**Princeton, NJ** – New research from Princeton University suggests that sharing carbon capture, transport, and storage infrastructure across multiple industrial facilities could significantly reduce costs and environmental impacts associated with carbon dioxide (CO2) emissions.
The study, published in Environmental Science & Technology, focused on Louisiana, which has a high concentration of industry and favorable geological conditions for underground CO2 storage. Researchers found that shared infrastructure could cut costs by over 60% and reduce pipeline construction by more than 75% compared to individual facilities building their own pipelines.
“The challenge with carbon capture and storage is who should pay the added costs,” said co-author Eric Larson, senior research engineer at Princeton’s Andlinger Center for Energy and the Environment. “It’s a question of economics rather than technical feasibility.”
The research team modeled optimal carbon capture networks, highlighting the advantages of shared infrastructure over single-user approaches. They also emphasized the potential for equitable distribution of infrastructure, minimizing its impact on historically disadvantaged communities.
“It’s entirely feasible to design pipeline networks to minimize the burden on communities that have borne many of the negative health and environmental impacts associated with living near CO2-emitting industrial facilities,” said lead author Tubagus Aryandi (Arya) Gunawan, a postdoctoral researcher at the Andlinger Center.
The study also identified opportunities for synergy with recent federal investments in clean energy hubs and carbon capture technology. For example, the Infrastructure Investment and Jobs Act of 2021 has funded the development of regional clean hydrogen hubs, which often involve significant carbon capture. The Inflation Reduction Act of 2022 provides tax credits for carbon capture, further incentivizing its adoption.
While sharing infrastructure offers significant cost savings and environmental benefits, the researchers acknowledge that economic considerations remain a challenge for many facilities. They are currently exploring the potential for sharing carbon capture plants themselves, which could lead to even greater cost reductions.
“Our underlying methodology is widely generalizable,” said Gunawan. “We believe that the findings from our study can be applied to any region of interest.”
This research provides valuable insights for policymakers and industry leaders seeking to reduce greenhouse gas emissions and build a more sustainable future. By exploring the potential of shared infrastructure, we can unlock the economic and environmental benefits of carbon capture technologies and pave the way for a cleaner, more equitable energy system.
