India’s Energy Revolution: 7 Powerful Technologies Driving the Net-Zero Dream

To achieve its 2070 net-zero target, India is pursuing a multi-technology strategy, blending nuclear innovation with diverse electric mobility solutions. Principal Scientific Advisor Ajay Kumar Sood emphasizes integrating conventional nuclear reactors and small modular reactors (SMRs)—compact units ideal for powering data centers or industries needing uninterrupted clean energy—despite current cost challenges. The recent U.S. approval for Holtec International to share SMR tech with Indian firms accelerates this vision.

Simultaneously, India’s EV roadmap extends beyond lithium batteries, exploring hydrogen fuel cells, sodium-ion alternatives, and futuristic solid-state batteries to reduce import reliance and address varied needs. This dual focus on nuclear scalability and EV innovation underscores a pragmatic approach: avoiding over-dependence on single technologies while fostering R&D ecosystems for long-term energy security.

By balancing immediate adoption with cutting-edge research, India aims to tailor solutions to its vast geography and economy, ensuring a resilient, low-carbon transition. 

India’s Energy Revolution: 7 Powerful Technologies Driving the Net-Zero Dream

As India races toward its 2070 net-zero carbon target, the nation’s scientific leadership is advocating a pragmatic yet visionary approach: keep all technological doors open. From next-gen nuclear reactors to diverse electric vehicle (EV) innovations, the emphasis is on flexibility, scalability, and strategic R&D to secure energy independence while combating climate change.  

Nuclear Energy: Small Reactors, Big Potential

The recent U.S. greenlight for Holtec International to share small modular reactor (SMR) technology with Indian firms marks a pivotal shift. Principal Scientific Advisor Ajay Kumar Sood underscores nuclear energy as “inevitable” in India’s energy mix. Unlike traditional reactors, SMRs—compact, factory-built units—offer niche advantages. For instance, they could power energy-hungry data centers with reliable, round-the-clock clean electricity, even if costs remain higher than conventional sources.  

“In the energy transition, it’s not about choosing either SMRs or conventional reactors—it’s both,” Sood explains. The U.S. approval, tied to strict non-proliferation safeguards, unlocks collaboration with Indian giants like L&T and Tata, accelerating homegrown SMR development. This aligns with India’s broader nuclear strategy, which includes scaling up its 500 MW reactor fleet and exploring advanced designs to meet rising demand without fossil fuels.

EVs Beyond Batteries: Fuel Cells, Sodium-Ion, and Solid-State Futures

While battery EVs dominate headlines, Sood urges a broader vision. “Lithium isn’t the finale,” he says, pointing to alternatives like hydrogen fuel cells and hybrid systems. Green hydrogen, produced via renewable energy, could power fuel cell vehicles, offering long-range and quick refueling—a boon for India’s freight and public transit sectors.

Meanwhile, battery R&D is exploring sodium-ion tech, which avoids scarce lithium, and solid-state batteries promising higher safety and energy density. Though still in development, solid-state variants could revolutionize EVs by 2030. “Our R&D roadmap ensures we’re not import-dependent in five years,” Sood notes, highlighting the Anusandhan National Research Foundation’s inaugural mission on EV innovation.

Strategic Diversification: Why ‘One-Size-Fits-All’ Fails India

India’s vast geography and economy demand tailored solutions. A remote industrial hub might prioritize SMRs for stable power, while a megacity could leverage solar-storage hybrids. Similarly, electric two-wheelers may thrive on sodium-ion batteries, while hydrogen trucks ply highways.

Sood’s mantra—“multiple technologies, not replacements”—reflects this pragmatism. For instance, SMRs, while costly today, could serve critical infrastructure, sparing the grid from data centers’ massive loads. Similarly, investing in solid-state batteries today prepares India for tomorrow’s EV markets.

The Road Ahead: Collaboration, R&D, and Policy Agility

Achieving this multi-tech vision requires policy agility and global partnerships. The Holtec deal exemplifies how international collaboration can bypass past nuclear trade barriers. Domestically, initiatives like production-linked incentives for EVs and green hydrogen missions must balance immediate adoption with long-term R&D.

Critically, India’s strategy avoids locking into single technologies, ensuring adaptability as innovations emerge. Whether in nuclear or EVs, the focus is on building ecosystems—skilled workforces, supply chains, and regulatory frameworks—that empower diverse solutions.

Conclusion 

India’s energy transition isn’t a sprint but a marathon with multiple lanes. By embracing SMRs, next-gen nuclear, and a spectrum of EV technologies, the nation is hedging against uncertainties while fostering homegrown innovation. As Sood asserts, the goal isn’t to pick winners but to cultivate a portfolio where each technology thrives in its niche—powering a cleaner, more resilient future.
