What is the most common fuel used for microturbines?

Natural gas is the most common fuel used for microturbines due to several key factors. Primarily, natural gas is readily available in most regions and can be delivered through an extensive pipeline network, which makes it a convenient option for many applications. Additionally, natural gas has a high energy content and burns cleaner than many other fossil fuels, producing lower emissions of pollutants such as sulfur dioxide and particulate matter. This makes it an environmentally appealing choice, particularly in areas seeking to reduce their carbon footprint.

Furthermore, microturbines are designed to operate efficiently at the lower combustion pressures associated with natural gas, which can lead to improved overall system efficiency. This capability allows microturbines to generate electricity and heat with high efficiency, maximizing the energy extracted from the fuel.

While other fuel options like propane, diesel, and coal can be used in certain applications, they are generally less favored for microturbine technology. Propane, for instance, is more expensive and less readily available in larger volumes compared to natural gas. Diesel can be used, but it has a higher environmental impact and may result in stricter regulations regarding emissions. Coal, while being a traditional energy source, is not typically suitable for microturbine applications due to efficiency and emissions
