Production method #1 Power-to-Liquids


slide 5

sunfire‘s Power-to-Liquids process consists of three components:SOEC (Solid Oxide Electrolysis Cell), RWGS-conversion and fuel synthesis

Production method #1 Power-to-Gas


slide 6

Methanation is a relatively simple process. The increased efficiency due to the SOEC is still applicable. However, the economical potential of SNG is lower than for synthetic liquid fuels due to the cheap and still long time available natural gas.

Power-to-Liquids Willingness-to-Pay vs. cost


slide 14

Willingness-to-Pay currently uncertain

Fourfold Quota

Fourfold Quota

Fossil Portion

F. P.

The willingness to pay for sunfire-fuels is clearly higher than 0.10 €/kWh(LHV). The reason is the obligatory addition of renewable fuels to fossil ones with respect to 2009/28/EG – as well as the intended fourfold crediting of PtX-fuels to this quota (see source at the bottom).

An enhanced Business Model for the “Energiewende”: PtL and PtG as economical Positive Control Reserve


The renewable electricity “production” should always exceed the demand for electricity. The deviation can then be balanced by e.g. PtL and PtG plants.

The volitional excess-electricity will be utilized for 4 – 5 €ct/kWh and converted to products with a sufficient willingness-to-pay (e.g. liquid renewable fuels, clean synthetic waxes, SNG for CHPs, etc.).

The money for current gas and oil imports is invested into an integrated, cross-sectional electricity storage market and hence the “Energiewende”.
