About Clean Energy Technologies Inc
Natural Gas Distribution · NASDAQ
Clean Energy Technologies, Inc. (NASDAQ: CETY) is a clean energy technology company that focuses on waste-to-energy, power generation, energy storage, and heat-to-power solutions. Headquartered in Irvine, California, the company describes itself as a participant in the zero-emission transition by offering eco-friendly green energy solutions, clean energy fuels, and alternative electric power for small and mid-sized projects in North America, Europe, and Asia.
According to company disclosures, Clean Energy Technologies delivers power from heat and biomass with zero emission and low cost. Its principal products include Waste Heat Recovery Solutions that use the patented Clean Cycle™ generator to create electricity from waste heat streams. The company also offers Waste to Energy Solutions that convert waste products created in manufacturing, agriculture, wastewater treatment plants, and other industries into electricity and biochar. These solutions are intended to address both energy efficiency and environmental sustainability by capturing energy that would otherwise be lost or by transforming waste materials into useful outputs.
Beyond equipment and systems, Clean Energy Technologies provides Engineering, Consulting and Project Management Solutions. The company states that these capabilities support the development of clean energy projects for municipal and industrial customers and for Engineering, Procurement and Construction (EPC) companies. In various announcements, CETY also highlights its role as an EPC contractor on specific projects, reflecting a business model that combines technology, project development, and implementation services.
Business segments and markets served
Clean Energy Technologies has described its operations as organized into multiple business areas. In prior descriptions, the company referenced segments including Clean Energy HRS & CETY Europe, CETY Renewables Waste to Energy Solutions, an Engineering and Manufacturing Business, and CETY HK. Across these activities, CETY indicates that it serves markets such as industrial, aerospace, military, instrumentation, and medical, as well as municipal and other industrial users that generate waste heat or waste streams suitable for conversion.
The company’s waste heat recovery business centers on the Clean Cycle™ generator and Organic Rankine Cycle (ORC) technology. In one project highlighted by CETY, its Clean Cycle II™ ORC system was deployed in an industrial manufacturing setting to recapture waste heat and convert it into electricity. This type of application illustrates how CETY’s technology can be integrated into existing industrial processes to improve energy efficiency and reduce energy costs by turning previously unused heat into a power source.
Waste-to-energy and biomass-based power
CETY’s Waste to Energy Solutions are described as converting waste products from manufacturing, agriculture, and wastewater treatment into electricity and biochar. In connection with its affiliate Vermont Renewable Gas, LLC, CETY has discussed a proposed agricultural waste-to-energy facility in Lyndon, Vermont. That project is designed to use advanced pyrolysis and gasification technologies to convert farm-derived biomass into renewable synthetic gas for clean combustion, with the goal of generating renewable baseload power, reducing methane emissions from agricultural waste, and producing biochar that can support carbon sequestration.
The company has also announced a High Temperature Ablative Pyrolysis (HTAP™) platform tailored for integration with anaerobic digestion and renewable natural gas (RNG) facilities. CETY states that this technology thermochemically converts forestry residues, agricultural waste, and other non-food biomass inputs into clean syngas. When paired with methanation systems, that syngas can be upgraded to pipeline-quality RNG. The same platform is described as addressing digestate management by converting digestate into syngas and biochar, potentially supporting onsite power or additional RNG production.
Energy storage and grid-focused projects
In addition to heat and waste-to-energy technologies, Clean Energy Technologies is active in battery energy storage projects. The company has announced a standalone Battery Energy Storage System (BESS) project in New York State, involving a multi-megawatt, multi-megawatt-hour storage installation intended to support grid reliability, peak shaving, and participation in New York’s Value of Distributed Energy Resources (VDER) program and ancillary grid services. CETY has also disclosed a letter of intent to serve as EPC contractor for multiple BESS projects across New York, each expected to integrate energy storage with rooftop solar and electric vehicle charging loads.
In these storage projects, CETY’s role as EPC contractor encompasses planning, engineering and system design, procurement of storage hardware and balance-of-system equipment, construction and installation, testing and commissioning, and compliance with applicable regulatory and labor requirements. These activities extend the company’s presence beyond equipment supply into full project delivery for distributed energy and grid-support applications.
Geothermal and other clean power initiatives
Clean Energy Technologies has also announced a strategic collaboration to advance the DeepFyre™ geothermal power system, which is described as targeting scalable, zero-emission baseload power for island nations and emerging markets. In that collaboration, CETY’s proprietary heat-to-power and ORC systems, and its strategic alliance with Exergy International Srl, are combined with a monobore geothermal platform from Qymera Global Energy Ltd. The companies have outlined plans for modular geothermal units designed to reduce drilling complexity and accelerate deployment of geothermal power in regions with high geothermal potential.
Beyond geothermal, CETY has indicated that it is exploring specialized energy-efficient solutions for artificial intelligence (AI) data centers and cryptocurrency mining operations. The company has referenced potential offerings such as AI-driven energy management systems, battery storage, and cooling technology aimed at lowering operating costs for data centers. It has also announced a partnership with METIS Power Inc. to introduce a mobile, modular power and mining solution that pairs mobile cryptomining units with mobile power generation, allowing operators to deploy and relocate mining capacity without relying solely on local grid infrastructure.
Corporate structure, capital markets and regulatory context
Clean Energy Technologies, Inc. is incorporated in Nevada and files periodic reports and current reports with the U.S. Securities and Exchange Commission (SEC) under Commission File Number 001-41654. The company has disclosed that its common stock trades on the Nasdaq Capital Market under the symbol CETY. In one Form 8-K, CETY reported a 1-for-15 reverse stock split of its authorized and outstanding common stock, implemented via a Certificate of Change filed with the State of Nevada, with the stated purpose of restoring compliance with Nasdaq’s minimum bid price requirements. Nasdaq later confirmed that CETY regained compliance with the minimum bid price standard.
The company has also reported several financing transactions through convertible promissory notes and equity subscriptions, describing the use of proceeds for working capital and business development. Notifications of late filing on Form 12b-25 indicate that CETY has, at times, required additional time to assemble financial information for its quarterly reports, while stating its intention to file within the permitted extension period.
How CETY positions itself within clean energy
Across its public statements, Clean Energy Technologies presents a business that combines technology development, project execution, and engineering services across multiple clean energy domains: waste heat to power, waste-to-energy, biomass-based power, battery energy storage, geothermal power, and specialized applications for data centers and crypto mining. The company emphasizes the use of technologies such as Organic Rankine Cycle systems, HTAP™ pyrolysis, and integrated EPC capabilities to deliver projects for industrial, municipal, and infrastructure customers.
Investors and analysts reviewing CETY often look at how these various activities contribute to the company’s overall project pipeline, its role as an equipment provider and EPC contractor, and its participation in markets where energy efficiency, emissions reduction, and distributed generation are priorities. For detailed financial information, risk factors, and segment reporting, CETY directs readers to its periodic reports on Forms 10-K and 10-Q and its current reports on Form 8-K filed with the SEC.
