What hydrogen releases upon burning depends on its environment and the type of burning it goes through. There are generally two ways hydrogen can burn: It can be used in nuclear fusion, in powerful reactions such as the ones that cause stars to burn, or it can combust on earth with the help of the oxygen-rich atmosphere.


This process can be repeated in an ongoing cycle, as long as there is a constant input of electricity into the system. However, it takes more electricity to split the water into its component parts than could be produced by burning the hydrogen.


Burning hydrogen in general will produce heat, steam, CO2, trace elements and an explosion if in a confined area. As well, when asking this question, one must consider what by products are produced to create or collect hydrogen, as this is a package deal.


hydrogen burn very hot flame but invisible to the nake eye… to be sure it is burning, just put a small piece of combustible close and it will burn very quickly… for hydrogen, you have 2 kinds of burning: the control one will a continue flame and the explosive one that is very quick to go away..


Hydrogen fuel is a zero-emission fuel when burned with oxygen. It can be used in electrochemical cells or internal combustion engines to power vehicles or electric devices. It has begun to be used in commercial fuel cell vehicles such as passenger cars, and has been used in fuel cell buses for many years. It is also used as a fuel for the propulsion of spacecraft.


Hydrogen (H2) is the lightest, most abundant element in the universe, yet it’s also one of the most flammable. Hydrogen is quick to burn in the presence of oxygen (O2) and can be very explosive. Used as the primary fuel for combustion when launching space shuttles, this is seriously powerful stuff.


Hydrogen is often produced using natural gas, which involves the removal of hydrogen from hydrocarbons at very high temperatures, with about 95% of hydrogen production coming from steam reforming around year 2000. Commercial bulk hydrogen is usually produced by the steam reforming of natural gas.


Demonstration and Class Practical. Test-tubes containing three different proportions of hydrogen and air are prepared and the gas mixtures ignited. The loudness of explosions (‘pops’) is noted and related, at least in part, to the amount of energy produced when the hydrogen is burnt. The mixture producing the loudest ‘pop’ is used to estimate the ratio in which hydrogen and oxygen combine.


Combustion, more commonly called "burning," is a chemical reaction between a substance and oxygen. When hydrogen burns, it reacts with oxygen according to the following chemical equation: 2H2(g ...


Not all the energy released can be utilised; when hydrogen burns, the water produced is as steam, and this takes energy from the burning fuel. This energy lost is known as the enthalpy of evaporation, and is 2442kJ/kg (of water produced).
