Whatever happened to fuel switching between natural gas and diesel? The switch from diesel to natural gas is one of the biggest types of fuel switching in transport. You see this with all the buses now running natural gas instead of diesel. Other companies with fleets of cars and trucks are making the switch too. So, peak oil or not, you know something is not right when diesel fuel is hitting record highs across Europe and Gasoline is edging toward $4.00 a gallon in the US while natural gas prices are at 10-year lows.
Here’s what the EIA says about fuel switching in the manufacturing sector:
A fuel may be completely or partly nonswitchable. In the case of it being completely nonswitchable, it often means that the configuration of the plant’s equipment would not allow another fuel to be used in place of the one currently being consumed. Even when an establishment has the ability to switch a portion of its consumption from one fuel to another, it could have a certain amount for which it cannot substitute. The term used to describe both types of situations is, “nonswitchable minimum requirement.” For example, a plant may use natural gas in both a boiler and specialty oven used to dry paint. In the boiler, all fuels used may be completely interchangeable. However, in the oven, using something other than natural gas may alter the pigment of the paint. In that case, the natural gas would be nonswitchable. Other reasons a fuel may be partly nonswitchable are the practical considerations such as in-place take-or-pay contracts with a supplier or environmental restrictions that limit the amount the establishment can consume during a specified time.
They then provide a chart of switchability based on decade old data. I bet the numbers are higher for natural gas today. In any event, this is something I have been watching in awe and I suspect portfolio preference-based speculation is a large part of why there is such a dichotomy. Does anyone have more information? Also, why are companies drilling shale oil wells when the spot market is cratering?
