clean energy for the future

Hydrogen at Wolftank

Hydrogen is a very versatile and non-polluting energy carrier: its use produces only water. It is also very light and has an extremely high gravimetric energy density. Green hydrogen is a “game changer” for decarbonization. Wolftank Group provides long-standing expertise, invests in R&D and builds the necessary hydrogen infrastructure for an emission-free future.

Hydrogen is virtually everywhere, accounting for an estimated 75% of the mass of the entire universe. Nevertheless, it only occurs in bound form, as a component of larger chemical compounds such as water. Thus, hydrogen must be produced with an additional energy input and is therefore a secondary energy carrier, comparable to electricity or heat. 

Hydrogen is a very versatile and non-polluting energy vector: its use only produces water. It is also very light and, at the same time, has an extremely high gravimetric energy density: one kilogram of hydrogen contains an enormous amount of energy, making it an efficient and very lightweight energy carrier.

There are different methods of hydrogen production, which use several primary energy sources. Depending on the origin of the energy used in the process and the associated emissions, the hydrogen produced can be classified into different “colours”. The “green” or “renewable” hydrogen is the most interesting, since its manufacturing process does not cause direct carbon dioxide emissions, neither during production nor during combustion. 

“Green” hydrogen is produced from renewable energy sources and with low (or zero) associated pollutant emissions. The best acknowledged green hydrogen production method is the electrolysis of water, which consists of separating the water’s molecule into its components (hydrogen and oxygen) by applying electric current in an electrochemical device called an electrolyser.

In the context of climate change, the Paris Agreement (2015) established a global framework by limiting global warming to well below 2°C and continuing efforts to limit it to 1.5°C. To achieve this target, science suggests that humans would need to neutralize their impact on the global climate by 2050 at the latest.

Following this advice, the European Union has developed its “Green Deal” roadmap, which aims to achieve climate neutrality in 2050. In September 2022, the European Union took a historic decision: It is establishing a EUR 3 billion European Hydrogen Bank that will further boost the hydrogen market and develop it from a niche to a mass market.

Hydrogen will be a “game changer” for Europe. Within this framework of necessary decarbonisation, green hydrogen plays a key role worldwide.

to 2024
Production of hydrogen from non-fossil (green) sources reaches a total capacity of 6GW (1 million tons).
2025 to 2030
Increase total power to 40GW
within 2050

September 2022 announcement

EU Hydrogen Bank is created with an initial capital of € 3 billion to help the market, which needs to reach the EU’s proposed 2030 target of producing 10 million tonnes of renewable hydrogen each year.
