Study into large-scale potential to store renewable hydrogen

Power fluctuations sometimes associated with renewable energy resources could become a thing of the past through research under way at the North-West University (NWU) on new and better ways to store hydrogen.

The HySA Centre of Competence (Coc) at the NWU explains the storage problem as follows:

Electrical energy produced from renewable energy sources such as wind and solar is used to generate hydrogen through the process known as water electrolysis.

Oyster mushrooms could make brown seaweed rich pickings for indigenous chickens

Brown seaweed is known to be a rich source of minerals such as calcium, manganese, potassium, sodium, phosphorus, sulphur and iron. Add oyster mushrooms to the mix and the result could be a highly nutritious source of feed for indigenous chickens.

This is the thinking of Godfrey Mhlongo, North-West University (NWU) PhD student in animal health, whose PhD thesis is titled “Towards the optimisation of brown seaweed (Ecklonia maxima) for indigenous chickens using oyster mushrooms”.

Wasps zoom in on metal contamination

Wasps are often viewed as pests but they can play a huge role in the ecosystem, from pollination to being a link in the food chain. North-West University (NWU) master’s student Yasfir Tarif Nadat is now undertaking a study to show how wasps can be indicators of pollution.

His study is inspired by a paper he and a team of researchers from the NWU, Linköping University and the University of Zimbabwe worked on. The team included Prof Henrik Kylin, Dr Rudo Sithole, Velesia Lesch and the NWU’s Prof Henk Bouwman.
