CURRENT STATUS NATURAL GAS IN NL
452 gas fields discovered (on- & offshore)
• 265 in production
• 4 converted to gas storage
• 62 depleted
• 30 planned for production
• 77 “stranded fields”
• 148 platforms on the Northsea
Infrastructure (platforms and pipelines) are
at maximum and will decline from now on!
Decommissioning has started in the North Sea
Current reserves: 1090 BCM (25 jr)
Of which ~779 BCM still in Groningen
Onshore: 144 bcm
Offshore: 167 bcm
OFFSHORE PIPELINE GRID
~4000 km pipelines
4 major trunklines (WGT, NGT, Local, Nogat)
4 gas treatment facilities (Den Helder, Uithuizen)
Full capacity not used anymore and in decline
NOGAT trunckline up to the Doggers bank area
Nearby future wind parks in central North Sea
Future of pipeline grid is uncertain (OSPAR)
Several sections of the offshore grid will become obsolete soon
Potential for re-use (CO2, H2)?

FUTURE GAS PRODUCTION FROM SMALL FIELDS
Excluding Groningen field
The Netherlands will
become import dependent
Offshore production
until 2040

outliers
Offshore Production
will stop around 2050
THE INDUSTRY IS PREPARING FOR
DECOMMISSIONING
High societal cost (72% public share)
End of life (Economic or Technical)?
Eliminate options for re-use or re-purpose
Impact on ecology from removal?

System Integration in Offshore Energy
KEY SUCCESS FACTORS
FOR SYSTEM INTEGRATION
Can it be made economic?
Does it fit in space and time?
Is the technology mature?
Does the legislation allow it?
Are stakeholders aligned and committed?
Is there public acceptance?
Is there an environmental benefit?

CONCLUSION NORTHSEA ENERGYConnecting offshore windfarms and gas platforms can create a stable, affordable and clean energy
system in the Northsea
Electrification of platforms will reduce the emissions of NOx, CO2 and CH4 to zero
Conversion technology on platforms will create potential for grid stabilisation
Power to gas (H2, CH4)
Gas to Wire (with CCS)
Pipeline infrastructure can be used to transport energy at large distances (via H2 or in CH4)
Depleted gas fields can be used for energy storage and balancing (CAES, UGS, CO2)
Reuse of infrastructure will
Reduce the societal cost of offshore energy (decommissioning and power grid)
Maximise economic revenues of energy sources offshore with zero emission
Create employment and business opportunities for the offshore sector
