Case Study: Cenex LCV BEV Charging

Customer: Toyota

Toyota GB showcased their range of zero-emission vehicles at the Cenex LV event. To demonstrate their vision of a 100% zero-emission future, they wanted to provide off-grid charging for their BEVs (battery electric vehicle) using a hydrogen fuel-cell generator, instead of a diesel generator.

Switching to BEVs alone will not decarbonise transport if the electricity source is not clean. This showcase aims to demonstrate a viable zero-emission off-grid BEV charging solution that can be deployed across the industry.

The Challenge

BEV charging infrastructure is scaling up. However, these chargers require a huge amount of electricity, and grid connection can often become a challenge due to location as well as demand constraints - with some operators having to power their chargers using diesel generators.

Toyota want to showcase their zero-emission vehicles in a 100% zero-emission setting during the event. They don't want to have diesel generators powering their chargers in the background, they want the audience to see that the source of electricity is green.

Fuel cells produce only water as a waste product, meaning that there are zero CO2e or NOx emissions at point of use, whatever colour of hydrogen used as a fuel. They also produce practically no noise.

  • But how do end users like Toyota access this solution?
  • Can this be set up within a tight event timeframe?
  • How can safety be guaranteed, especially for such a public event?
  • What carbon impact could adopting hydrogen have in the real world?

Explore Potential

Hydrogen has the potential to accelerate BEV infrastructure by providing either temporary power for projects awaiting grid connection, or long-term power for off-grid projects.

Paving the way for large-scale replacement of a fossil fuel.

Scale Green Hydrogen

Groups like Toyota have the scale of demand to secure lower cost supplies of green hydrogen generated by emerging UK hydrogen producers.

Working Together

Infrastructure providers and vehicle manufacturers could work with hydrogen industry stakeholders like Hydrologiq to build a practical roadmap to replacing diesel with alternative power sources like solar, wind, batteries and hydrogen.​

More Trials

Longer trials where hydrogen is directly replacing diesel can showcase the positive carbon impact of using hydrogen.​

"2023 heralds a new age for generator power. The diesel engine has been around since the 1800s, so it's about time we embraced new technology to respond to a modern world where air quality and noise pollution are top of the agenda. Everyone at Hydrologiq is proud of our collaboration with Toyota to take tangible steps towards this new reality today."
