Hydrogen is not new, it's been in widespread industrial use for more than 50 years and codes, standards, and design practices have been developed to enable safe use.
All fuels contain energy and can be hazardous if handled improperly. Like other fuels, hydrogen must be used with care in systems designed around its unique properties. Hydrogen fueling stations and Fuel Cell Electric Vehicles (FCEVs) are designed in accordance with established safety standards to ensure their safety.
FCEVs are cleaner and more efficient than traditional combustion-based engines. Hydrogen FCEVs combine hydrogen stored in a cylinder with oxygen from the air to
produce electricity, with water vapor as the by-product.
