CYTOK®s Power-to-Gas Technology
energy reimagined
Learn how the CYTOK power-to-gas (ptg) technology is revolutionizing the use of renewable energy. With our advanced, emission-free conversion in Rostock, we are setting new standards for independent energy supply and climate protection. Discover how we are shaping the energy of the future with our patented method.

Revolutionary energy storage through methanation
Our power-to-gas technology sets new standards in the storage and utilisation of renewable energies. The patented solution enables the conversion of surplus electricity into synthetic natural gas (SNG) – a storable, versatile gas that is superior to fossil natural gas, particularly in terms of sustainability.
With a closed CO₂ cycle and our modified oxyfuel process, we guarantee emission-free utilisation. While battery storage systems are limited in terms of capacity and cost-effectiveness, our technology allows energy to be stored almost indefinitely and cost-effectively.
Our CYTOK® power-to-gas technology is:
economical
efficiency
safe
emission-free
TÜV-certified
durable and low-maintenance
redundant to existing systems

A brief explanation of how our power-to-gas technology works:
Electrolysis: Surplus sustainable electricity is used to split water into its components hydrogen and oxygen.
Methanation: The hydrogen obtained reacts with CO₂ in a chemical process to produce synthetic methane.
Closed CO₂ cycle: The resulting CO₂ is completely recycled, thereby avoiding emissions.
Oxyfuel process: This innovative process allows synthetic natural gas to be burnt with zero emissions.
Flexible and redundant storage capacity: The synthetic methane can be stored in standard natural gas storage facilities and used as required.
Modified oxyfuel process
CO₂ cycle and emission-free combustion
Our patented oxyfuel technology is a decisive breakthrough in the climate-neutral use of synthetic natural gas. Instead of using ambient air, combustion takes place using pure oxygen from electrolysis. This means that no nitrogen oxides or particulate matter are produced, which occur in conventional combustion processes.
The CO₂ released in the process is not released into the atmosphere, but is fed back into a closed cycle. It is used again as a raw material for methanisation, completely avoiding fossil CO₂ emissions. The further use of the CO₂ is also known as CCU (carbon capture and utilisation).


The advantages of our power-to-gas technology for you
100% emission-free: no CO₂ emissions, no nitrogen oxides or particulate matter
Unlimited storage capacity: no scaling limits, unlike battery storage systems
High efficiency: maximum energy utilisation thanks to intelligent energy management systems
Redundancy & security of supply: utilisation of existing gas infrastructure for stability
Sector coupling: combining electricity, heat and mobility in one system
We thus create a secure, independent, sustainable and economical energy supply and energy storage.
