The National Institute of Solar Energy (NISE), an autonomous institute under the Ministry of New and Renewable Energy (MNRE) in India, has released an expression of interest (EoI) for developing the scope and drafting the tender terms and conditions for the operation and maintenance (O&M) of its green hydrogen facility located at the NISE Hydrogen Facility in Gurugram, Haryana. The objective of this tender is to seek assistance in defining a robust and technically sound tender to identify a future O&M service provider for the solar-powered green hydrogen generation, storage, and refueling facility. The scope of work includes proposing detailed inputs for an appropriate O&M model, advising on cost structures, risk-sharing mechanisms, and eligibility criteria. The project involves a green hydrogen facility with a production capacity of 15 Nm³/hr and hydrogen storage of 60 kg at 495 bar, running on a dedicated 120 kWp rooftop solar system. The facility utilizes technologies like alkaline electrolyzers and high-pressure compressors. Bidders are required to present a cost structure encompassing both fixed and variable O&M costs, along with their experience in handling similar systems. Moreover, the initiative is in line with India's efforts to promote green hydrogen, as seen through the introduction of the Green Hydrogen Certification Scheme to encourage sustainable hydrogen production practices.
