# DEUTZ Hydrogen - The key component of future energy supply : DEUTZ AG

Fuels of the Future  Hydrogen -
 A clean source
 of energy
=========================================

Hydrogen is a naturally occurring chemical element. It is a key building block for a climate-friendly energy supply of the future.

Technology of tomorrow is having an impact today
------------------------------------------------

Faced with the global climate crisis, countries around the world are taking far-reaching measures to meet their climate targets and limit global warming to 1.5 degrees Celsius as set out in the Paris Agreement. The development of alternative power systems plays a central role, with hydrogen as a clean energy source receiving particular attention.

Hydrogen holds huge promise as a future energy source. And even today, it has the potential to reduce environmental impacts when used as a fuel. This is why DEUTZ has been intensively involved in the pioneering technology of [hydrogen combustion engines](https://www.deutzge.sbs/slovakia/en/products/hydrogen-engines/) for many years now. So intensively that we already have one in commercial production.

FAQ

#####  How is hydrogen produced?

Hydrogen is a naturally occurring chemical element and a key component of the future climate-friendly energy supply. Hydrogen usually exists as a molecule and can be stored, transported and used as an energy carrier in gaseous or liquid form for energy conversion (reconversion into electricity). Hydrogen is usually found in nature in the form of compounds and must therefore be separated from a hydrogen-rich starting material using energy. These may include:

- Natural gas
- Other hydrocarbons such as oil
- Biomass
- Water
- Other compounds containing hydrogen (e.g. ammonia NH3)

Chemical, electrical, thermal or solar energy can be used to separate these substances and produce pure, uncombined hydrogen. Depending on the production process, the hydrogen produced is colloquially described by different colours.

#####  What are the colours of hydrogen and what is their meaning?

Hydrogen is a very flammable gas. However, it is assigned different colours depending on its origin.

**Green hydrogen** is produced by electrolysis of water. This is done using electricity from renewable energy sources that do not release CO2 into the atmosphere. No CO2 is released during the production of green hydrogen.

**Grey hydrogen** is usually produced from fossil natural gas by steam reforming. This produces about 10 tonnes of CO2 per tonne of hydrogen. The CO2 is released into the atmosphere. This hydrogen needs to be replaced with climate-friendly hydrogen.

**Blue hydrogen** is grey hydrogen produced by storing the CO2 instead of releasing it into the atmosphere (CCS, Carbon Capture and Storage). This process can store up to 90% of the CO2.

**Orange hydrogen** is hydrogen produced from waste and residual materials. It is considered CO2 neutral.

**Turquoise hydrogen** is hydrogen produced by thermal decomposition of methane (methane pyrolysis). Instead of CO2, it produces solid carbon that does not escape into the atmosphere. The methane pyrolysis process is still under development.

**White hydrogen** is found in natural deposits. Whether it can be used in the future is still unclear. The formation of white hydrogen and its transport in the Earth's crust are still poorly understood.

#####  How can hydrogen be stored?

In its pure form, hydrogen can be stored as a compressed gas in pressurised containers or as a cryogenic liquid in insulated containers. It can also be chemically bonded and stored in the form of synthetic fuels or LOHC (Liquid Organic Hydrogen Carrier). In this way, the bound hydrogen can also be stored under normal conditions in conventional tanks for crude oil and petroleum products.

Existing underground pore or salt cavern storage facilities can also be considered as stationary hydrogen storage for gaseous and chemically bound hydrogen. These are currently used to store natural gas and crude oil.
