(n)ĬNG is domestically produced from natural gas and renewable biogas. E85 reduces lifecycle petroleum use by 70%, and E10 reduces petroleum use by 6.3%. (l)Įlectricity is produced domestically from a wide range of sources, including through coal-fired power plants and renewable sources, making it a versatile fuel.īiodiesel is domestically produced, renewable, and reduces petroleum use 95% throughout its lifecycle. energy needs and 70% of petroleum consumption. Transportation accounts for approximately 30% of total U.S. Can cause serious damage to organs in the body if a person swallows it, breathes it in, or gets it on their skin. Special lubricants must be used as directed by the supplier as well as M85-compatible replacement parts. High-pressure tanks require periodic inspection and certification. When hydrogen is used in fuel cell applications, maintenance should be very minimal. The vehicle should be operated on a schedule to maintain a lower pressure in the tank. LNG is stored in cryogenic tanks with a specific hold time before the pressure build is relieved. Practices are very similar, if not identical, to those for conventionally fueled operations. For more maintenance information, see the Biodiesel Handling and Use Guidelines-Fifth Edition. Lubricity is improved over that of conventional low sulfur diesel fuel. Pressurized liquid (heavier than air as a gas)Ĭompressed gas (lighter than air) or liquid (1 kg) of H 2 has the same energy as 1 GGE.ġ gallon of methanol contains 50% of the energy as 1 GGE.Ĭryogenic liquid (lighter than air as a gas) (a)ġ gallon of propane has 73% of the energy in 1 GGE due to the lower energy density of propane.Ģ.2 lbs. of LNG has the same energy as 1 GGE, and 6.06 lb. ĥ.66 lb., or 123.57 ft 3, of CNG has the same energy as 1 GGE, and 6.37 lb., or 139.30 ft 3, of CNG has the same energy as 1 DGE.
