NDBI Targets 150M LoRaWAN Sensors With Nuclear Battery

Nuclear Diamond Batteries, Inc. (OTCID: NDBI) announced on 30 September 2026 the publication of a white paper examining whether betavoltaic micropower can power LoRaWAN wireless sensors, a market the LoRa Alliance put at more than 150 million connected devices as of 22 September 2026, growing at roughly 25% CAGR. The company, which operates through majority-owned subsidiary AtomiQ, Inc., said the paper maps 19 potential application sectors. NDBI confirmed it has not built, certified or commercialised a nuclear-powered LoRaWAN sensor.

Context — Why the LoRaWAN Power Problem Matters Now

LoRaWAN reached 150 million connected devices in September 2026, a base the LoRa Alliance said is expanding at approximately 25% CAGR. That installed base creates a maintenance liability the report frames as the central commercial question: sensors are increasingly deployed in locations where replacing a battery costs more than the sensor itself.

NDBI's white paper arrives on the back of that Alliance disclosure, published eight days before the company's announcement. The timing is deliberate. The company said it is not attempting to displace conventional batteries universally, but is targeting deployments where servicing the power source requires excavation, shutdowns, vehicles or specialised personnel.

Greg Rubin, CEO of AtomiQ, said the focus is on assets where battery replacement becomes "more expensive, difficult or mission-critical than the sensor itself" — buried infrastructure, pipelines, bridges, mines, remote environmental stations and defence installations. That is a narrow slice of the 150 million devices, but a high-value one.

The white paper distinguishes betavoltaic sources from electrochemical batteries on structural grounds. A betavoltaic device converts energy released through radioactive decay into continuous electrical output rather than storing a finite chemical charge. Output is low, so the paper proposes a hybrid architecture: a nuclear micropower source trickles charge into a capacitor or supercapacitor, which then supplies the short high-power pulse a radio needs to transmit.

Data — What the Numbers Show

The Alliance's September 2026 figures give the addressable ecosystem concrete scale. Beyond 150 million connected devices, it reported more than 695 certified devices, nearly 1,000 marketplace products and over 340 member organisations. Named deployments include ZENNER Connect at more than 11.6 million sensors, Netmore at 11.2 million active devices, The Things Industries at approximately 6 million connected devices, and Veolia at more than 4 million active smart meters in France.

Market sizing from independent research firms diverges sharply by methodology. Global Market Insights estimated the LoRaWAN market at approximately $3.7 billion in 2024 and projected roughly $75.8 billion by 2034, a 41.1% CAGR. Mordor Intelligence put the LoRa and LoRaWAN IoT connectivity market at approximately $10.71 billion in 2025, potentially reaching $44.76 billion by 2030, a 33.1% CAGR. The two estimates differ because the firms use different definitions and market boundaries.

Metric	Value	Source
LoRaWAN connected devices	150 million+	LoRa Alliance, Sept 2026
Device growth rate	~25% CAGR	LoRa Alliance
Betavoltaic segment CAGR	~15.8% through 2030	Mordor Intelligence
Betavoltaic market 2023	~$3.4 million	Valuates Reports
Betavoltaic market 2030	~$11.4 million	Valuates Reports

The betavoltaic forecasts sit orders of magnitude below the LoRaWAN connectivity figures. Valuates Reports valued the global betavoltaic battery market at approximately $3.4 million in 2023, projecting roughly $11.4 million by 2030, an estimated 18.7% CAGR. Mordor forecasts the betavoltaic segment of the broader nuclear-battery market at approximately 15.8% CAGR through 2030. NDBI said these third-party estimates should not be read as projections of its own revenue or market share.

Analysis — What It Means for Sensors and Small-Cap Exposure

The commercial logic rests on a cost asymmetry rather than a technology breakthrough. If a sensor sits in a mine, a buried pipeline or a defence installation, the servicing trip — personnel, vehicles, excavation, downtime — can exceed the cost of the electronics. That asymmetry is where a premium long-duration power source could justify its price, and the paper prioritises applications on exactly those grounds.

NDBI's intellectual property sits in AtomiQ. The portfolio includes U.S. Patent No. 12,394,534 B2, covering a diamond-based nuclear-voltaic architecture that converts radioisotope decay into electrical power. The USPTO has also issued Notices of Allowance for applications covering a high-porosity metal-organic framework electrode incorporating carbon nano-onion structures, plus synthesis and functionalisation methods. Additional applications remain pending.

The counter-argument is straightforward and the company states it plainly. No prototype exists. The energy budgets, reporting intervals and application rankings in the paper are conceptual or illustrative unless identified as measured results. The gap between a theoretical energy balance and a certified field device is where most betavoltaic concepts have stalled, and the report offers no measured data to close it.

Regulatory exposure compounds the technical risk. Development, possession, processing, manufacturing and distribution of products involving radioactive materials may require licensing and approvals from the U.S. Nuclear Regulatory Commission, applicable Agreement States and other authorities. Isotope availability and cost are listed among the company's stated risks.

Positioning is thin and speculative. NDBI trades on OTC Markets, where liquidity is limited and disclosure obligations are lighter than on major exchanges. The white paper is a narrative catalyst for a development-stage issuer, not an earnings event, and the paper itself concedes the next milestone is measurement rather than another projection.

Outlook — What to Watch Next

The company's stated roadmap runs from laboratory energy-budget validation and a bench-scale demonstrator, through an environmental beacon and field pilots, to ruggedised modules, satellite-capable configurations and application-specific products. No dates were attached to any stage, and the company did not disclose a timeline for the bench-scale demonstrator.

The first verifiable checkpoint is a complete measured energy balance: how much power is continuously generated, how efficiently it is stored, how much the sensor and radio consume, and how frequently the system transmits reliably. Rubin said that demonstration — not another forecast — is the milestone that matters.

Beyond that, watch for any satellite-capable configuration, since the paper examines combining terrestrial and satellite LoRaWAN connectivity for sensors outside conventional network coverage. Any field pilot announcement would be the first hard evidence the concept has left the laboratory. The company did not disclose financing terms, isotope suppliers or partnership agreements.

Frequently Asked Questions

What does a nuclear diamond battery actually power?

A betavoltaic device converts energy from radioactive decay into a small, continuous electrical output. Because wireless transmitters need brief high-power pulses above their average draw, NDBI's paper proposes using the nuclear source to trickle-charge a capacitor or supercapacitor, which then supplies the transmission pulse. The sensor itself, not the radio, may be the dominant energy consumer in some deployments, according to the paper's analysis.

Has NDBI built or sold a nuclear-powered LoRaWAN sensor?

No. The company stated it has not built, tested, certified or commercialised a nuclear-powered LoRaWAN product. The architectures, energy budgets and reporting intervals described in the white paper are conceptual or illustrative unless specifically identified as measured experimental results. NDBI remains a development-stage company and has not commenced commercial production of nuclear diamond batteries.

Why do the LoRaWAN and betavoltaic market forecasts differ so much?

The two figures measure different things. Global Market Insights sized the broader LoRaWAN market at roughly $3.7 billion in 2024, while Mordor Intelligence sized LoRa and LoRaWAN IoT connectivity at approximately $10.71 billion in 2025. Betavoltaic battery forecasts are far smaller: Valuates Reports valued that market at about $3.4 million in 2023. Different definitions and methodologies explain the spread.

Bottom Line

NDBI is selling a compelling maintenance-cost thesis to a 150-million-device ecosystem, but has yet to measure a single watt.
