Gruhas and Rainmatter Climate have contributed $ 2.4 million to the pre-Series A round of funding for Bengaluru-based green energy firm Ossus Biorenewables. Ossus Biorenewables is a bio-energy company that uses the chemical content of oil and gas industry effluents as a source of decentralised power. It was founded in 2017 by Suruchi Rao, Shanta Rao, and Kamar Suhail Basha.

In order to produce green hydrogen, the company has created bioreactors that employ the waste carbon found in industrial effluents as the primary raw material. The bioenergy company currently collaborates with steel, starch, and energy companies to create hydrogen gas, and it has expansion aspirations for other process industries as well. At the end of the year, the Bengaluru-based green energy business intends to manufacture three to five tonnes of green hydrogen every day.

Abhijeet Pai, Co-Founder of Gruhas, commented on the development and said that Gruhas's dedication to supporting businesses that have a good impact on the environment while also encouraging young entrepreneurs is reflected in its investment in Ossus Biorenewables.

Aerem, a solartech platform, raised $5 million (Rs 41 crore) in a pre-Series A round last month, with the help of climatetech investor Avaana Capital. The money will be used to increase the company's offering of solartech and financing solutions and to create an ecosystem that unites all of the stakeholders.
