Changes in our climate are becoming increasingly visible as a result of more frequent extreme weather events and the deterioration of the situation of entire ecosystems. Man-made greenhouse gas emissions are considered to be the main culprit. In order to significantly reduce these emissions, we must completely switch our energy supply from fossil fuels to renewable energies. For this energy transition we need powerful and inexpensive energy storage systems.
Only the GroNaS technology has the potential to make the energy transition technically possible and economically efficient.
GroNaS large sodium sulfur batteries for electric energy make the energy revolution an affordable reality.
GroNaS has developed a disruptive technology that reduces the cost of electric energy storage to a tenth of the cost of any other technology that is currently available on the market. With a maximum price of about 900 USD per kilowatt power capacity, including an exemplary storage capacity of 336 gigawatt hours, only a comparably inexpensive, specific investment is necessary to build a large GroNaS energy storage.
“Earn money with large energy storage”
Our vision is the efficient and profitable storage of electric energy in an industrial scale, for the consequent supply of our society with renewable energy, provided by large GroNaS energy storage systems in the grid.
What is special about GroNaS storages?
Basically, we use the proven principle of a sodium-sulfur-accumulator, which has been in use since the eighties. This principle works with the electrolysis and synthesis of sodium sulfides. Sodium and sulfur are two very cheap, uncritical and high-energy materials.
We have redesigned this principle from the ground up. Power and storage capacity (energy conversion and storage) were separated.
With our newly developed and patented energy converter, we can achieve scalable power capacity outputs between 20 and 1000 MW and scalable storage capacities from 8 to 336 GWh. Over the entire storage and retrieval process we achieve an efficiency rate of 75 to 90%.
