Reliance Industries (RIL) will invest in Germany’s NexWafe for 25 million euros (Rs 217 crore), marking its third deal in clean energy. A couple of days ago, RIL inked deals to buy Norwegian-headquartered solar panel maker REC Solar Holdings and India’s Sterling and Wilson Solar.NexWafe develops and produces monocrystalline silicon wafers grown directly from inexpensive raw materials. By going directly from the gas phase to finished wafers, it obviates the need for costly and energy-intensive intermediate steps such as polysilicon production and ingot pulling on which traditional wafer manufacturing relies. The NexWafe transaction is expected to be completed by the end of this month.The investment will be routed through Reliance New Energy Solar and will accelerate product and technology development for NexWafe, including completion of the commercial development of NexWafe’s solar photovoltaics products on prototype lines in Freiburg, RIL said in a late night regulatory filing.Besides its deal with NexWafe, RIL has also signed an arrangement with Denmark’s Stiesdal to manufacture the latter’s hydrogen electrolyzers in India. The technology for hydrogen electrolyzers has the potential to deliver significant cost reduction compared to currently available technologies thereby paving the way for rapid decarbonization, RIL said.The proposed acquisitions are part of RIL’s plans to become net carbon zero by 2035. In June, it had said that it would invest $10 billion in clean energy over three years.NexWafe incorporated on May 18, 2015 had a turnover of 1.41 lakh euros in fiscal 2020.
