Triple-mode grid-balancing plants based on biomass gasification and
reversible solid-oxide cell stack: concept and performance

A paper in the scope of the W2W has been accepted by Applied Energy. It investigates the thermodynamic performance of the gasification based reversible solid-oxide stack system with power-to-methane capability, thus capable of providing grid-balancing services. It shows that the plant could reach high efficiency at all three modes of power generation, power storage and power neutral: up to 50–60% for the power generation mode, 72–76% for the power storage mode and 47–55% for the power neutral mode.

Reversible solid-oxide cell stack based power-to-x-to-power systems:
Comparison of thermodynamic performance

A paper in the scope of W2W has been published in Applied Energy, which investigates the thermodynamic performances of reversible solid-oxide stack based power-to-x-to-power systems with a systematic optimization based evaluation method. It finds that the rank of round-trip efficiency: methane (47.5%) >syngas (43.3%) ≈ hydrogen (42.6%) > methanol (40.7%) > ammonia (38.6%). The pool of plant designs obtained lays the basis for the optimal deployment of this balancing technology for specific applications.
