Coming up, tomorrow, a conversation with Apoorv Shaligram, founder and CEO at e-TRNL Energy in Bengaluru, where he and fellow founder Uttam Sen are innovating the next generation battery cell architectures and advanced manufacturing processes.
Apoorv and Uttam recently announced raising Rs. 27.4 crore (About $3 million) in seed funding, led by IAN Group (Indian Angel Network), with Navam Capital, and existing investors Speciale Invest, Micelio and others also joining in. You can catch the full conversation right here, or wherever you get your podcasts. Here’s a 60-second preview with Apoorv talking about how the deep tech landscape in India is undergoing a government-led transformation.
So, this morning, I drove up to the new office that Apoorv Shaligram and Uttam Kumar Sen and their team at e-TRNL Energy have set up – still being given some final touches before a formal inauguration soon.
Sat down with Apoorv to record the next episode of Conversations. And it’s always an awesome experience to do this in-person, in whatever conditions present themselves onsite, in terms of light and sound. (I did carry two Neever panels and my DJI wireless mics, and more on that in a separate note.)
I’ve had the privilege of being acquainted with this deep-tech entrepreneur duo – IIT Bombay alumni – almost from the time they set up e-TRNL and, in one early conversation a few years ago, they’d tried to help me understand the tech innovations they had in mind.
Today, we caught up in the context of their recent announcement of having raised Rs. 27.4 crore (About $3 million) in seed funding, led by IAN Group (Indian Angel Network), with Navam Capital, and existing investors Speciale Invest, Micelio and others also joining in.
We also spoke about the funding experience — what’s changed, what worked, best practices and so on. Catch all of that in the full conversation right here, or wherever you get your podcast, on Friday, Feb. 20.
Here’s a 90-second preview, with Apoorv explaining 3DEA, their 3D electrodes architecture.
By the way, I also just started a WhatsApp channel for anyone who prefers to keep track of their deep tech news and views that way.
MEINE Electric is an Indian deep-tech startup in Chennai, developing iron-air battery systems designed for long-duration energy storage of 16 to 24 hours. Founders Priyansh Mohan and Stuti Kakar hope that these batteries will help accelerate India’s transition to net zero carbon emissions.
They use a process of controlled reversible rusting to create a cost-effective, sustainable alternative to lithium-ion batteries and pumped hydro storage. By utilizing abundant materials like iron, air, and water, they aim to provide 100 percent renewable energy reliability for energy-intensive industries such as mining and data centres.
Their proprietary innovations include fast-charging capabilities and a unique gas-diffusion electrode that is compatible with high-volume manufacturing. The venture has secured pre-seed funding and plans to showcase its first product pilot later this year. Ultimately, they envision building a renewable energy ecosystem to stabilize the grid as global power demands shift toward green sources.
You can catch the full conversation right here, or wherever you get your podcasts. Here’s a quick point on how the founders are innovating to develop their product for scale.
In this episode, I’m joined by Priyansh Mohan and Stuti Kakkar, school friends turned co-founders at MEINE Electric, to talk about their innovations in developing iron-air battery energy storage systems (BESS) for long duration energy storage (LDES).
Renewable energy in India faces a fundamental problem of timing. Solar panels and wind turbines produce electricity when nature dictates, not necessarily when industrial factories require it. For the green transition to succeed, power must be stored for the long hours when the sun is down or the wind is still. While lithium-ion batteries serve short durations, they remain too costly for day-long storage.
Priyansh and Stuti are innovating in the area of controlled, reversible rusting, with the aim of providing energy storage for 16 to 24 hours at prices lower than with current options such as pumped hydro storage and of course lithium-ion batteries. Their approach uses materials abundantly available — iron, air, and water — to avoid the complicated supply chains associated with rarer metals.
“At the core of it, it’s just reversible rusting. We all know that iron rusts — it’s not a reaction that’s unknown to humanity — but to do it in a controlled fashion at a greater efficiency so it acts as a battery is where our innovation and the whole magic lies.”

In this episode, we get a peek into the engineering innovations behind their technology and some of the challenges that remain in the way of building deep tech companies from India. Backed by Rebalance, Antler, Venture Catalysts, gradCapital, and Anna Incubator, Stuti and Priyansh have recently raised a pre-seed investment in their venture.
They expect to showcase a pilot-ready version of their first product as early as later this year.

Generated image to illustrate deep tech startups. India has modified its policies to provide longer term support for such startups.
India has rewritten the rulebook for startups in the country, carving out a separate deep‑tech category with a longer recognition window and higher turnover ceiling in a move aimed at research‑heavy, capital‑intensive ventures.
In a gazette notification dated February 4, the Department for Promotion of Industry and Internal Trade (DPIIT) said deep‑tech startups recognised under the Startup India framework will be eligible for benefits for up to 20 years from incorporation, twice the 10‑year limit that continues to apply to other startups. The annual turnover cap for such entities has been set at Rs. 300 crore.
The notification replaces the 2019 definition of a startup and, for the first time, provides a formal policy definition of what counts as “deep tech”. DPIIT describes deep‑tech startups as entities building solutions rooted in new scientific or engineering knowledge, with high research‑and‑development intensity, ownership or creation of novel intellectual property, long development timelines and substantial technical uncertainty.
Sectors explicitly cited in government and industry commentary include artificial intelligence and associated infrastructure, semiconductors, space, biotechnology, new materials, energy and quantum technologies.
Governments from Washington to Brussels and Beijing have been racing to update startup and industrial‑policy regimes to court deep‑tech founders, whose capital needs and time horizons sit awkwardly with standard venture‑capital cycles. Europe has launched targeted deep‑tech funds, while America has used instruments such as the CHIPS and Science Act to back strategic technologies; China continues to marshal state support for advanced manufacturing and hard tech.
India has recently launched a research, development and innovation fund of Rs. 100,000 crore.
The move to extend recognition to 20 years and raise the turnover threshold is cast in Delhi as an attempt to signal that the government is prepared to match the longer gestation of frontier technologies with a more patient policy framework at the highest levels.
“This is a decisive and forward‑looking move by the government. By formally recognising deep‑tech startups and giving them a longer runway, India is aligning policy with the realities of science‑led innovation,” Vishesh Rajaram, founding partner at the well know deep tech VC firm Speciale Invest, said in an emailed statement.
“It sends a clear signal that the country is serious about building IP‑driven deep‑tech companies from India for the world—and gives founders and investors the confidence to commit long‑term capital to that journey,” Rajaram added.
Beyond timelines and turnover, the revised framework also tweaks the scope of who can qualify as a startup under the scheme. Cooperative societies are now eligible alongside companies and LLPs, broadening access to benefits, while regular startups retain a 10‑year recognition window and see their turnover cap raised from Rs. 100 crore to Rs. 200 crore.
DPIIT will continue to process applications through its portal, but deep‑tech ventures must furnish additional evidence of scientific novelty, R&D spend and IP creation to qualify for the extended treatment.
“India just gave deep tech a real policy home and BYT Capital welcomes DPIIT’s new Deep Tech Startup definition (4 Feb 2026), a timely step that aligns policy with the realities of frontier innovation,” Amit Chand, founder of BYT Capital, an early stage deep tech VC firm in Bengaluru, said in an emailed statement.
“By extending startup recognition for eligible deep‑tech ventures to 20 years and raising the turnover threshold to Rs. 300 crore, this policy doesn’t just add a label, it improves time horizons, capital efficiency, and investability for deep‑tech in India,” Chand said.
He added: “This is a meaningful step toward making India more ‘fundable’ for frontier innovation because policy timelines now look closer to deep‑tech timelines”.
