A Comprehensive Survey on Hydrogen as a Fuel

Rise in global industrialization with energy demand, the need for fossil fuels are growing with each day. As a result, several countries are seeking for alternate energy sources to meet the rising need for energy. Hydrogen is indeed a high-efficiency alternative energy source with outstanding qualities. In the transportation industry, the advent  of hydrogen-powered automobiles is projected to minimize fuel consumption and pollution through automobiles. Improving internal combustion engines is a straightforward method to go green. Future advancements in engine technology, as well as the use of alternative fuels, can help reduce hazardous emissions. Hydrogen remains indeed a renewable, high-efficiency, and clean energy that has the potential to safeguard engines' future. This paper provides a comprehensive survey on hydrogen by way of a fuel. The most essential avenue for the internal combustion engine to enter a new hydrogen age that can increase its durability and maximum efficiency is the advancement of elevated hydrogen energy production systems. This paper elaborates the potential of hydrogen as future fuel for variety of application as well as an agent to lowering emission from conventional engines.
