Moxion Power is a California-based clean energy startup building mobile, maintenance-free battery-powered generators intended to replace diesel generators. Its mobile energy storage units are designed for temporary power needs across construction, events & entertainment, utilities, EV fleet operators, and government agencies. The company says its units can be deployed within hours and operate quietly and emission-free, enabling indoor use and reduced cabling on film sets. Moxion designs, engineers, and manufactures its core technologies and battery modules in-house, according to CEO Paul Huelskamp. The startup emphasizes lower maintenance and higher efficiency compared with diesel generators. Financially, Moxion has raised a total of $110 million from strategic and institutional backers. Amazon has also leased units for two video productions, illustrating early commercial deployments and customer interest.

Moxion Power builds portable, battery-powered generators intended to replace diesel generators used at construction sites, film locations, festivals and during public-safety outages. The company's first product is a midsized generator in the 20 kV to 100 kV range designed to provide similar runtime to an equivalent diesel unit. Moxion designs, engineers and builds its products in Richmond, California, and currently uses lithium-iron-phosphate (LFP) cells while remaining agnostic to cell chemistry and form factor. It operates a swap-and-charge model where depleted units are swapped and recharged at Level 2 or DC fast speeds; the company plans to power recharging with renewables and is developing telematics and software to automate dispatch and charging. Founded in 2020 and a member of Y Combinator's winter 2021 cohort, Moxion is targeting high-utilization rental and day-to-day applications where battery operating and maintenance savings can offset higher upfront costs. The company recently raised $100M in a Series B to scale production, with its first plant under construction and a second planned in 2024 to yield over 7 GWh of generators annually; Sunbelt Rentals has committed to purchasing units through 2025. Moxion Power manufactures mobile energy storage technology and operates an all-electric equipment rental business aimed at replacing diesel generators across construction, events, transportation, film production, and telecommunications. Its vertically integrated model is powered by AI and software to manage large fleets and deliver rental services and a customer experience optimized for equipment rental. The company’s products are engineered to meet the demands of the construction industry and to reduce the noise, operating costs, and emissions associated with diesel generators. Moxion has pilot rental programs with major general contractors including Turner, Swinerton, Webcor, and DPR, and has signed letters-of-intent with large construction firms and EV fleet operators. The company plans to open its first rental location in the San Francisco Bay Area in Q3 2022 and will use new funding to scale manufacturing and fulfill a significant backlog of customer orders. Moxion is headquartered in Richmond, CA; its founders have backgrounds in battery engineering, vehicle electrification, renewable energy project finance, and construction.

Viridi Parente develops fail-safe, point-of-use lithium-ion battery systems for mobile and stationary applications. Its Green Machine brand supplies portable packs for construction and heavy industrial markets and has logged over 250,000 hours of field use. Its Volta Energy brand offers fail-safe stationary battery systems configurable from 50 kWh to 5 MW for data centers, manufacturing, commercial, medical, residential and other occupied spaces. The company emphasizes safety and resilience using materials and thermal management technologies derived from aerospace and military applications and is partnering with KULR Technology Group to integrate patented safety tech. Viridi aims to manufacture its fail-safe battery technology at scale and to repurpose abandoned manufacturing sites to create jobs in economically depressed urban areas. The company recently completed a significant financing to support increased production and broader market deployment. Viridi Parente manufactures renewable power systems that use proprietary lithium-ion cells, modules, and drives for industrial applications, microgrid storage, and replacements for fossil fuel–based engine systems. Through subsidiaries Green Machine Equipment (launched in 2010) and Volta Energy Products (founded in 2017), the company focuses on replacing diesel power sources and designing in-place distributed energy systems that provide instantaneous backup, peak shave demand costs, and a balanced energy profile. Led by Chairman & CEO Jon M. Williams, Viridi Parente develops systems for heavy machinery and storage applications and for microgrid deployments. The company is preparing to install its first distributed storage system to support a high-powered cryo-electron microscope at the Hauptman-Woodward Medical Research Institute in Buffalo. Financially, Viridi Parente secured a $29M Series B that values the company at approximately $80M. The round was led by Grand Oaks Capital with participation from Impact Capital of New York, Varia Ventures, the Western New York Impact Investment Fund, and private investors.
