Research on integrating hydrogen energy storage with solar and wind power for Net-Zero energy buildings

Net Zero Energy Buildings (NZEBs) are evolving as a pillar concept as it fits in with the global Net Zero Energy Target strategy and the decarbonisation strategy of the building sector, which has been developed in response to climate change. The shift from existing building types to Net Zero Energy Buildings is a predominant trend. Net Zero Energy Buildings. This review paper explores the use of solar and wind energy as new sources of energy to generate electricity and hydrogen to store electricity as revolutionary solutions to achieve Net Zero Energy Buildings. It provides insights into the technological advances and challenges associated with hydrogen energy systems, including electrolyser efficiency, storage solution resolution, and fuel cell innovation. In addition, the paper highlights the key role of hydrogen in addressing the intermittency of renewable energy generation and enhancing the resilience and sustainability of Net Zero Energy Buildings systems. The potential for scaling up and commercialising hydrogen storage in the building sector is assessed through a detailed examination of current technologies, performance evaluations, and case studies. Despite facing a number of barriers from technical, economic, and policy perspectives, this paper argues that hydrogen storage can make a significant contribution to the decarbonisation of the built environment through continued technological innovation and framework improvement.
