Methodology
• A 100% renewable energy system for Europe
• System built cross-sector integration
• Large amounts of DH and HP
• Makes use of waste heat
• Includes high electrification level in all sectors
• H2 is used in PtX for transport sector
• System uses sustainable amounts of biomass
• Hydrogen replaces other renewable fuels in
each energy sector
• Only green H2 is used
• New H2 related infrastructure costs included
• Offshore wind capacity is used as variable to
balance the hydrogen demand
• Same system boundaries are kept as in the
reference (no energy imports, limited electricity
exports, 40-50% full-load hours electrolysis)

hydrogen utilization

Conclusions
Cost of saved biomass in best case scenario for
each energy sector
Hydrogen – the molecule of the future?
• No. The electron is more suited to be the energy vector of
the future.
• Direct hydrogen increases system costs in all scenarios
• Hydrogen transmission cost share is minimal, but
distribution and fueling installations are expensive
• Can be a tool to reduce pressure on biomass consumption
in specific cases, but so can electromethane
• Hydrogen is unpractical
• Despite being less energy-efficient, liquid and gaseous
electrofuels may be more practical
