The Energiewende requires storage capacity to ensure

1. Security of supply (seasonal storage)

2. Grid stability, mainly for mid & low-voltage grid

Energiewende: technical & commercial requirements

4/16/2014 Slide 11 CCUS Conference Columbia 04/14/ sunfire GmbH

PtX storage for the Energiewende

1. is mainly required in the mid & low voltage grids

=> 30 – 500 kW units (current best guess to be confirmend)

2. hardly operates beyond 2000 hrs/a in storage mode (low cap. ut.)

=> high capex/kWhstorage

=> regulative incentives (supercredits) are not sustainable (risk)

=> no commercial investment

What does a commercially attractive storage business model look like?

Increase Capacity Utilization by Inclusion of Power-Supply for storage downtimes

rSOC/PtXtP in one unit

Energiewende: technical & commercial requirements

The concept of reversible Solid Oxide Cell (rSOC)

4/16/2014 Slide 12 CCUS Conference Columbia 04/14/ sunfire GmbH

Driven by the need for grid stability and high capacity utilization, PtX-units must be reversible to supply during energy shortage (XtP)

Grid connection allows flexible capacity share between storage & supply;

(other than batteries, compressed air etc.) => operation according to currently best revenues

PtX can supply other marktes (e.g. biofuel certificates) than XtP => extra revenues

PtX can produce high quality fuel, XtP can use low quality fuel=> cost/rev. optimisation

Various degrees of freedom reduce regulative risk for investors

decentral/lateral power storage & supply is strategic for the Energiewende

Let´s make it real…

…and thanks for your attention!
