Hydrogen, the most abundant element in the universe, is finally stepping out to take the spotlight. As the world seeks alternatives to fossil fuels, green hydrogen is poised to play a vital role. Standing as a beacon of hope, H2 represents a sustainable solution capable of powering industries and decarbonizing sectors once thought impossible to transform. The story of green hydrogen is one of discovery, innovation, and significant evolution. Emerging as a revolutionary energy solution, green hydrogen holds immense promise in reshaping our energy landscape and driving sustainable progress.
Philip van Hohenheim first recorded the observation of hydrogen somewhere around 1520. While he didn’t recognize it as a new element, Hohenheim initially produced hydrogen gas by mixing strong acids with metals (i.e., iron, zinc, etc.). It wasn’t until 1766, however, that hydrogen was recognized as the distinct element it is. Henry Cavendish was the first to put its properties to paper, dubbing it “inflammable air”. And, in 1783, hydrogen finally received its name by Antoine Lavoisier. Hydrogen, the lightest and most abundant element in the universe, derives its names from the Greek words ‘hydro,’ meaning water, and ‘genes,’ meaning creator or producer, symbolizing its unique ability to form water when it burns.
Nowadays, hydrogen holds a unique position in the periodic table. Its simplicity and abundance have fascinated scientists for centuries. Initially viewed as a scientific curiosity, hydrogen's potential as an energy source began to gain attention in the 20th century. Early methods of hydrogen production primarily relied on processes like steam methane reforming, which laid the groundwork for its industrial applications. However, it wasn’t until hydrogen was explored for various applications, that its sheer versatility was fully evident. In fact, its ability to release energy efficiently made hydrogen an ideal candidate to store and generate energy long before the concept of "green hydrogen" even emerged.
Today, advances in electrolysis are driving hydrogen production into a sustainable future. Interestingly, these advancements can trace their roots to innovative uses like oxygen generation systems for submarines. First introduced over 60 years ago, these systems leveraged Proton Exchange Membrane (PEM) electrolysis to efficiently split water into hydrogen and oxygen in confined spaces. This pioneering application not only showcased the practicality of PEM electrolysis but also laid the foundation for its evolution into a cornerstone technology in renewable hydrogen production today.
