In a groundbreaking study, researchers are proposing a transformative business model that could reshape the landscape of renewable energy in Italy. The study, led by Giulio Raimondi from the Department of Civil and Mechanical Engineering at the University of Cassino and Southern Lazio, examines the potential for Renewable Energy Communities (RECs) to harness excess renewable energy and convert it into hydrogen for grid balancing. This innovative approach could significantly enhance the stability and efficiency of the national electric grid as Italy transitions to a more sustainable energy future.
Raimondi emphasizes the urgency of this integration, stating, “As we increase our renewable energy generation, we must also address the challenges of balancing the electric grid. Our research shows that using renewable hydrogen as a storage solution could be a game-changer.” The study highlights the role of the Virtually Aggregated Mixed Unit (UVAM) project, which allows smaller energy producers to access ancillary services markets, making it feasible for RECs to participate actively in grid stabilization.
The proposed model focuses on producing hydrogen from surplus energy generated by local RECs. This hydrogen can then be utilized in various applications, including fuel cells and internal combustion engines, to provide dispatchable energy when needed. However, the research indicates that while the concept is promising, current economic conditions are not favorable for immediate implementation. Raimondi notes that “the return on investment is not yet positive,” but projections for 2035 suggest that with the right conditions—specifically, a community size exceeding 3,000 participants and a photovoltaic capacity of 1.8 kWp per capita—the model could become economically viable.
This research not only underscores the potential of renewable hydrogen in enhancing grid reliability but also points to the commercial opportunities for energy managers and community leaders. By leveraging local renewable resources, RECs can create a self-sustaining energy ecosystem that not only meets local demand but also contributes to national energy goals.
The implications of this study extend beyond Italy. As countries worldwide grapple with the integration of renewable energy into their grids, the lessons learned from the Italian experience could provide valuable insights. With the right policy support and technological advancements, the renewable hydrogen economy could flourish, driving investment and innovation in the energy sector.
The findings of this research are published in ‘e-Prime: Advances in Electrical Engineering, Electronics and Energy’, a journal dedicated to exploring the forefront of energy technology.
