Finland’s VTT brings BALANCE to renewable power
VTT Technical Research Centre of Finland is coordinating a European Commission-funded project which brings together several leading European research institutes in the field of electrochemical conversion.
The three-year 2.5 million-euro BALANCE project seeks to demonstrate a technology that enables flexible storage of large amounts of renewable power. This electrochemical conversion technology is known as ReSOC (Reversible Solid Oxide Cell).
Such technologies are needed for the further integration of additional wind and solar power, restoring the balance between their weather-dependent production and the general power consumption.
When green electricity is produced in copious amounts on a windy or sunny day, a ReSOC device enables power to be converted into a chemical, which can be stored for later use or used as industrial feedstock. Similarly, during peak consumption hours or on a calm, cloudy day, the stored chemical is converted back to electricity at the same site.
