In order to evaluate the financial feasibility of integrating energy storage systems with solar PV system in detached houses, economic indicators able to compare the costs of the different storage scenarios with one another are needed.
While the costs of all energy storage systems remain too high to be considered financially attractive without further support mechanisms, LIB storage is clearly the best storage alternative in all scenarios with a LCC 1000–7500 € higher and a LCOE 0.005–0.04 €/kWh higher than the costs of a 13.5 kW stand-alone solar PV system.
Hence, the optimal capacity of all the energy storage systems is zero, whereas the feasible solar PV size is limited to below 20 % when using the 2019 electricity prices as comparison.
For the battery storage system, a 90 % round-trip efficiency was used, representing the use of a generic LIB , . For the H 2 energy storage system, a 30 % round-trip efficiency was used, a value that could also be lower for small-scale energy storage applications.
Solar PV systems without selling surplus electricity to the grid were profitable up to a renewable fraction of 10 % with 2019 market prices and up to 35 % with the 2021 unusually high market prices.
While LIB storage clearly remains the most feasible energy storage technology with a LCOS of 3–5 times higher than the LCOE of grid electricity, the LCOS of the discharged energy from the H 2 storage and TES system is between 5 and 20 times higher than that of grid electricity.

Kryogene Energiespeicherung (Cryogenic Energy Storage/CES, auch Liquid Air Energy Storage/LAES) bezeichnet den Einsatz tiefkalter () Flüssigkeiten, wie beispielsweise flüssige Luft oder , als . Beide Kryogene werden bereits in Fahrzeugantrieben genutzt. Der Erfinder Peter Dearman entwickelte ursprünglich ein mit flüssiger Luft betriebenes Fahrzeug, nutzte diese Technologie dann aber auch für einen Netzenergiespei. [pdf]
Ein 1600 m3 Flüssiglufttank kann etwa 220 MWh elektrische Energie speichern. Zusammen mit einem Technologiepartner haben wir ein System mit 80 MW Leistungsabgabe entwickelt, das auf verfügbaren Komponenten basiert und bereit zur Demonstration ist. Gleichzeitig arbeiten wir an der nächsten Generation von Systemen mit verbesserter Performance.
Ein neuer Stromspeicher auf Basis flüssiger Luft soll die Versorgungssicherheit bei Nutzung erneuerbarer Energien garantieren. München (Deutschland). Erneuerbare Energien wie Solar-, Wind- und Wasserkraft können zwar CO2-neutral Strom produzieren, unterliegen in ihrer Leistung aber einer hohen Volatilität.
Es nutzt flüssige Luft, den Energiespeicher und Abwärme, um die thermische Reexpansion der Luft zu verstärken. Aus der flüssigen Luft wurden Kohlenstoffdioxid und Wasser entfernt, da diese bei der Speichertemperatur gefrieren würden. Der Wirkungsgrad beträgt zurzeit weniger als 15 Prozent.
Flüssige Luft beansprucht nur noch ein Tausendstel des ursprünglichen Volumens und lässt sich über lange Zeit in einem großen Vakuumgefäß bei Atmosphärendruck lagern. Bei hohem Strombedarf wird flüssige Luft mit hohem Druck in einen Wärmetauscher gepumpt, der als Heizkessel dient.
