** : DDoD : Daily Depth of Discharge in % of the battery capacity
*** : NiCd batteries do require topping up during their lifetime
Batteries in HPS are specifically designed for solar application (daily cycles)
Typical application ranges:

5. ► Bi-directional Hydrogen unit
 Solar to Hydrogen - in case of excess Solar Power
 Hydrogen to Electricity - in winter or long periods of fog
► Latest Technology
 Completely green, no diesel back-up required
 Less Solar panels required, smaller footprint utilization
 Less Batteries required, or improving battery lifetime
► Limited maintenance (once every 2 years or less)
 electro-chemical compression, no rotating parts
 1000 liter water tank is sufficient
► 300 bar H2 pressure
 800 l storage capacity
 533 kWh: 293 kWh electrical, plus thermal energy
► Hydrogen fuel cell specifications:
 Max 8 kW electrical power, >8 kW thermal power
► Proven technology? Currently 4 pilots running successfully

Latest Innovation: Hydrogen Storage Unit

6. ► Platforms in production (new, existing or late life assets)
 Up to 100% renewable energy, depending on power requirements and load profile
 Particularly suited for power minimised platforms
► Between end of production and final decommissioning
 100% renewable energy supply on platforms in ‘Lighthouse Mode’
• Cold Stack : navigational aids system + remote diagnostics
• Warm stack : navigational aids system + annulus pressure monitoring + remote diagnostics
► Platforms in their re-use stage, after plug & abandonment
 Hydrogen production by electrolysis of water, using renewable power,
e.g. generated by offshore wind farms
 CO2 injection in depleted fields

Use case: onshore gas wells
separator
Gas & water pumped
from coal layers
This set-up with 24/7 Operations is causing many issues:
 Whereas hydraulic and submersible pumps are reliable, the
combustion (car) engines cause many reliability issues
 Significant emissions (SOx NOx COx and particles)
▼ Worsened by poorly or not working catalytic converters
 Significant noise pollution
 Production losses
▼ Fuel consumption
▼ Sub-optimised production process
▼ Long outages caused by engine failures
 Maintenance intensive
▼ Expensive due to remote locations
▼ Increased safety exposure, also related to logistics due to remote nature
