What is Green Hydrogen?

Green hydrogen is produced by using electricity to break water (H2O) down into its component elements – hydrogen (H2) and oxygen (O2), using technology called an electrolyser (pictured below)

The electricity is powered by renewable sources, such as wind or solar, and therefore zero CO₂ emissions are generated in this process. Hartwood is an example of this, producing renewable energy through wind.

Therefore, unlike blue and grey hydrogen, there is no greenhouse gases associated with its production. Green hydrogen can be used to provide a range of different zero carbon alternatives; it can be applied to heat, power and transport.


Green hydrogen is part of the solution to meet net zero objectives.  

The green solution to end fossil fuels

The UK has committed to tackling climate change and aims to reach net zero carbon emissions by 2050. This means businesses across the country need to urgently find ways to remove carbon emission from their operations.

In the last decade the world has made enormous progress in delivering new zero emission ways of producing electricity including new solar and wind projects.

Green hydrogen is an exciting and innovative solution which can drive down these emissions and futureproof our vital industries. To deliver on green hydrogen projects and commitments, a portfolio of renewable energy projects across the UK is required.  These renewable energy projects can be co-located at the site of hydrogen production  or in other appropriate sites, such as Hartwood, where there is an abundant wind resource. Protium is developing renewable energy projects across the UK to provide green energy for hydrogen production in order to decarbonize industrial processes and operations.


It can be stored and used when required.


It can be transported over significant distances.


It can be used for multiple energy requirements including heating, mobility and power.
