Energy carriers (LOHC)
The intermittent generation of renewable energies (e.g. solar and wind power) requires efficient storage and distribution systems of appropriate capacity. In this regard, Liquid Organic Hydrogen Carriers (LOHCs) are very promising vectors as they can be loaded with hydrogen produced using renewable energies. Physico-chemical properties of LOHC are very similar to diesel, therfore today’s infrastructure for liquid fuels can be used for their handling which greatly facilitats the step-wise transition from today’s fossil system to a cleaner renewable energy supply for both, stationary and mobile applications. There are many different LOHC systems under investigation for different application scenarios. We try to select such LOHC systems which in addition to an optimal technical performance have also the lowest possible hazard potential for humans and the environment. For this purpose we examine (eco)toxicological profiles and the biodegradability of libraries of potential LOHC.
We are brining our LOHC research to a new level! Contaminant Science Group joins SAFeCRAFT consortium to support safety assessment of LOHC in marine transport of energy. Want to know more about SAFeCRAFT project? Visit SAFeCRAFT webpage, follow us on LinkedIn!
