Alternative fuels

Ethanol

UL offers a new certification path for fuel dispensers for mid-level ethanol blends up to E25. With the new certification path, manufacturers of dispensers, assemblies and components now have three certification options to choose from to balance market needs and provide maximum flexibility as advances are made in the fuel industry. Learn more.

Fuel cells

Fuel cell technology has been developing for several decades and practical commercial products are obtainable. A typical fuel cell is an electrochemical device that converts pure hydrogen (or a hydrogen rich gas derived from hydrocarbons such as natural gas, gasoline or methanol) into electrical energy and heat.  Learn more.

Hydrogen products

Most fuel cell power sources require pure hydrogen or hydrogen rich gases to operate efficiently. Due to this hydrogen need, new industries have emerged to provide hydrogen generation, storage and dispensing products. Applications resulting from this industry include the refueling of vehicles with on-site hydrogen generators and storage tanks as well as replacement fuel containers for smaller scale consumer products, for example, electronic products such as cell phones and portable computers. Specific hydrogen-related products within the industry include the individual containers, hoses and safety devices associated with storage and dispensing equipment; solar or photosynthesis devices to generate hydrogen directly; and conversion devices that obtain hydrogen from natural gas, gasoline, methanol and other hydrocarbons.
