Diesel is a popular fuel for generators because it is widely available, easy to store, and has a high energy density. However, diesel fuel can be expensive, and generators that run on diesel tend to consume more fuel than those that run on other types of fuel. Additionally, diesel generators require regular maintenance to keep them running smoothly.
Natural gas is another popular fuel for generators. It is less expensive than diesel, and generators that run on natural gas tend to be more fuel-efficient. However, natural gas generators require a steady supply of gas, which can be difficult to obtain in some areas. Natural gas generators also require special equipment to convert the gas into energy.
Propane is a clean-burning fuel that is easy to store and transport. Propane generators are usually more fuel-efficient than diesel generators, and propane is less expensive than diesel. However, propane generators can be more expensive to purchase initially, and they require regular maintenance to keep them running smoothly.
CNG (compressed natural gas) is similar to natural gas but is stored at a higher pressure. CNG generators are more fuel-efficient than diesel generators and produce fewer emissions. However, CNG is not as widely available as natural gas, and CNG generators can be more expensive to purchase initially.
Hydrogen is a clean-burning fuel that produces no emissions. Hydrogen generators are highly efficient and require little maintenance. However, hydrogen is not widely available, and hydrogen generators can be expensive to purchase.
In terms of fuel cost, natural gas and propane are generally less expensive than diesel and gasoline. However, the fuel consumption of your generator will depend on its size and load. Larger generators will consume more fuel than smaller generators, and generators that are run at full load will consume more fuel than those that are run at partial load.
When it comes to fuel storage, diesel and gasoline are the easiest fuels to store. They can be stored in large tanks and are readily available. Propane and natural gas require special tanks and equipment for storage, and CNG and hydrogen require even more specialized storage solutions.
