The International Solar Alliance (ISA) and the National Dairy Development Board (NDDB) in India are working on an innovative concept, which will bring down the cost of production of green hydrogen and utilise the tonnes of daily cow dung generated on a daily basis.
Officials are thinking of a hybrid model that makes use of solar energy during the day and biogas at night to produce green hydrogen, in a first-of-its-kind model.
The planned new biogas plant will produce electrical energy, which will also help generate thermal energy and will be used for cooling the boilers of the milk plant, and the bio-fertiliser, which will be sold back to the farmers at a designated rate.
“The economics worked out showed that use of a combination of thermal and electrical energy from the biogas led to a savings of Rs 0.40 per litre. Add to that the income generated by selling the bio-fertiliser and it makes sense. Over and above that, the NDDB also plans to encash the carbon credits to gain additional revenue,” said Atul Chaturvedi, secretary, department of animal husbandry and dairying.
The scheme is currently at the planning stage. MNRE will fund the project under its green hydrogen budget.
“If this model works out fine, it will not just be a first-of-its kind model across the world but will create a huge potential for countries like us,” Chaturvedi added.
