Abstract: An apparatus for providing normalized hydrogen correction factor comprises: a set of sensors configured to measure telemetry data of a hydrogen production plant; a memory; a database; and a processor operatively coupled to the memory, the database, and the set of sensors. The processor is configured to: receive the telemetry data from the set of sensors; receive supplier data from the database; receive customer data from a customer; determine, using a machine learning model stored in the memory, and based on the telemetry data, the supplier data, and the customer data, a normalized hydrogen correction factor; and provide the normalized hydrogen correction factor to the customer.

Abstract: According to one aspect, a power storage system may include an enclosure, and one or more modules disposed in the enclosure. Each of the one or more modules may include a plurality of electrochemical cells electrically coupled to one another, each one of the plurality of electrochemical cells including an oxygen evolution electrode (OEE), an anode, a gas diffusion electrode (GDE), an electrolyte, and a vessel and, within the vessel, the OEE, the anode, and the GDE at least partially immersed in the electrolyte.

Abstract: According to an aspect, an electrochemical cell may include a vessel, at least two instances of an anode assembly, at least two instances of an oxygen evolution electrode (OEE), and a gas diffusion electrode (GDE). In the vessel, the GDE may be disposed between mirrored arrangements of the at least two instances of the OEE and the at least two instances of the anode assembly.

Abstract: Embodiments are directed to a musical instrument having buttons, where the buttons determine the magnitude of the interval by which the melody will jump from the last note played. With a small number of interval buttons and an up/down strum bar, embodiments can play almost any melody and more notes than a piano. One embodiment is directed to an interval-based guitar including fret buttons whose input signals are used to calculate the interval by which to change the pitch of the prior note. Providing input via a strum bar or a sensor, a new note is generated by adding or subtracting the interval to/from the prior note to generate a new note.
