1. Concept of open-source CSP co-generation unit for households
2. challenge • Renewable energy is at the core of sustainable development • Not everyone can use renewables due to tecnological, financial and regulatory barriers • Electricity grids are often restrictive • Existing renewable energy soultions are often too expensive
3. our solution • Open-source co-generation Open-source co-generation solar powerplant artist rendering, based on concept drawings
4. core components
5. how it works 1) Fresnel lens concnetrator focuses solar rays onto the heat receiver. Temperatures at the focal area may exceed 800° C. Solar tracker governs a system of stepper motors which position concentrator precisely to get maximum amount of solar rays 2) Heat reciever transfers heat to salt solution which circulates to the high- temperature storage. At this stage salt solution is used, as it can store more thermal energy at higher temperature than water. 3) High-temperature heat storage is an extremely well insulated tank which purpose it to store extremely hot salt solution with minimal heat loss. Such storage provides opportunity to generate electricity and heat whenever user needs it, independent of the rapidly changing. Industrial variants of heat storage can store heat at around 800° C up to 5 months. In our case, we plan to be able to store that temperature for 10 days. 4) Through a system of heat exchangers the thermal energy from salt solution in heat storage is used for turning water into pressurized vapor which moves steam turbine. We plan to re-use automotive steam turbines, commonly found in many vehicles with internal combustion engines. Heat recuperation system condenses the used steam back into the water 5) Steam turbine is connected to AC generator which produces electricity for the users
6. advantages The powerplant we are designing will have a series of advantages: – Completely open-source. Available for commercial or non- commercial usage. – Electic power output — 3-10 kW (depending on number of turbines/generator used) – Easy-to-replace mirror segments – Can be built and assembled in non-industrial settings – Modular design – Delivers power when needed independent of weather – Does not require grid – Scalable – Allows for maximum usage of local materials
