If young people hold the future of our planet in their hands, then we're on the right track if competitions like the London Schools Hydrogen Challenge continue to flourish.

Kit Malthouse, the Deputy Mayor of London, personally congratulated young Londoners for successfully taking part in the London Schools Hydrogen Challenge – an online science competition run by the London Hydrogen Partnership and developed by dbda.

The Challenge, sponsored by Air Products and supported by Transport for London, encourages 11-14 year old students to find out more about hydrogen technology, one of a range of less polluting fuels that wider use of in the future could help to improve air quality, and cut the carbon emissions which cause climate change.

More than 500 students from 111 London schools took part in the Challenge by completing a series of fun, educational and interactive online lessons during their science classes. 33 lucky pupils from across London's boroughs were chosen to represent their schools at the challenge's Grand Final at City Hall where pupils and their teachers took part in hands-on experiments to show hydrogen technology in action on a miniature scale.

Deputy Mayor of London, Kit Malthouse, who is Chair of the London Hydrogen Partnership said: "Not only does this bring science alive in a fun way, it also helps nurture young people's passion about the environment. I congratulate all these young Londoners for embracing this Challenge with such imagination and enthusiasm."
