The "Hydrogen Economy" is very broad subject ranging from the potential use of hydrogen for domestic use to the mass production of hydrogen replacing coal, natural gas (LNG) and conventional transport fuels.For any given project, there are many alternatives to consider for each stage of making, storing and transporting hydrogen. The book aims to assist proponents, and financiers of hydrogen projects to identify the optimum alternatives and identify hurdles and approaches to overcome them. This book attempts to describe an optimum approach to implement and its cost. It sets out to identify hurdles to implementation which may not be apparent to those entering the field for the first time.The book covers the various means and costs of production from fossil fuels (with carbon capture) - blue hydrogen - electrolysis - green hydrogen - or biomass. The book covers hydrogen storage as liquid or compressed gas and transport, through pipelines as liquid or by an intermediary fluid such as ammonia or a hydrocarbon. The book also discusses the production and costs of hydrogen delivery at the user end of a logistics chain. It also compares the relative energy value of energy delivered hydrogen versus the current suite of conventional fuels.

Gives an overview of the technologies and economics in the production of olefins in the petrochemical industries. This compendium highlights the options and costs for producing olefins using different technologies and different feedstocks at a time when the cost of carbon dioxide emissions are set to be included in the production cost.
