More than 500 students from 111 schools from across the capital took part in the challenge by completing a series of educational, interactive online lessons during their science classes.

Of those 33 pupils were chosen to represent their schools at the challenge’s grand final at City Hall.

The youngsters and their teachers took part in hands-on experiments to show hydrogen technology in action on a miniature scale, with first, second and third cash prizes on offer for the best work.

Kit Malthouse, deputy mayor of London, who is chair of the London Hydrogen Partnership, said: “It is great to see school kids learning about new technologies that have the potential to drastically improve our environment in the future.

“Not only does the challenge bring science alive, but it also helps to nurture young people’s passion for the environment.”

Amelia Mucahy, 12, from St Thomas More Roman Catholic Comprehensive School in Greenwich, took part.

She said: “I really enjoyed learning something new and it was fun.”
