The Games start in seven days. The 20 hydrogen buses at National Express should be running by then, and a few have been tested on route 51 passing the Stadium. Also 10 hydrogen cars from ToyotaGB have been obtained by Adelan Ltd to assist visitors. These are green machines. In addition, more than 100 Teslas and other battery vehicles to transport athletes have been obtained and are recharged at Aston University. The problem is that these are being charged from diesel generators and the emissions are released within the Clean Air Zone. Who thought of that crazy idea? More than a MW of nasty diesel emissions provided by Aggreko, the Games Pollution Partner.
