What florrent does
florrent is a bio-based materials and energy storage company that designs and manufactures supercapacitor products for short-duration power quality and reliability applications. Founded in 2020 in Amherst, Massachusetts, the company targets hyperscaler data centers, grid asset developers, utilities, and commercial/industrial facilities whose operations are sensitive to momentary voltage disturbances, peak demand charges, or battery degradation from high-ramp-rate cycling. Its core innovation is Contoured Carbon™, a patented activated carbon electrode material derived from domestically sourced biomass waste including hemp and pecan shells, which the company positions as a domestic alternative to imported coconut-shell-based activated carbon.
The company's product portfolio comprises three offerings: Contoured Carbon™ (the activated carbon material, also sold to other ultracapacitor manufacturers as a feedstock), floCAP™ (cylindrical 60138-form-factor supercapacitor cells designed for drop-in compatibility with industry-standard stacks), and floMOD™ (rack-mount-compatible supercapacitor modules with real-time condition reporting over CAN bus). The technology is reported to deliver a 55% increase in energy density over industry-standard EDLCs without sacrificing power, leakage current, ESR, or temperature window, and to enable approximately 60% lower total cost of ownership versus lead-acid batteries in comparable applications.
florrent operates a direct enterprise sales motion with custom quote-based pricing, multi-year contracts, and Field Applications Engineers providing on-site and remote technical support, proof-of-concept validation, and training. Operations are based in Massachusetts with a 5,000 sq ft R&D and office facility in Sunderland, a 5,500 sq ft pilot-scale activated carbon production facility in South Deerfield, and a planned third pilot manufacturing facility in Northampton scheduled for 2026. As of late 2025 the company had raised approximately $15.2 million in equity across pre-seed, seed, and seed-2 rounds plus non-dilutive grants, and remains in a pre-revenue or very early commercial stage with prototype shipments to initial grid asset developer and ultracapacitor manufacturer customers.

florrent product offering
Product offeringCore offering
florrent manufactures and sells bio-based supercapacitor products for short-duration Power Quality & Reliability applications. The portfolio comprises three named offerings: Contoured Carbon™ (a patented activated carbon electrode material derived from domestic biomass waste such as hemp and pecan shells), floCAP™ (a 60138-form-factor cylindrical supercapacitor cell), and floMOD™ (a rack-mount-compatible supercapacitor module with CAN-bus reporting). Products are sold as drop-in compatible replacements for industry-standard supercapacitor stacks serving data centers, grid operators, utilities, and commercial/industrial facilities.
Product overview
florrent is an energy technology company offering a portfolio of bio-based supercapacitor products engineered for Power Quality & Reliability (PQ&R) applications. The portfolio consists of three named offerings: (1) Contoured Carbon™ — the company's patented bio-derived activated carbon electrode material that is the core technical innovation enabling a 55% energy density improvement over industry-standard supercapacitors; (2) the floCAP™ — a 60138-form-factor cylindrical supercapacitor cell built with Contoured Carbon™; and (3) the floMOD™ — a rack-mount-compatible supercapacitor module with real-time CAN-based conditions reporting. Together these products provide short-duration power stability for data centers, grid infrastructure, and hybrid energy storage systems, sourced from domestically grown biomass waste.
