Namibia is pursuing the long-term goal of climate neutrality and strategically positioning itself to become a global leader in green hydrogen and its derivatives over the next decade. The nation aims to leverage green energy and green hydrogen as pivotal elements to attract foreign investment, enhance energy security, and support a just energy transition. The Government is committed to using green hydrogen to significantly decarbonize its economy, while creating local employment opportunities. In 2021, the Namibian and German Governments signed a bilateral agreement through a Joint Communique of Intent (JCOI) to provide funding worth of 40 million Euros for these initiatives. So far, the Namibian Government developed various initiatives on green hydrogen, including the Namibia Green Hydrogen and Derivatives Strategy, pilot plant projects, capacity building, promotion of a rapid market, and establishment of a value chain from demand to supply (both nationally and internationally). The Southern African Science Service Centre for Climate Change and Adaptive Land Management (SASSCAL) is appointed as the implementer for the JCOI and now plays a central role in coordinating and monitoring the implementation of the JCOI initiatives. Before the JCOI, SASSCAL was the lead implementer of the H2 Atlas project for Southern Africa, which was the first joint initiative with the German Federal Ministry of Research, Technology and Space (BMFTR). The H2 Atlas project explored the potential of green hydrogen production from abundant renewable energy resources in the region. This paper presents the overall progress and milestones on green hydrogen developments in Namibia under SASSCAL. An H2 Atlas for Southern Africa was developed through the H2 Atlas project using data collected on green hydrogen value chain parameters (water resources, land eligibility constraints, energy demands, existing infrastructure, socio-economic and policy data, solar resources, climate data, amongst others) from twelve Southern African Development Community (SADC) African countries. JCOI initiatives that are now commenced are the: Implementation of the Namibia Green Hydrogen and Derivatives Strategy, which is being spearheaded by the Government-established project management unit, the Namibia Green Hydrogen Programme. Initiatives under active SASSCAL implementation are the two (2) pilot projects, namely, Daures Green Hydrogen Village (DGHV), the Cleanergy Green Hydrogen Plant and Refueling Station (Cleanergy) as well as the capacity building Youth for Green Hydrogen Scholarship Programme (Y4H2). The DGHV aims to establish a self-sustaining energy ecosystem, producing green hydrogen and green ammonia, the production of agricultural products, a training facility in the hydrogen and agricultural space and the enablement of research activities related to green hydrogen and green ammonia industries. Cleanergy is designed to produce green hydrogen and for the creation of infrastructure for hydrogen-powered mobility appliances, as well as to provide green hydrogen-related training on operational safety, health, environment, and material standards at their established H2 Academy on site. The Y4H2 Scholarship programme provides green hydrogen-related sponsorship for capacity building for skills development at Master’s and Technical and Vocational Education Training (TVET) levels. The significant progress and milestones achieved illustrate how Namibia is moving from concept to implementation of its green hydrogen development roadmap. The initiatives have further contributed to partnerships and underscore the importance of embedding research, skills development, training, and sustainability into every stage of implementation.
