A handful of carbon capture projects with Houston ties are on the receiving end of more than $7 million in federal stimulus funds, part of the first round of the Department of Energy’s $1.4 billion piece of the American Recovery and Reinvestment Act funds. The companies are required to put up matching funds.
The projects include:
The many way of injecting CO2 subsurface for storage.
• Air Products and Chemicals Inc. will design, construct and operate a system to concentrate CO2 from two steam methane reformer waste streams at a Port Arthur, Texas facility, and move more than one million tons of the CO2 via pipeline for sequestration into the Oyster Bayou oilfield (across Galveston Bay in Chambers County) for enhanced oil recovery by Denbury Onshore. DOE Share of the project: $961,499.
• CEMEX USA, the Houston-based, U.S. arm of the Mexican cement giant, will partner with RTI International to demonstrate a dry sorbent CO2 capture technology at one of its cement plants. The project is aimed at removing up to one million tons of CO2 per year. DOE funds: $1,137,885.
• ConocoPhillips will demonstrate improvements in conversion efficiency and economies of scale for carbon capture systems at a 683-megawatt power plant next to its refinery in Sweeny that runs on petroleum coke, a refining byproduct. About 85 percent of the CO2 from the process stream will be captured and over five million tons sequestered into a depleted oil or gas field. DOE funds: $3,014,666.
• Leucadia Energy will partner with Denbury Onshore to demonstrate technology to capture and sequester more than 4 million tons of CO2 emissions at a Lake Charles, La. co-generation petroleum coke-to-chemicals (methanol) project. The CO2 will be transported through a 12-mile pipeline to Denbury’s Green Line pipeline system that will bring CO2 for enhanced oil recovery in the Hastings and Oyster Bayou oilfields in Texas. DOE funds: $540,000.
• Praxair partners with BP, Denbury Resources and the Gulf Coast Carbon Center to demonstrate CCS of emissions from an existing hydrogen-production facility in BP’s Texas City refinery into underground formations for enhanced oil recovery. The project includes a lateral pipeline to connect to Denbury’s Green Pipeline to transport one million tons of CO2 per year. DOE funds: $1,719,464.
