The most exciting technology that's being developed is the natural gas powered fuel cell, which uses a chemical reaction to generate electricity from methane, no fuel combustion or heat necessary.
The result is cleaner, more dependable electricity production, especially when you start using recycled natural gas: Landfills are full of organic matter, which naturally produces methane as it decays. The idea is to dig "wells" in the waste piles, releasing and gathering methane – a much more palatable and environmentally-friendly choice than natural gas hydrofracking.
Innovators in the natural gas industry are working on the concept of "distributed generation" – giving individuals the ability to produce their own electricity, at home. This could be done off-grid, a good choice for homes in secluded or rural areas, or by connecting to the same gas lines that power our stoves.
This is a budding technology, but at least one example has already hit the market. The BlueGen small-scale generator is the size of a washing machine that produces more than enough electricity for the average home and even heats water to boot.
As this sort of technology advances, the uses of natural gas will grow exponentially, creating a possible future in which it keeps us on the move and powered up as well as warm and well-fed.
