VRB

VRB is an acronym used for several distinct concepts in different fields. Notably, it refers to an IATA airport code, to a financial instrument, and to a technology in energy storage (vanadium redox battery).

In aviation, VRB is the IATA code for Vero Beach Municipal Airport, a public airport located in Florida. The code is used in airline timetables, flight planning, and ticketing to identify the facility.

In finance, VRB stands for variable-rate bond, a bond with a coupon that resets at intervals according to a reference rate plus a spread. These bonds have payments that change over time, in contrast to fixed-rate bonds. Reset intervals vary; common references include SOFR or other benchmarks. They are often issued to manage interest-rate risk or to achieve lower initial coupons; investors face rate risk and sometimes credit risk.

In energy storage, VRB commonly denotes vanadium redox battery (VRB) or vanadium redox flow battery, a rechargeable flow battery that stores energy in electrolyte solutions containing vanadium ions. The energy capacity is determined by electrolyte volume; power capacity by the size of the electrochemical cells and membranes. Advantages include scalability, long cycle life, and the ability to treat energy and power separately; drawbacks include complexity and cost.
