Can PrISMa Save Our Planet? Inside the New Carbon Capture Phenomenon

PrISMa revolutionizes the field of carbon capture by combining insights from materials science, engineering, and economic analysis to predict the effectiveness of new technologies.

This innovative platform not only enhances the development of carbon capture solutions but also ensures their sustainability and economic viability, effectively closing the gap between laboratory research and practical implementation.

Mitigating the effects of climate change has become a major focus worldwide, with countries and international organizations developing various strategies to address the problem. Lowering CO₂ emissions is at the top, with carbon capture technologies being a promising way forward.

Nonetheless, bridging the gap between research and practical implementation of carbon capture solutions has proven so difficult, it has an actual name: “Valley of Death.” The challenge is compounded by the need to take into account the perspectives and priorities of different stakeholders along the process.

Innovating Carbon Capture With PrISMa

Traditionally, carbon capture tech development begins with chemists designing materials and engineers developing processes, while economic and environmental impacts are assessed later. The results are often suboptimal and only delay the implementation of real-world solutions.

In response to this, scientists led by Berend Smit at EPFL and Susana Garcia at Heriot-Watt University have developed the PrISMa (Process-Informed design of tailormade Sorbent Materials) platform: an innovative tool that seamlessly connects materials science, process design, techno-economics, and life-cycle assessment by taking into account multiple stakeholder perspectives from the outset.

Key Performance Indicators of PrISMa

PrISMa evaluates four Key Performance Indicators (KPIs), or “layers,” to assess the viability of a carbon capture material from its initial development to its implementation into a complete carbon capturing plant.

1. Materials Layer: Using experimental data and molecular simulations, the platform predicts the adsorption properties of potential sorbent materials.
2. Process Layer: PrISMa computes process performance parameters, such as purity, recovery, and energy requirements.
3. Techno-Economic Analysis Layer: PrISMa assesses the economic and technical viability of a carbon capture plant.
4. Life-Cycle Assessment Layer: PrISMa evaluates the environmental impacts over the plant’s entire life cycle, ensuring comprehensive sustainability.

Real-World Applications and Predictive Abilities

The scientists used PrISMa to compare over sixty real-world case studies, in which CO₂ is captured from different sources in five world regions with different technologies. By taking into account multiple stakeholder perspectives, PrISMa helped identify the most effective and sustainable solutions.

“One of the unique features of the PrISMa platform is its ability to predict the performance of new materials using advanced simulations and machine learning,” says Berend Smit. “This innovative approach accelerates the discovery of top-performing materials for carbon capture, surpassing traditional trial-and-error methods.”

Molecular Simulations Enhance Predictions

The platform integrates density functional theory (DFT) and molecular simulation to predict material properties needed for process design. The team tested this approach on a CO₂ capture plant looking at the indirect emissions over 30 years of the plant’s operation, and coupled this with a techno-economic assessment, which evaluated the cost of the process.

“We succeeded in connecting the movement of electrons at the DFT level to calculate the total amount of CO₂ captured over the 30-year lifetime of a capture plant, and at which costs,” says Berend Smit.

Stakeholder Insights and New Material Discovery

PrISMa provides invaluable insights for various stakeholders, offering engineers the tools to design the most efficient and cost-effective carbon capture processes, and guiding chemists on the molecular characteristics that enhance material performance.

Environmental managers gain access to comprehensive evaluations of environmental impacts, enabling more informed decision-making, while investors benefit from detailed economic analyses that reduce the risks and uncertainties associated with investing in new technologies.

Discovering New Materials

PrISMa can accelerate the discovery of top-performing materials for carbon capture, surpassing traditional trial-and-error methods. Its interactive tools allow users to explore over 1,200 materials, understanding the trade-offs between cost, environmental impact, and technical performance.

This comprehensive approach ensures that chosen solutions capture CO₂ efficiently while minimizing overall environmental impacts.

One way that Smit envisions PrISMa being used is in the discovery of metal-organic frameworks (DOI: 10.1038/s41586-024-07683-8
