Good news for optimists.

Good news for the Climate Change Conference: net-zero in the second half of the century is achievable

At thyssenkrupp, sustainability is part of our business model. Climate protection is one of our company’s strategic goals. We’re committed to the targets of the Paris Agreement. And we believe that net zero greenhouse gas emissions in the second half of the century is an achievable goal.

For this we will need to avoid greenhouse gas emissions wherever it makes sense. This will mean among other things making increased use of renewable energies. However, the volatility of renewables presents consumers with new challenges. Energy from renewable sources is not always available in consistent amounts. Luckily storage technologies are already available to manage intermittency.

Where it does not make sense to avoid greenhouse gas emissions, they can be recycled. With the right technologies we can capture CO2 and reuse it as a raw material. thyssenkrupp is already working very successfully on this.

We’d like to tell you more about these technologies and other good news stories on this website. You’ll see that where climate protection is concerned, technology is part of the solution.

Technologies for climate protection


#1 Carbon2Chem

Recycling CO2

With Carbon2Chem we aim to convert steel mill gases – including the CO2 they contain – into base chemicals. The steel mill gases will be made into starting materials for the manufacture of fertilizers and fuels. The greenhouse gas would then no longer be discharged into the atmosphere. And: The energy needed for the conversion process will also come from renewable sources. 16 further partners from the areas of basic and applied research and various sectors of industry are involved in the project, which is being funded by Germany’s Federal Ministry of Education and Research.

Smart Energy Storage

#2 Smart Energy Storage

Saving energy

The share of renewables-based electricity is growing, while the cost is falling. We now need to develop efficient storage technologies because energy from renewable sources is not continuously available at the same level. Our solution: Smart Energy Storage Systems that can bridge gaps in supply. Redox flow batteries can store several hundred megawatt hours of energy and make it available again on demand. A second large-scale technology is water electrolysis, in which electricity is used to break down water into hydrogen and oxygen. The hydrogen can be stored as an energy source and converted back into electricity when required.


#3 Oxyfuel

Capturing CO2

We have developed a solution which efficiently captures CO2 during cement production. The Oxyfuel process is the combustion process used to burn limestone to produce cement clinker. By using pure oxygen instead of ambient air, we can eliminate nitrogen from the combustion process so that highly concentrated CO2 is produced. This gas is far easier to capture and recycle than waste gas from a conventional combustion system – and can be used for example as a starting material for the production of chemicals.


#4 Envinox

Converting greenhouse gas

Laughing gas is around 300 times more harmful to the environment than CO2. It is produced among other things in the manufacture of nitric acid, an important raw material used among other things to make fertilizers. With our EnviNOx process, laughing gas can be almost completely removed from nitric acid production. It also converts the nitrogen oxides contained in the waste gas into water and nitrogen. Around the world roughly 30 EnviNOx systems are now in operation, reducing emissions of nitrogen oxides by around 20,000 tons and laughing gas by around 56,000 tons.


#5 BioTfuel

Rethinking fuel

With BioTfueL we have teamed up with European partners to produce climate-friendly biodiesel and biokerosene. These second-generation biomass fuels are of extremely high quality and reduce CO2 emissions by up to 90 percent compared with conventional fuels. BioTfueL fuels are suitable for use in standard diesel cars, trains and ships as well as jet engines. They are made from waste materials such as straw, grass cuttings, forest waste, or dedicated energy crops, i.e. biomass sources that do not compete with food crops.


#6 E-Mobility

Eco-friendly motoring

There are two factors that decide the range of an electric vehicle: the capacity of the batteries and the efficiency of the motor. So we’re working on both at the same time: Together with partners from research and industry, we’re developing a new generation of battery cells using a revolutionary design. At least as promising is the work we are carrying out on electric powertrains. For hybrid and electric vehicles we have optimized our special steels to significantly improve the efficiency of the motor and as a result also the range of the vehicle.

Going climate-neutral

"All the investments we make serve the same goal: a better future. We say under certain conditions “net zero” is doable."

Markus Oles, Head of Innovation Strategy and Projects.

"The climate targets are achievable – technology is the driver. Climate protection isn’t a constraint for technology companies, it’s a genuine business opportunity."

Thomas Fußhöller, Head of Sustainability, Environment and Energy Management.
