Patna: Construction engineering company Ashoka Buildcon plans to invest Rs 9,000 crore in setting up a green hydrogen plant in Bihar, its COO (renewable energy) Mayank Sharma said on Friday. The company signed an MoU with the state govt, committing to investing in the plant. The Maharashtra-based firm is in highway construction, power distribution and solar projects. Sharma said the company would set up a 1,250MW solar project and use the clean electricity to produce green hydrogen by splitting water. “The first phase of the plant is being planned at Begusarai (in Bihar),” he said. Green hydrogen is the cleanest known source of energy, which produces just water from being burnt. Sharma said the first phase of the project will take 1.5-2 years to commission from the date of receiving all clearances. The second phase will follow thereafter.
