This project aimed to develop an energy storage system charged by a steam turbine, designed to supply electricity both to a sulfur refinery in Ashdod and the national electricity grid. The system is intended to store excess energy during periods of high electricity prices, and/or to provide power to the factory when it is not cost-effective to sell electricity back to the grid. The challenge was in optimizing energy storage and retrieval processes, to ensure a reliable and cost-effective energy supply. The project produced an efficient energy management system, reducing operational costs for the factory while also contributing energy to the electricity grid.

Generating sustainable, environmentally friendly energy is a vital challenge today. This project designed a green energy harvesting system utilizing the piezoelectric effect, which converted mechanical energy from foot traffic in public spaces into electrical power. An innovative prototype was designed and constructed, integrating piezoelectric plates, insulating materials, and robust anchoring solutions into practical pavement tiles. The harvested electrical energy was stored in batteries or advanced storage systems for later use. The goal of the project was to achieve results consistent with those reported in related studies, with significant improvements if possible. The system demonstrated cost-effective reliability and efficiency, offering lower production and maintenance costs compared to traditional energy generation methods.
