“The threat of climate change has resulted in urgent demand for more sustainable mission-critical power technologies,” according to a new white paper from Kohler. While the engine optimizations that resulted from the US EPA Tier 4 and European Stage V requirements have gone a long way to reducing harmful emissions, Kohler says generator manufacturers are taking other steps to further improve the environmental performance of their products.

Kohler cites new maintenance techniques as one area in which the generator industry has progressed. They note that mission-critical generators are “often used for less than 12 hours per year and at low loads since most of the runtime is for monthly exercising.” This presents a challenge because it leads to wet stacking, or a buildup of unburnt fuel in the exhaust system. Kohler outlines how technological advancements have created more efficient and environmentally friendly maintenance techniques that reduce emissions and improve engine performance.

“There is a genuine desire for more sustainable operations, from OEMs and end-users alike, and generator manufacturers have invested heavily in pursuit of more environmentally friendly technologies.” – Kohler, “Delivering More Sustainable Mission-Critical Generators – Now and in the Future

Renewable fuels are another area in which generator manufacturers are investing heavily, according to the paper. The author explains how fuels like Hydrotreated Vegetable Oil (HVO) provide “a simple and efficient renewable alternative to fossil diesel that can be used right now.”

Finally, Kohler outlines how they and other generator manufactures are “evaluating the potential of revolutionary technologies for mission-critical power, such as batteries and fuel cells.” The paper explores the benefits, challenges, and practicality of each.
