The Deal with Hydrogen

Hydrogen is the most common element on the planet. Alone this molecule makes up 75% of the worlds mass. From our bodies to water and even plants, hydrogen is nature’s most important building block. If you are unfamiliar with hydrogen then let’s take a look at how the simplest element in the world can serve to revolutionize the way we see energy.

The hydrogen atom has the lowest atomic mass of all other elements. This makes it the lightest element in the world. Despite its mass, it also has a great amount of energy. The hydrogen atom consists of a positively charged proton and negatively charged electron that cancel each other out. This makes hydrogen electrically neutral but the true secrets of hydrogen can be uncovered chemically. The single electrons surrounding the nuclei are highly reactive; this is why they bond into pairs creating a molecule called H2, hydrogen as we know it.

Here at Orobys we develop ways to unlock the power of hydrogen in order to provide sustainable and environmentally safe internal combustion engine applications. Using gaseous hydrogen as a main source of fuel in an engine and improving fuel efficiency with breakthrough technology has been the key to our success. When combusted hydrogen’s only byproduct is water vapor. When ignited in engines, hydrogen produces 2.5 times the energy of hydrocarbons like gasoline or diesel fuel. Consequently the combustion of hydrogen subsides very quickly. It produces more power but dies out quickly. Creating a reliable, yet well balanced engine is the focus of our development, using the strengths and weaknesses of different engines in order to maximize power and efficiency.

Hydrogen, A Bigger Bang for the buck

Making an internal combustion engine greener, more powerful, safer and useful is a complex balancing act. A hydrogen internal combustion engine runs much like a gasoline powered engine. The engine and its components remain the same but the fuels and the ways in which they react is much different. First and foremost we innovate around hydrogen fuel delivery, taking advantage of a better combustion rate, higher flame speeds and low ignition energy. Hydrogen reacts in peculiar ways when inside an engine, focusing on its strengths and mitigating its weaknesses allows us to produce a system that is capable and efficient.

Hydrogen within an engine produces high diffusivity and low density. In an engine this means hydrogen is easier to mix with air when inside the chamber. Its density allows the gas to disperse rapidly inside the engine, making it easy to disperse fuel. When the right conditions are set, hydrogen also combusts with a higher flame speed than that of gasoline, this means the fuel is more precise. It also requires less energy to ignite hydrogen; meaning engine cycles are lean on fuel and more economic to run. Hydrogen allows an engine to do more with less and does it in an environmentally safe way.
