Need To Rethink Nuclear Energy
For a Low-Carbon Low-Oil World
Today we use nuclear energy for base-load electricity
Electricity is 40% of energy production in the U.S.
Base-load electricity is two-thirds of electricity production
Implies nuclear energy could meet 25 to 30% of energy demand
Need solutions to meet the oil and climate challenge!
An energy solution may be required where
Nuclear power meets 50 to 75% of total energy demand
Nuclear energy has new roles beyond base-load electricity

Fossil Fuels Are Used to Match
Electricity Supply with Demand
Fossil fuels are inexpensive to store (coal piles, oil
tanks, etc.)
Only two options today for peak electricity
Fossil fuels (Usually natural gas)
Hydroelectricity (Available in only some locations)
What replaces fossil-fuel peak electricity if fossil
fuel use is limited or expensive?
Systems to convert fossil fuels to heat or electricity have low capital costs

Why Store Heat?
Nuclear reactors produce heat, thus direct
transfer of heat to storage
Avoid conversion loses to different storage media
(batteries, hydrogen, water at elevation)
Heat storage media (rock) is cheap
Economic costs of inefficiencies are small
compared to electricity
Value of heat is one-third that of electricity
Light water reactors are 33% efficient (electricity
divided by heat generated)
22
Heat Storage Must Be Large or Deep
to Avoid Excessive Heat Losses

Inject steam into oil sands to break oil-water-sand mixture
Heat input up to 20% of the energy value of the oil
Shale oil (U.S., Europe, Mideast)
Heat rock to >350°C to thermally crack oil shale
Recover light oil and gases
Carbon residue remains sequestered underground
Need high temperatures to heat rock in a reasonable amount of time
Heat input ~35% of energy value of recovered oil and gases

Conclusions
Nuclear may need to supply 50 to 75% of the world energy needs if we are to meet low-carbon goals and get off oil
Gigawatt-year storage is a requirement for a low-carbon future—most storage options need nuclear
Differences in energy sources creates the potential for synergistic options Nuclear: Large-scale steady-state build-anywhere heat source
Wind and Solar: Mid-scale variable regional electricity sources
Biomass: Limited carbon resource
Electricity and fuels markets will be coupled

ABSTRACT
Alternative Nuclear Energy Futures
Peak Electricity, Liquid Fuels, and Hydrogen
In the next 50 years the world energy system may see the largest change since the
beginning of the industrial revolution as we switch from a fossil to a nuclear-
renewable energy system. The drivers are climate change and oil dependency.
These drivers indicate the need to consider nuclear energy in a broader role
including using nuclear energy for (1) variable daily, weekly, and seasonal
electricity production by coupling base-load nuclear reactors to gigawatt-year
energy storage systems, (2) liquid fuels production in nuclear biomass and nuclear
carbon-dioxide refineries, and (3) hydrogen production to support fuels and
materials production. This would be a transformational change. First, nuclear
energy may become an enabling technology for the large-scale use of renewables.
Second, electricity and liquid fuels production would be a tightly coupled energy
system. Such a future would require successful development of multiple nuclear-
user technologies such as gigawatt-year heat storage, high-temperature
electrolysis for hydrogen production, and hydrocracking of lignin.
