Techno-economic viability of decentralised solar photovoltaic-based green hydrogen production for sustainable energy transition in Ghana

Image
  I am delighted to share our published research paper with you. [Transition to a sustainable energy supply is essential for addressing the challenges of climate change and achieving a low-carbon future. Green hydrogen produced from solar photovoltaic (PV) systems presents a promising solution in Ghana, where energy demands are increasing rapidly. The levelized cost of hydrogen (LCOH) is considered a critical metric to evaluate hydrogen production techniques, cost competitiveness, and economic viability. This study presents a comprehensive analysis of LCOH from solar PV systems. The study results indicate that the LCOH is about $9.49/kg, which is comparable to other findings obtained within the Sub-Saharan Africa region. The study also forecasted that the LCOH for solar PV-based hydrogen produced will decrease to $5–6.5/kg by 2030 and $2–2.5/kg by 2050 or lower, making it competitive with fossil fuel-based hydrogen. The findings of this study highlight the potential of green hydrog...

Transition to Green Hydrogen Economy

  GH2 Transition The adoption of green hydrogen represents a profound shift with far-reaching implications for energy, water, and food security. Simultaneously, careful consideration must be given to the potential effects on land use, ecosystems, and biodiversity. The central challenge lies in mitigating adverse externalities while ensuring that the positive outcomes and financial gains resulting from the widespread adoption of green hydrogen are equitably distributed throughout the entire country and continent. In formulating policy measures and road maps for the development of a green hydrogen economy, adherence to the principles of a just transition is paramount for sustainability and long-term success. African countries, in particular, grapple with a multitude of challenges in fulfilling basic needs for their citizens, encompassing access to electricity, clean water, decent employment, clean urban air, and education. In the implementation of large-scale green hydrogen produ...

Green Hydrogen as Sustainable Fuel or Energy Carrier

  Green Hydrogen as Sustainable Fuel or Energy Carrier Global for Decarbonization Introduction:  Over the last decade, green hydrogen has gained substantial interest as a versatile and potentially transformative energy carrier that can be used in various applications. It can be utilized as a fuel for transportation, stored as an energy source, and used as a feedstock for industrial processes. As the world strives to reduce greenhouse gas emissions and transition to a low-carbon economy, green hydrogen is seen as a key component in achieving sustainable and decarbonized energy systems. Here's a brief overview of how green hydrogen can contribute to this ambitious goal: Renewable Energy Storage: Green hydrogen can serve as a means of storing excess renewable energy generated from sources like wind and solar power. The intermittent nature of renewable energy can be mitigated by converting surplus energy into hydrogen through electrolysis. This stored hydrogen can later be ...

Water Electrolysis

Image
  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...

Green Hydrogen Levelized cost

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.

The future energy

 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
