As the world races towards a sustainable future, innovative solutions that embrace the principles of circular economy are gaining prominence. One such remarkable advancement lies in the utilization of second-life batteries from Nissan Leaf electric vehicles to power Omniflow Smart Lamp Posts. This is the purpose of "Baterias 2030" project in which we enthusiastically participated. This convergence of technology addresses the challenge of battery disposal and revolutionizes how we perceive street lighting, energy storage, and the role of smart grids in our cities.


By repurposing second-life batteries, the Omniflow Smart Lamp Posts showcase the transformative potential of sustainability and circular economy principles. These smart lamp posts harness the power of renewable energy sources such as wind and solar, combined with the increased battery capacity from Nissan Leaf batteries, to create a storage capacity of 6kWh on each pole. Imagine a street lined with 1000 street lights, collectively representing a staggering storage capacity of 6 MWh without utilizing a single square meter of real estate. This extraordinary feat demonstrates the power of repurposing existing resources to meet our energy needs sustainably.

The advantages of this innovative approach are twofold. Firstly, it addresses the challenge of battery disposal and minimizes environmental impact. Instead of discarding used Nissan Leaf batteries, which still have a significant portion of their capacity intact, repurposing them for energy storage extends their lifecycle and reduces waste. This prevents the accumulation of hazardous materials and reduces the demand for new batteries, conserving valuable resources.


Secondly, the utilization of second-life batteries in Omniflow Smart Lamp Posts unlocks the potential for a more intelligent and resilient energy infrastructure. These smart poles become key components of a dynamic smart grid, where, similar to vehicle-to-grid (V2G) systems, they enable intelligent energy management known as infrastructure-to-grid (I2G). The smart poles can store excess energy generated from renewable sources and seamlessly provide it to the grid when demand surges or during power outages. This flexibility allows for optimized energy distribution, reducing strain on the grid and enhancing overall reliability.

"(…) The Smart Grid represents an unprecedented opportunity to move the energy industry into a new era of reliability, availability, and efficiency that will contribute to our economic and environmental health. During the transition period, it will be critical to carry out testing, technology improvements, consumer education, development of standards and regulations, and information sharing between projects to ensure that the benefits we envision from the Smart Grid become a reality.

The benefits associated with the Smart Grid can include:

  • More efficient transmission of electricity

  • Quicker restoration of electricity after power disturbances

  • Reduced operations and management costs for utilities, and ultimately lower power costs for consumers

  • Reduced peak demand, which will also help lower electricity rates

  • Increased integration of large-scale renewable energy systems

  • Better integration of customer-owner power generation systems, including renewable energy systems

  • Improved security (…)" - read more


"When an old EV battery reaches the 4R factory, it is first graded. Sometimes, the battery components are as good as new; they get an "A" grade and can be reused in new high-performance battery units for a new EV. With a "B" grade, the batteries are powerful enough for industrial machineries like forklifts and large stationary energy storage. Deployed in a home or commercial facility, for example, they can capture surplus electricity generated during the daytime by solar panels and then power the building during the night. Even the components of a battery that gets a "C" grade can still be put to use – for example in units that supply backup power when the electric grid fails, say at grocery stores that must have their refrigerators and lights running even during a power outage. The engineers at 4R Energy estimate the recovered batteries have a life span of about 10 to 15 years, dramatically extending the usefulness of EV batteries and reducing their overall carbon footprint." - read more
