In addition, propane and biodiesel offer many other benefits that can offset this difference. The table below displays the energy content, GGE, and DGE values of conventional and alternative fuels. The values in the table above can help standardize fuel amounts for comparisons. Subscribe to feeds for updates on EIA products including Today in Energy and What's New. The Hydrogen Materials—Advanced Research Consortium (HyMARC) conducts foundational research to understand the interaction of hydrogen with materials in relation to the formation and release of hydrogen from hydrogen storage materials. What do I pay for in a gallon of regular gasoline and diesel fuel? Understanding the energy content of fuels can help inform comparisons of fuel prices and vehicle driving range. Hydrogen can be stored physically as either a gas or a liquid. Propane: 1 gallon = 91,500 BTU 1 cubic foot = 2,500 BTU 1 pound = 21,500 BTU 4.24 lbs = 1 gallon 36.39 cubic feet = 1 gallon: Natural Gas: Three main grades of gasoline are sold at retail gasoline refueling stations: Some companies have different names for these grades of gasoline, such as unleaded, super, or super premium, but they all indicate the octane rating, which reflects the antiknock properties of gasoline. Propane: 1 gallon = 91,500 BTU 1 cubic foot = 2,500 BTU 1 pound = 21,500 BTU 4.24 lbs = 1 gallon 36.39 cubic feet = 1 gallon: Natural Gas: As for hydrogen, these vehicles tend to have larger fuel tanks overall. Energy density is the amount of energy stored in a given system or region of space per unit volume or mass. Gasoline is a fuel made from crude oil and other petroleum liquids. Energy Equivalency of Fuels This calculator allows you to calculate the amount of each fuel necessary to provide the same energy as 1 kg of hydrogen, 1 million cubic feet natural gas, 1 barrel of crude oil, or 1 gallon of other fuels, based on lower heating values. Fuel Energy Content & Conversions: The exact values will vary depending on the quality of the fuel and in some cases the pressure. For instance, all-electric vehicles (EVs) are significantly more efficient than conventional gasoline vehicles. Filling up with a less energy-dense fuel often means that you will not be able to drive as far. Energy content or calorific value is the same as the heat of combustion, and can be … The long-term pathway focuses on both (1) cold or cryo-compressed hydrogen storage, where increased hydrogen density and insulated pressure vessels may allow for DOE targets to be met and (2) materials-based hydrogen storage technologies, including sorbents, chemical hydrogen storage materials, and metal hydrides, with properties having potential to meet DOE hydrogen storage targets. Welcome to the Hydrogen Analysis Resource Center. Energy Content of Selected Fuels Any evaluation of alternate fuels and their contribution to climate change must include consideration of "energy density", a measure of the amount of energy stored in a given volume or mass (weight) of that fuel. Fleets and drivers purchasing a CNG vehicle may have the option to install an additional CNG storage tankonboard the vehicle. Some companies also have detergents and other additives blended into gasoline before delivery to retail outlets. It therefore has units of energy per length cubed or energy per mass. For that reason, the Clean Cities Alternative Fuel Price Report shows prices on an energy-equivalent basis (Table 3 in recent reports).

Maps, tools, and resources related to energy disruptions and infrastructure. Blending terminals are more numerous and widely dispersed than petroleum refineries, and they have equipment for filling tanker trucks that transport finished motor gasoline to retail outlets. The specific energy and energy density of a fuel provide practical measures of the energy content of a fuel in units more commonly used in the storage and handling of these substances (energy per weight and volume). Petroleum refineries and blending facilities produce motor gasoline for sale at retail gasoline fueling stations. Comprehensive data summaries, comparisons, analysis, and projections integrated across all energy sources. 3.61 × 10 6 joules is 1 Kwh and 1 Kwh can run a TV for about 24 hours. The energy content of fuels is one factor that affects driving range. Actual energy content varies, by up to 4%, from season to season and from batch to batch.On average, about 19.5 USgal of gasoline are available from a 42 USgal barrel of crude oil (about 46% by volume), varying due to quality of crude and grade of gasoline. On a volume basis, however, the situation is reversed; liquid hydrogen has a density of 8 MJ/L whereas gasoline has a density of 32 MJ/L, as shown in the figure comparing energy densities of fuels based on lower heating values. On a mass basis, hydrogen has nearly three times the energy content of gasoline—120 MJ/kg for hydrogen versus 44 MJ/kg for gasoline. Uranium fuel, nuclear reactors, generation, spent fuel. U.S. ! Gasoline blendstocks require blending with other liquids to make finished motor gasoline, which meets the basic requirements for fuel that is suitable for use in spark ignition engines. CNG and hydrogen vehicles, on the other hand, often have larger tanks to offset the lower energy densities associated with these fuels. Fuel Energy Content & Conversions: The exact values will vary depending on the quality of the fuel and in some cases the pressure. Petroleum refineries and blending facilities produce motor gasoline for sale at retail gasoline fueling stations. To overcome these challenges FCTO is pursuing two strategic pathways, targeting both near-term and long-term solutions. For example, conventional gasoline has an energy content of 116,090 Btus per gallon, while propane has an energy content of 84,250 Btus per gallon. Energy Source Unit Energy Content (Btu)Electricity: 1 Kilowatt-hour: 3412: Butane: 1 Cubic Foot (cu.ft.) As you can see in the table above, both of these fuels have lower energy densities than their conventional fuel counterparts, which subsequently can result in lower fuel economy and shorter range per tank. 1 joule is equal to 2.7777777777778E-7 kWh, or 7.5895567698846E-9 gallon [U.S.] of automotive gasoline. GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel—gasoline. What are the projections for U.S. gasoline and diesel fuel prices. Hydrogen can also be stored on the surfaces of solids (by adsorption) or within solids (by absorption). Energy & Financial Markets: What Drives Crude Oil Prices? The Heat of Combustion of a product measures the energy released when that substance is burned in air, this information is often presented in units of .. Therefore, E85 energy content calculated as [(.70) x (E100 energy content)] + [(.30) x (gasoline energy content)]. Reports requested by congress or otherwise deemed important. Come test out some of the products still in development and let us know what you think! To calculate GGE and DGE, the energy content of one gallon of gasoline or diesel is divided by the energy content of the comparison fuel. For instance, if one gallon of E85 is $2.04, you would multiply by 1.32 (see table above ) to find that this price equates to $2.69 per GGE after adjusting for energy content. Note that rounding errors may occur, so always check the results. Energy-Related Carbon Dioxide Emissions, Energy-Related Carbon Dioxide Emissions at the State Level, 2005-2016, Energy-Related Carbon Dioxide Emissions at the State Level, through 2017, Domestic Uranium Production Report – Quarterly, Monthly Crude Oil and Natural Gas Production ›, Midwest and Rocky Mountain Transportation Fuels Markets, East Coast and Gulf Coast Transportation Fuels Markets. This is less of an issue for stationary applications, where the footprint of compressed gas tanks may be less critical. EIA's free and open data available as API, Excel add-in, bulk files, and widgets. This is one reason why EVs have such significant fuel economy advantages over conventional vehicles, even when you are comparing the fuels on an energy-equivalent basis. Gasoline has an energy density of about 45 megajoules per kilogram (MJ/kg). H2 Tools is intended for public use. FCTO conducts research and development activities to advance hydrogen storage systems technology and develop novel hydrogen storage materials. That means a gallon of gas contains the energy density to power your television for 36 straight days - in a comparatively tiny package. Regional energy information including dashboards, maps, data, and analyses. $10/kWh ($333/kg stored hydrogen capacity).
