Gruhas and Rainmatter Climate led a $2.4 million pre-Series A round on behalf of the green energy startup Ossus Biorenewables.
In order to produce 3-5 tons of green hydrogen per day by the end of the year, the company plans to use the funds to accelerate the deployment of Ossus’s OB HydraCel across other industries, such as the refining, foods, brewing, chemicals, and pharmaceuticals sectors.
Ossus uses waste carbon in industrial effluents as the starting material for green hydrogen. It was co-founded in 2017 by Suruchi Rao, Shanta Rao, and Kamar Suhail Basha. The start-up has created the OB HydraCel, an intelligent bioreactor powered by AI that accesses carbon from wastewater from process industries and provides them with on-demand, on-site green hydrogen gas. Utilizing microorganisms obtained directly from effluents as catalysts for the production of green hydrogen forms the basis of Ossus’s core intellectual property.
Ossus claims that its creative efforts support India’s call to produce 5 million metric tonnes of green hydrogen annually domestically without importing foreign-made electrolysers before 2025, and they have already deployed their signature product in Jharkhand for a steel manufacturer.
The startup with headquarters in Bengaluru claims to be collaborating with steel, starch, and energy companies to produce hydrogen gas for less than $1 per kilogram and is looking to expand into other process industries. It competes with companies like Log9 Materials, ReNew Power, Avaada Energy, Cygni Energy, and Sea6 Energy, among others.
