5.3 Case Studies for Determining the Potential of Renewable Hydrogen …

• The Available R E Generation is the renewable electricity generation in TWh
available in the study case. The Available R E Generation is calculated
following three scenarios defined end of section 5.3.1.
• The Required R E Generation f or H 2R E production is the electricity generation in TWh calculated to produce the renewable hydrogen required for
decarbonising the industry sectors covered by the research work.
The decarbonisation potential is assessed against the study cases renewable energy
targets and their respective renewable energy potential.
When estimating the decarbonisation potential against the 2030 targets and the
technical potential renewable energy capacities, the hydrogen demand is adjusted
to the projected demand in 2030 [Table 5.14]. The steel manufacturing options
(a) and (b) are however not amended. A gradual replacement of the BF-BOF steel
manufacturing process by the DRI-EAF is expected over the coming decades. The
option (b) corresponds to a scenario where all steel manufacturing is done using
the DRI-EAF process.

Summary of chapter 5
The chapter 5 has answered the secondary question:
What is the hydrogen demand of industry sectors using fossil fuel-based
hydrogen as feedstock?
The chapter 5 has supplemented the chapter 4 by answering the
secondary question from a quantitative point of view.
The survey of the study cases has allowed determining the quantity of
hydrogen required in the production processes of ammonia, methanol, steel,
and oil refining. It is then possible to estimate the amount of renewable
electricity required for the decarbonization of those production processes
with renewable hydrogen.
