Introduction to Green Hydrogen and Green Ammonia

Abstract

The transition towards a sustainable and decarbonized energy landscape has propelled the exploration and utilization of green hydrogen and green ammonia as key enablers of a cleaner future. This chapter examines the latest advancements, challenges, and opportunities surrounding the production, utilization, and potential impact of green hydrogen and green ammonia on global energy systems and sustainability goals. The global shift towards renewable energy sources has underscored the importance of green hydrogen and green ammonia in reducing carbon emissions and fostering energy independence. As countries worldwide strive to meet their climate targets and embrace cleaner energy alternatives, the role of green hydrogen and green ammonia in facilitating the transition to a low-carbon economy has gained significant traction. One of the primary focuses of this chapter is to elucidate the various production methods of green hydrogen, with a particular emphasis on electrolysis processes powered by renewable energy sources, which offer a viable alternative to traditional fossil fuel-based hydrogen production techniques. The chapter explores the technological advancements and innovations driving the scalability and cost-effectiveness of green hydrogen production, paving the way for its widespread adoption across diverse sectors. It also investigates the pivotal role of green ammonia as a carrier of renewable energy, highlighting its potential applications in energy storage, transportation, and industrial processes. The versatility of green ammonia as a carbon-free fuel and chemical feedstock underscores its significance in enabling a circular economy and reducing greenhouse gas emissions. In addition to discussing the production and utilization aspects, this chapter also addresses the infrastructure requirements and challenges.
