To mitigate diesel generators emissions, Kohler can seize a significant opportunity by transitioning from diesel to renewable fuel sources. One promising alternative that stands out is hydrotreated vegetable oil (HVO), which offers a compelling solution with its lower greenhouse gas (GHG) emissions profile compared to traditional petroleum-derived diesel.

The production of HVO involves either hydrogenation, which adds hydrogen molecules to vegetable oil, or hydrocracking, which employs hydrogen to break down large molecules into smaller ones. Referred to as green diesel or renewable diesel, utilizing HVO instead of conventional diesel can substantially reduce net CO2 emissions by an impressive 90%.

With the growing interest in sustainable energy solutions, it becomes crucial to explore further advancements in generator emissions reduction. By embracing renewable alternatives like HVO, we not only mitigate the environmental impact but also contribute to an energy landscape characterized by cleaner and more sustainable practices. The transition from diesel to HVO offers a transformative approach, providing a reliable and efficient source of backup power while considerably lessening carbon footprints.

Furthermore, the adoption of HVO in generator systems benefits from an already established and easily adaptable infrastructure. Leveraging the existing fuel supply network for conventional diesel, the integration of HVO into generator operations becomes a seamless transition, offering a well-supported and reliable solution for critical applications. The compatibility of HVO with the current infrastructure eliminates the need for extensive modifications or costly investments, making it an attractive and practical choice for minimizing emissions while ensuring uninterrupted power supply in emergency situations.

HVO’s remarkable similarity in grade and quality to conventional diesel offers immense advantages as it can seamlessly integrate into existing engine and fuel system infrastructures without requiring costly modifications or replacements. KOHLER’s extensive research and proven track record demonstrate that their KD engines function flawlessly with the utilization of HVO.

Not only is HVO compatible with the regular blend of petroleum-derived diesel fuels, but it can also be blended with diesel without any complications. Storing and handling HVO is effortless, and it can maintain its integrity for extended periods without significant degradation. Furthermore, the response time of generators remains commendably quick when powered by HVO, yielding comparable performance to that achieved with traditional diesel, thus ensuring prompt and reliable operation when urgently required.

Let's delve deeper into the exceptional CO2 emission reduction capabilities of HVO.

Consider a typical 1000-kilowatt diesel generators that operates for approximately 100 hours each year on fossil diesel; this translates to an emission footprint equivalent to approximately 16 average cars annually. However, when the same calculation is applied to HVO, the outcome reveals a remarkably reduced carbon impact of less than two cars per year. Such impressive figures underscore the substantial environmental benefits provided by HVO in terms of CO2 emissions reduction. Recognizing the potential of such renewable fuels in creating a more sustainable future, Kohler remains committed to further exploring and developing solutions with other clean fuels.

Beyond its impressive reduction of CO2 emissions, the use of HVO in generators delivers additional environmental advantages. Compared to conventional diesel, HVO combustion produces significantly lower levels of harmful pollutants such as nitrogen oxides (NOx) and particulate matter (PM). This reduction in emissions is not only beneficial for the immediate surroundings but also contributes to overall air quality improvement and public health.

Optimizing Power diesel generators maintenance schedules

Finding a balance between ensuring generator readiness and minimizing emissions is crucial for optimizing maintenance schedules. Diesel generators designated for emergency standby power typically spend a significant portion of their lives in idleness, waiting for potential outages. However, to maintain peak performance, regular maintenance is essential, which includes periodic running to ensure everything is in proper working order. Traditionally, these maintenance exercises are conducted with a load to mitigate the occurrence of “wet stacking,” a phenomenon where unburned fuel accumulates in the exhaust system, leading to excessive wear and potential damage.

To enhance both the cost-efficiency for customers and our commitment to reducing emissions, Kohler is focused on reducing the frequency and intensity of maintenance runs required each year. By developing innovative approaches, we aim to minimize the necessary hours of operation and decrease the loads required during maintenance exercises.
