Glossary

Base load

Base load, peak load and medium load play an important role in power generation. What is the base load? Base load refers to the amount of electricity – or electrical power – generated that is needed during the course of the day. The terms medium and peak load, on the other hand, refer to the power that is produced in addition to this, but is not needed all the time.

Double benefit through combined heat and power generation

Fuel cells play a pivotal role in energy supply. They are the key technology for converting a fuel, whether hydrogen or methanol, back into electricity. In this way, energy is made transportable on the one hand and available on a decentralized basis on the other. The whole thing works powerfully, efficiently and in an environmentally friendly manner.

Electricity from renewable energies

Electricity from renewable energies has long since accounted for a large share of the power supply in Germany. As part of the energy transition, suppliers of electricity from renewables are further expanding climate-compatible "green power". The aim is to generate electricity and heat only from renewables – also to make us less dependent on imports of fossil fuels.

Fuel cell efficiency

Successful implementation of the energy transition requires more than just electricity from renewable sources. Sustainable power generators, smart grids and flexible electricity storage systems are equally important for success. Efficiency is an important factor in the interaction of all components. But how can a statement be made about what is efficient and what is not? And how can the efficiency of individual power generation technologies be measured and quantified? The efficiency factor provides information on this. What do you mean by efficiency? The efficiency factor provides information on this.

Gas grid

The gas grid in Germany ensures that the natural gas extracted at the respective production sites reaches the end user. The article explains the system of gas supply in Germany, where our gas comes from and what the gas grid of the future might look like. In particular, it looks at the importance of hydrogen for the gas network.

Oxygen as oxidizing agent

Oxidation, reduction. We’ve heard this before, but it’s been a long time. What is it all about again? What is an oxidant? And what does all this have to do with fuel cell technology? A lot, because neither an EFOY Jupiter hydrogen fuel cell nor an EFOY direct methanol fuel cell can work without an oxidizer. To start with, let’s explain the difference: oxidation is a chemical reaction involving oxygen. Reduction is a deoxygenation reaction.

Primary energy is not secondary

The best energy is that which is not consumed in the first place. Logical, all critics of common bon mots may now object. But how is that supposed to work in a globalized world and an increasingly digital economy? Industry needs energy, cars need fuel and the home needs to be heated. You may be reading this text right now on the screen of your PC. As you can see, reducing energy consumption is one thing.

Reducing agents

Reducing agents are also called reducers and are substances that donate electrons and in this way reduce other substances. In this process, the reducing agents themselves become oxidized.

Secondary energy has many facets

If there is primary energy, there must also be secondary energy. The prefix alone suggests this. The following text will deal with secondary energy. What is secondary energy? It is best to start directly with a definition of secondary energy. Secondary energy includes the types of energy that do not come directly from nature. So, in that sense, it is converted primary energy. Primary energy includes lignite, petroleum, and natural gas, but also solar energy, wind power, hydroelectric power, geothermal power, and tidal energy.
