 Have you ever wondered how our energy system of the future will look like? Which technologies will be used to generate and transport energy? How will we consume energy? And most importantly, which synergies among energy technologies can we exploit to our advantage? How do we technically achieve this? We address these questions in our course and invite you on this journey with us. In this introductory course, you will learn about upcoming energy technologies focusing on their compatibility and integration. We will cover renewable energy generation, storage and consumption in the thermal, electric and gas sectors. We will look at electric transportation and its interplay with the energy system, considering how an electric vehicle can be an energy storage for the grid. Furthermore, we will consider how to intelligently control and convert energy from one form to another at the system scale. In this course, you will learn how to design the energy system of the future while exploiting the synergies among technologies and energy carriers. This knowledge will put you in the centre of the energy transition as a skilled energy system designer. So join us in designing our sustainable future.
