Can locomotives run on natural gas?
That is the ground-breaking question Canadian National Railway is hoping to answer by retrofitting the diesel engines in two 3,000-horsepower Electro-Motive Diesel SD40-2 locomotives to run on natural gas.

These two locomotives will not be fueled solely by natural gas but by a mix of 90 per cent natural gas and 10 per cent diesel fuel for ignition. The natural gas retrofit seems like a logical step for the railway industry as roughly 25 percent of crude and natural gas from shale deposits is currently carried by train. Not to mention all the drilling materials, construction equipment and machinery that are also moved by the railways.
Canadian National is testing the two locomotives along the 298-mile stretch between Edmonton, a natural gas pipeline hub, and Fort McMurray, an oilsands production site.
“CN launched this locomotive test to explore the use of natural gas as a potential alternative to conventional diesel fuel. This reflects CN’s continuing drive to look for ways to improve operating efficiency and advance the company’s sustainability agenda,” said Keith Creel, executive vice-president and chief operating officer.

Switching to natural gas will reduce carbon dioxide emissions by 30 per cent and nitrogen oxide emissions by 70 per cent over a locomotive duty cycle.
Canadian National is also working on a longer-term project to develop an all-new natural gas locomotive engine as well as a specialized tank car to carry the fuel.

Have you ever wondered just how that electricity got to your light bulb or microwave?
The electricity powering your light bulb is produced in a power plant by generators. Energy cannot be created or destroyed just changed from one form to another. Newly generated electricity is then transported over the power grid to your electrical outlet.
The United States has three power grids that keep the lower 48 states powered:
- The Eastern Interconnected System east of the Rocky Mountains
- The Western Interconnected System from the Pacific Ocean to the Rocky Mountains
- Texas Interconnected System
These three separate systems are interconnected and require constant oversight to ensure that all the components are linked together. Since large quantities of electricity cannot be stored effectively or efficiently, electricity must be produced as it is used, this increases the need to watch over the grid. Control centers are utilized to monitor the supply and demand to safeguard against blackouts. To avoid blackouts there must always be a perfect balance between supply and demand.
From the control centers electricity is constantly monitored as it travels from the power plants to high-voltage power lines that transport electricity throughout the three grids. The higher the voltage the more efficiently they transport electricity. In other words the higher the voltage the more electricity will get to the end point. However, there will always be losses as electricity flows through the power grid.
From the high voltage power lines the electricity is “stepped-down” to lower voltage power lines, utility poles and wires before it can be safely used in your home or office.
Do you know how much you are paying for the electricity you use?

The known amount of natural gas in the US has increased over the last 5 years to the point that it now represents over 20% of all the US’s energy reserves (remember some call the US the Saudi Arabia of coal). The natural gas recoverable by the use of hydraulic fracturing (fracking) is a game changer for the US.

There is discussion among business leaders (not politicians) that the conversion to natural gas vehicles and investment in natural gas distribution could reduce oil imports over 60% within 5 years! This is not a political aspiration it’s business.
How has the electric energy industry responded?
Well electricity and natural gas have always been competitors through technology. Natural gas heating applications have been constantly targeted by electric heating. Electric motors have been challenged by natural gas driven engines. Large electric driven air conditioning systems have competed with natural gas driven absorption technology.
So given that natural gas resources (from fracking) has allowed natural gas to truly challenge gasoline as a transportation fuel I am not surprised that an electric option will not be far behind!
Let’s keep competing.
