Caterpillar expands range of H2-fueled power solutions

Caterpillar announced the latest additions to its lineup of commercially available power solutions running on H2 fuel. Available at Cat dealers worldwide, Caterpillar’s lineup of gas generator sets capable of operating on natural gas blended with up to 25% H2 by volume now includes power nodes ranging from 600 kW to 2.5 MW for 50 or 60 Hz continuous, prime, and load management applications. These include Cat CG132B and Cat CG170B generator sets as well as the G3500H series platform.

Additionally, the company offers aftermarket retrofit kits for updating select G3500H series platform products to provide the same H2 blending capabilities of up to 25% H2 by volume.

These new generator sets add to Caterpillar’s current portfolio of H2-capable power solutions. Since last year, Caterpillar has offered demonstrator Cat G3516 gas generator sets capable of operating on 100% H2. It is available with a maximum rating of 1250 kW for 50 or 60 Hz continuous applications.

“By expanding our portfolio of generator sets using H2 blends, we’re allowing more of our customers to evaluate the performance and sustainability of H2-fueled power solutions in their operations,” said Bart Myers, general manager for Caterpillar Large Electric Power. “This program also provides additional options to help customers navigate the energy transition through future-proof systems that can be readily configured for pipeline natural-gas blending.”

The new generator sets show how Caterpillar continues to invest in H2-fueled power technologies that minimize impacts on maintenance costs and schedules, availability and operations.

Last year, Caterpillar announced a project with District Energy St. Paul to demonstrate a 2.0 MW combined heat and power (CHP) system fueled by various combinations of H2 and natural gas. The project is supported and partially funded by the U.S. Department of Energy (DOE), and it is backed by the National Renewable Energy Laboratory (NREL).

Also, Caterpillar has launched a three-year project through a collaboration with Microsoft to demonstrate a power system incorporating a large-format H2 fuel cell to produce reliable and sustainable backup power for data centers. The project is supported and partially funded by the DOE under the H2@Scale initiative, and it is backed by the NREL.

These initiatives build on Caterpillar’s 35 years of enterprise experience in H2 fuels, supporting numerous power generation projects across multiple end industries currently operating on natural gas blended with up to 80% H2.

In addition to its H2 power initiatives, Caterpillar is actively contributing to a reduced-carbon future through continued investments in new products, technologies and services. These include Distributed Energy Resource Management System (DERMS) software solutions for monitoring, managing, and monetizing on-site energy assets; a full hybrid energy solutions technology suite; Cat cogeneration CHP systems and combined cooling, heat and power (CCHP) systems; and support for hydrotreated vegetable oil (HVO), biodiesel and blended fuel products.
