Energetics is one of the main directions of future development of chemical engineering, in which many jobs positions are available and many new applications are created. The goal of the class is to broaden horizons of the students in the area of current social problems because these topics are not dealt with in any other courses offered in the department. Another goal is the introduction of successful and unsuccessful engineering solutions or innovations of specific products with high added value. Most of the concepts are analyzed from the perspective of their competitiveness and further economic or other benefits.
Aim of the course -
Last update: Lindner Jiří Ing. Ph.D. (14.06.2019)

The students will gain theoretical and practical skills for:

1. Classical and renewable sources of energy and technology of their utilization (fotovoltaics, heat pumps, biofuels,…)

2. Technology for electrical and other energy storage (electrochemical, conversion technologies,…)

3. Energy savings (e. g. passive houses).

4. Rational chemical-engineering view of energetics.

5. Utilization of so called enabling technologies and smart technologies.
