The world is in full swing with a green transition, which aims to substitute fossil fuels in the energy supply with renewable energy sources. Wind and sun are high on the list.
The blades of the wind turbines spin around and produce power. Another day is completely quiet. It is nature that determines whether the wind blows or the sun shines. But it is us humans who decide when we need energy and what type.
- What if the wind does not blow or the sun does not shine or if it blows more than we need?
- How do we cope with a lack or an excess of produced electricity?
We need technologies that produce electricity from other sources than wind or sun and that store electricity for later use.
Fuel cells and electrolysis are two technologies that can do just that. The following pages give you a basic insight in those technologies with a special focus on high temperature fuel cells and electrolysis.
