Core Products
NuBatt-S1: Betavoltaic Series
Overview: Compact, solid-state nuclear batteries using beta-emitting isotopes for ultra-long-life micro-power applications.
Technical Specifications
| Specification | Value |
|---|---|
| Technology | Solid-state betavoltaic |
| Isotopes | Ni-63 (100-year half-life), Pm-147, H-3 |
| Power Output | nW to ~100 μW continuous |
| Burst Capability | Up to mW with integrated capacitor |
| Voltage | 1-3V (configurable) |
| Operational Life | 30+ years |
| Form Factor | Chip-scale to coin-cell (mm range) |
| Weight | <50g |
| Temperature Range | -40°C to +150°C |
Operating Principle
Beta particles emitted by the radioisotope (typically Ni-63) are captured by a wide bandgap semiconductor (SiC or diamond). The high-energy electrons generate electron-hole pairs, producing electrical current through a mechanism similar to photovoltaics but optimised for particle radiation.
Target Applications
| Application | Use Case | Value Proposition |
|---|---|---|
| IoT Sensors | Remote environmental monitoring | Deploy and forget for up to decades |
| Medical Implants | Pacemakers, neural stimulators | Eliminate battery replacement surgery |
| Memory Backup | SRAM, RTC retention | Continuous power without maintenance |
| COMSEC Devices | Secure communication equipment | Tamper-resistant, long-life power |
| Space Microelectronics | Satellite subsystems | Radiation-tolerant, reliable power |
Development Status
Technology principle validated
Prototype development planned
Target commercial availability: 2027-2028
Strategic Growth Products
NuRTG: Radioisotope Thermoelectric Generator
Overview: Medium to high power systems using thermoelectric conversion of radioisotope decay heat, targeting space missions and remote terrestrial installations.
Technical Specifications
| Specification | Value |
|---|---|
| Technology | Radioisotope thermoelectric generator |
| Power Output | Watts to kilowatts |
| Isotopes | Spent nuclear fuel derivatives, Sr-90, others |
| Operational Life | 10+ years continuous |
| Form Factor | Modular, scalable |
Operating Principle
Unlike nuclear voltaic devices that convert radiation directly to electricity, RTGs convert the heat generated by radioactive decay into electricity using thermoelectric materials. While less efficient than direct conversion, RTGs can achieve higher absolute power levels.
Key Innovation
NuBatt's NuRTG approach focuses on utilising isotopes derived from spent nuclear fuel, rather than relying on the limited global supply of Pu-238 (the traditional RTG fuel). This provides:
- More abundant fuel sources
- Lower fuel costs
- Integration with nuclear waste recycling operations
- Reduced supply chain constraints
Target Applications
| Application | Use Case | Value Proposition |
|---|---|---|
| Space Missions | Deep space probes, planetary landers | No dependency on Pu-238 supply |
| Remote Installations | Arctic/Antarctic research stations | Decades of unattended operation |
| Emergency Power | Critical infrastructure backup | Grid-independent resilience |
| Military Forward Bases | Remote outpost power | Reduced logistics burden |
Development Status
Concept development planned with this funding round
Leverages existing isotope supply chain development
Target prototype: 2028-2029
NuThor: Thorium Molten Salt Reactor
Overview: Compact modular reactor using thorium fuel in a molten salt configuration for industrial and grid-scale power generation. This is positioned as a future opportunity that investors should be aware the Company may pursue.
Technical Specifications

Safety Design
The NuThor incorporates multiple passive safety features:
Freeze Plug: Actively cooled plug melts if power is lost, draining fuel to passively cooled tanks
Negative Temperature Coefficient: Reactor self-regulates as temperature rises
No Pressure Vessel: Molten salt operates at atmospheric pressure
Passive Decay Heat Removal: Natural convection cooling without pumps
Target Applications
| Application | Use Case | Value Proposition |
|---|---|---|
