What we do?
Hybrid Power Plants on Islands!
Cogeneration Power Plants with
efficiencies > 90%!
Climate-friendly power generation, based on Biomass.
October 08, 2018 Page 4
The Challenge of Isolated Island Grids
High Volatility, due to• seasonal climate• tourism
High energy costs (€/kWh)
High dependency on imported fuels
High Environmental Impact
Lack of Interconnections to main grid
No central grid on the island –
decentralized energy solutions needed
„The solution must be based on renewables,but needs to ensure reliable power“
Lessons Learned from Pellworm and El Hierro

2 islands trying to switch to 100% Wind & PV (vRES)
Pellworm (Germany) El Hierro (Canary Islands)
First steps:
Lessons Learned from Pellworm and El Hierro
The Challenges
In both cases a 100% availability and 100% security of supply based on vRES and storage alone, cannot be ensured!

Step 1 Step 2 Step 3 Step 4
The way to 100% RES-Power
Increase share of e.g. wind & PV.
But, keep in mind volatility and security of supply on islands!
Add storage solutions!
Battery, Thermal storage & Power-To-X for longer terms.
Add reliable, efficient and dispatchable generation!
Running on Syn-Gas, Biogas or Bio-Liquids.
Leverage the advantages of each technology, by combining it to a Microgrid/VPP*!
Engine Power Plants as Enabler for more PV and Wind!

Benefits of Hybrid Power Systems

Combining engines with variable Renewable
Energy (vRES) and storage
• Ensures dispatchable and reliable power
also for long periods of no wind and sun
• Massive reduction of CO2-emission
• Fuel flexibility: Use of as much synthetic
gas as available – but fallback solutions like
LNG or biogas
• High efficiency via cogeneration
applications (power/heat/cold)
• Securing availability & grid stability by
using battery energy storage (BESS) for
operating reserve, frequency control and
supporting the engine dynamics
Reliable Energy with green footprint
• Bonaire, former Netherland Antilles (2011)
• 14MW Wind Power, 14MW Engine Power
• 300kW / 100 kWh Battery Storage
• Wykes, UK (2017)
• 6MW & 10MW (CHP) Application
• Running on Biogas
• Curacao, former Netherland Antilles (2018)
• 39MW, i.e. four dual-fuel engines to switch to LNG
• Back-up for wind & solar
• Virgin Islands, USA (2018)
• 21MW, i.e. three LPG engines (propane)
• Baseload, peaking and balancing power
• Public Utility Haßfurt, Germany (2018)
• 250kW (CHP) Application
• Running on 100% Hydrogen

The 5 Take-Aways
October 08, 2018 Page 10
Conclusion
• 100% vRES-only (Wind & PV) generation requires extremely high additional investments
• Combination of reliable thermal power & vRES & storage: the best solution
• Investments in gas-powered engines are no-regret options: they provide the necessary backup
and will operate with synthetic fuels
• Using renewable-based synthetic fuels as long-term storage is the perfect addition
• Co/trigeneration plants: the most efficient energy generation technology - heat & cold
Recommendations:
➢ Final trialogue negotiations on “Electricity market design”: • Support free markets to develop RES & flexibility options like engines (instead of capacity mech.)
• Level playing field for flexibility options – i.e. grid operators should buy flexibility through markets
➢ Vote on “Specific programme implementing Horizon Europe” (Ehler Report): • Support amendment 1377 to further adapt conventional thermal power generation to renewable fuels
(hydrogen, biogas, synthetic natural gas, sustainable biomass, etc.)
• Support amendment 1510 to develop hydrogen production and applications in a non-discriminatory basis, i.e.
not exclusively for fuel cells but also for e.g. reliable gas engines.
