Hydrogen production

We always have to make our own hydrogen and there are different ways of doing this. The least environmentally friendly ones are unfortunately the cheapest. Hydrogen production is one way of storing surplus electricity when renewable power stations are running at full capacity but there is no demand.

Use of hydrogen in cars

Hydrogen has the highest combustion energy per unit mass of any fuel. A hydrogen car is essentially an electric car that uses the conversion of hydrogen in the fuel cell to generate electricity. The drive is locally emission-free with ample range and fast refueling.

Fuel cell

The fuel cell converts hydrogen into electricity. A kilogram of hydrogen will give a car a range of around 100 kilometres. Fuel cells are now technologically advanced and safe devices. The relatively high cost of fuel cells has so far prevented mass deployment.

Hydrogen storage

Because of its low density, hydrogen must be stored compressed in cylinders. These must be pressure-resistant, shatterproof and very tight to prevent hydrogen leakage. Compressing hydrogen itself is energy intensive. Cryogenic storage tanks with liquefied hydrogen are also used for stationary storage.

Hydrogen infrastructure

Hydrogen infrastructure exists in the form of subsidised pilot projects, but also developing commercial infrastructure. The number of hydrogen vehicles and refuelling stations is growing year on year. Production costs and purchase prices are falling hand in hand.

Electric car design

How are electric cars different? Some parts of the car are missing, others are missing. The developer of DEVINN s.r.o. summarizes the basic specifics of the electric car design and its features in a simple and factual way.

ELECTRIC CAR BATTERY - BASIC PARAMETERS

What most of us call "batteries", for example "pencil batteries", are actually cells. We only refer to a battery as a set of electrically connected cells. The basic parameters of a battery are minimum and maximum voltage, capacity and internal resistance.
