Hydrogen bus

Hydrogen and fuel cells

We are using hydrogen to reduce air pollution in two main areas; hydrogen vehicles and fuel cells in buildings.

Hydrogen

We want London to be a world leader in hydrogen and fuel cell activity.

Hydrogen is a universal fuel that will play a major role in our clean, sustainable energy future. Coupled with fuel cells, hydrogen will increasingly provide us all with clean and secure energy to power our cars, buses, homes, businesses and personal smart technologies.

Excitingly, if the hydrogen itself is produced from a carbon-neutral source such as London's waste, solar or wind power, we have the potential for carbon-neutral and emission-free energy.

About Hydrogen and Fuel Cells

Emission-free transport

Hydrogen fuel is a great way to power public and private transport in London. The only emission is water vapor which means that no carbon dioxide or other air pollutants are relased into the air.

We know it works too, as our RV1 bus already runs on it.

Fuel cells in buildings

Hydrogen and fuel cell units can be used to generate heat and power for buildings, mobile generators and back-up power. 

Larger fuel cell units run off natural gas but are also hydrogen ready. Fuel cell technology offers a means of decarbonising energy supplies in buildings in a wide range of situations. Key characteristics of fuel cells are:

  • Zero-emission – allowing indoor use and use in restricted spaces, areas where air quality is a concern, or in environmental monitoring applications. Replacing diesel generators with these products leads to health benefits for workers nearby.
  • Low noise – operation in noise-sensitive environments, or those where noise restrictions apply is possible.
  • Portable – lightweight, compact products that are highly portable.
  • Vibration-free operation – particularly advantageous for sensitive environmental monitoring, or for increased comfort in working or leisure environments.
  • Long unattended run times – systems designed for extended periods of unmanned operation (a major cost saving compared to other solutions). High energy density compared to battery-based solutions.
  • Zero contamination risk – unlike solutions that rely on liquid fuels, there is zero risk of contamination from fuel spillage.

Hydrogen London

Through Hydrogen London we are bringing hydrogen and fuel cell technology to London, securing new jobs and investment, supporting London's green economy, improving energy security and air quality, and reducing carbon dioxide emissions.

Hydrogen London is a partnership consisting of experts from government, business and academia. Since being established by the Mayor of London in 2002, Hydrogen London has been at the heart of London’s hydrogen and fuel cell industry – driving forward growth and investment to make London a leader in the sector.

Through its ground-breaking projects, Hydrogen London has demonstrated that hydrogen and fuel cell technology is a viable option for powering the capital.

The partnership is building upon these successes to ensure that London is a capital for hydrogen and fuel cell technology.
