Kohler collaborated with Toyota on fuel cell power system

Kohler Power Systems, part of Kohler Energy, collaborated with Toyota Motor North America to develop and install a hydrogen fuel cell power generation system at the Klickitat Valley Health hospital in Goldendale, Washington. The fuel cell power system combines Kohler and Toyota technologies to showcase the viability of the zero-emission technology for power generation.

Leveraging decades of experience in energy systems, a Kohler-designed and manufactured controller will continuously monitor and manage operating conditions to harness the reliability, flexibility, and performance of the Toyota fuel cell as well as protect it from damage. The control system is extremely versatile and customizable, so Kohler can provide a system that functions precisely as the customer expects and interoperates with building-management systems (BMS).

Kohler will also complete the system integration and balance of plant to ensure all supporting components and auxiliary systems needed to deliver energy operate together safely and reliably and within a turnkey package.

Toyota has consolidated various components from a second-generation Toyota Mirai passenger vehicle fuel cell system into a single, compact fuel cell module. The newly created module includes the second generation’s improved fuel cell stack and the elements responsible for the generation of electricity (air containing oxygen and the gaseous hydrogen fuel), system cooling, and on-board power control. The module can be easily integrated and scaled into a variety of power plant applications.

The resulting new “KOHLER Fuel Cell System” is suited for prime, peak shaving, and emergency situations. The system can be scaled or customized by application to ensure the delivery of performance for the specific needs of customers, whether for individual installations or covering entire facility complexes.


Toyota has been exploring various applications of our fuel cell technology and this opportunity with Kohler highlights the decarbonization opportunities that hydrogen as a fuel can provide for customers. Our fuel cell technology can be scaled and used to power a wide variety of products beyond transportation, and it does so without any emissions except water.

—Chris Yang, Group Vice President, Business Development, Toyota

The first KOHLER Fuel Cell System will be installed at Klickitat Valley Health, a hospital that serves as the principle medical center for more than 10,000 people in their district. The hospital previously announced plans to reinforce its electrical infrastructure including backup and secondary power generation that included a hydrogen fuel cell to ensure uninterrupted operations. The Kohler system will be used to support the power strategy, helping the hospital to meet its preparedness needs.
