Direct Air Capture (DAC) Siting and Modeling
DAC technology siting and performance assessment using NECTAR, the Negative CO2 Emission Transition Roadmap.
Optimizing site selection and design for DAC technology
Using proprietary NECTAR software and its comprehensive supporting database, Carbon Solutions identifies optimal sites for DAC deployment. This includes evaluating technology performance based on hourly climate, elevation, CO2 storage potential, renewable energy availability, and other critical factors. In addition to site suitability, NECTAR analyzes resource use, including water consumption and energy demand, ensuring that sites are not only technically feasible but also resource-efficient. NECTAR is designed to maximize CO2 capture efficie storage potential, renewable energy and power availability, and other factors. NECTAR aims to maximize CO2 capture while minimizing energy needs and costs.
Our Process
Novel approach to DAC siting and assessment
DAC technology performance
Power availability focused on renewables
We use NECTAR to calculate power availability and cost (on and behind meter) with a focus on renewables including wind, solar, and geothermal.
CO2 storage assessment
Using SCO2TPRO, Carbon Solutions identifies CO2 storage sites by evaluating injection rates, plume evolution, storage capacity, and sequestration costs.
Integrated DAC Assessment
NECTAR
Our proprietary DAC siting tool
Example considerations
- DAC performance as a function of weather, including variability, extremes, and risk to facility uptime
- Quantity, source, and carbon footprint of energy required (e.g., heat, steam, electricity)
- Renewable energy availability and integration (e.g., solar, wind, geothermal)
- Long-term weather risks, such as increased frequence of extreme events or shifting climate patterns
Current technologies of focus
- High-temperature, liquid solvent, direct air capture
- Low-temperature, solid sorbent, direct air capture
FAQs
Learn more about Direct Air Capture (DAC) and how it can benefit your organization.
What are the benefits of Direct Air Capture (DAC)?
DAC is a Carbon Dioxide Removal (CDR) technology that captures CO2 directly from the air. Unlike other approaches, DAC requires minimal land and enables straightforward measurement of captured CO2, making it efficient and scalable.
What DAC technologies do you work with?
Carbon Solutions works with multiple DAC technologies, including solid sorbents and liquid solvents. NECTAR’s siting and modeling process is adaptable to any technology with available performance data.
How do you work with environmental constraints in DAC?
Environmental factors, such as weather, water consumption, energy availability, and CO2 storage, can be individually or collectively analyzed. This flexibility allows Carbon Solutions to customize its approach to align with client priorities.
How do you determine where DAC potential is best?
NECTAR uses a data-driven framework to evaluate weather conditions, energy access, CO2 storage potential, natural resource requirements, and environmental justice considerations, enabling informed and optimized site selection.
How does NECTAR fit into your process?
NECTAR plays a central role in DAC feasibility assessments by combining technical, economic, and societal considerations. Its comprehensive framework provides highly accurate and tailored results without requiring customers to disclose proprietary technology details, ensuring privacy while identifying the best locations and technologies for specific project goals.
