![]() If a combination of refueling speed and range is valuable to you and you have access to hydrogen refueling, a fuel cell vehicle could offer the best of all worlds.The Hyperion XP-1's main purpose is to generate interest in hydrogen power, the company's CEO said. On the other hand, both the Tesla and the Volkswagen take much longer to charge and deliver less driving range than the Mirai and the Nexo, both of which can be refueled in less than five minutes. For instance, the electric Tesla Model S is rated at 119 city MPGe and 112 highway MPGe, while the Volkswagen ID.4 is rated at 104 city MPGe and 89 highway MPGe. Those numbers compare very favorably to gasoline vehicles of the same size, most of which rate in the 20s and 30s, but they are less efficient than similarly sized electric cars. Once that amount of energy is determined, the vehicle’s consumption of energy per distance – gasoline, electric, hydrogen, or a mix – can be used to calculate its MPGe.įor reference, the most efficient version of the Toyota Mirai is rated at 76 MPGe in the city and 71 MPGe on the highway, while the Hyundai Nexo carries ratings of 65 MPGe city and 58 MPGe on the highway, due to its taller SUV body. How is a vehicle’s MPGe determined? The EPA uses a formula to calculate the precise amount of electric energy that’s equal to the energy in one gallon of gasoline. Its purpose is to relate the amount of energy used by alternative-fuel vehicles to that of their traditional gas-powered counterparts. MPGe is an energy efficiency metric that was created by the EPA when the first plug-in hybrid and electric vehicle models were being introduced to the market. The EPA also provides MPGe (miles per gallon equivalent) ratings to help you understand the relative efficiency of hydrogen fuel cell cars. The Toyota Mirai sedan carries a range estimate of 402 miles. The Hyundai Nexo SUV carries an EPA range estimate of 380 miles in its most efficient (and least expensive) form. To help potential buyers compare their options, the EPA provides range estimates for fuel cell electric vehicles - in the same way that they provide estimates for battery electric vehicles. ![]() Because they produce their power on-board from stored hydrogen, the battery can be much smaller and lighter – improving performance, efficiency, and ultimately range. That doesn’t mean that fuel cell vehicles have poor range. Hydrogen fuel cell vehicles are relatively lighter and less complex than gasoline vehicles and because they don’t rely on a huge battery to derive decent driving range, they are relatively lighter than battery-powered electric vehicles. A chemical reaction produces electric current and water, which is the car’s only emission. From the pressurized fuel tank, the gas flows to a fuel cell system, which combines the hydrogen with oxygen from the air. Instead, you simply fill a tank with compressed hydrogen gas, which takes about five minutes. Fuel cells combine hydrogen and oxygen in the presence of an electrolyte to produce electric current – like an on-board power generating station!Ī hydrogen fuel-cell vehicle is an electric vehicle, just without a plug. This makes hydrogen fuel cell cars sound like a new thing, but fuel cells are a technology that pre-dates the automobile. The first mass-production fuel cell cars for America, the Hyundai Nexo and Toyota Mirai, will be delivered in 2022.
