Hydrogen as a key factor for the global energy supply
Hydrogen is more than just a chemical element – it is an indispensable building block for a sustainable energy future. Its flexible, environmentally friendly nature and potential for storing renewable energy make it a key factor in the energy transition. However, in order to fully exploit this potential, considerable investment is needed in infrastructure, the further development of technologies and the reduction of production costs. Thanks to continuous improvements in efficiency, hydrogen will play an increasingly important role in the global energy supply in the coming years.
In the pursuit of innovation and environmental friendliness, Hexagon Purus is taking a leading role with a wide range of solutions for sustainable mobility and hydrogen storage, setting new standards for individual requirements in terms of storage volume, pressure level, space requirements and vehicle integration in various sectors.
Flexibility & efficiency in energy use
Hydrogen is a key player in the global energy transition due to its unique properties that make it a promising alternative energy source. The shift to zero-emission or low-CO₂ energy solutions is imperative to replace fossil fuels, and hydrogen offers a viable solution. With a significantly higher energy density compared to fossil fuels, hydrogen can store more energy per unit weight, making it particularly efficient. Moreover, its greatest advantage lies in its environmental friendliness: when hydrogen is burned, the only byproduct is water, resulting in zero harmful emissions.
Hydrogen addresses challenges that other technologies cannot fully overcome. It can store excess energy generated from renewable sources like solar and wind power, which often produce more energy than is immediately needed. Additionally, hydrogen is a versatile energy carrier with applications ranging from industry to transportation to power generation. Unlike batteries, which have limited storage capacity and shorter durations, hydrogen enables much larger-scale energy storage, opening up new possibilities for a sustainable, flexible, and comprehensive energy supply.


The color theory of hydrogen – what types of hydrogen exist?
Hydrogen is classified in different colors – depending on its production and environmental footprint. These “colors” of hydrogen – grey, green, blue and turquoise – illustrate how climate-friendly or harmful the process of hydrogen production is, with each type of hydrogen bringing its own specific benefits and challenges. In the transition to a climate-neutral economy, a combination of these technologies will be necessary to achieve global climate targets:
- Grey hydrogen is produced from fossil fuels (natural gas, coal) and has high CO2 emissions that are released unhindered into the atmosphere. Mainly used in industry, e.g. for the production of ammonia and methanol.
- Blue hydrogen is also produced by steam reforming of natural gas, but the CO2 emissions are captured and stored in underground reservoirs. Serves as a bridging technology to reduce greenhouse gas emissions in the short term until sufficient green hydrogen is available.
- Turquoise hydrogen is produced by thermal cracking of methane, creating solid carbon and avoiding CO2 emissions. Potential for near CO2-neutral production, especially if renewable energy is used; solid carbon can be reused in industry.


Green hydrogen – the climate-friendly energy source of the future
Green hydrogen is produced through electrolysis, a process that uses renewable electricity from sources like wind and solar power to split water into hydrogen and oxygen. This makes green hydrogen a completely climate-neutral energy carrier, playing a crucial role in the transition to a CO₂-neutral energy future.
Green hydrogen has a wide range of applications: In mobility, it powers fuel cell vehicles, offering a clean and efficient alternative to fossil fuels. In industry, green hydrogen can be used as a versatile energy supplier for various processes. Additionally, it can be stored for later use, helping to balance energy supply and demand.


While batteries are specifically optimized for fast energy supply and natural gas is increasingly criticized for its environmental impact, hydrogen impresses with its remarkable flexibility. It offers a wide range of applications and shows its full potential especially in areas that require high energy densities and long storage times, such as heavy-duty transportation or stationary energy storage, because one of the biggest challenges with renewable energies such as wind and solar power is their volatility.
Hydrogen can play a decisive role here by using surplus electricity to split water into hydrogen and oxygen through electrolysis. The hydrogen produced can be stored and converted back into electricity when needed, enabling reliable and sustainable energy storage.
In heavy goods transport and industry, hydrogen offers an emission-free alternative, especially in sectors where battery-powered technologies are reaching their limits. The high energy density of hydrogen makes it an ideal fuel for heavy vehicles and energy-intensive processes that previously relied on fossil fuels. This contributes significantly to the reduction of CO₂ emissions, which is crucial for achieving global climate targets.
