Unless the round trip efficiency of synthesized methane (synthesis, transportation and re-capture) is better than solar/hydro/nuke electricity it doesn't make sense build our own hydrocarbons. There are also the cumulative health effects of burning methane in your house and that it is serious greenhouse gas.
Its a battery. It makes more sense than electricity because its extremely energy dense, can be transported long distances far more efficiently than electricity, and can be stored indefinitely in low-tech gas tanks instead of electrical batteries
Methane has to be compressed for both transportation in pipes and storage in tanks, a very energy expensive process. Or it can be chilled down and condensed to a liquid for bulk transportation in ships, also a very energy expensive process. Every single joint and valve in the distribution network has the potential to leak, and many of them do, the same goes for storage tanks. Also pressure regulators (like the one on the side of your house) have to vent to bring down the pressure when the ~~network~~ house pressure is too high.
Natural gas distribution networks are extremely leaky.
No. They have to vent if your household pressure is too high. If, for example, cold gas was admitted into your lines, and that gas heated up, the pressure in your lines would increase. The regulator can't push that gas back into the high pressure main, so the regulator would have to bleed off the excess pressure.
Derp, that IS right, will correct.
