The Energiewende requires storage capacity to ensure
1. Security of supply (seasonal storage)
2. Grid stability, mainly for mid & low-voltage grid

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
