How Ukraine can rebuild its energy system
Research
ETH Zurich
Researchers at ETH Zurich have been working with researchers from Ukraine and Germany to investigate how to rebuild Ukraine’s destroyed energy infrastructure based on renewable energy. They have determined that solar and wind energy would quickly deliver a distributed power supply system and prevent corruption.
Is air conditioning a threat to the power grid?
Research
EPFL
The elevated temperatures this summer prompted many of us to crank up the air conditioning. In Switzerland, the energy used for cooling is approaching that for heating. What does that mean for power grids?
Iron as an inexpensive storage medium for hydrogen
Research
ETH Zurich
Researchers at ETH Zurich are using iron to store hydrogen safely and for long periods. In the future, this technology could be used for seasonal energy storage.
Music at high voltage
Teaching
Empa
A Tesla coil that makes music besides flashes of lightning? No problem for Silvio Müller and Yanis Strüby, apprentice physics laboratory technicians at Empa. With their singing Tesla coil, they won both the jury and the participant award at the «Züri-Oberland» apprentice competition.
HVAC is starting to sweat
Research
Empa
Thanks to sensor technology and mathematical modeling, smart dummies provide new insights into how workplaces can be brought to a comfortable temperature in an energy-efficient way and how to prevent patients from getting cold feet in the operating theater.
Renewable energy puts power grids to the test
Research
EPFL
To transition away from fossil fuels and towards renewables – which are intermittent by nature – we’ll need to rework our entire system of power storage, transmission and distribution. Yet experts haven’t yet found the right energy mix or power storage system, or how to balance supply and demand effectively.
