The first open day will be held at the Billia Croo wave energy site, out to the west of Stromness, on 1 September, starting at 12:30 local time.
The visitors will be able to learn about Orkney’s waves and tides and the technology being developed to harness their energy, as well as meet some of the EMEC team, tour the site and see some of the environmental monitoring equipment.
The second open day will be held the day after, on 2 September at the Kirkwall Pier hydrogen fuel cell, starting at 11:00 local time.
EMEC will explain the process of producing hydrogen from renewable energy and how Orkney is becoming a focal point for green hydrogen developments and the varied uses of hydrogen for decarbonising heat, power and transport.
Admission to both events is free.
