Acceleron Fusion is developing muon-catalyzed fusion reactor, using subatomic particles known as muons to lower the heat and pressure required for cold fusion reactions to take place. The startup is hoping that by raising the pressure of the hydrogen isotope mix, and maybe the temperature, it’ll be able to reduce the rate at which muons stick to alpha particles. The hope is to keep enough muons in the mix to catalyze more fusion reactions, ideally enough more that they’ll offset the amount of power required to generate the muons.

Prometheus develops micro fusion technology. Its reactor consists of one or more reaction chambers where electrodes, actuators, and fluid intake and discharge devices are installed. It is modular and scalable, allowing configuration in the most suitable dimensions for each application. The operating parameters are managed and monitored in real time. The reaction is triggered using a saline solution and readily available materials. The company says it's suitable for applications ranging from domestic and mobility uses to large-scale industrial plants.

Clean Planet is developing "light hydrogen nuclear energy" technology known as QHe. Originally developed in Tohoku University it uses hydrogen quantum diffusion to generate heat. The diffusion is induced by heating a small amount of hydrogen saturated in nano-sized nickel-based composite material. QHe can provide industrial-scale heat up to 1,000°C. The technology operates with nano-sized nickel- based composite material and a small amount of hydrogen. Clean Planet is currently engineering QHe-powered heat modules that can provide energy to the industrial, commercial, transportation, and residential sectors.

ENG8 is a company that has developed a catalysed fusion (LENR), renewable energy technology called the EnergiCell. The fuel source is the water molecule where the ionised H2O molecule supplies the hydrogen ions needed for catalysed fusion. A primary energy release mechanism is a catalysed fusion process where protons and neutrons are fused into atomic nuclei. Energy is released in the form of electricity and heat and with modifications can produce chemical energy in the form of hydrogen and oxygen. The company says, it is able to produce more electrical and/or thermal energy than the system requires to power itself.

Husk is creating solar microgrids in rural Africa regions (primarily in Nigeria, expanding to the Democratic Republic of the Congo, Zambia, and Madagascar). The company has developed an integrated AI-based platform that goes beyond simply selling electricity to include the sale and financing of energy-efficient appliances, comprehensive solutions for rooftop solar power systems on commercial and industrial properties, and a wide range of low-carbon and climate-resilient energy services, including e-mobility, agro-processing, and cold storage. The company says this approach is gradually becoming more intelligent and automated through the use of artificial intelligence and the Internet of Things.

Hylenr develops Low Energy Nuclear Reactor (LENR, aka cold fusion) that enables nuclear interactions within engineered metal lattices that operate near controlled conditions and by using accessible materials. It works by loading hydrogen isotopes into a solid metal lattice and using targeted excitation to trigger fusion reactions at manageable scales. Energy is generated via elemental transmutation - fusion and fission of host material. The reactor emits no radiation - just heat.

Transmutex develops designs and software for an accelerator-powered technology that turns existing nuclear waste into clean energy and produces radioisotopes for medical and industrial applications. The technology is offered to nuclear power plant operators and includes full support from procurement to maintenance. The main idea is mixing thorium with nuclear waste and transforming it into energy (heat or as electricity) and more short-lived elements that will decay within 300 years - less time than it takes for a plastic bottle or a cigarette butt to degrade in the ocean.
