Green Hydrogen

  Green hydrogen is generated through the electrochemical dissociation of water into hydrogen and oxygen in a process known as electrolysis. This process requires pure water and direct current electricity, which can be supplied by either a DC power source or an AC power source after transformation. The output of the process is primarily gaseous hydrogen, with oxygen and waste heat produced as byproducts. These byproducts can be repurposed for external uses.  Several electrolysis technologies exist, including alkaline electrolysis and proton exchange membrane (PEM) electrolysis, which are currently the most mature low-temperature systems. Other emerging technologies include anion exchange membrane (AEM) and high-temperature solid oxide (SOEC) electrolysis, which are currently in prototype and demonstration phases, respectively.  The electrolysis process parameters and electrochemical reactions differ based on the chosen technology. Hydrogen production occurs in the electro...

Africa is blessed with enormous renewable resources that could propel the continent to its energy transition goals with green hydrogen as a critical energy carrier. However, t he  state of techno-economic viability of green hydrogen decentralized  production  in Africa remains in its early stages especially in S outh  S aharan  A frica. There are currently few  ongoing research exploring both the potential benefits and challenges of such systems. While the continent offers significant potential for the deployment of green hydrogen technology, significant investment in infrastructure and the development of local skills and knowledge is  essential  to  guarantee  the long-term sustainability of such systems.  

 I envision a future where hydrogen is a key player in the global energy transition. While cost and technological maturity are currently the major barriers , right policies, realistic country roadmaps, social acceptance and technology innovation can help build global clean energy industries through carbon free hydrogen from renewable sources. The green hydrogen economy needs tailored support/commitment from the government, investors, researchers and industry players and I am optimistic about its future. #energytransition #cleanenergy #greenhydrogen
