An Indian startup has introduced a hydrogen-based cooking system that produces its own fuel from water, offering a different approach to energy use in kitchens. The technology aims to reduce electricity consumption while eliminating the need for conventional fuels.
The system, developed by GreenVize Energy Solutions, uses proton exchange membrane electrolysis to split water into hydrogen and oxygen. The hydrogen is then used immediately as a cooking fuel, while oxygen is released as a byproduct, according to pv magazine.
In its standard configuration, the unit operates without requiring hydrogen storage. Water and electricity are supplied to the device, which generates hydrogen on demand and feeds it directly into the burner. The company says the system can run for up to six hours using around 100 milliliters of water and approximately 1 kWh of electricity.
The concept relies on established electrolysis technology, where an electric current separates water molecules into hydrogen and oxygen using a polymer electrolyte membrane. While the process is well understood, integrating it into a compact, plug-and-play cooking appliance represents a new application.
The company positions the system as an alternative for commercial kitchens and high-demand cooking environments, where flexibility and fuel independence may be beneficial. It also allows optional hydrogen storage, enabling users to generate fuel during off-peak electricity hours or when renewable energy is available.
However, the system’s efficiency and output raise practical considerations. Electrolysis and combustion both involve energy losses, meaning only a portion of the input electricity is converted into usable heat. Estimates suggest that the effective output could be significantly lower than that of conventional electric stoves.
For comparison, standard induction cooktops typically operate at power levels between 1,500 and 2,000 watts. Based on the reported energy input, the hydrogen system would deliver substantially lower heat output, resulting in longer cooking times for common tasks.
The product is priced at approximately ?105,000 for a single-burner unit and ?150,000 for a double-burner version. While the technology may not yet match the performance of existing cooking solutions, it demonstrates a potential pathway for cleaner and more flexible energy use.
Further development and real-world testing will determine whether such systems can scale effectively or compete with established cooking technologies in terms of speed, cost, and efficiency.
