HYDROGEN OR BATTERIES? Which is best?
Hydrogen Vs Batteries Hydrogen cars have long ranges RANGE: 700+ km. REFUELING : In a few minutes. CHALLENGE: Few filling stations and expensive production method. ADVANTAGE: Hydrogen can store energy from renewable sources such as solar cells and wind turbines. Battery-powered cars get their energy from the grid RANGE: A maximum of 500 km. RECHARGING: 1-12 hours. CHALLENGE: Short range and very long charging time. ADVANTAGE: Communicate with the future grid, so the power can be as cheap as possible. Hydrogen stores energy well The major sales argument for hydrogen is its ability to store energy. Hydrogen contains 120 mega joules of energy per kg – compared to 44 for petrol. At best, batteries can store 2-3 mega joules per kg. a fully fueled hydrogen car has a range of 6-700 km, which is about the same ...
