Cat moves into hydrogen

By Jack Burke01 September 2021

Retrofit kits coming in 2022, company says

Caterpillar will begin offering Cat generator sets capable of operating on 100% hydrogen, including fully renewable green hydrogen, on a designed-to-order basis in the fourth quarter of 2021.

Additionally, later this year Caterpillar will launch commercially available power generation solutions from 400 kW to 4.5 MW that can be configured to operate on natural gas blended with up to 25% hydrogen.

These innovations leverage power generation projects currently operating on natural gas blended with up to 80% hydrogen to help address customers’ carbon-reduction goals with high-performing, cost-effective technologies that demonstrate the near-term viability of hydrogen as a fuel source, Caterpillar said in a news release. Building on 35 years of experience across multiple end markets, Caterpillar continues to improve the performance of hydrogen-fueled power technologies with minimal impacts on maintenance costs and schedules, availability and operations.

Caterpillar announced the introduction of a wide-ranging selection of power solutions that operate on a range of hydrogen fuels.

“The power solutions landscape is transforming as customers look to maximize the environmental and economic benefits of reducing their carbon intensities,” said Bart Myers, general manager for Caterpillar Large Electric Power. “We’re extending our leadership through numerous initiatives that demonstrate the viability of power solutions that can utilize many types of hydrogen, including fully renewable, in order to shorten the path to commercial availability.”

New Caterpillar Hydrogen Fuel-Capable Electric Power Offerings

In the fourth quarter of 2021, Caterpillar will begin offering the Cat G3516H gas generator set specifically configured to use 100% hydrogen for fuel. Initially available as demonstrator units in North America and Europe with initial deliveries in late 2022, the Cat G3516H generator set will be offered with a rating of 1250 kW for 50 or 60 Hz continuous, prime, and load management applications.

Later this year, Caterpillar will also begin a staged roll-out of commercially available Cat CG132B, CG170B, G3500H, G3500 with Fast Response, and CG260 gas generator sets configured to enable operation on natural gas blended with up to 25% hydrogen for continuous, prime, and load management applications in North America and Europe. Additionally, the company will offer retrofit kits that provide hydrogen blending capabilities up to 25% hydrogen for select generator sets built on these engine platforms. Production of new natural gas generator sets and retrofit kits capable of 25% hydrogen will begin in the fourth quarter of 2022.

Plans for operating on 100% hydrogen include developing a range of commercially available products and upgrades for existing Cat gas generators. The company said the development and launch of these solutions address potential customer demand growth as the hydrogen supply infrastructure matures, and these initiatives demonstrate Caterpillar’s comprehensive, wide-ranging commitment to helping customers meet their climate-related objectives.
