Photovoltaic modules and batteries in thermoelectric hybridization
A hybrid solution that integrates thermoelectric and solar energy to lower generation costs, improve system inclusion, and accelerate the energy transition

 

Three million people connected to 251 isolated systems in the Amazon currently consume approximately R$ 13 billion/year in diesel, resulting in greenhouse gas emissions 1,515% above the national grid average. At the same time, eliminating the electricity access gap for more than 1 million disconnected people in the region would cost approximately R$ 14 billion.

 

Urgent action is needed to replace fossil fuels with renewable energy that delivers both emissions reductions and affordability. In this context, there is a promising solution that hybridizes diesel plants with photovoltaic solar and battery systems, cutting generation costs while supporting decarbonization, universal access, uninterrupted supply, and electricity quality all with low CAPEX.

​

...What does it take to implement a hybrid system with these benefits?
A management system for hybridizing electric generators coupled to small-scale combustion engines. The main technical challenge lies in scaling the solution up to a demonstration plant, particularly if deployed in the Amazon, where additional logistical hurdles exist. At this stage, it is also essential to evaluate alternatives that enhance the operational and environmental performance of diesel thermoelectric plants.
