Achieving sustainability through V2G technology optimization. EROI improvement model for batteries as a distributed source of energy

      Аннотация: Energy management can be seen as important instruments for recognizing existing economic energy efficiency potentials. Significant energy-efficiency improvement opportunities exist in the industrial sector, many of which are cost-effective. Specifically in the battery industry, which is becoming a sector with significant impact on the global economy, as they have potential to provide access to renewable energy sources and reduce GHG emissions. This project aims to optimize batteries by improving their efficiency calculated by the EROI (Energy Returned on Energy Invested) value. According to the calculations developed in this study, the most efficient and sustainable way for using batteries for storing energy is using them as distributed sources of energy through Battery Electric Vehicles with a Vehicle to Grid configuration. In order to reach this level of efficiency several techniques have been considered such as the expansion of the battery lifespan through optimum battery discharge or improvement of the energy management strategies along the supply chain. The positive impact of the V2G configurations as a sustainable energy strategy has been well demonstrated in the literature.
