No. Blue Gas Marine (BGM) enables existing engines to run on natural gas in addition to gasoline. This is called a hybrid. In fact, the boater can switch between fuels by simply pressing a button installed at the helm.
The same boat can run on different modes: Hybrid (both gasoline and CNG), CNG Only, and gasoline only. The BGM system does not require gasoline and the engines can start on CNG or gasoline
Yes, in a positive way! Natural gas will combust at a lower temperature than in a gasoline engine, meaning your engines run much cooler on CNG than on gasoline. The combustion of CNG produces zero smoke and that keeps your engine parts working without the associated carbon buildup caused by gasoline. These clean properties of CNG extend the life of your engines. In addition, the BGM fuel system (fuel tank, fuel lines, engine components, engine computer, and even the injectors) is completely independent from the gasoline system, adding another degree of safety to your boating. If you get bad gasoline or a gasoline component malfunctions, simply crank the engines on CNG and come home safely without expensive towing bills.
Gasoline is a liquid commonly measured in gallons, but natural gas is not a liquid so it cannot be measured in gallons in its compressed form. To simplify the use of natural gas as a fuel that commonly replaces gasoline, the US federal government created a unit of measurement called the gasoline-gallon-equivalent or GGE for short. All commercial CNG pumps in the US are therefore required to list the price of natural gas in GGEs and measure it that way when you fill-up your boat. This simplicity allows you to compare the price of natural gas directly to the price of the gasoline without any complicated calculations. If you fill-up from home, you generally pay $1 for a GGE of natural gas compared to $4/gallon of non-ethanol gasoline.
CNG is 130 Octane. This means that it can release energy during a longer time than gasoline. The BGM system takes advantage of the higher octane so there is no significant performance difference between the two fuels. In fact, our tests show a fuel efficiency increase of up to 60% while running on CNG. Additionally, CNG is 33% lighter than gasoline for the equivalent energy. All of this means that your boat will go much farther on an equivalent measure of CNG than on gasoline.
BGM’s fuel system consists of six major modules: engine components, helm controls, fuel receiving panel, fuel tank, pressure reduction module, fuel lines and command cables. These are assembled in our factory specifically for your boat and engine combination. The tank size and mounting location determines almost half the cost of the system. Since there are so many combinations of these factors pricing will vary, but start at $4,000 for a smaller boat. Ask us for a quick estimate that is specific to Sales@BlueGasMarine.com
Blue Gas Marine sells, installs and maintains its fuel systems through qualified and authorized dealers. All BGM dealers’ primary businesses are Marine Service Centers that have the facilities, tools and experience received from our training to provide high quality installations of our plug-n-play CNG fuel systems. Our network of BGM dealers are also certified repair centers for the engines on which the fuel system is installed.
BGM natural gas fuel systems provides a one year warranty for an engine that is out of warranty. BGM matches the engine warranty for an engine that is new or is still covered by the original manufacturer’s warranty.
Compressed Natural Gas is a fuel in a gaseous form that requires a tank to hold it and special valves to dispense it. Your gasoline tank was made to hold a liquid fuel and not a gas, so that is why we add a CNG tank to your boat in addition to your existing gasoline tank for hybrid boats. Customers that only want to operate on natural gas can request that the gasoline tank be removed to provide maximum CNG capacity, although the hybrid configuration provides the most flexibility. CNG tanks are at a pressure of 3600 PSI when full. This pressure will go to almost zero as the engines consume the fuel. Gasoline tanks vent fumes and may potentially spill into the water during fueling.
CNG tanks are self-contained and do not vent or spill any fuel. Additionally CNG tanks may be mounted either horizontally or vertically, providing more flexibility for installation.
Due to the demand for CNG for both personal and fleet usage for businesses there are many options available for CNG. Blue Gas Marine, Inc. has multiple fueling options including:
