Renewable fuels battle it out: Methanol vs. Sodium Hydride

Methanol could facilitate the introduction of fuel cell vehicles, since the refuelling infrastructure would be almost identical, as would the cost per gallon at the pumps. However methanol is not truely a renewable fuel. It consumes natural gas in its production, and burns away completely when used in a car. Although it gets better fuel efficiency than a gasoline car it still produces greenhouse gases, smog forming gases, and depletes a non-renewable resource.

Sodium hydride may be a truely renewable fuel. All it does is store hydrogen, which can be obtained by solar electrolysis of water, and stores 1.6-times more hydrogen per unit volume than methanol. It requires heat to produce which makes it more amenable to solar, wind, OTEC & biomass powerplants, whereas methanol requires a carbon-based fuel to produce such as methane or naptha without which methanol could not be produced at all. Sodium hydride stores more hydrogen per unit volume than liquid hydrogen, methanol or any other method. It is simply immersed in water and releases pure hydrogen to an automotive fuel cell. The spent fuel is identical to laundry detergent, and is reprocessed back into fuel to be used again. In this way it requires more infrastructure than methanol, ie. a recycling & re-use supply line. But it is my choice to compete with methanol for a renewable automotive fuel infrastructure.
