What Redoxblox, Inc. does
Redoxblox, Inc., now operating as Tempo, is a San Diego-based private company that develops thermochemical energy storage systems intended to decarbonize industrial heat and provide long-duration grid storage. The core product, branded the Tempo Thermochemical Battery System, uses mixed metal oxides derived from simple non-toxic elements to store energy through a three-phase cycle: charging from electricity when costs are lowest, banking the energy in a compact thermochemical form, and discharging superheated air on demand. The system delivers continuous heat up to 1200°C and reaches a full charge in approximately four hours, enabling an energy-cost-arbitrage use case the company describes as 'buy low, heat high.'
The technology is positioned for drop-in deployment across heavy-industrial processes without facility overhauls, with named target verticals spanning pharmaceuticals, cosmetics, consumer products, cement, metals, petroleum products, pulp and paper, and food and beverage. In addition to on-site industrial heat, the company is pursuing long-duration grid-scale storage for utilities and grid operators, though access to US wholesale energy markets is currently constrained by Federal Power Act classification of thermal storage as a passive industrial load.
The business model is enterprise hardware sales through a direct consultation-based sales motion, with no publicly disclosed pricing and no named commercial customers in the input data. The company closed a $40.7M Series A in October 2024 led by Prelude Ventures with Breakthrough Energy Ventures, Khosla Ventures, Imperative Ventures, and New System Ventures, and appointed former ChargePoint President and CEO Pasquale Romano as CEO to drive commercialization.

Redoxblox, Inc. product offering
Product offeringCore offering
Redoxblox (rebranded as Tempo) designs and sells thermochemical battery hardware that uses mixed metal oxides to store energy as heat and discharge continuous temperatures up to 1200°C on demand. The system enables industrial manufacturers to electrify process heat, capturing low-cost electricity during off-peak hours and converting it to reliable high-temperature thermal energy for applications such as synthesis, drying, sterilization, calcining, and steam generation.
Product overview
Tempo (formerly Redoxblox) offers a unified thermochemical energy storage product designed for industrial heat electrification. The core Tempo system provides continuous heat delivery up to 1200°C using thermochemical storage technology with mixed metal oxide materials. The product operates through a three-phase cycle (Power/Charge, Bank/Store, Deploy/Discharge) enabling industrial facilities to purchase electricity when costs are low and deploy high-temperature heat on their schedule. The system is designed for scalability across various industrial applications including pharmaceuticals, cement, metals, petroleum products, pulp & paper, food & beverage, cosmetics, and consumer products, without requiring facility-wide overhauls.
