Hydrogen-based Energy Systems

Agenda

Module 1 - Context: Decarbonisation

This module seeks to explain the basis of decarbonisation and how hydrogen is relevant to it. The current status of data supporting anthropogenic CO₂ as the lead driver of climate change is discussed, as are the expected climate tipping points. Legislation regarding decarbonisation and the key policy support for hydrogen as a partial solution in the fight against climate change is explained.

Module 2 - Hydrogen Economy

This module explains the concept of the ‘Hydrogen economy’. It does this by discussing the current electrical network capacity, constraints and the impact of increasing renewables penetration upon it. The ‘Power to X’ concept is discussed to explain how renewable energy can be used to generate hydrogen or other derivatives of hydrogen such as liquid e-fuels and energy vectors. The concept of 'Sector coupling' is explained and examples of several current hydrogen clusters are provided. Finally, the process of project development, planning and consenting is summarised.

Module 3 - Hydrogen Market

This module explores the current global market for fossil hydrogen and the sectors that produce and consume it. In the context of decarbonisation, the projected demand required by new and emerging sectors is discussed to provide an understanding of the gap between hydrogen available and future hydrogen demand out to 2050. The forecast global market opportunity for both hydrogen and all the technologies, componentry and services. Finally, the factors relating to the unit cost of hydrogen or Levelised Cost of Hydrogen (LCOH) are described.

Module 4 - Physical Properties of Hydrogen

This module seeks to explain the physical properties of hydrogen compared to typical energy carriers (fuels) used today. The safety considerations associated with hydrogen in its various formats is also discussed including gaseous, liquid and derivatives and their associated hazards.

Module 5 - Production

This module explains the colour classification of hydrogen produced via various technical process routes. The impact of these routes in terms of carbon intensity and relative cleanliness of the resulting hydrogen is discussed in the context of decarbonisation. An introduction to each of the most common process routes for producing hydrogen is given including the various sub classes of electrolysis and reformation.

Module 6 - Consumption

This module revisits the sectors in which hydrogen is consumed today and the evolving mix of hydrogen users resulting from sector coupling and P2X segments as we move towards 2050. When used as a fuel directly, hydrogen can be burned or consumed electrochemically, hence hydrogen combustion and fuel cell technologies are introduced.

Module 7 - Infrastructure & Logistics

This module introduces the hydrogen value chain concept which describes the route that the hydrogen must take from producer to consumer, which may involve crossing oceans or being stored for several years before use. The various mechanisms by which hydrogen can be stored and transported at various scales, and technologies involved are discussed.
