![]() ![]() The technology used a solvent/molecule called APBS (amin-promoted buffer salt), which causes less corrosion on the plant surfaces. “We didn’t hit it on one night, but consistently over two years," says Sharma, 31. The partners started testing on computer simulations and by 2009 end, they had developed a new molecule and associated technology which could dramatically reduce cost in both new and old plants. But the first-hand learning from customers was different-carbon capture was too expensive, too corrosive and came with the risk of some chemicals ending up in the atmosphere as well. They got a few power plants interested in their idea, collated the relevant data and compiled the results. ![]() On return, he used the three months’ learnings to choose this subject for his master’s thesis.Īfter leaving college, the two men started a consultancy. This was 2008, and Europe’s approach to reducing the carbon footprint was different to India’s. When in his third year of engineering at IIT, Bumb got selected for a programme in a university in Italy where he learnt about carbon capture. Prateek Bumb, CTO and co-founder at Carbon Clean Solutions. This project came together over eight years after the two college mates and hostel roommates decided to push the boundaries of technology just a bit further. The company’s first plant, in partnership with Tuticorin Alkali Chemicals and Fertilizers, came up in Tamil Nadu in October 2016 and converts carbon dioxide from its coal-fired boiler into soda ash. “Globally, and in India, this is a unique firm that has taken a nascent technology to be applied commercially," says Amit Kumar, senior director-social transformation, The Energy and Resources Institute (TERI), a think tank working on sustainable development in India. The best part is they have reduced the cost of capture and it’s efficiently working around the globe," says Vikram Vishal, a geologist and assistant professor at IIT-Bombay’s department of earth sciences. “They (CCSL) have their own patented technology for the whole process of capture and the solvent they use for scrubbing carbon dioxide out is unique. They are targeting $15 a ton and if “we get to $10, we would be close to European carbon credit scheme," says Sharma. CCSL can capture carbon dioxide at the cost of $30 a ton-other available technology does it for $60-90 a ton. The CCSL technology claims to not only help capture carbon at rates much lower than market standards, but also allows the user to sell that carbon. The main contributor to this is burning of fossil fuels by industries.īut industry and profit and a need for energy have always won over conservation, which CCSL tries to overcome by providing the means to incentivize carbon capture. Global warming-an increase in the earth’s average surface temperature-is caused by greenhouse gases like carbon dioxide and methane. As carbon emissions have increased over the years, warming the earth, leaders, environmentalists and climate change experts have spoken about the need to reduce carbon emissions to preserve the planet’s future. ![]()
