Product description

The Sunstore Powerpan XLM is a revolutionary green B2B solution that combines solar energy, biochar combustion, and thermal storage to provide off-grid food processing, cooking, and power supply capabilities. This innovative system is designed to address the critical needs of communities in remote areas, schools, refugee camps, and other underserved regions where access to reliable energy sources is limited.

By harnessing the power of the sun through a solar concentrator, the Powerpan XLM can efficiently heat a thermal mass, enabling the slow-cooking of large quantities of food. Additionally, the system is equipped with a water filtration component that ensures clean water supply while simultaneously generating electricity. In situations where solar energy is not available, such as during nighttime or on rainy days, the unit can utilize biochar produced from local agricultural waste to continue cooking and power generation.

Each Powerpan XLM unit has the capacity to produce approximately 200 W of output, significantly reducing the dependency on biomass fuels and leading to a reduction of up to 40 tonnes of CO₂ emissions annually. The system is not only environmentally friendly but also cost-effective, making it a sustainable solution for communities looking to improve their energy access while minimizing their carbon footprint.

Furthermore, Sunstore offers licensing opportunities to manufacturing partners and provides comprehensive monitoring and training for field operations, ensuring the successful deployment and operation of the Powerpan XLM in various settings. By addressing climate, health, and food poverty goals, this innovative solution contributes to building resilience and improving the overall well-being of communities in need.

About the Company

Sunstore Technologies Ltd. is a UK-based clean‑energy social enterprise founded in 2013 in Edinburgh, spun out from the University of Strathclyde. The company develops the Sunstore Powerpan XLM, a hybrid solar-biochar micro‑CHP cooker that simultaneously generates electricity, sterilized water, and hot meals for off-grid communities. The system uses a solar-tracking Fresnel lens and insulated thermal mass to cook up to 2,000 portions per day, purify over 300 litres of water, and generate ~200 W of power—employing biochar for hybrid operation during low solar conditions. The unit supports humanitarian food programs, clean water access, and microgrid energy needs while reducing CO₂ emissions by up to 40 tonnes per year per unit. Sunstore collaborates with NGOs, governments, and research institutions to deploy its technology in Sub-Saharan Africa and India. Backed through Innovate UK Energy Catalyst grants and academic partnerships, Sunstore’s solutions target food equality, clean cooking, and climate resilience.
