Green Hydrogen

What is Green Hydrogen?

Green hydrogen is produced when renewable energy such as solar or/and wind energy is used to break down water into oxygen and hydrogen atoms. This process is called electrolysis with water as its only waste product.

Compared to grey and blue hydrogen which are produced from fossil fuels in a process that emits/releases greenhouse gases, green hydrogen production technology is clean and without emissions.

The importance of Green Hydrogen

Green hydrogen has the greatest potential for clean energy generation, transportation, and storage toward achieving the global target of net-zero carbon emissions and energy sustainability.

The technology used to produce green hydrogen from renewable energy sources is known as Power-to-Gas (P2G).

P2G uses electric power to produce gaseous fuels. Green hydrogen fuel is produced when direct current from renewables is used as a source of power to electrolysis of water.

Power-to-hydrogen can be used directly as natural gas to generate electricity, or as fuel cell in transport or industry.

The benefits of Green Hydrogen

Sustainability:

Green hydrogen energy reduces the dependency on fossil fuels, promotes the use of local resources, and eliminates the intermittency associated with other renewable energy sources.

Decarbonization:

The technology used for green hydrogen production is free from greenhouse gas emissions that have become difficult to combat especially in industries that use high energy density fuels thereby contributing to the global net-zero carbon target.

Efficiency:

Green hydrogen can be produced anywhere there is water and electricity, and transformed into electricity, heat, or a carrier like ammonia for direct electrification, space heating, transportation, or storage.

High Carbon

Brown Hydrogen

Made → Coal (Gasification) CO2 is emitted into the environment (Most environmentally damaging).

High Carbon

Grey Hydrogen

Made →  Natural Gas (SMR) CO2 is emitted into the environment (The most common form of hydrogen).

Low Carbon

Blue Hydrogen

Made → Natural Gas (SMR) CO2 is captured and stored.

Zero Carbon
Zero Carbon
