Second thing, look for parafin blocks. May be in your area those are cheap. If so, you can store them for long time and in case of need use as compact fuel source (paraffin is main component in outdoor candles). Sterain would be better (less toxic), but it is more expensive, and not sure about how well it stores in longer term.
