Green hydrogen is produced when renewable energy is used to power water electrolysis to split water into hydrogen and oxygen.
Hydrogen can be produced using water electrolysis
An electrical current is passed through water using two electrodes
Hydrogen appears as gas bubbles at the cathode – where the electrons enter
Oxygen appears as gas bubbles at the anode
When the electric current is generated by a renewable source – such as solar or wind –
the hydrogen produced is referred to as green hydrogen. This is because there are no
greenhouse emissions associated with the end to end process.
Hydrogen as a Fuel
Siemens GeoPura are actively looking for renewable energy producers who want to
maximise their renewable energy production and generate green hydrogen at their
Our reliance on fossil fuel is largely due to the ease in which it enables us to release and
use energy. Renewable energy is not quite as convenient, as generation often relies on
specific conditions, especially with regards to solar or wind. Green hydrogen is an
effective way of storing renewable energy.
If your renewable energy production, or return on investment, is being limited by grid
connection capacity or fluctuations in demand, being able to divert capacity to
producing green hydrogen is the ideal solution. It could also enable you to expand your
We install industrial scale electrolysers across the globe with the capability to convert
four litres of water into the hydrogen fuel equivalent of a litre of petrol every minute of
The Future is Green Hydrogen
Green hydrogen is being widely considered as the fuel of the future as no greenhouse
gases are produced during its manufacture and no greenhouse gases are released
when it is used a fuel.
When ‘burnt’ in a fuel cell hydrogen releases heat, electricity and pure water is the only
In road transport a stack of fuel cells can be used to power an electric motor directly or
generate electricity to run 1000s of EV chargers. A fuel cell stack can also be used as an
off-grid generator to power or charge any electrical device or system.
The opportunities for hydrogen fuel are endless.
