In perspective: 500 ton liquid hydrogen per day
• 820 MWHHV hydrogen energy flux
• 7 TWh per year of hydrogen energy output
• Decabonised fossil route (NG with CCS):• < 1 % of annual domestic natural gas production
• Green route (electricity as sole primary energy source):• > 1200 MW electric power• ≈ 10 TWhel annually (about 7 % of annual domestic
power generation)9

• Envisioned production volume: 500 tons per dayo Required volume for one 160 000 m3 ship loading every 3 weeks (16 calls annually)o Comparison, Snøhvit LNG plant: 60–70 calls per year
• Energy flux in the hydrogen product stream:o 5.8 kg/s * 142 MJHHV/kg ≈ 820 MWHHV
• Corresponds to about 7 TWh per year of energy output• Theoretical minimum storage volume: 160 000 m3. Sketch below indicates size of 5 aligned 40 000 m3

Summary
• Norway has a large potential for hydrogen export
• Mid-term: Low-emission hydrogen in the GW range could be made from natural gas with CCS
• Long-term: Increasing potential from renewable power
• Both sources can give very low net CO2 emissions
• Hydrogen from fossil and renewable sources can be exported through common infrastructure
• Hydrogen production and export from Norway may be an emerging option of interest for:
• valorisation of domestic energy resources
• realising new industrial-scale CO2 capture and storage projects
• contributing to reductions in global CO2 emissions within power, heating, transport and industries
• Let us find the optimal balance between the options available to obtain a quick, secure and affordabletransition
