What is it about?
Stored wood pellets tend to form off-gasses (most relevant carbon monoxide due to its toxification potential), to lead to oxygen depletion in sealed or air-tight compartments and also to show some tendency for self-heating. The links between off-gassing and oxygen depletion on the one hand and self-heating on the other hand are not fully explored yet and there exists a manifold of different methods to investigate and assess the specific phenomena. This work is a first major attempt to compare, assess and correlate the different methods to and with each other.

Why is it important?
Off-gassing and self-heating threatens life. To have simple but robust methods in hand to predict both would be major step to develop the necessary mitigation strategies and minimize the related risks.
Perspectives
This article was a joint effort of the leading European scientists active in the fields of off-gassing and self-heating of / from wood pellets. Our overall objective is to contribute with this work to the establishment of common European and worldwide standards that support and consequently give confidence to safety and reliability of the wood pellets supply and value chain.
