AbstractDecarbonization and energy transition will have a large impact on how our mobility, as well as supply of materials for clothing, building, and construction, and even for food, will be energized and processed. This review will give a brief survey of a few main changes and what they mean for process safety. It concerns hazards of hydrogen production and handling, battery systems, and electrification of the process industry, which will bring a range of changes, some easy, others intricate. Coincidentally, three recent papers in the journal Ergonomics prove to be in line with these process safety challenges.
