HYDROGEN

 

Hydrogen is a non-toxic and very energy-efficient gas: it is twice as efficient as petrol or natural gas, and three times as efficient as diesel. Hydrogen can run several engines and turbines. Through fuel cells, hydrogen directly generates electricity. The only residue resulting from this process is pure water in the form of steam.

 

A way of generating hydrogen is water electrolysis, using the electricity supplied by renewable energy. This hydrogen called “green hydrogen” allows the storage and re-use of this renewable energy, pollution-free. Hydrogen therefore becomes an energy carrier for storage that solves the inconvenience of intermittence characterizing solar or wind energy.

CEOG follows this process to generate clean power, even at night or during cloudy days with reduced sunshine.

 

Today, hydrogen is used and manipulated daily at a large scale in various industries. Its use is regulated and industrial risks have been under control for over 100 years.

 ENVIRONNEMENTAL FOOTPRINT

 

CEOG’s environmental footprint is low. The operating principle of a hydrogen energy chain (electrolyzer, hydrogen storage, fuel cell) doesn’t require many resources that need to be extracted and transformed. Nor does it require a polluting electrochemical process generating hardly recyclable products either.

A hydrogen energy chain is mainly made of reusable metal. It uses water, produces oxygen and hydrogen, and generates pure water at the end of its life cycle.

 

The infrastructure mostly being able to fit in containers, the installation onsite remains simple and needs little civil engineering. This reduces even more its environmental impact.

Containerisation also allows an easier dismantling at the end of the power plant’s life cycle. Dismantling too will have a limited impact as the infrastructure is mainly made of metal, which will be recycled through the conventional metal sector.

Finally, CEOG’s yearly power production will be about 50 GWh. This corresponds to the average power consumption of 10,000 homes a year.

According to the ADEME (French Agency dedicated to Environment and Energy Saving), in comparison with a conventional diesel thermal power plant delivering an equivalent service, CEOG saves the release in the atmosphere of 39,000 tons of CO2 a year.
