3. Hydrogen – Situation in Belgium
Only 3 hydrogen refueling stations and 23 H2 vehicles
so far.
Industrial feedstock demand mainly in refineries &
ammonia plants
Captive plants, merchant plants and as byproducts
Predominantly produced by steam methane reforming

4. Introduction to the study
Evaluate the potential of power to hydrogen (H2
from low carbon grid electricity) in Belgium.
More focus on supply side – production of H2 using
electrolysis.
Centralised or Onsite Production? How much
capacity required? How much investment?
Water electrolysis – Alkaline or PEM electrolysis?
Electrolysis or steam methane reforming for
industries?

9. Hydrogen Demand (Exogenous Input)
• Transportation: The number of FCEV cars in 2050 is approx. 20 % of
the total number of vehicles.
• Industries: demand estimated based on existing demand (0.4
Milliontonne) considered based on various studies.

15. Results – Transportation Sector
• Decentralised production
with alkaline electrolyser
dominates the hydrogen
production.
• However, share of centralised
mode increases as the
electricity mix gets
decarbonized and hydrogen
demand increases in long
term.

16. Investment Required for Hydrogen Refuelling
Infrastructure - Transportation Sector
16
Around 2.5 GW electrolyser
capacity required by 2050
This will incur around 5.5 billion
euro investments required

19. Results related to industrial sector
• In industry sector – Alkaline electrolysers started to be
competitive with steam methane reforming from 2040.
• Onsite production was found to be the least cost option.
• Centralised mode may not have been preferred because the
industrial H2 demand profile was kept constant.
• Approximately, cumulative emission reduction of 15 million ton
of CO2 in both the scenarios.

22. A note on comparison b/w Alkaline & PEM
electrolysers
• Partial load characteristics were modelled using TIMES extension for
dispatching & unit commitment.
• PEM electrolysers were never found to be competitive with alkaline
electrolysers.
• Cannot draw conclusion based on this result as the model always
made the electrolysers work without any partial load efficiency drop.
• A MILP approach would be required to compare the alkaline & PEM
electrolysers.

23. Conclusion
Although grid connected electrolysers increases the emissions in early
years, this has a potential to reduce emissions in the long term when the
electricity mix is highly decarbonized
Centralised mode of production becomes relevant when there is large H2
demand and when there is large share of renewables.
Power to hydrogen can help more renewables penetration.
However, Belgium should accelerate decarbonizing its electricity mix.
Import of green H2 , alternative H2 production like green H2 production
from off-grid electrolysers, blue production from SMR (with CCUS) and
pyrolysis should also be explored
