SoCalGas and the Pacific Northwest National Laboratory Announce U.S. Department of Energy Funding of Carbon Capture Project
Project will use the captured CO(2) to produce methanol
Nov 25, 2019
LOS ANGELES, Nov. 25, 2019 /PRNewswire/ -- Southern California Gas Co. (SoCalGas) and the Pacific Northwest National Laboratory (PNNL) today announced the U.S. Department of Energy (DOE) has awarded $300,000 in funding to a project that would advance the development of a process called Integrated CO2 Capture and Conversion to Methanol (ICCCM). Carbon capture and utilization (CCU) projects are an important component in helping California achieve its climate goal of having a "net zero" economy by 2045. CCU projects harnesses carbon before it can be emitted into the atmosphere. The carbon is then typically used to make chemicals that become resins and plastic materials.
The DOE funding for this project will be used to design, fabricate and demonstrate a modular ICCCM prototype for the combined capture and conversion of CO2 into methanol. As part of the research, the commercial viability of the prototype will also be assessed. The unit will be designed for installation at an industrial CO2 source, such as an electric generation or anaerobic digestion facility.
SoCalGas is committed to helping California achieve its ambitious climate goals. The utility has spent more than $10 million on the research and development of low or zero carbon technologies in the last three years.
"As we look for ways to reduce greenhouse gas emissions in support of the state's climate goals, we will need to develop cost-effective technologies that can capture and use CO2 to prevent it from reaching the atmosphere," said Yuri Freedman, senior director of business development for SoCalGas. "The goal of this project is to determine whether ICCCM technology can be a cost-effective way to reduce emissions and it is our hope the results will show that it is."
"At PNNL, we specialize in carbon capture and catalysis research and are thrilled to be collaborating with SoCalGas on developing a new and innovative capture and conversion technology and deploying this technology into the field," said Dr. David Heldebrant, who is co-leading this project and is PNNL chief scientist for separations materials. "Our role in this project is to design a continuous catalytic process that can take waste CO2 and repurpose it as a low carbon fuel or chemical feedstock with a large market size, such as a methanol."
What is ICCCM
The ICCCM technology is unique because hydrogen is used as an indirect energy source to drive the carbon capture process rather than steam or electricity. Also, by using the ICCCM solvent to directly convert CO2 to methanol, no mechanical compression of the CO2 is required. Typically, compressing CO2 is energy-intensive, so reducing the need for additional energy inputs makes the ICCCM technology a potentially viable solution to capture and convert CO2 from landfill gases, wastewater treatment gases and manure off-gas.
California has set an ambitious goal of having a net zero economy by 2045, meaning the amount of carbon emitted into the atmosphere is no more than the amount of carbon taken out. While carbon neutrality is a good first step, research continues into finding ways to be carbon negative, i.e. remove more carbon from the atmosphere than is produced. One potential way to do this is to use green hydrogen created from renewable energy such as wind or solar is used in carbon capture and utilization.
Over the next two years, this project will evaluate the compatibility of certain catalysts and solvents, design and build the reactor and test the unit. The later stages of this research will also assess the viability of producing polycarbonates.
Headquartered in Los Angeles, SoCalGas® is the largest natural gas distribution utility in the United States. SoCalGas delivers affordable, reliable, clean and increasingly renewable natural gas service to 21.8 million customers across 24,000 square miles of Central and Southern California, where more than 90 percent of residents use natural gas for heating, hot water, cooking, drying clothes or other uses. Natural gas delivered through the company's pipelines also plays a key role in providing electricity to Californians— about 45 percent of electric power generated in the state comes from gas-fired power plants.
SoCalGas' vision is to be the cleanest natural gas utility in North America, delivering affordable and increasingly renewable energy to its customers. In support of that vision, SoCalGas is committed to replacing 20 percent of its traditional natural gas supply with renewable natural gas (RNG) by 2030. Renewable natural gas is made from waste created by dairy farms, landfills and wastewater treatment plants. SoCalGas is also committed to investing in its natural gas system infrastructure while keeping bills affordable for our customers. From 2014 through 2018, the company invested nearly $6.5 billion to upgrade and modernize its natural gas system to enhance safety and reliability. SoCalGas is a subsidiary of Sempra Energy (NYSE: SRE), an energy services holding company based in San Diego.
