The first-of-its-kind plant would test the theories surrounding
carbon-sequestration as a solution to the emissions currently escaping
fossil fuel-based power plants all across the U.S. and countries beyond.
Somewhat like the gases captured at east coast landfills for power
production, this project would use the vast byproducts of an oil refinery
to provide commercial power generation from the relatively clean
combustion of hydrogen while also separating and sequestering the CO2. The
following paragraphs are drawn directly from a BP press release.
The plant would be located alongside BP's Carson refinery, about 20 miles
south of Los Angeles, and would be capable of producing 500 MW of
"low-carbon" generation, enough power to serve 325,000 Southern California
homes.
BP and EMG hope to complete detailed engineering and commercial studies in
2006, finalize project investment decisions in 2008 and bring the new
power plant online by 2011.
The proposed Carson project would combine a number of existing industrial
processes to provide a new option for generating electricity without
significant CO2 emissions. Petroleum coke produced at California
refineries would first be converted to hydrogen and CO2 gases and around
90 percent of the CO2 captured and separated. Petroleum coke is a residue
produced when all useful volatile hydrocarbons are removed from crude oil
in the refining process. Carson refinery's coker units produce around 3 to
4,000 tons of coke a day.
The hydrogen gas stream would be used to fuel a gas turbine to generate
electricity. The captured CO2 would be transported by pipeline to an
oilfield and injected into reservoir rock formations thousands of feet
underground, both stimulating additional oil production and permanently
trapping the CO2.
"This will be the first plant of its kind in the whole country and I think
it is a perfect fit for our state," said California Governor Arnold
Schwarzenegger, speaking at the announcement in Carson. "With our
Strategic Growth Plan, a commitment to air quality, and innovative
projects like this hydrogen plant, I know we can have clear skies, improve
our quality of life and build a stronger, more vibrant economy for
California."
Final project investment decisions will follow further study by the
partners and review by the California Energy Commission and the South
Coast Air Quality Management District. BP and EMG are beginning project
discussions with state and federal government agencies and local
stakeholders and are exploring options for selling the electricity the
plant would generate. BP is in discussions with Occidental Petroleum to
develop options for sequestering the CO2 in Occidental's California
oilfields.
The costs of hydrogen power are higher than those of traditional power
plant fuels. As a result, the project will depend, in part, on incentives
provided in the Federal Energy Policy Act of 2005 for advanced
gasification technologies. In addition, continued progress on the
California Public Utilities Commission's electricity "resource adequacy"
procurement policies will encourage this first-of-its-kind facility.
"Wide-scale deployment of technology such as hydrogen power can make a
significant contribution towards the reduction in greenhouse gas emissions
needed worldwide," said Ross Pillari, president of BP America. "California
is a natural location for this project. Both the state and federal
government have challenged businesses to take a leadership role in
tackling carbon dioxide emissions. With this project, we expect to make a
meaningful contribution to those goals."
Large scale Hydrogen combustion contributes enormously towards the inherently greater problem of oxygen depletion of the atmosphere. Hydrogen combustion reduces the atmospheric content of oxygen and replaces it with water vapor. Without adding oxygen to the atmosphere during the production process of Hydrogen for combustion, atmospheric oxygen is depleted. Reprocessing carbon based fuels to generate hydrogen is generally a path towards oxygen depletion.
Electrolysis with energy from green sources in conjunction with releasing the associated oxygen particles guarantees a net zero affect on the oxygen content of the atmosphere.
As oxygen is required for most life forms depletion is not an acceptable large scale process.
