Market study nexus water-hydrogen South African contribution The GH2 combi track aims to catalyze the development of green hydrogen economies in SA and NAM. On Green Hydrogen several studies have been executed, including on Dutch propositions for South Africa and Namibia. For both propositions, the water-green hydrogen nexus are identified as areas for cooperation. This study is a follow-up of this identification.The water needed for green hydrogen production cannot come from fresh water sources. These sources are already under pressure and needed for domestic consumption, agriculture and industrial use, as well as for keeping ecosystems healthy. Therefore there is a need to look at other water sources for green hydrogen production. Options to further explore are desalination of seawater, the use of water from waste water treatments, or the purification of acid mine water.There is currently a lack of information about the benefits and costs of these three options, where potential projects can be developed to produce water from these sources that can be used for green hydrogen production, and Dutch technology, innovation and interest that can be matched to opportunities in SA and NAM.The three objectives this proposed project relates are:•	Position the Netherlands as significant partner in the move towards that economy and ecosystem, creating opportunity for Dutch business and innovations in the whole value chain, while making progress on development, sustainability and climate agenda •	Partner with South Africa and Namibia to address their challenges and boost implementation of their plans on GH2•	Build and boost skills development initiatives with Dutch knowledge and technology
