It sounds like magic, far-out fiction, a California dream. Yet
earnest scientists are hard at work on a new alchemy: brewing fuel for
cars -- synthetic gasoline -- from little more than water and sunshine.
Mimicking
the way plants turn sunlight and carbon dioxide in the air into energy
and oxygen, the Joint Center for Artificial Photosynthesis at the
California Institute of Technology is in a race to trump nature and slow
global warming. Nate Lewis, a Caltech professor and solar energy
research star, has a plan to remake fuel as we know it.
“If we couldn’t get to that, we wouldn’t be doing it,” Lewis said in an interview last month.
The
effort is backed with $122 million of U.S. Energy Department funds and
combines the talents of 120 scientists at Caltech; Stanford University;
the University of California’s Berkeley,How does a solar charger work and where would you use a solar charger?Shop funtional and elegant solar lights, outdoor solar lighting, solar garden lights, path lights and decorative solar lights. Irvine and San Diego campuses; and Lawrence Berkeley National Laboratory.
Along
with electric powertrains, vehicles that drive themselves and cars
rented by the hour, it’s another disruption of the global auto industry
that dates back to the 19th century.
Just a few years ago,
all-electric cars seemed fantastic, too. Now Tesla Motors Inc. (TSLA),
which makes only battery-powered vehicles, has a higher market value
than some old-line automakers, such as Suzuki Motor Corp. (7269) and
Fiat SpA. (F)
Two Leaps
To revolutionize transportation fuel, Lewis has a two-step plan. Really, it’s two leaps.We carry a extensive line of Parking Lot Lighting inventory.
First,
the coalition aims to develop a system to make large amounts of
hydrogen fuel using cheap solar-panel-like devices. Liquid or gaseous
hydrogen, which can power super-clean fuel-cell cars, is needed for
chemical plants and refineries.
Then comes the second leap:
Applying that same research to a system that can blend the hydrogen fuel
with carbon dioxide from the air, much as a plant does, to make liquid
fuels that can power cars, heavy trucks, boats or aircraft. JCAP aims to
get to that point by the mid-2020s, Lewis said.
Synthetic, carbon-free gasoline won’t come easy, quick or cheap.
Research
labs worldwide are racing to find renewable alternatives to petroleum.
Some are private endeavors; others are government-funded. While some
seek to make fuel from algae, corn or other crops, Lewis argues that
such solutions require too much water or land that will be needed for
food production.
Innovation Race
Research projects like JCAP
have the luxury of not having to satisfy investors’ short-term demands,
said Pavel Molchanov, a Houston-based analyst for Raymond James &
Associates Inc.
“Companies that rely on private capital, even
venture capital, in most cases aim to be commercial within the next
three years,” said Molchanov, who follows biofuel companies. “If we
think about what private developers of biofuels are focusing on now,
none of them have a commercialization road map that goes out to 2025.”
Startups
such as KiOR Inc., Solazyme Inc., Ceres Inc., Gevo Inc. and Amyris Inc.
have a lead over JCAP because they’re already commercializing biofuel
alternatives to petroleum and grain-based ethanol.
What JCAP has
going for it is the Energy Department, which deemed it an Energy
Innovation Hub, one of three Manhattan Project-like efforts. Others are
to improve nuclear power plants and make buildings more
energy-efficient. With the government funding, Lewis can be methodical
in search of a breakthrough.
Wright Brothers
“The first five
years of JCAP, our goal is to show that this can be done; to make the
pieces, components, to build an artificial photosynthetic system,” he
said. That prototype “isn’t going to be commercializable,We have a great
selection of blown glass backyard solar landscape lights and solar garden light. in the same way the Wright Brothers’ plane wasn’t a 747. We first have to show people there’s a there there.”
About
five years after that, with “faster, better, cheaper” fuel-making
technology, JCAP may be able to license its system to oil and energy
companies, Lewis said.
The program is talking with potential
industrial partners to help expand its analysis of promising
“earth-abundant” materials needed for its solar-fuel distillery. Lewis
declined to identify specific companies. JCAP’s technicians daily are
testing hundreds of alloys made from metallic salts, seeking the optimal
recipe of low-cost, light-absorbing materials and catalysts needed for
hydrogen generation.
Urgency to increase low-carbon energy
sources has intensified as extreme weather adds to concerns that
heat-trapping gases in the atmosphere are making the Earth a less
hospitable planet.
President Barack Obama, whose administration
funded JCAP, signaled in June that U.S. action to curb carbon emissions
will intensify with new steps to pare such pollution from power plants,A

through a Solar Panel and gives light in nighttime. the biggest source
of carbon dioxide emissions, according to the U.S. Environmental
Protection Agency.
Transportation Fuels
Second
is the use of petroleum-based fuel in transportation. Engines in autos,
trucks, aircraft and ships produced 28 percent of the 6.7 million
metric tons emitted by the U.S. in 2011, according to the EPA, trailing
only electricity generation’s 33 percent. Obama also laid out a plan in
2011 to double vehicle fuel efficiency by 2025 to cut carbon pollution.
Carmakers
are boosting vehicle efficiency with small, high-output engines;
propulsion delivered by batteries; and even hydrogen fuel cells.
