Hydrogen, the most widespread element in the universe, takes on a range of nuances that reflect the evolution of its production and the future of energy. Although it abounds on our planet, it occurs mainly bonded to other elements and requires energy to be released.
As we enter the world of hydrogen, we are faced with a veritable rainbow of nomenclatures and colors that outline the new energy economy. Let us discover together all the nuances that characterize this world!

Green hydrogen: the real green breakthrough
Green hydrogen, produced through electrolysis powered exclusively by renewable sources such as photovoltaics or wind power, represents the pinnacle of sustainability in hydrogen production.

Blue Hydrogen
Blue hydrogen is a form of hydrogen produced through the process of methane reforming, which involves natural gas as the feedstock. However, unlike conventional hydrogen production from natural gas, in blue hydrogen the production plant is coupled with a system to capture and permanently store the CO2 produced in the process. This process, known as “capturing and storage” or CCS, reduces CO2 emissions, making blue hydrogen a potential transitional solution toward a more sustainable hydrogen economy.

Other Hues of Hydrogen

Yellow Hydrogen: A subcategory of green hydrogen, generated through solar-powered electrolysis
Turquoise Hydrogen: Extracted from methane by pyrolysis: The process involves heating the gas in the absence of oxygen to thermally break chemical bonds to obtain solid hydrogen and carbon
Purple Hydrogen: Similar to green hydrogen, but powered solely by nuclear energy.
White Hydrogen: White geological hydrogen, as it is called by scientists, is formed in various geological settings. The most common process is the serpentinization of rocks in the Earth’s mantle.
Gray Hydrogen: Produced through steam reforming of methane, with all emissions released into the atmosphere.
Brown Hydrogen: The most environmentally damaging, obtained through coal gasification, releasing CO2 and carbon monoxide.

Guided Toward a Sustainable Future.
As we explore the many nuances of hydrogen, we cannot overlook the crucial role of innovative technologies in shaping the future of energy. Companies like ILT Energia, a leader in hydrogen generators, are leading this energy revolution.

Through their research and development, ILT Energia is helping to make sustainable solutions for hydrogen production, such as electrolysis powered by renewable sources, accessible. In a world where the transition to a low-carbon economy is increasingly urgent, the work of companies like ILT Energia takes on a critical importance in shaping a more sustainable future for all.

The hydrogen color classification not only directs investment in the hydrogen economy, but also makes the origin and environmental impact of the H2 carrier clear to the general public.
With a wide range of options, it is essential to move toward solutions that not only meet energy needs but also preserve our planet for future generations.

ILT Energia stands out in the industrial sector for producing hydrogen, oxygen and nitrogen generators and technical gas treatment systems and has always been committed to reducing environmental impact in industrial processes such as braze welding. Today, the company is advancing further in the area of sustainability with an ambitious project to recover hydrogen produced during the testing phase of electrolyzers.

The history of Hydrogen begins with the discovery of Robert Boyle in 1671. Since that time, technological advances around the use of this Gas have followed one another until today, where we see Hydrogen counted among the major players in the energy transition to a more sustainable future.

Right now, the welding industry is coming together for the 2023 edition of Schweissen-Schneiden, the world’s leading trade fair. In this edition 2023 ILT Energia is waiting for you as usual to present the range of hydrogen and oxygen generators and nitrogen generators, created to be perfect machines for welding.

The American Society of Mechanical Engineers (Asme), has chosen Boston as the venue for Turbo Expo 2023, the global event for all turbomachinery professionals. ILT Energia and ILT Tecnogie will both be present to offer an overview of our gas turbine maintenance services and prototyping activities.

ILT Energia was pleased to participate to HYDROGEN EXPO, the exhibition dedicated to the technological sector for the development of the hydrogen supply chain. The Piacenza Expo pavilions hosted three days of discussion and debate on issues of urgency and topicality, which see hydrogen as a key element of the energy transition and decarbonization policy aimed at reducing global pollution.

ILT Energia took part in OroArezzo, the event dedicated to Italian and international goldsmith excellence.
We presented our range of hydrogen and nitrogen generators to companies specializing in gold, silver and jewelry processing. Thank you all for stopping by to visit us at booth 212!

From May 17 to 19, 2023 will be held in the Piacenza Expo spaces the 2nd edition of HYDROGEN EXPO, the innovative Italian exhibition dedicated to the technological sector for the development of the hydrogen supply chain.  We will be happy to host you at stand C114 to tell you all about our on-site hydrogen generators. We look forward to seeing you at booth C114!
