Hy2green stands for energy from natural energy sources such as wind, sun or hydropower stored in hydrogen. It means energy stored without any emissions and with natural raw materials. Our Hy2green system turns locally produced electricity from renewables into hydrogen and stores it very stably and safely in metal powder. On demand, the hydrogen can quickly be released and converted back into electricity. Watch the video to see how Hy2green works and what else it can do.
Energy savings and local energy production from natural, carbon-free energy sources are at the heart of CO2 reduction in the building sector. However, the generation of sustainable energy does not always correspond to the actual demand since sun, wind and water are often not sufficiently available. This continues to make it necessary for the end consumer to purchase costly energy from the electricity provider. The Hy2green storage system enables compact and secure energy storage, even over a longer period of time.
Sun, water or wind – just as long as they are natural and sustainable. The Hy2green storage system is the ideal solution to make better use of locally generated energy from renewables and to become energy self-sufficient.
Hydrogen in combination with metal powder results in metal hydride. It is particularly suitable for storing hydrogen long periods and compactly. The benefit: With the energy from summer, you can make light, have a shower and heat your house in winter.
The Hy2green system supplies electricity and heat. This increases the overall efficiency of the system without any harmful emissions – only water and oxygen are left behind.
The metal powder-based Hy2green storage is significantly smaller than other energy storage types, whether for battery technology that would be suitable to store the same amount of energy or for other gaseous hydrogen storage systems.
Renewable sources of energy are converted into the energy source hydrogen by means of electrolysis.
It is compactly bound in a storage tank with metal powder at low pressure in a stable and safe manner as metal hydride.
The connection can be released again as required by simply adjusting the pressure and temperature. The hydrogen flows to a fuel cell, where it is converted into electricity.
The resulting waste heat is collected by the integrated heat management system and fed into the heat cycle of the house.
Only oxygen and water remain at the end – an efficient zero-emission electrical and thermal power plant.
With the opening of the Knappenhaus project, the Hy2Green storage system has now taken the step from pilot project to endurance testing under the toughest everyday conditions in the South Tyrolean Alps and has been running since the beginning of 2019.
Our aspiration is clear: this storage technology will contribute globally to a better use of renewable energy sources and to a high security of supply without CO2 emissions, even in remote locations. This is what we are planning to do in the near future:
Enertour offers a look behind the scenes of outstanding energy projects in South Tyrol by means of field trips. We want to be involved and share our knowledge.
For us, 2019 is all about continuous operation. Findings are important for the next projects in order to make our system even more compact, convenient and economical.
The Hy2green system is suitable for all three carbon free energy sources – water, sun, wind. We can already do water, now we are looking for suitable projects to scale our system in terms of energy source and size.
Metal hydride storage allows a wide range of applications. The journey of hydrogen as an energy carrier is only just beginning. Ships, self-sufficient mini power plants, commercial vehicles – we are keen to explore the next.
