Even if it does not, you could use it as a nice chemical battery. Say you split some water ice using energy from you nuclear reactor (or possibly even a turbine in your methanoelectric dam!) and store the pressurized oxygen. Then you can use the stored oxygen with methane from the atmosphere to provide a lot of energy where needed, possibly far away from your main nuclear reactor, dam on a liquid methane river or other non-portable energy sources.
