“…Injection needs high pressure, which further limits the storage options. Hydrogen could be stored in cryogenic tanks in the liquid state and injection pressure are generated onboard, or compressed hydrogen is stored, which limits the tank capacity and onboard compression would negate the efficiency benefits of DI (Peschka 1998).…”

Hydrogen has the potential to be the sustainable fuel of the future, decrease the global dependence on fossil fuel resources, and lower the pollutant emissions from the transportation industry. In this study, recent development in hydrogen-based transportation engines is reviewed to scrutinize the feasibility of using hydrogen as a major fuel of future. Using hydrogen in internal combustion engines achieves only 20-25% efficiency and low power output compared to fossil-fueled internal combustion engines. Although hydrogen-based internal combustion engines have recently received considerable interests, several practical barriers have prevented the fast development of this technology. Hence, at the current stage, using hydrogen as an additive to hydrocarbon fuel systems have been taken into consideration to produce higher performance than hydrogen-only internal combustion engines. Using the dual-fuel strategy can increase the combustion stability and thermal efficiency while decreasing the CO and unburned hydrocarbons emissions, and fuel consumption. Alternatively, hydrogen can be used in fuel cells for vehicular applications with several automotive manufacturers producing fuel cell vehicles currently. Fuel cells can achieve efficiencies of up to 60%, while the rest is lost as heat. Strategies that have been investigated to increase the efficiency, performance, and lifespan of fuel cells are capillary pumping systems, a chemisorption chiller, nanofluids and supercapacitors. All such strategies improved the fuel cells in one or more ways. Safety, hydrogen delivery, onboard storage, and the capital and operating costs of hydrogen powered vehicles are analyzed to approach to clean transportation utopia.

In the present paper, the performance and emission characteristics of a conventional four cylinder spark ignition (SI) engine operated on hydrogen and gasoline are investigated experimentally. The compressed hydrogen at 20 MPa has been introduced to the engine adopted to operate on gaseous hydrogen by external mixing. Two regulators have been used to drop the pressure first to 300 kPa, then to atmospheric pressure. The variations of torque, power, brake thermal efficiency, brake mean effective pressure, exhaust gas temperature, and emissions of NO x , CO, CO 2 , HC, and O 2 versus engine speed are compared for a carbureted SI engine operating on gasoline and hydrogen. Energy analysis also has studied for comparison purpose. The test results have been demonstrated that power loss occurs at low speed hydrogen operation whereas high speed characteristics compete well with gasoline operation. Fast burning characteristics of hydrogen have permitted high speed engine operation. Less heat loss has occurred for hydrogen than gasoline. NO x emission of hydrogen fuelled engine is about 10 times lower than gasoline fuelled engine. Finally, both first and second law efficiencies have improved with hydrogen fuelled engine compared to gasoline engine. It has been proved that hydrogen is a very good candidate as an engine fuel. The obtained data are also very useful for operational changes needed to optimize the hydrogen fueled SI engine design. ᭧
