Gasoline is about 87% carbon and 13% hydrogen by weight. Because the previous example proved that 33.4 kilowatt hours of electricity is equivalent (in energy) to one gallon of gasoline (114,000 BTU); this means 33.4 kilowatt hours is also equivalent (in energy) to one kilogram of hydrogen gas. ÷ 50 gallons per drum = 6.66 "barrels of H2" per 1000 gallons of water. Hydrogen produced today is extracted from natural resources like water (via electrolysis), coal and natural gas (via water-gas shift). Then they convert water to hydrogen and oxygen with the electricity. While the Mirai's specs list ~122.4 liters ( ~ 7.47 kg per OP's calculations ), real world fill up is actually 5 kg which is about 67% (5/7.47). The average fuel efficiency of conventional diesel transit buses is approximately 3.87 miles per gallon. The slipperiest molecule might have a 3-4% transportation play in larger form factors (and maybe it will hold onto its forklift market for a while longer), but for cars it makes no sense. It is very clear that Hydrogen is cheaper than Gasoline or Diesel. Renewables Provided 92.3% Of Kenya’s Electricity Generation in 2020! Overall, you can get up to 93 miles per gallon from a hydrogen car versus an average of 35 miles per gallon from a gasoline car. So the carbon in a gallon of gasoline (weighing 6.3 pounds) weighs 5.5 pounds (.87 x 6.3 pounds = 5.5 pounds). Answer (1 of 3): Stats for the space shuttle according to a 2001 NASA fact sheet: NASA bought hydrogen at 98 cents per gallon. How much does a gallon of hydrogen fuel cost? Two hydrogen atoms combine with one oxygen atom to form H2O, or water. The 2008 Honda FCX Clarity boasted 134 horsepower and could get up to 99 miles per hour. Is that right? To make it into fuel for fuel-cell vehicles, the hydrogen must be compressed. He's available for consulting and speaking engagements, and Board positions. The electricity can be produced from many different carbon-free sources of energy such as wind, solar, biomass and geothermal as well as nuclear energy. Found inside â Page 471Producing hydrogen equivalent to total US oil use would require a collector field in the Southwest of some 64 thousand ... ( In contrast , synthetic fuels from coal would release almost twice as much carbon dioxide per unit of energy ... This means its nucleus (center) contains 6 protons and 6 neutrons, adding up to 12. Copyright © 2021 CleanTechnica. Found insidetechnology, hydrogen could be produced from coal with sequestration of the carbon dioxide coproduct at a cost of $6.4 ... this plant-gate cost of hydrogen is equivalent to a gasoline price of $0.92 per gallon, not much higher than the ... • 1 kg of hydrogen has the same energy content as 1 gallon (3.2 kg) of gasoline. It combusts back into water. Hydrogen has an energy density of 39 kWh/kg, which means that 1 kg of hydrogen contains 130 times more energy than 1kg of batteries. Americans may not want to convert their cars to run on hydrogen gas, but know that it can be done using existing technology. Over 70% of the earth’s surface is covered by the oceans of the world—the average ocean depth exceeds two miles. They generate enough electricity to power the . That means 11 MWh will allow a Tesla Model S to drive about 37,000 miles. The newest hydrogen car to go on sale is the Hyundai NEXO - the South Korean manufacturer's technological flagship. Hydrogen The external tank of the shuttle carries about 384,071 gallons (227,800 pounds) of liquid hydrogen, but about 628,540 gal-lons (372,800 pounds) are used in all during shuttle vehicle loading. The amount of hydrogen extracted from a gallon of water can be found very easily using the molecular weight of H 2 0 (water), Hydrogen and Oxygen, along with mass conservation. A barrel of oil equivalent has a LHV of about 35.6 kWh/gal which is very close to the 35.3 kWh/gal LHV figure for a typical gasoline. How this is calculated:1 gallon of gasoline weights 8.66lbs, of which 1.4 lbs is Hydrogen, as gasoline contains 16% Hydrogen and 84% . Found inside â Page 13No one at the White House seemed to realize that, with present technology that requires a fuel cell, the cost of hydrogen energy is much higher than conventional fuels. As of 2007, hydrogen fuel cost the equivalent of $6â 10 a gallon ... Hydrogen can replace all forms of fossil fuels. Found inside â Page 159A Complete Guide to Trading Green in Solar, Wind, Ethanol, Fuel Cell, Carbon Credit Industries, and More Richard W. ... is a comparable cost to U.S. gasoline prices, which are currently near $3 per gallon.25 Hydrogen Delivery Costs As ... NASA bought oxygen at 67 cents per gallon. So very roughly, last month's test firing probably cost taxpayers about $346,500 -- or $647 . Convert 114,000 BTU to equivalent in Kilowatt hours, Convert one gallon of gasoline to the GGE in hydrogen, the internal combustion engine can use hydrogen gas.
