“The National Technology Transfer Pole for Sustainability, Tech4Planet, was created to support the growth of the most promising technologies born within Italian research centers and bring them to the market. Sinergy Flow is a particularly significant startup in this sense because it operates in the segment of energy storage, which is one of the fundamental building blocks for achieving decarbonization goals, and it does so with an outstanding team, with a great propensity for business development and internationalization”
