Both statements 2&3 are incorrect.( Vice-versa is True)

• National Thermal Power Corporation Ltd. (NTPC) is a central Public Sector Undertaking (PSU) under the Ministry of Power.
• National Thermal Power Corporation Limited (NTPC) Renewable Energy Ltd (REL) is a 100% subsidiary of NTPC. 
• Recently, NTPC REL signed a Memorandum of Understanding (MoU) with the Union Territory of Ladakh to set up the country’s first Green Hydrogen Mobility project. 
• NTPC REL has planned to ply 5 hydrogen buses, to start with, in the region and the company will be setting up a solar plant and a green hydrogen generation unit in Leh towards this end.
• This will put Leh as the first city in the country to implement a green hydrogen based mobility project. This would be zero emission mobility in true sense.
• NTPC REL will also set up a solar park at Rann of Kutch in Gujarat from where it will also generate green hydrogen on a commercial scale under the Ultra-Mega Renewable Energy Power Parks (UMREPP) scheme.
• NTPC REL will set up a 4.75 gigawatt (GW) renewable energy park at Rann of Kutch in Khavada, Gujarat. This will be India’s largest solar park to be built by the largest power producer of the country.
