Nuclear energy reimagined: diamonds used to create long-lasting batteries from nuclear waste, marking a significant advancement in the energy sector
In a groundbreaking development, a new type of battery is harnessing the power of nuclear waste to generate sustainable energy. Known as nano-diamond batteries, these innovative power sources use betavoltaic technology to convert the energy from nuclear decay into electricity.
The batteries are designed with ultra-thin layers of single-crystal diamond semiconductors, just microns thick, which act as converters. They utilise radioactive isotopes such as nickel-63, which emit beta particles as they decay. When these particles interact with the diamond semiconductors, they release electrons and generate an electric current without the need for combustion or traditional chemical reactions [1].
The durability, heat resistance, and resistance to damage or explosion of the diamonds make them ideal for these batteries. They can operate from -60 °C to 120 °C and are resistant to severe conditions like punctures or gunshots [1]. The small size of the batteries, with modules smaller than a coin, and their long lifespan—potentially lasting thousands of years as radioactive material decays very slowly—make them a compelling candidate for long-term energy sources [3][4].
Potential applications for these batteries are wide-ranging. They could power consumer electronics such as phones and drones that could operate for decades or even half a century without recharging [1][2]. Medical devices, including implants or sensors needing reliable, maintenance-free power for very long periods, could also benefit from this technology [2]. In the aerospace sector, these batteries could power satellites, space missions, and potentially exploratory probes where solar power is limited or unavailable [2][5]. They could also serve as stationary power sources in remote or harsh environments where replacing batteries is difficult.
The benefits of nano-diamond batteries are numerous. They offer extreme longevity, with batteries that can last from decades to thousands of years, vastly exceeding conventional battery lifetimes [3]. Their safety features include an inert diamond casing that prevents fire, explosion, or chemical hazards even if damaged [1]. They are also stable under temperature extremes, ensuring reliable operation over wide temperature ranges [1].
Moreover, these batteries offer a sustainable way to harness energy from nuclear waste materials instead of storing them as hazardous waste [4]. Their potential miniaturization allows integration into devices where traditional batteries are impractical or add significant weight [1].
The development of nano-diamond batteries is currently in pilot testing stages with prospects for commercial production [1][2][3]. NDB Inc., a San Francisco-based startup, has innovated high-power nano-diamond batteries by merging synthetic diamonds with nanotechnology [6]. Researchers are also working to improve the capture of particles to enhance the energy performance of these batteries [7].
This technology has the potential to revolutionise the energy industry by transforming nuclear waste into sustainable energy. It could have potential applications in space exploration, electric vehicles, or drones. The innovation of diamond batteries was first introduced in 2016 by researchers at Bristol University's Cabot Institute [8].
In a separate development, England has unveiled a reactor that converts sunlight into hydrogen, which could be a game-changer for global energy. This reactor, developed by Oxford PV, uses a perovskite solar cell technology that is more efficient and cost-effective than traditional silicon-based solar panels [9]. The reactor's ability to convert sunlight into hydrogen could lead to a more sustainable energy future, as hydrogen can be stored and used for fuel cells or other applications [9].
These advancements in clean, renewable, and sustainable energy sources are significant steps towards a greener and more sustainable energy lifecycle. They could potentially reduce reliance on fossil fuels and contribute to a future where energy needs are met in a safe, efficient, and environmentally friendly manner.
