Obviously, it’s the southward roof that delivers most of the electrical energy for the house, while on the West façade two solar panels capture the late afternoon and evening sun, producing roughly 2.0 kWp

Bring together a couple of energy nerds and the subject will soon change from trivial matters to how to save the world. As we get in, we praise the weather and converse on the flexibility of the digital city parking system and when driving the conversation quickly changes to the pros and cons of hydrogen versus methanol as energy carriers. Being an electrical- and telecommunications engineer he probably would be able to fix most of them.Īfter a short stroll from the station, we arrive at the parking lot, where his white electric Renault Zoe is parked. If he was to repair my home-appliances I would feel the enterprise was in safe hands with him. He is a gently looking man with lively blue eyes and a trusting appearance. Soon the all-electric train hits it’s cruising speed of 200 kmh and only 1 hour and 45 minutes later I get off in Göteborg (Gothenburg) where Hans-Olof waits for me. I board the X2000 train at Helsingborg Central Station in Sweden on a chilly but brilliantly clear spring morning.

It’s 9 AM and I just left the Scand Lines ferry arriving from Elsinore in Denmark (the hometown of Shakespeare’s Hamlet). On a cool, clear and sunny day, he kindly granted me a visit to his astonishing +500 square meter villa, 10 kilometers out of Gothenburg. Hans-Olof Nilsson is a Swedish engineer from the refrigeration industry who may be a retiree by age but in no way so by virtue – instead he decided to go off-grid with his house in a serious way, storing the summer sun as hydrogen to keep warm in the cold Swedish winter.
