Caterpillar Inc. has announced a collaboration with District Energy St. Paul to showcase a 2.0 MW combined heat and power system running on hydrogen and natural gas. The project, backed by the U.S. Department of Energy, aims to assess the performance and emissions profile of hydrogen fuel in a real-world setting. Caterpillar will deploy a flexible-fuel system managed by the Cat Master Microgrid Controller, enabling comparisons between 100% hydrogen, natural gas, and hydrogen-natural gas blends. This initiative aligns with Caterpillar's efforts in hydrogen technology, offering hydrogen-capable generator sets and retrofit kits for blending hydrogen with natural gas. District Energy St. Paul, known for its sustainability efforts, targets carbon neutrality by 2050 and has achieved a 68% reduction in carbon emissions since 2000. They have integrated renewable energy sources like solar and biomass to achieve almost 50% carbon-free heat. Caterpillar's broader product portfolio, including investments in energy management solutions like Tangent Energy Solutions, underscores its commitment to sustainability and reduced emissions.
