How industrial clusters can help the US reach its net-zero targets
Decarbonizing U.S. industry presents one of the toughest challenges in the fight against climate change. Heavy industry—from steel and cement to petrochemicals—produces emissions that are difficult and costly to eliminate. Unlike power generation, where renewable energy and efficiency measures have proven effective, these “hard-to-abate” sectors require innovative approaches to reduce carbon without jeopardizing economic competitiveness. Industrial clusters have emerged as a strategic solution, offering a pathway to decarbonize while maintaining domestic manufacturing jobs and preventing carbon leakage.
Industrial clusters are geographically concentrated zones where multiple heavy industries share infrastructure to manage emissions. Examples include the Texas Gulf Coast, Louisiana, and the Ohio Valley. By pooling resources, these clusters allow industries to achieve efficiencies that would be impossible for individual facilities. The cluster model represents the most economically sensible and scalable way for the U.S. to tackle its industrial emissions, particularly in sectors where standalone decarbonization is prohibitively expensive.
One of the core advantages of clusters is the ability to share infrastructure for carbon capture, utilization, and storage (CCUS). Installing CCUS at a single plant is costly, with individual pipelines, compressors, and storage sites representing a massive financial burden. Within a cluster, multiple refineries, cement factories, and chemical plants can jointly invest in a single, large-scale CO₂ trunk pipeline that transports emissions to a central geological storage site. This shared approach significantly reduces the cost per ton of captured carbon and allows dozens of facilities to participate simultaneously. The economies of scale make decarbonization feasible where it would otherwise be impossible.
Clusters also provide a backbone for clean hydrogen production. Hydrogen hubs, supported by federal investment, enable centralized generation of low-carbon hydrogen, either green or blue. Shared pipelines then distribute hydrogen to diverse users across the cluster, including steel mills, power plants, and petrochemical facilities. By replacing high-carbon fuels like coal and natural gas, hydrogen hubs reduce emissions while supporting operational flexibility across multiple industries.
Policy support is critical to these clusters’ success. Federal incentives, such as the enhanced $45Q tax credit for carbon sequestration and funding for hydrogen hubs, de-risk the massive infrastructure investments required. Public-private partnerships allow government funding to catalyze projects that might otherwise be too expensive to initiate. Beyond technology, these policies also aim to prevent carbon leakage—the relocation of production to countries with lower climate standards. Maintaining high-value domestic industries while meeting emissions goals ensures both economic competitiveness and progress toward net-zero targets.
Clusters also offer a path to a just transition for workers. By focusing on retraining existing unionized employees—engineers, pipefitters, and welders—for new roles operating and maintaining CCUS and hydrogen infrastructure, cluster development secures skilled, high-wage employment. This approach promotes long-term economic stability in industrial regions that might otherwise struggle with declining employment as traditional operations become more automated or emission-intensive processes are phased out.
Emerging U.S. clusters demonstrate the potential of this strategy. On the Gulf Coast, Houston and Louisiana host heavy petrochemical and refining industries, with access to extensive infrastructure and underground saline aquifers ideal for permanent CO₂ storage. In the Midwest and Ohio Valley, steel, cement, and general manufacturing corridors are being leveraged to decarbonize supply chains that feed the automotive sector, combining geographic advantage with industry-specific opportunities for emission reductions.
While the industrial cluster approach is complex and requires unprecedented cooperation between industry, government, and local communities, it offers the most viable path to decarbonizing the hardest-to-abate sectors. By pooling resources, sharing infrastructure, and integrating clean energy solutions like CCUS and hydrogen, these clusters can deliver meaningful reductions in emissions without sacrificing jobs or economic competitiveness. The success of U.S. climate commitments in heavy industry may well depend on the effectiveness and scale of these emerging industrial clusters, shaping the future of both the economy and the environment.
