THE NORTH SEA IS AN OLD ENERGY SOURCE

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)?

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
