Clean Energy Technologies, Inc. (CETY) Stock Price & How to Invest
Last updated July 2026
Short answer
You can invest in Clean Energy Technologies (CETY) by buying shares or fractional shares at any major US broker, where it trades on the Nasdaq. CETY is an Irvine, California micro-cap that builds clean-energy hardware: waste-heat-to-power systems using its patented Clean Cycle ORC generator, waste-to-energy pyrolysis under its HTAP platform (which produces renewable gas, power, and biochar), and battery energy storage projects. The thesis is a leveraged bet on a stream of pilot projects, letters of intent, and partnerships converting into recurring revenue. Be clear-eyed: this is a tiny, unprofitable, deeply speculative company with very low revenue, ongoing losses, and Nasdaq compliance problems that create real delisting risk.

What does Clean Energy Technologies, Inc. (CETY) do?
Clean Energy Technologies, Inc. (CETY) is a small clean-energy technology company headquartered in Irvine, California, that designs and sells systems to turn wasted heat and waste materials into usable power. Its core products are Waste Heat Recovery Solutions built around the patented Clean Cycle generator, an Organic Rankine Cycle (ORC) machine that converts low-grade heat from industrial processes into electricity, and Waste-to-Energy solutions under its HTAP pyrolysis platform, which converts biomass and organic waste into renewable gas, power, and biochar. The company also pursues battery energy storage (BESS) projects and targets sectors such as cement, steel, glass, oil and gas, biomass, anaerobic digestion facilities, and, more recently, data centers.
The reality behind the technology story is a very early-stage, thinly capitalized business. Reported revenue is tiny (roughly $2 million in 2025, down from the prior year) while losses widened, so the company is far from profitable and its pipeline is dominated by letters of intent, memoranda of understanding, and pilot-scale deals rather than large recurring contracts. Recent developments include an LOI with Hoppy Power for an HTAP waste-to-energy pilot in Alberta, a development MOU with METIS Power for a modular waste-to-energy platform, regulatory progress on a renewable gas project in Vermont, and a battery-storage project in New York. Importantly, CETY received Nasdaq deficiency notices in 2026 for failing to timely file its annual and quarterly reports, which does not immediately halt trading but creates a real path to delisting if not resolved. This combination of intriguing technology and severe financial and compliance fragility defines the stock.
What's driving Clean Energy Technologies, Inc. (CETY)?
1. ORC waste-heat-to-power niche
CETY's Clean Cycle ORC generator captures low-grade industrial waste heat and turns it into electricity, a real efficiency and decarbonization need across cement, steel, glass, oil and gas, and geothermal. The company has installed prior-generation units many times over the years and is enhancing larger-scale systems. Demand for on-site clean power is a genuine tailwind, if CETY can convert interest into repeat orders.
2. HTAP waste-to-energy platform
The HTAP pyrolysis platform converts biomass and organic waste into renewable natural gas, power, and biochar, and CETY has pitched it for anaerobic digestion facilities to boost RNG output. Management has floated large per-installation value figures, but these are illustrative and depend on feedstock, scale, and regulatory approvals. The platform is the company's biggest growth narrative and its biggest execution question.
3. Partnerships and project pipeline
CETY's growth strategy runs through partnerships and early-stage deals: an LOI with Hoppy Power for an Alberta pilot, an MOU with METIS Power for modular units, a Vermont renewable gas project clearing regulatory steps, and a New York battery-storage project. These validate interest, but LOIs and MOUs are non-binding and pilot-scale, so the key is how many convert into signed, revenue-generating contracts.
4. New end-markets including data centers
CETY has signaled intent to develop energy-efficient solutions for AI data centers and crypto miners, tapping into surging power demand from computing. Positioning ORC and distributed-generation technology toward data centers is an on-trend narrative that could expand the addressable market. As with its other initiatives, the opportunity is early and unproven at commercial scale.
What are the risks to Clean Energy Technologies, Inc. (CETY)?
CETY is a highly speculative micro-cap and the risks are severe. Revenue is tiny (around $2 million in 2025) and falling, losses are widening, and the company is not profitable, so it likely depends on external financing that can dilute shareholders. In 2026 it received Nasdaq deficiency notices for failing to timely file its annual (10-K) and quarterly (10-Q) reports; while trading was not immediately halted, unresolved non-compliance could lead to delisting, potentially by late 2026, which is a serious and specific risk. Much of the pipeline consists of non-binding LOIs and MOUs and pilot-scale projects that may never scale into meaningful recurring revenue. The stock is thinly traded and extremely volatile, and micro-caps like this can move violently on single press releases. Investors should treat a position as money they can afford to lose entirely.
How is Clean Energy Technologies, Inc. (CETY) valued? (approximate, Jul 2026)
A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Clean Energy Technologies, Inc.'s investor relations page or your broker.
- Revenue trend: Very small and declining; roughly $2 million in 2025, down about 11% year over year (approximate, verify live)
- Profitability: Unprofitable with widening losses; 2025 net loss was materially larger than 2024, so no positive earnings to value against
- Balance sheet: Thinly capitalized; likely reliant on external financing that can dilute existing shareholders (verify the latest filing)
- Market cap tier: Micro-cap / speculative; verify the current figure live because the low-priced share moves sharply
- Listing status: Nasdaq-listed but received 2026 deficiency notices for late 10-K and 10-Q filings; delisting risk if not cured (possibly by late 2026)
- Valuation note: Standard earnings multiples do not apply because there are no profits; the stock trades on story, pipeline, and financing news
All figures are approximate and tied to the asOf date; because CETY has had late regulatory filings, published financials may be dated, so verify the latest available numbers and filings before acting. With negligible revenue and ongoing losses, price-to-earnings and similar ratios are meaningless here. The stock is valued on narrative (technology, partnerships, pipeline) and on the market's read of financing and delisting risk, not on current fundamentals. Treat any position as high-risk speculation.
Who competes with Clean Energy Technologies, Inc. (CETY)?
ORC and waste-heat-to-power specialists
In organic Rankine cycle and waste-heat-to-power, CETY sits alongside far larger and better-established players such as Ormat Technologies and Turboden, plus its own partner Exergy International, which supplies high-capacity radial-outflow-turbine ORC systems. These rivals have deeper resources and installed bases, underscoring how small CETY is within its own niche.
Waste-to-energy and renewable gas providers
CETY's HTAP pyrolysis and renewable gas ambitions compete in a crowded field of waste-to-energy, biochar, and RNG developers, from industrial gas and engineering firms to numerous private and venture-backed startups. Scale, financing, and proven commercial installations separate the leaders, areas where CETY remains early-stage.
Broader clean-energy and storage exposure
Investors wanting the clean-energy or battery-storage theme without single-stock micro-cap risk can use diversified clean-energy or renewable-infrastructure ETFs. These spread risk across many companies and avoid the delisting and liquidity risks specific to a name like CETY, at the cost of concentrated upside if CETY's technology were to succeed.

FAQ
Is CETY a good stock to buy right now?
+
That depends on your goals, time horizon, and risk tolerance, and this is not investment advice. The bull case is interesting clean-energy technology (ORC heat recovery and HTAP waste-to-energy) and a growing list of partnerships and pilots. The bear case is severe: tiny and falling revenue, widening losses, likely dilution, and Nasdaq deficiency notices that create real delisting risk. This is speculative money-you-can-lose territory, not a core holding.
What does Clean Energy Technologies actually do?
+
CETY designs and sells clean-energy hardware. Its main products are Waste Heat Recovery systems built on the patented Clean Cycle ORC generator, which turns industrial waste heat into electricity, and Waste-to-Energy systems under its HTAP pyrolysis platform, which convert biomass and organic waste into renewable gas, power, and biochar. It also pursues battery energy storage projects and targets sectors from cement and steel to data centers.
Why is CETY at risk of being delisted?
+
In 2026 CETY received Nasdaq deficiency notices for failing to file its annual report (Form 10-K) and a quarterly report (Form 10-Q) on time, which breaches Nasdaq listing rules. The notices did not immediately halt trading, but the company must submit compliance plans and file the reports; if it fails to regain compliance within the allowed window, potentially by late 2026, Nasdaq could move to delist the stock.
Is CETY profitable?
+
No. CETY reported only about $2 million in revenue in 2025, down from the prior year, while its net loss widened. It is an early-stage, story-driven company that is far from profitability and likely depends on outside financing to fund operations. Because some filings have been late, always check the most recent available financials before drawing conclusions.
What is the HTAP platform?
+
HTAP is CETY's high-temperature pyrolysis platform that converts biomass and organic waste into renewable natural gas, electricity, and biochar. The company has promoted it for anaerobic digestion facilities to increase RNG production and turn digestate into biochar. Management has cited large potential per-installation values, but those figures are illustrative and depend on feedstock, scale, regional markets, and regulatory approvals.
Why is CETY stock so volatile?
+
CETY is a low-priced, thinly traded micro-cap whose pipeline is built on non-binding LOIs, MOUs, and pilot projects, so a single press release, financing announcement, or Nasdaq update can move the shares sharply. Low liquidity amplifies these swings in both directions. Volatility like this is characteristic of speculative small-cap clean-energy names, not established companies.
Are CETY's partnerships and projects real revenue yet?
+
Most are early-stage. Announcements like the Hoppy Power LOI, the METIS Power MOU, the Vermont renewable gas project, and the New York battery-storage project show interest and progress, but LOIs and MOUs are non-binding and many deals are pilot-scale. The key question for investors is how many convert into signed, recurring, revenue-generating contracts, which remains unproven.
Who are CETY's competitors?
+
In ORC and waste-heat-to-power, CETY competes with much larger names such as Ormat Technologies and Turboden, and works with partner Exergy International. In waste-to-energy and renewable gas it faces a crowded field of engineering firms and startups. CETY is very small relative to these players, which have deeper resources and larger installed bases.
How can I get clean-energy exposure without CETY's risk?
+
Diversified clean-energy, renewable-infrastructure, or battery-storage ETFs spread exposure across many companies and avoid the delisting, dilution, and liquidity risks specific to a micro-cap like CETY. The trade-off is that a broad fund dilutes the concentrated upside you would get if CETY's technology succeeded. Always check a fund's holdings before assuming any particular exposure.
