The energy transition alone spans critical minerals, AI data centres, nuclear energy, storage, grids, carbon management, energy security, industrial competitiveness, cooling infrastructure, and about a hundred other rabbit holes. This is no longer a conversation happening inside environmental circles. It is becoming a conversation about how economies, industries, and societies function.
What do uranium stockpiles, critical minerals, battery recycling, low-carbon cement, algae-based materials, data centres, and geopolitical tensions have in common?
More than most people realise.
This article explores why advanced materials may be one of the most overlooked lenses through which to understand climate action, industrial transformation, energy security, circularity, and the industries shaping the next few decades. Through personal observations from eight years in climate and sustainability ecosystems, I unpack how materials sit quietly beneath many of the conversations we treat as separate—and why the future may emerge at the intersections.
Artificial intelligence dominates headlines, investment flows, policy discussions, and boardroom conversations. Yet AI may not be the biggest technology story unfolding today. Beneath the excitement surrounding chatbots, copilots, and foundation models, a far larger infrastructure transition is quietly taking shape. Satellites are observing the planet in real time. Sensors are monitoring everything from power grids to forests. Digital twins are simulating future scenarios before they happen. Robotics are beginning to close the gap between intelligence and action. Cloud infrastructure, semiconductors, cybersecurity systems, digital governance frameworks, and digital public infrastructure are increasingly converging into something much larger than individual industries. Over the past year, while building a sustainability and future technology taxonomy spanning more than 150 domains, I realised I was not looking at separate sectors. I was looking at the emergence of a planetary operating system.
A reflection from inside FICCI’s TANENERGY Summit 2025 on how India is thinking about energy beyond silos.
From nuclear and renewables to AI, grids, and geopolitics, the conversations pointed to systems, not slogans.
And they made one thing clear: Tamil Nadu is becoming central to India’s energy future.
When we talk about climate tech, we often think solar, EVs, or carbon credits.
But the reality? Climate is not one industry — it’s 25 interconnected economies.
And within each of them lie emerging niches: the white spaces where science is turning into startups, and startups are turning into investable futures.
India is the third-largest battery importer — and by 2030, will be sitting atop 2 million tonnes of waste.
At IIT Madras Research Park, a closed-door roundtable asked: will this be a crisis, or a $50B opportunity?
From Battery Passports to second-life reuse, stakeholders confronted the bottlenecks head-on.
This moment could mark the turning point for India’s EV battery circular economy.
India has earned global praise for scaling proven climate-tech models—solar parks, EV fleets, SaaS carbon dashboards. But the frontier isn’t built on speed and scale—it’s about tackling the hardest, high-impact problems.
Globally, startups are pulling CO₂ directly from the sky, insuring farmers with smart contracts, simulating entire climate systems with digital twins, and even betting on fusion to power grids.
India? We’re largely missing in action. India is brilliant at chasing proven models.
But the next trillion-dollar climate startups won’t be EV fleets or SaaS dashboards.
They’ll be parametric insurers, quantum MRV engines, synbio labs, fusion grids, and superconducting VPPs.
If we don’t build them here, we’ll end up importing them—at 10x the cost.
AI, satellites, digital twins, robot dogs, second-life batteries, and carbon vaults — no, this isn’t sci-fi. This is the new frontier of climate resilience.
So… apparently we miss serotonin.
I’ve spent the last few months inside my screen — talking to digital friends, chatting with mental-health AI, wearing reality-cancelling headphones, and doomscrolling like it’s a full-time job.
But lately, I’ve noticed that startups are building for the real world again.
No, not solely in the metaverse. I am not talking about robot dogs. Not even AI Avatars. But actual space. With actual bodies. And actual senses.
→ Brainwave wearables
→Psychedelic walk-through art
→Gloves that let you feel virtual kittens
→Smell-enabled VR fine dining
→Haptic vests that literally make you feel pain while gaming
Simulation is cute. But full-sensory immersion. That's the new chase!
I wrote about the return of physical, sensory-first innovation in my latest article.
Top Emerging & Future Tech that are already here and some evolving fast.
Here are a few wild ones I couldn’t stop thinking about:
- Neuromorphic computing & brain-on-a-chip platforms
- Bioprinting organs in space
- Metamaterials + DNA storage systems
- Smart Dust Monitoring
- Spintronics, Atom circuits
- Ocean energy harvesting
- Space Manufacturing
- Terraforming Mars
- Hypersonic missiles
- Underwater cities
If climate tech is the “how,” emerging tech is the “what next.”
From ocean energy to underwater cities to bioprinted organs in orbit—
these futures aren't sci-fi anymore. They’re shaping climate, conflict & capital.
