Risk assessment when using hydrogen

02.07.2020

Hydrogen is an efficient and environmentally friendly energy carrier, and the use of hydrogen as an energy source is often considered as a zero-emission alternative. Hydrogen is a colourless, odourless gas, which by itself is harmless, but when the gas is pressurized, it poses a risk that must be managed. The use of hydrogen is not novel, even though hydrogen receives a lot of attention nowadays, including through strategic plans for the use of hydrogen established by e.g. the EU and the governments in the UK and Norway.

Hydrogen has been used on a large scale industrially, but in the later years, it has gained a wider use as an environmentally friendly energy source. This entails that the use of hydrogen will be closer to the public. When planning the use of energy sources such as hydrogen, the risk attached to the use of hydrogen and the conditions this sets for a project must be  assessed early in the process.

Safetec has recently conducted a risk assessment on behalf of Ørlandet municipality, related to the use of hydrogen as an environmental measure and mitigation in the urban development of Uthaug/Brekstad. The work intended to identify consideration zones according to the regulations implemented by the Norwegian Directorate for Civil Protection (DSB). This provides guidelines for restricted access areas around the various parts of the production and distribution plant, which is an essential part of the work to ensure that there is sufficient space available. The consideration zones are therefore an important premise for further design of the plant.

Are you interested in knowing more about how we can help with risk assessment related to hydrogen or other alternative sources of energy?
