Advent’s Materials Have Longer Lifetime and are Lower Cost Than Those of Ion Exchange Membranes

Advent Technologies Holdings, Inc. (NASDAQ: ADN) (“Advent”) today reported that bookings and shipments of their materials for redox flow batteries (RFBs) in the first quarter of 2021 rose by 500 percent year-over-year. Advent’s materials apply to renewable energy storage and production, including the membrane electrode assemblies used in high temperature fuel cells.

Dr. Emory DeCastro, Advent Technologies Chief Technology Officer, commented: “Advent’s materials solve critical problems for flow batteries by making utility-scale energy storage devices cost effective. Our tremendous year-over-year increase not only represents the start of new supply agreements, but it is also our most significant contribution into commercial redox flow battery systems to date. The ability to provide increasing quantities of customer-specific components also reinforces our strategy of using Advent manufacturing processes at third party production facilities.”

Advent Materials for Redox Flow Batteries

Advent produces membranes and electrodes for flow battery chemistries that will enable long-term storage of excess power during off-peak periods, and it will address the asymmetry between the demand and supply of solar and wind-generated power. Advent’s membranes for RFBs offer a longer lifetime at a lower cost than typical ion exchange membranes.

Currently, with mass-production capabilities, Advent is developing low cost, high quality electrodes for the leading RFBs chemistries. New membranes from Advent’s participation in the Advanced Research Projects Agency–Energy (“ARPA-E”) program show great potential to lower costs and increase selectivity for the vanadium RFBs. These membranes demonstrate how Advent is able to engineer properties into critical materials for customers.

Benefits of Redox Flow Batteries

RFBs are considered a vital bridging technology for intermittent power generation from renewable sources such as wind and solar. They offer a viable alternative to Lithium-ion batteries (LIBs) for stationary energy storage, especially for extended operation. Since LIBs store all their energy in one package, this leads to some serious safety concerns – especially for the outbreak of highly combustive fires that need highly specialized equipment to contain. On the other hand, RFBs keep the energy in separate tanks that are easy to isolate in the case of a mishap.

RFBs can address a variety of markets that are not appropriate for LIBs. For example, in the case of RFBs, if more energy (kWh) is needed, bigger tanks can be built; and if more power (kW) is needed, a larger stack can be used without changing the tank size.
