This ruling uses miles per gallon gasoline equivalent for all fuel and advanced technology vehicles available in the U.S. market including plug-in hybrids, electric vehicles, flexible-fuel vehicles, hydrogen fuel cell vehicle, natural gas vehicles, diesel-powered vehicles, and gasoline-powered vehicles.
There are far fewer Hydrogen filling stations than gasoline fuel stations, which in the US alone numbered 168,000 in 2004. [55] Replacing the US gasoline infrastructure with hydrogen fuel infrastructure is estimated to cost a half trillion U.S. dollars. [56] A hydrogen fueling station costs between $1 million and $4 million to build. [57]
The Hydrogen Expedition is currently working to create a hydrogen fuel cell-powered ship and using it to circumnavigate the globe, as a way to demonstrate the capability of hydrogen fuel cells. [134] In August 2021 the UK Government claimed it was the first to have a Hydrogen Strategy and produced a document. [135]
Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of an alternative fuel it takes to equal the energy content of one liquid gallon of gasoline. GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel, namely gasoline.
These hydrogen engines burn fuel in the same manner that gasoline engines do. The theoretical maximum power output from a hydrogen engine depends on the air/fuel ratio and fuel injection method used. The stoichiometric air/fuel ratio for hydrogen is 34:1. At this air/fuel ratio, hydrogen will displace 29% of the combustion chamber leaving only ...

As of 2020, estimated costs of production are $1–1.80/kg for grey hydrogen and blue hydrogen, [177] and $2.50–6.80 for green hydrogen. [ 177 ] 94 million tonnes of grey hydrogen are produced globally using fossil fuels as of 2022, primarily natural gas, and are therefore a significant source of greenhouse gas emissions.
And the price of gas isn't helping. The average cost of a gallon of gasoline is $3.51 right now, according to AAA. That number is down slightly from last year, but higher than last month's gas prices.
