Current issues

Carbon Dioxide

Nitrogen Oxides

Carbon Monoxide

Particulate matter

Other toxins

• 1bn vehicles worldwide each emit 5 tonnes of CO2 per year• Legislation for 1.5 million ZEVs on California’s roadways by 2025

What are fuel cell vehicles?Hydrogen

Storage TankPower

Control Unit

Fuel Cell Stack

Electric Motor

Fuel Cell: Hydrogen + Oxygen → WaterCombustion: Petrol + Oxygen → Water + CO2 + CO + NOx + Particles / toxins

Why are they being developed?

• Zero emissions and better efficiency

• Direct replacement for current vehicles

• Opportunity to use renewable energy
