Webinar Series – Episode 3 | Presented by Scott Edwards

Persistent, reliable power remains one of the greatest challenges facing modern Defence and space capability.

In the latest instalment of the entX webinar series, Chief Operating Officer, Scott Edwards, outlined how entX is developing next generation betavoltaic power technology through its GenX platform to address this growing capability gap.

As autonomous systems become increasingly important across Defence, intelligence and aerospace applications, endurance has become a critical operational challenge. Systems operating in remote, contested and extreme environments require power solutions capable of functioning independently for extended periods without resupply or recovery.

While batteries and solar technologies remain important, both face limitations in harsh environments, prolonged darkness, subsea conditions and covert operations.

“Defence agencies are actively exploring betavoltaics to address this mission-critical capability gap, enabling long-life, low-maintenance power for persistent, distributed systems,” Scott Edwards said.

What is GenX?

Often referred to as a “nuclear battery,” betavoltaics are compact nuclear generators that convert energy from radioisotopes into electricity.

When paired with the right radioisotopes, these systems can potentially generate power continuously for years or even decades, making them suited to extreme environments including space missions, undersea operations and ultra-cold conditions.

While betavoltaic technology has existed for decades, historical systems have operated at very low power outputs. GenX has been developed specifically to overcome this limitation by targeting significantly higher power density and enabling new Defence and aerospace applications.

The GenX Advantage

GenX is a thin-film composite betavoltaic power platform designed around scalability, manufacturability and high-power performance.

Its architecture replaces traditional wafer-based semiconductor designs with ultra-thin, stackable inorganic semiconductor cells that can be interconnected into scalable modules.

Scalable Manufacturing and Defence Applications

entX has commissioned a prototype manufacturing facility within its specialised high-radiation clean rooms and is currently operating at Technology Readiness Level 6 (TRL6), with product and process validation underway.

The company is actively engaging with customers and integration partners to tailor GenX for real-world applications including:

• Autonomous battlespace sensing

• Unattended ground sensors

• Undersea surveillance systems

• Covert monitoring devices

Mission-ready GenX prototypes are targeted for field deployment this year, with the United States remaining a key strategic market.

Opening New Procurement Pathways

For investors, GenX represents more than an advanced energy platform.

The technology opens access to multi-million-dollar procurement opportunities across Defence, intelligence, aerospace and space sectors, where demand for autonomous and persistent capability systems continues to grow.
