What we do?

Hybrid Power Plants on Islands!

Cogeneration Power Plants with

efficiencies > 90%!

Climate-friendly power generation, based on Biomass.

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

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!

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

• 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.
