Taking a Critical Step Towards Net Zero Emissions Using Carbon Sequestration
The picturesque California Delta, often referred to as the Sacramento-San Joaquin Delta, is emerging as a geological sweet spot in California’s ambitious journey toward reaching net zero carbon emissions. Its unique geology presents a compelling case for carbon sequestration, an essential strategy in the battle against climate change. Recent developments, including a collaborative effort between SCS and Lawrence Livermore National Laboratory (LLNL) on a Class VI permit application for Pelican Renewables – a company formed by Delta landowners and residents to pursue geologic storage – are indicative of the region’s growing importance in California’s carbon mitigation strategy.
Geological Foundations of Carbon Sequestration in the California Delta
The California Delta, often referred to as the Sacramento-San Joaquin Delta, is a vast inland delta formed by the confluence of the Sacramento and San Joaquin rivers and their tributaries as they meet the waters of the San Francisco Bay. Its unique geology makes it an ideal candidate for carbon sequestration:
California’s Net Zero Carbon Goal and Carbon Sequestration in the Delta
California has set an ambitious goal to achieve net zero carbon emissions by 2045, a milestone in the fight against climate change. Achieving this objective necessitates reducing emissions and actively removing and storing carbon from the atmosphere. Carbon sequestration in the California Delta can play a pivotal role in this endeavor. The Delta’s geological potential aligns seamlessly with the state’s commitment to sustainable practices and environmental responsibility.

Capturing carbon and injecting it into a carbon sequestration well, also called a Class VI Well, is an EPA-approved technology. Manufacturers and industries are considering using carbon sequestration to reduce greenhouse gas emissions (CO2). Often, the public is concerned that carbon injection wells could contaminate underground drinking water — a legitimate concern, given today’s headlines. In this environmental engineering blog, we’ll describe the two ways underground drinking water could be contaminated and how to prevent it.
Contamination can occur if the CO2 can migrate up the well bore into the aquifer anytime after injection. The second instance is if pressure forces the brine from the injection zone into the aquifer.
Environmental engineering teams, which include professional geologists, hydrogeologists, and geoscience experts, take steps and provide well-operators guidance to protect drinking water sources, including calculating the Area of Review (AOR) around the injection well and computational modeling to understand how the pressures can build up during injection to create unsafe conditions.
Armed with expert knowledge and more modeling accuracy, operators can prevent contamination, extend the life of carbon sequestration wells, and address public concerns.
Dr. Charles Hostetler explains in the SCS educational video how accurately calculating the AOR and understanding critical pressure work together so companies can confidently use carbon capture and sequestration to reduce greenhouse gas emissions safely.

Many companies are exploring carbon capture and sequestration (CCS) to help reach greenhouse gas emission reduction goals. Protecting aquifers is a primary concern for the public to safeguard underground drinking water sources. Starting with near-surface background environmental monitoring is the first step to addressing public concerns and maintaining safety.
A comprehensive monitoring plan helps preserve the safest conditions and can save time and expense during injection and post-closure care. This SCS Engineers webinar explains the concepts, how it protects aquifers, and what to look for in a background monitoring plan. Establishing baseline conditions before injection is the first step. Starting immediately after submitting the Class VI permit application, during the regulatory technical review period provides the time to take these important baseline measurements.
Dr. Charles Hostetler, with nearly four decades of experience as an engineer and hydrogeologist protecting aquifers, explains why near-surface monitoring is important to meet demands for addressing environmental concerns during the design and operation of a CCS project. His expertise helps protect aquifers and save time during the design, build, and operation of CCS wells through closure.

Helpful Basic Tips:
Early planning and mindful project scoping are critical for a CCS project to understand and communicate the project’s needs, objectives, goals, and conceptualized design. Use site characterization data and have a good handle on the operational parameters to develop a good first model and initial area of review delineation. The monitoring system design should then be tailored based on those data. Use the baseline and operational monitoring data to calibrate the model and refine your area of review delineation.
Early financial planning is also important and should include long-term operations and monitoring. Spend rates will be variable throughout these projects and highly dependent on the project’s phase.
The site geology is a key factor — we highly recommend conducting a feasibility study before beginning a project to assess the suitability of Class 6 injection at the proposed location. In addition, when the permit process begins, it’s important to front-load the site characterization efforts to minimize the uncertainty surrounding your site suitability.
Proactive stakeholder engagement surrounding your project is more likely to help lead your project to success. Developing outreach plans help open and facilitate lines of communication with stakeholders, regulatory officials, and public and environmental advocate groups.
Use an iterative project approach – permitting is not a cookie-cutter but a site-specific process. Your early and thorough planning steps help create a feedback loop that will go on throughout the project’s life. It enables flexibility in implementing your approach.
