Company Overview

Chakr Innovation is an Indian cleantech and material science company that designs and manufactures emission control technologies for diesel generators and related industrial equipment. Founded in 2016 by graduates of IIT Delhi, the company built its business around a single environmental problem: particulate and gas emissions from diesel generator sets, a major and persistent source of urban and industrial air pollution in India.

The company’s core offering is the Chakr Shield, a retrofit emission control device (RECD) that attaches to existing diesel generators without requiring their replacement. Chakr Innovation was the first company in India to receive Type Approval certification for an RECD from labs accredited by the Central Pollution Control Board.

Over time, the product line has expanded to include a dual fuel kit that blends diesel with natural gas, a nitrogen oxide reduction system, an IoT-based generator monitoring platform, and a dust suppression system for construction sites. The company also operates an annual maintenance contract service for its installed devices and is developing aluminium-air battery technology as an indigenous alternative to lithium-ion energy storage.

Chakr Innovation is headquartered in Gurugram, Haryana, with additional offices in Pune and Chennai, and manufacturing facilities across northern and western India. The company has raised multiple funding rounds from institutional and strategic investors and has expanded its customer base across manufacturing, healthcare, real estate, data center, and hospitality sectors.

Why These SDGs Matter

Chakr Innovation’s core technology reduces particulate matter, hydrocarbons, and carbon monoxide from diesel generator exhaust, directly supporting SDG 3 by limiting airborne pollutants linked to respiratory and cardiovascular illness. Its emission control devices are engineered and manufactured in-house using proprietary material science, aligning with SDG 9’s focus on building resilient infrastructure and fostering industrial innovation.

Because diesel generators are widely used for backup power in Indian cities, reducing their emissions has a direct bearing on urban air quality, connecting the company’s work to SDG 11. The conversion of captured particulate matter into usable ink and pigment products reflects a circular, resource-recovery approach central to SDG 12. Finally, by cutting harmful combustion emissions at scale across thousands of installations, Chakr Innovation contributes measurably to SDG 13’s climate action goals.

  • Nitrogen oxide emissions from industrial diesel and gas engines
  • Airborne dust pollution at construction and infrastructure sites
  • High diesel fuel consumption and associated operating costs
  • Need to retrofit generators without costly full replacement
Approach & Methodology

Chakr Innovation’s engineering approach centers on material science and retrofit design rather than replacing existing diesel generator infrastructure. The Chakr Shield attaches to a generator’s exhaust system and uses a proprietary filtration and catalytic process to trap particulate matter, hydrocarbons, and carbon monoxide before release, converting a portion of captured soot into usable ink and pigment products.

Products are tested and certified at CPCB-accredited laboratories, including ICAT and ARAI, and the company holds multiple patent filings related to its emission control technology. Its Dual Fuel Kit applies a fuel-blending methodology that allows generators to run on a mix of diesel and natural gas, reducing both emissions and fuel costs without engine modification.

The company complements its hardware with IoT-based monitoring (Chakr GenSense) that tracks generator performance and emission parameters remotely, supporting customers’ ongoing regulatory compliance. An in-house annual maintenance program addresses component wear and soot buildup that can otherwise degrade device performance over time.

Beyond emission control, Chakr Innovation’s R&D division is developing aluminium-air technology, an energy storage approach built on domestically sourced raw materials, positioned as a potential alternative to imported lithium-ion battery chemistries. Chakr Innovation collaborates with academic and industrial partners, including IIT Delhi and Indian Oil Corporation, on technology development and commercialisation.

Market Position

Chakr Innovation operates in India’s emission control and clean-tech equipment market, primarily serving businesses and institutions that rely on diesel generators for backup or primary power, including manufacturers, healthcare facilities, real estate developers, data centers, and hospitality operators. The company positions itself around being the first in India to secure CPCB Type Approval for a retrofit emission control device, a regulatory distinction that differentiates it from generic pollution control equipment suppliers.

Its technology differentiation lies in retrofit compatibility, meaning customers can achieve emissions compliance without replacing existing generator assets. With over 5,000 device installations and more than 2,000 customers reported as of its 2025 funding round, the company has built meaningful scale within the Indian retrofit emission control segment.

Procurement Considerations
  • Verify CPCB Type Approval status for the specific RECD model and generator kVA rating
  • Confirm compatibility with existing generator capacity, typically 15 kVA to 2000 kVA
  • Assess installation timelines and any operational downtime during retrofit
  • Evaluate annual maintenance contract terms and included service scope
  • Review compliance mapping to applicable CAQM, NCAP, CPCB, or state SPCB norms
  • Request documented emission reduction performance data from accredited test labs
  • Clarify warranty terms and expected device lifespan
  • Consider integration requirements for IoT monitoring with existing facility systems
Funding, Recognition & Ecosystem
  • Series C funding round of USD 23 million (INR 193.5 crore) led by Iron Pillar, announced September 2025

  • International recognition cited from the United Nations, WWF, and Forbes
  • Mentorship network includes Ajai Chowdhry, co-founder of HCL, and Rajiv Mehrishi, former Comptroller and Auditor General of India
  • Technology collaboration with Indian Oil Corporation and BOSCH India
Natnavi Analysis

Chakr Innovation occupies a specific and practical niche within India’s cleantech landscape: making diesel generators, which remain widespread across Indian industry and commerce, compliant with tightening emission norms without requiring costly asset replacement. This retrofit-first approach lowers the barrier to compliance for businesses that cannot easily transition away from diesel backup power in the near term.

The company’s regulatory first-mover position, being the first in India to receive CPCB Type Approval for a retrofit emission control device, gives it a credibility advantage in a market where compliance documentation matters to procurement decisions. Its reported installation base and repeat institutional funding suggest genuine commercial traction rather than early-stage speculation.

At the same time, Chakr Innovation’s core business remains tied to a transitional technology. Diesel generators themselves are not a long-term clean energy solution, and the company’s emission control devices treat symptoms of fossil fuel combustion rather than eliminating it. Its expansion into dual fuel systems, monitoring platforms, and now aluminium-air energy storage suggests an awareness of this limitation and a deliberate move toward broader clean-tech relevance. For procurement teams facing near-term regulatory deadlines around diesel generator emissions, Chakr Innovation represents a documented, scalable compliance pathway.
