According to a February 21, 2014 article in Energy Trends Insider, the abundance of [ch4] brought about by the fracking revolution is causing some to take a second look at fuel cell powered cars [(fcv)].
“In the mid-1990s, when fuel cell vehicles (FCVs) first appeared on my radar, they seemed like an ideal alternative to the gasoline engines in most passenger cars, offering zero tailpipe emissions and very low lifecycle, or well-to-wheels emissions of all types. Onboard hydrogen (H2) storage ... enabled higher energy density than then-current batteries, giving an FCV ... greater potential range than a comparable electric vehicle (EV) ... [fcv] Cost and technology readiness were the biggest barriers, along with non-existent retail H2 infrastructure.”
Most industrial [h2] is generated by chemically reforming natural gas [(ch4)]. In the early part of the current century, this looked to be economically problematic due to high [ch4] prices. But thanks to the fracking boom, an abundance of [ch4] has been discovered and is being exploited. This has caused prices of the product to plunge, keeping down electricity prices in countries like the United States that allow fracking. Since the price of oil and hence products like gasoline that is refined from oil remains high, [ch4] is suddenly very competitive with regular gasoline.
