The product’s design uses a low-temperature reaction of air and fuel to drive magnets through copper coils to efficiently produce electricity. The company said this design, combined with the company’s adaptive control software, enables near-zero NOx emissions, full dispatchability, and seamless switching between natural gas and renewable fuels like biogas and hydrogen. The product’s load-following capability also means it pairs well with onsite solar or battery storage, dispatching power when needed. More info available here

End-of-warranty assessments

Engineering company Solar Support now offers independent plant and equipment end-of-warranty assessment services for utility-scale solar PV asset owners. The company said the services include onsite review of system and equipment performance, as well as detailed documentation owners can use to secure support before EPC and manufacturer warranties lapse. This work builds upon Solar Support’s inverter predictive analysis program launched last fall.

The company said warranty length varies—typically two years for construction and five years for equipment such as central inverters. Given a 28- to 35-year plant lifespan, asset owners could face full responsibility for decades of maintenance and repair after warranties expire. More info available here.

Hydrogen energy storage

T2M Global recently was awarded a $1.3 million project from the California Energy Commission (CEC) to develop and validate its Advanced Electrolyzer System (AES) technology, a 100 kW-class green electrolytic hydrogen energy storage module. When successful, the company claimed, the electrical system efficiency of this hydrogen electrolyzer will double compared to some existing products in the market today. The AES system can be powered by using excess electricity or other waste energy streams. CEC solicited proposals to fund the development of emerging energy storage technologies to diversify its portfolio. More info available here.

Deep-cycle battery

KiloVault unveiled its new 2V 1000 XLC lead carbon, sealed AGM, deep-cycle energy storage battery. Designed for optimum performance in partial-state-of-charge applications, the XLC is well suited for high-demand off-grid or battery backup applications. The company said the XLC provides flexible and reliable storage for smart grids, hybrid power supply systems, and microgrids.

The XLC offers the same function as KiloVault’s PLC 2100 battery, but is designed to handle greater energy demands with 1,000 amp-hours of energy storage. Each 2-Volt XLC has a capacity of 2000 Wh, and up to four 48 V strings can be wired in parallel, for a maximum battery bank size of 24 batteries. More info available here.

Bi-directional EV charger

Rhombus Energy Solutions received certification of its bi-directional 125 kW DC electric vehicle (EV) fast charger to the Underwriter Laboratories 1741-SA standard. The standard defines the design and testing requirements to certify that bi-directional, grid-tied, “smart” inverters and EV chargers can be safely used to support distributed generation grid services and applications.

This latest certification now provides medium- and heavy-duty (M/HD) EV fleet operators with two Rhombus products to meet their needs: the Rhombus 125 kW charger and the previously certified Rhombus 60 kW charger. Since both of these chargers and their associated dispensers are bi-directional certified, they can now be used in vehicle-to-everything and unidirectional charging applications.
