A while ago we thought it was no longer needed within TU Delft: a group entirely dedicated to maintaining and developing the use of high voltage. After all, the expectation was that the grid would become decentralised in the Netherlands, and that households would start generating their own electricity. This has partly become true, however, a vast amount of the renewable energy comes in large ‘chunks’, for example through offshore wind farms and large solar fields. "The fact is that we need high-voltage more than ever," Prof Peter Vaessen emphasizes. "This is also the reason we have a new, revived high-voltage group at TU Delft: the High Voltage Technologies Group."

Nine young researchers compete for the best climate action & energy paper of 2023

Delft researchers are developing batteries that can charge faster, offer more stable storage and are made from sustainable materials that are widely available. In doing so, they offer a cheaper alternative to lithium-ion batteries that consist of rare materials and have a high CO2 footprint.
