Transportation and Storage

After the carbon is captured, the CO2 is compressed and transported via special underground pipelines, which have a long safety track record that surpasses that of other types of pipelines – an advantage recognized by the U.N. Intergovernmental Panel on Climate Change(1) The carbon is then injected thousands of feet below the water table, where it remains permanently trapped in underground rock formations. (2) To ensure the CO2 is successfully sequestered, scientists have perfected techniques for both environmental and deep subsurface monitoring. (3)

Community Safety

While all industry and manufacturing activity requires safety precautions, the specialized wells (EPA Class VI) used for geologic sequestration of CO2 have never had a single significant event posing a risk to local communities.(4) They are subject to strict permitting guidelines from the EPA and regulations require that all operators establish emergency remediation plans, detailed post-injection site care plans, and provide multiple opportunities for public input. As with all Calpine facilities, our team is committed to working with community-based organizations and residents to ensure our projects are built and operated in a way that addresses unique local concerns while delivering important benefits, including high-wage jobs and reliable, clean energy.

Climate Progress

Experts agree that CCUS technology will play a vital role in decarbonizing a variety of industrial activities, from generating electricity to manufacturing cement.(5) In the power sector, CCUS allows energy leaders like Calpine to provide low-carbon power 24 hours a day, seven days a week, no matter the weather. That baseload capacity serves as an ideal complement to intermittent or short-term energy sources like wind or batteries, ensuring the grid is both reliable and carbon-friendly. While some CCUS projects are designed to capture 50 or 60 percent of CO2 emissions, Calpine’s facilities are being designed to capture 95 percent of all CO2 emissions, standing by our commitments to the environment and our communities.

Air Quality

Our CCUS projects aren’t just designed to reduce emissions of greenhouse gases (GHG). Calpine always works with local communities to ensure our facilities are equipped with industry-leading technology to reduce traditional pollutants, like soot. In fact, the EPA has adopted a “best available control technology” (BACT) analysis conducted by Calpine as a case study in its guidance on other federal air permits.(6) Analyses like this guide Calpine’s principle of protecting air quality across our facilities.
