International cooperation will be key to unlocking the competitive production of green hydrogen as global trade will be required to link those countries, such as South Africa, that are best suited to producing the energy carrier, using a combination of low-cost renewable energy, water and electrolysis, with the main consuming markets in Asia and Europe. In fact, the secretary-general of the German branch of World Energy Council (WEC), Dr Carsten Rolle, says that all of the nine countries that have already developed national hydrogen strategies make explicit mention of the need for international cooperation and trade to support the development of green-hydrogen projects.
