Hydrogen combustion is a process where hydrogen reacts with an oxidizing agent to release thermal energy. It requires energy input to initiate the reaction and produces water vapor and heat. Hydrogen has potential as a clean and renewable energy source, but its efficiency is limited. Hydrogen-based fuel cells are being developed for various applications. The Hindenburg disaster is a famous example of hydrogen combustion.
Hydrogen combustion is the process by which hydrogen reacts with an oxidizing agent and burns. The combustion of hydrogen is exothermic combustion, meaning that it releases thermal energy. Endothermic processes, on the other hand, absorb energy. Hydrogen burns according to the chemical formula 2H2 + O2 → 2H2O, which means it reacts with oxygen. Although not shown in the chemical equation, energy input is required to initiate the reaction, which releases a significant amount of energy when completed.
Combustion reactions are more often simply referred to as combustion. There are two essential parts to combustion reactions, including hydrogen combustion: a fuel and an oxidizing agent. With the addition of heat, hydrogen reacts with oxygen to release heat and light energy. The end products of the reaction include water vapor and heat. The heat input is necessary to overcome the attractive forces between atoms and molecules; the energy released comes from the energy that has been stored in the chemical bonds that are broken during the reaction.
Hydrogen combustion has shown some potential to power automobiles and generate energy to meet other human needs. However, due to the required energy input and relatively low energy output, it is difficult to use it efficiently. Fossil fuels are most commonly used for fuel and energy, but the supply of such fuels is very limited and their combustion releases harmful gases into the atmosphere. Hydrogen, on the other hand, is an extremely abundant resource that only produces water vapor when burned. Therefore, energy researches are making significant progress in the development of hydrogen-based fuel cells; some have already been used in automobiles to varying degrees of effectiveness.
While still a relatively new area of study, there are several types of vehicles that have been made to use hydrogen combustion due to its cleanness and renewable nature. Large amounts of hydrogen are actually used to launch space shuttles into space. Smaller vehicles, such as boats and motorcycles, have also been made to use hydrogen combustion.
A famous example of hydrogen burning is the Hindenburg explosion. The Hindenburg was an airship held aloft by enormous quantities of hydrogen. Something aboard the airship triggered an explosion that ignited the hydrogen, causing the massive airship to explode violently, killing 35 people. Many different theories have been advanced to explain the sudden explosion, but the true cause has never been conclusively determined.
