In fact, natural gas has a higher ignition point that gasoline which means it takes a higher temperature – approximately 1,200 degrees – to ignite natural gas whereas gasoline can ignite at approximately 600 degrees. If natural gas is so safe, why has it taken so long for it to become an automotive fuel? Humans, by nature, are resistant to change. Although gasoline has a lower ignition point, pools on the ground and is held in thinner tanks than natural gas, it is a known fuel to all of us; it has been the primary automotive fuel since the internal engine was invented, so we perceive it to be safe. In the same vein, natural gas is a known fuel for heating our homes. Can you imagine if someone suggested pumping gasoline through our homes to fuel our furnaces, clothes dryers and kitchen stoves!
