TL;DR
TechCrunch named 22 clean‑tech and energy startups among its Startup Battlefield 200 selectees, highlighting companies working on battery recycling, AI carbon accounting, on‑site power, water treatment and other climate‑focused technologies. The list showcases early‑stage ventures pitching novel materials, robotics, and software tools designed to reduce waste and improve energy use; claims about performance and cost come from the companies themselves.
What happened
TechCrunch’s Startup Battlefield process winnowed thousands of applicants into a 200‑company pool; from that group, 22 clean‑tech and energy startups were highlighted as part of the Startup Battlefield 200. The roundup summarizes each company’s core product and why TechCrunch included it, citing examples that range from bio‑based battery metal recovery and compostable menstrual products to AI platforms for carbon accounting and marketplaces for excess energy capacity. Several companies emphasize claims of greater efficiency, lower cost or easier deployment compared with incumbents — for example, ultracapacitors with higher energy density, a combustion‑free fuel cell aimed at data centers, and a photocatalyst for advanced water treatment. The writeup frames these startups as notable entrants in the broader Disrupt competition and records the specific technical approaches they say they are pursuing.
Why it matters
- The cohort illustrates the variety of approaches being applied to emissions, waste and resource problems — from materials and chemistry to AI, robotics and distributed energy.
- Many startups promote solutions intended to integrate with existing infrastructure or lower barriers to deployment, which could accelerate adoption if claims hold up.
- Several companies focus on resource circularity (battery and textile recycling, compostable products, waste‑to‑product chemistry), a key area for reducing lifecycle emissions.
- The selection signals where early‑stage innovation attention is concentrated in cleantech: energy storage, carbon conversion/accounting, distributed generation and water treatment.
Key facts
- Startup Battlefield annually receives thousands of applicants; organizers trimmed that pool to a top 200 selectees.
- Of the top 200, a final group of 20 competes live for the Startup Battlefield Cup and a $100,000 cash prize.
- TechCrunch highlighted 22 clean‑tech and energy companies among the Battlefield 200; the list includes AraBat, Aruna Revolution, CarbonBridge, Carbon Negative Solutions and others.
- AraBat says it recovers critical battery metals using a bio‑based process that relies on plant waste such as citrus peels rather than traditional toxic reagents.
- Aruna Revolution offers a compostable menstrual pad made from agricultural by‑products designed to decompose quickly without plastics or harmful chemicals.
- CarbonBridge builds bioreactors for microbial gas fermentation to convert waste gases like methane and CO₂ into useful molecules and says its process is more efficient than alternatives.
- Carbon Negative Solutions describes an AI‑driven platform that converts industrial wastes and minerals into cement claimed to be carbon negative and compatible with standard equipment.
- Companies on the list cover diverse technologies: marketplaces for excess enterprise energy (COI Energy), AI carbon accounting with blockchain traceability (Coral), and higher‑density ultracapacitors (EnyGy).
- Several firms emphasize deployment advantages: Gemini Energy markets a non‑combustion fuel cell for on‑site power that it says can be deployed in months, and Helix Earth touts retrofit‑friendly rooftop systems.

Quick glossary
- Ultracapacitor: An energy storage device that stores electrical charge electrostatically and can deliver high power bursts; it sits between conventional capacitors and batteries in energy and power characteristics.
- Bioreactor: A controlled system that supports biologically active environments, often used to grow microorganisms or cells for processes such as fermentation or biochemical conversions.
- Carbon accounting: The practice of measuring and tracking greenhouse gas emissions associated with an organization, product or activity, often for reporting and compliance purposes.
- Photocatalyst: A substance that uses light to accelerate chemical reactions, commonly explored for pollutant degradation and water‑treatment applications.
- Fuel cell: A device that converts chemical energy from a fuel (often hydrogen or other gases) directly into electricity through an electrochemical reaction rather than combustion.
