MicroPower Global has successfully completed the first real-world field installation of its thermoelectric generator technology integrated with a biomass cooking stove, validating the practical application of waste heat recovery in the clean cooking sector.
The 50W thermoelectric system was integrated into an ESSE-brand biomass cooking stove by Xtralec, a leading provider of clean cooking solutions. The installation demonstrates MicroPower's ability to add electricity generation capability to existing cooking stove platforms, enabling users in off-grid and resource-limited communities to power essential electrical loads while cooking.
"This is a watershed moment for our technology," said a MicroPower spokesperson. "We've moved from laboratory testing to real-world deployment. This installation proves that our thermoelectric modules can be integrated seamlessly into existing cooking appliances, generating meaningful electricity without adding complexity or cost to the end user's experience."
The ESSE cooking stove provided an ideal test platform. The stove's hot plate surface operates at approximately 450°C during normal cooking operations. The thermoelectric modules, integrated into the stove's heat path, create a temperature differential of 250–300°C between the hot plate and the ambient air. This temperature gradient drove continuous electricity generation during stove operation.
"The 50W output we're achieving is transformative for off-grid communities," explained company leadership. "In many parts of the world, biomass cooking is the primary energy source for households. The waste heat from that cooking process – currently lost to the environment – can power LED lighting, charge mobile phones, run small appliances, or provide backup power for critical systems. We're not adding a new energy input. We're capturing energy that would otherwise be wasted."
The global clean cooking sector serves approximately 2.4 billion people who cook on biomass without access to modern electricity. Biomass cookstoves produce significant waste heat – the efficiency of the heat transfer to food is typically 30–50%, with the remaining energy dissipating to the environment. Integrating thermoelectric generators into this workflow adds no operational complexity while creating meaningful energy output.
The Xtralec installation demonstration showed the system powering multiple LED wall lights mounted in the home. The thermoelectric generator continuously powered the lighting system throughout the cooking period, providing dependable electric lighting without batteries or external power connections. Once cooking finished and the stove cooled, power generation ceased naturally.
"This installation validates our core value proposition," noted MicroPower leadership. "Our technology doesn't require new energy sources or new infrastructure. It works with existing thermal processes – cooking stoves, industrial exhausts, waste heat streams that already exist. We simply capture and convert that thermal waste into electricity."
The field installation also provided critical data on thermal stability, module durability, and integration engineering. The thermoelectric modules performed reliably across variable cooking conditions – different fuel loads, ambient temperatures, and cooking durations. The installation demonstrated that thermoelectric generators can be integrated without affecting stove performance or user safety.
"This is momentum building in the right direction," said company representatives. "We've validated the technology through laboratory testing and now through a real-world installation on a commercial cooking stove. Each validation point strengthens our position in the clean cooking, defence, and industrial waste heat recovery markets."
