox reactions and charge
transport under both
thermodynamic and kinetic
conditions.

Materials for Energy Efficiency
Materials and chemical processes designed to reduce energy
consumption are an important aspect of realizing a sustainable
energy future.
– Building materials, including “smart” materials that
change with environmental conditions
– Recovery of waste heat via conversion to electricity or
storage for later use
– Improved solid state lighting and electronic displays
– Efficient production of chemicals and materials used in
agriculture, pharmaceuticals, bulk chemicals, consumer
products and other applications.
– Low energy separation process for use in water
purification, carbon capture, or other industrial processes.
– Computational and analytical tools, including sensors

Enhanced Oil Recovery and
Unconventional Oil and Gas
• New methods to improve oil
extraction efficiency from existing
deposits such as chemical flooding,
or combining enhanced oil recovery
with CO2 capture and storage.
• New techniques to economically
extract oil and gas from
unconventional deposits and reduce
the environmental impact of
production.

Unconventional reservoirs are located throughout the continental United
States on both private lands and federal lands that are administered by
BLM, Forest Service, Park Service, and FWS (see fig. 2). 8
