In India, well over a million people are estimated to die every year due to air pollution, making it one of India’s most acute environmental problems. In particular, pollution from agricultural residue burning can contribute to anywhere up to half the pollutants in the air at specific times of the year. Farmers have short windows of time between their two crops cycles to remove residues from the previous harvest, and often resort to burning it. But what if this so-called stubble could be quickly processed instead into a fuel or other commodity? That is the challenge taken up by Vidyut Mohan and the team at Takachar. In this episode, we speak to Vidyut about their affordable device for thermally treating the stubble on smallholder farms. He talks about moving to Europe and how a chance meeting with a fellow researcher in the United States eventually led to the manufacturing plant they have now established in Bengaluru. We get into what they have learned from on-the-ground projects in Delhi and Tamil Nadu, as well as how an unexpected development in the global climate discussion – mushrooming appetite for low-costs carbon removal solutions – has recently transformed the fundraising outlook for Takachar.

In climate discussions, India’s agricultural sector is often highlighted in terms of the likely climate impacts to the sector – due to heat waves and floods – but it is also a significant consumer of fossil fuels. Around 15% of India’s overall electricity demand comes from agriculture. Structural problems, including small land-holdings and a lack of adequate returns, make it hard to shift to cleaner sources of energy, even in cases where solar power could free up resources and improve livelihoods. Through Khetwork’s groundbreaking work on high-efficiency irrigation pumps, Victor Lesniewski is working to decarbonise agricultural energy use in the agriculture sector and also make farmers more productive to increase their revenues through the year. He and his co-founder Katie Taylor (who we also talk to in this episode about gender- and culture-related challenges for clean energy entrepreneurs) produce solar pump systems for smallholders that target the dry-season, when kerosene pumps are most costly. They share what they have learned about relocating a technology solution from Massachusetts to Maharashtra, why efficiency is key to reducing capital costs, and how to bring sceptical customers on board. When this conversation was recorded in May 2022 they had reached a production capacity of 120 pumps per week, and looking at financing options for further scale-up in an environment of rising input costs.

The importance of energy efficiency cannot be overstated. IEA’s Executive Director Dr. Fatih Birol frequently refers to energy efficiency as the “first fuel”, since it represents the cleanest and often, the cheapest way to meet our energy needs. As per IEA’s scenarios, after renewables, energy efficiency offers the second greatest potential to reduce carbon emissions in our economies. If India were to pursue its pathway to net zero emissions by 2070, nearly one third of the emissions avoided by 2040 compared to the current pathway could come from energy efficiency alone. To discuss one aspect of energy efficiency – that related to residential energy consumption – we speak with Soumya Bhattacharya, the Co-founder and CFO of SustLabs, an energy efficiency solutions provider based in Mumbai since 2016. We focus in particular on SustLabs’ Ohm Assistant, which is a device that clips onto the cables near your residential electricity meter and constantly reads the frequencies of electricity being drawn into a home with a very high level of precision. This enables consumers access information they need most to make decisions that help improve energy efficiency at home. Our conversation with Soumya focuses on a range of issues including the innovation challenge that they undertook, the learning curve that their consumers have to deal with, the scale of SustLabs’ operations currently, and their ambitions for the future.

In 2019, India achieved a historic landmark of reaching near-universal household connectivity to electricity, meaning that over 900 million citizens have gained an electric connection to their households in the past two decades. However, power outages continue in large parts of the country. In some areas, such outages can last for several hours on a daily basis. Deploying renewable energy quickly in these communities would help address a range of issues, including air pollution from the use of backup generators as well as energy inequity and female participation in the workforce. Savitha Sridharan founded Orora Global in 2014 as a social enterprise with a technological solution: the Orora PowerHub. This product can combines solar photovoltaics and batteries in different configurations to in a couple of innovative ways to meet the specific needs of low-income communities in India. Today, Orora is helping to cheaply power sewing machines, fridges and lighting to a path out of a cycle of poverty. This conversation, recorded in early March 2022, covers Savitha’s passions for engineering, social impact and running, as well as her successes in raising skills and capital in both India and the United States.

Over the next two decades, India’s vehicle stock is set to double to over 550 million. Along with it, oil demand from these vehicles, and carbon emissions are also expected to double. In India, two and three wheelers are routinely identified as having the highest potential to be a frontrunner in vehicle electrification, but commercial fleet operated vehicles spend most of the day in motion. Slim margins mean that drivers cannot afford to spend too much time charging during the day. Ashwin Shankar, the Founder and CEO of BatteryPool, provides battery swapping solutions for EV fleets. In our interview, he explains how he identified vehicle electrification as a major pollution-tackling opportunity for India’s cost-conscious society, and how fast the landscape has changed over the past five years. Given the challenges of managing capital risk in an environment with hardware inventory and rapidly evolving battery technology, Ashwin tells us how BatteryPool has pivoted from vehicle ownership to selling to fleet operators. This episode was recorded in December 2021.
