President of Shell, Panelists See Energy Security in Alternatives
September 21, 2006
AUSTIN, Texas—John Hofmeister, president of Shell Oil Company,
told an audience at The University of Texas at Austin that the time
for debate over the science of climate change is past.
Citing a “linkage” between greenhouse gases and climate change,
Hofmeister called for a national strategy to reduce carbon dioxide
emissions. “The nation needs a public policy,” he said. “We'll
adjust.”
Though he supports a national policy, Hofmeister believes a newly
passed California law requiring the state to reduce greenhouse
emissions by 25 percent by 2020 goes too far.
Hofmeister spoke during an international energy security symposium
co-hosted Sept. 20 by the university’s Jackson School of Geosciences
and the Lyndon B. Johnson School of Public Affairs.
He cited weaknesses in the U.S. oil supply chain as a threat to
energy security.
“We are as vulnerable today as we were a year ago,” said
Hofmeister, referring to supply disruptions from Hurricanes Katrina
and Rita, which knocked out 30 percent of crude oil and gas
production in the Gulf of Mexico, causing a spike in energy costs.
The problem, he said, is that oil is produced just barely fast
enough to meet global demand. “Each day, the world produces about 85
million barrels of oil and consumes about 84 million barrels,” he
said. “That doesn’t leave much extra for unexpected problems or
disasters.”
Hofmeister said that no new public policies have been enacted to
address U.S. energy security since Katrina. He offered five
solutions:
- Open more federal lands to oil and gas drilling, such as parts
of the U.S. Outer Continental Shelf.
- Use unconventional fossil fuels, such as oil shales and oil sands.
- Develop more efficient ways to use fossil fuels, such as coal
gasification.
- Diversify the energy supply to include alternatives to fossil
fuels, such as wind and solar energy.
- Promote a culture of conservation, finding “energy-efficient
solutions for transportation, buildings, homes and factories that
reduce consumption without compromising economic development.”
Like BP, Hofmeister said, Shell is exploring alternatives to
fossil fuels, such as biofuels, solar, wind and hydrogen. When oil
sold for around $10 a barrel in 1998, investment in these
alternatives was not economical. Today’s much higher oil prices, he
noted, have made alternative fuel projects viable.
“We have an obligation,” Hofmeister concluded, “to pass on to future
generations the energy security we’ve known for most of the last
century.”
Global Resource Assessment
Hofmeister’s talk was followed by panels on the global sources of
energy and public policy as it relates to energy security.
William L. Fisher, former dean of the Jackson School and the
Leonidas T. Barrow Centennial Chair in Mineral Resources, laid out
the statistical case for a global transition to a hydrogen economy
by mid-century.
The intermediate phase to hydrogen is a methane economy, explained
Fisher. Dependence on oil will decline over the next 30 years as
natural gas becomes increasingly prominent as a source of fuel and
hydrogen for fuel cells. Around mid-century, methane will peak and
give way to hydrogen as the dominant energy source.
In the near-term, Fisher foresees adequate petroleum reserves to
meet global demand for oil. Despite expanding demand, new capacity
will come online from a combination of existing conventional and
non-conventional hydrocarbon reserves, new discoveries, and reserves
that become recoverable due to technological innovations.
“We have adequate resources to carry demand for oil into the methane
economy, and to sustain us into development of a hydrogen economy,”
said Fisher.
Nuclear Success
Sheldon Landsberger, coordinator of the university’s Nuclear and
Radiation Engineering program and a professor in the College of
Engineering, forecast increased global and national reliance on
nuclear energy.
The U.S. currently generates 20 percent of its electricity from
nuclear power plants compared to 16 percent globally, said
Landsberger. He credited the U.S. Nuclear Regulatory Commission for
marshalling dramatic improvements in safety over the past 15 years.
Equally significant has been support from environmentalists like
Patrick Moore, co-founder of Greenpeace, who praised nuclear energy
in a recent Washington Post op-ed as “the only large-scale,
cost-effective energy source that can reduce [greenhouse gas]
emissions while continuing to satisfy a growing demand for power.”
“When one of the leading anti-nuclear groups issues a pro-nuclear
endorsement,” said Landsberger, “you know things have changed. Even
Al Gore himself said that perhaps we should be thinking about
nuclear development.”
Conservation & Efficiency
Conservation represents another critical element in the path toward
energy security, contended David Allen, director of the Center for
Energy and Environmental Resources and the Melvin H. Gertz Regents
Chair in Chemical Engineering.
Historically, the world has taken decades to change its fuel
dependencies. As societies slowly shift from dependence on
hydrocarbons, said Allen, “Energy efficiency and conservation offer
some of the most effective solutions for reducing energy demand and
the environmental impacts of energy use.”
Allen believes that large improvements can come from changes in
consumer behavior. He noted that between the first Arab oil embargo
of 1973 and the mid-1980s, energy use per dollar of GDP in the U.S.
declined by a third. Since then, energy use has only declined
slightly.
“I would use this as evidence,” said Allen, “that we can do better
at efficiency and conservation.” To that end, Allen would like to
see The University of Texas at Austin become a national center for
energy education.
Reducing Greenhouse Gases
Ian Duncan, associate director for environmental programs at the
Bureau of Economic Geology, explained another tool that could both
enhance U.S. energy security and reduce greenhouse gas emissions:
carbon sequestration. Carbon sequestration is the capture and
storage of carbon dioxide (CO2) and other greenhouse gases that
would otherwise be emitted to the atmosphere.
Worldwide efforts to pioneer sequestration have focused on taking
point-source emissions from coal-fired power plants, which emit CO2
in high enough concentrations to warrant large-scale capture.
Carbon sequestration could enhance U.S. energy security, since
development of clean-coal technologies could encourage use of the
abundant resource and lessen U.S. dependence on foreign sources of
oil and gas. The U.S. has large coal reserves, said Duncan, with 50
percent more potential BTUs stored in coal than the Middle East has
stored in oil.
Geologically and industrially, Texas appears ideally situated to
help reduce greenhouse gases through clean-coal technologies. Its
industrial plants are responsible for about 1 gigaton of the 24
gigatons of CO2 emitted worldwide, said Duncan. At the same time,
its geological structures are among the world’s best for
sequestering CO2.
“Texas is a huge part of the problem but we can also be a big part
of the solution,” he said.
Duncan and colleagues at the Bureau of Economic Geology are leading
the first research-oriented carbon sequestration program in the
world. The Bureau of Economic Geology also leads the State of Texas
bid to develop FutureGen, a $1 billion public-private partnership
sponsored by the U.S. Department of Energy that will use coal to
generate electricity, produce hydrogen and capture and store carbon
dioxide.
Implications for Policy
On the policy front, Charles Groat, director of the university’s
Center for International Energy & Environmental Policy, sounded a
cautionary note about efforts to change public perceptions about
long-term energy and environmental issues.
He cited a case study where residents of coastal Louisiana were
confronted with projections showing that climate-driven sea-level
change could put all of Interstate Highway 10 under water. Despite
the projections, people expressed more concern about poverty, losing
regional businesses, and bad government than climate change.
“On the face of it, something that did not happen (sea-level change)
did not have much impact,” said Groat. To arouse public awareness,
“the immediacy level is critical,” said Groat.
He believes efforts at radical change to shift to non-hydrocarbon
sources of energy may be well intentioned but are not well informed
because “we are with fossil fuels” for the foreseeable future.
Groat thinks that moves toward reducing CO2 will need to rely not so
much on switches to non-CO2-emitting technologies as on reducing the
generation of CO2 from current methods of energy production.
Eugene Gholz, assistant professor at the LBJ School, advocated a
U.S. policy shift toward increased taxes on imported oil for
economic security reasons. Gholz believes such an investment could
lessen demand for imported oil, with revenues used to spur
investments in alternative energy supplies.
He acknowledged that politically the idea of raising these taxes “is
a non-starter, but it’s the idea we ought to talk about.”
Michael Webber, associate director for program development at the
Center for International Energy & Environmental Policy, regaled the
audience by debunking energy myths that relate to public policy.
“Everyone says it’s China’s fault,” said Webber, referring to the
widely touted belief that increased Chinese demand is behind rising
oil prices. “Chinese demand for oil has gone up three million
barrels a day,” acknowledged Webber. “What we’re not told is ours
has gone up by three million barrels a day too. Somehow that gets
left out.”
Webber expressed belief in the power of markets to rectify the U.S.
energy situation, but he thinks it will not “happen by accident, and
we need political leadership,” and a more informed public.
