Hydrogen(H2)-powered fuel-cells work by converting the chemical energy in the stored gas to electrical energy via an electrochemical process. This creates electricity to power the vehicle.
This process is extremely efficient – nine litres of water can produce one kilogram of hydrogen. In turn, that one kilogram of hydrogen contains 33 kilowatts of energy which translate to a range of around 100 kilometres.
When used in a fuel cell, hydrogen produces zero emissions, the only bi-product being water vapour. The UK government has ambitious plans to reduce greenhouse gas emissions and improve air quality.
These targets can only be achieved through a transition to a low carbon economy. The application of hydrogen fuel cells in transportation introduces the potential use of a truly zero-emission fuel enabling significant improvements in air quality.
See for yourself how our hydrogen vehicle refuelling station in Kittybrewster, Aberdeen is using proven technology to power one of Europe’s largest fleets of hydrogen buses.
Hydrogen versus fossil fuels
Hydrogen is the most commonly occurring element in nature. And unlike fossil fuels such as crude oil or natural gas, it will never run out. Hydrogen does however need to be produced – today, mainly by primary energy sources including oil and gas, but increasingly through renewable energy for a sustainable future. With this in mind, and knowing that fossil energy sources will only become scarcer and scarcer, we have been intensely engaged in the use of hydrogen as an emission-free fuel for over 25 years. Moreover, we have systematically strengthened our position as the technology leader for the eco-friendly application of hydrogen in the mobility sector.
Our cutting edge offering in this area is based on the development of innovative technologies, e.g. for the efficient compression and safe fuelling of hydrogen. This is what makes us an ideal partner for all who want to advance the use of hydrogen as a fuel – especially where the creation of a comprehensive H2 fuelling station infrastructure for cars and buses is concerned. In addition, we offer an extensive technology portfolio for fuel-cell-powered material handling vehicles.
