HYDROGEN HANDLING


Neptune participates in Nexstep’s Reuse & Re-Purpose working group and since several years in TNO’s North Sea Energy Program. The H2 pilot was the result of staying tuned in these initiatives.

Neptune is still looking for partners in the pilot. Exploring meetings have been held with electrolysermanufacturers, Distributions System Operator Stedin and nearby windfarm operator Eneco.

Way forward:

• Budget approval from Q13-A partners (TAQA; EBN; Neptune)

• P15-C/D operator to join (TAQA)

• Request for subsidy; being done by TNO and Nexstep

• Get pilot partners on board to supply electricity and PEM electrolyser

16

STATUS AND WAY FORWARD


Neptune Costs (+/- 30% accuracy):

2 mln eur for pre-study (Legal, Safety, Permitting, Operational, HR etc etc)

2.5 mln eur for platform modifications

Neptune receives 25% subsidy for the above amount

Not included:

PEM electrolyser and sea water treatment system ( to be purchased by TNO, who recieves80% subsidy) 2-2.5 mln eur

Electricy supply and transport 0.5 – 1 mln eur (trying to get Stedin and Eneco on board)

Modifications needed on host platform P15-C/D (TAQA to estimate and get subsidy andpartner approval)

17

COSTS


Subsidy request finalised and all partners on board: Q1 2020

Budget approval for pre study work appr 2 mln Q1 2020

FEED and scope definition finalised Summer 2020

FID and start purchasing Long lead items (electrolyser) Q3 2020

Delivery electrolyser and Q13-A platform modifications ready: Summer 2021

Onshore electrolyzer tests ready (3 months) Q3 2021

Offshore installation and commissioning ready Q4 2021

Start up Q4 2021

Duration pilot (2 years)+ removal containerised units End 2023

TIMELINE


Short term

• H2 will be used as fuelgas on TAQA’s P15

• H2 Production: 200 Nm³/hr => 0,5 mln Nm³/y Natural gas equivalent

• H2 content in fuel gas is less than 10%; which is OK according to Solar Turbines

• 1,000 t/y abated CO2

Longer term

• Windpower far from shore can be evacuated via existing gas infrastructure to shore, and beyond

• H2 can carry part of the cost operational cost and enable tail end offshore domestic gas production

19

THE BENEFITS


• Windpower to be routed further inland:

• “IJmuiden Ver” with 2 x 2 GW DC cables potentially to Geertruidenberg

• “Ten Noorden van de Waddeneilanden” potentially crossing the Waddenzee to Friesland

• High cost and long term permitting

20

WINDFARMS BEYOND 2023; ROADMAP TENNET


• Hydrogen commingled with Natural gas to shore

• Can the conventional steam reforming process maintain the economic value of H2?

21

WINDFARMS BEYOND 2023: HYDROGEN ROUTE


• Vattenvall and Equinor: Magnum powerplant run on “Blue Hydrogen”

• Gasunie started up HyStock in summer 2019

• NAM intends to convert their “Gaszuiveringsinstallatie” in Emmen

22



• Hydrogen form the Doggersbank to NL and UK via existing infrastructure

• 36” NGT pipeline has 8-12 GW H2 capacity.

• Pipeline technical capable of handling 100% H2

23



• Constrains in the electric grid can be solved by the gas infrastructure.

- Windfarms are being built further from shore

- Fluctuating renewable power can be handled by the gas infrastructure.

- Capacity of the 36” pipelines are about 10x higher than the biggest HV DC cables

- Comingled stream of H2 and natural gas is possible

- H2 extraction might be possible by conventional Steam reforming (Under investigation)

24

OFFSHORE HYDROGEN LONG TERM – THE BENEFITS


Sharing infrastructure and costs

- Accelerate the energy transition

- No renewable energy goes to waste

- Enables long term North Sea offshore gas production

- Fossil fuel with the lowest carbon footprint

- Domestic offshore gas has a lower footprint than imported gas

- Domestic gas/energy supply has socio/economic benefits

- Safest conditions / stict permiting and supervision
