Oxy-Hydrogen gas is one of the main fuels of the future. Basically, it is water turned into a gas by the use of electricity. The process and the resulting flame are CO2-free. OPAi works on an installation that generates heat and electricity in buildings and has filed for patent.
It is not that the technology is new: The invention is the combination of existing technologies into a new concept that can help in the transition towards the decentralised production of energy from renewable sources.
