Executive Overview
Every year, the editorial and research teams at MIT Technology Review undertake a rigorous, months-long global search to identify the world’s most brilliant young minds. The resulting roster—the prestigious "35 Innovators Under 35"—serves as an intellectual compass for the upcoming decades, highlighting researchers, founders, and inventors whose breakthroughs are poised to reshape industries.
While the list spans multiple critical pillars of modern innovation—ranging from biotech to computing, robotics, and artificial intelligence—the intersection of technology and planetary survival remains one of the most fiercely contested and inventive frontiers. Within the latest cohort, nine exceptional individuals from across the globe have been recognized specifically within the climate and energy category.
When analyzed collectively, these nine innovators do far more than offer isolated solutions to environmental degradation. Instead, they act as a predictive mirror, reflecting the exact state of the global climate technology movement today: where its greatest systemic vulnerabilities lie, how it is aggressively co-opting artificial intelligence, and where the bleeding edge of engineering is heading next.
This report provides a deep-dive analysis into the trends defining this year’s climate and energy laureates, exploring how next-generation materials, ubiquitous artificial intelligence, and radical industrial overhauls are rewriting the playbook for a net-zero future.
Detailed Chronology: The Evolution of the 2026 Climate Cohort
The path to the 2026 climate and energy list began nearly a year prior to publication, with the MIT Technology Review editorial board scouring academic databases, venture capital portfolios, and global research institutions. The selection process prioritized not just theoretical brilliance, but real-world scalability, technological novelty, and immediate applicability to urgent climate bottlenecks.
Phase 1: Identifying the AI-Climate Nexus
As the editorial team categorized the hundreds of global nominations into four main pillars—biotech, climate and energy, computing and robotics, and artificial intelligence—a striking trend immediately emerged: AI is no longer a siloed technology. Rather, it has become the foundational infrastructure underpinning innovation in nearly every other domain, including climate tech.
Throughout the evaluation cycle, judges noted a massive influx of candidates attempting to reconcile the paradox of AI’s surging energy footprint with its immense capacity to solve environmental puzzles. This dual nature of artificial intelligence became a central narrative of the 2026 cohort.
Phase 2: Material Scrutiny and Extraction Breakthroughs
By mid-cycle, the focus of the review shifted toward the impending bottlenecks of the energy transition. Evaluators highlighted a critical blind spot in standard climate discourse: the physical materials required to build a decarbonized society. As global commitments to electric vehicles and grid-scale renewable storage accelerate, the demand for lithium, copper, and rare-earth minerals threatens to trigger severe supply crunches.
The chronological review of candidates in this space revealed a dramatic shift away from traditional, environmentally destructive extraction techniques. Instead, the spotlight turned toward electrochemical processes and hardrock processing startups capable of scaling supply without destroying local ecosystems.
Phase 3: The Long Tail of Industrial Decarbonization
In the final months leading up to the announcement, the editorial lens expanded outward to capture the "less obvious" sectors of society. While energy grids and passenger vehicles regularly dominate climate headlines, the 2026 cohort demonstrated that true net-zero attainment requires a systemic overhaul of heavy industry, chemical manufacturing, packaging, and commercial cooling. The final slate of nine innovators was locked in following intensive peer reviews and technical validations of their underlying research.
Supporting Context & Metrics: Trends Shaping the Climate Landscape
To truly understand the weight of the work being done by the 2026 cohort, one must examine the macro-level data driving these technological interventions.
1. The Paradox of AI’s Energy Footprint and Optimization
Artificial intelligence has rapidly evolved into the dominant technology narrative of the decade. However, the exponential growth of large language models and machine learning infrastructure has created an unprecedented spike in data center power consumption. Major tech companies are now grappling with a surging carbon footprint that threatens corporate and national net-zero targets.
Within this context, innovators like Jae-Won Chung are pioneering crucial corrective measures. Chung has built sophisticated software designed to meticulously measure the exact energy demands of open-source artificial intelligence models. By quantifying power consumption at the algorithmic level, Chung’s work—which builds upon foundational investigations into Big Tech’s energy demands—aims to provide the industry with the diagnostic tools required to mandate energy efficiency standards before computational scaling outpaces global electrical capacity.
Conversely, AI is uniquely equipped to manage complex, multi-variable environmental crises. Jing Wei is currently leveraging machine learning to bridge critical gaps in global pollution tracking. By synthesizing disparate data streams from weather stations, ground sensors, and orbital satellites, Wei’s models can predict and track the dispersion of airborne pollutants with unprecedented spatial and temporal accuracy.
Similarly, urban environments have historically represented a massive blind spot for conventional climate and meteorological models, which struggle to account for the micro-climates created by skyscrapers, asphalt heat sinks, and dense populations. Zhonghua Zheng has successfully developed specialized AI climate models tailored explicitly for urban centers, allowing city planners to simulate heat waves, flood risks, and emissions retention with hyperlocal precision.
2. The Critical Materials Crisis
The transition away from fossil fuels is, at its core, a transition toward mineral-intensive technologies. Lithium-ion batteries remain the linchpin of modern mobility and grid stabilization. According to recent market analysis from firms like Wood Mackenzie, the global economy faces potential lithium and copper shortages as early as the late 2020s.

└── Minimal ecological footprintBrine reservoirs currently represent the cheapest global source of lithium. However, conventional extraction relies on massive evaporation ponds that take many months to yield results while heavily depleting local water tables. Mohammad Alkhadra, co-founder and CEO of the startup Lithios, is addressing this directly by developing electrochemical extraction technologies that pull lithium from brines rapidly and efficiently, drastically cutting down processing times and environmental degradation.
When brine sources prove insufficient, the industry must turn to hardrock ore. While globally abundant, hardrock extraction is historically expensive and energy-intensive. Benjamin Mowbray, co-founder and CTO of Rock Zero, is tackling this economic and environmental hurdle by engineering novel chemical processes designed to extract lithium from hardrock ore cleanly and at a commercially viable scale.
3. Decarbonizing the "Invisible" Sectors
Reaching net-zero emissions requires moving far beyond the low-hanging fruit of passenger EVs and wind turbines. Heavy industry remains stubbornly difficult to decarbonize:
- Steel Production: Accounting for approximately 7% of global greenhouse gas emissions, traditional steelmaking relies on blast furnaces fueled by coking coal. Laureen Meroueh is revolutionizing this sector by developing a novel furnace architecture that simplifies the underlying chemical reduction process, producing cleaner structural steel at a fraction of the cost.
- Plastics and Packaging: The ubiquity of fossil fuel-derived plastics poses a long-term waste and carbon challenge. Joseph Nguthiru is transforming agricultural supply chains by engineering sustainable bioplastic packaging derived entirely from invasive weeds, simultaneously clearing choked waterways and replacing petrochemical polymers.
- Aquaculture Feed: Sustainable food systems require rethinking animal husbandry at every level. Diana Orembe is tackling this by converting urban food waste into nutrient-dense aquaculture feed, closing the loop on local food supply chains and reducing the carbon footprint of farmed fish.
- Next-Generation Refrigeration: Hydrofluorocarbons (HFCs) used in commercial and residential refrigeration are exceptionally potent greenhouse gases, often thousands of times more potent than carbon dioxide trap-for-trap. Jinyoung Seo is developing solid-state refrigerants that eliminate the risk of atmospheric leakage entirely while cutting device energy consumption by up to 20% compared to conventional vapor-compression technology.
Official Statements & Expert Perspectives
The release of the 2026 innovator list has sparked widespread commentary from industrial leaders, academic institutions, and environmental policy experts.
"We are witnessing a fundamental maturation of the climate tech ecosystem," noted a senior researcher involved with the MIT Technology Review editorial board. "For years, the conversation was dominated by high-level macro goals and distant net-zero targets. What this year’s cohort demonstrates is an obsessive focus on the gritty, unglamorous mechanics of the transition—from the exact joules an AI model burns to the chemical bonds in a block of steel."
Industry analysts have similarly underscored the urgency of the material science breakthroughs highlighted in the report.
"You cannot build a wind turbine with good intentions; you need copper, lithium, and rare earths," stated a leading commodities strategist based in London. "Innovators like Alkhadra and Mowbray are not just building startups; they are building the geopolitical shock absorbers for the next century of industrial manufacturing."
Future Outlook: Where Climate Tech is Heading Next
The trajectory of the nine climate and energy laureates points toward a distinct convergence of disciplines over the coming decade.
First, the integration of artificial intelligence into climate science will cease to be experimental and will become standard operating procedure. As models developed by researchers like Zhonghua Zheng and Jing Wei are adopted by municipal governments and environmental agencies, global climate resilience planning will shift from reactive disaster response to predictive, real-time mitigation.
Second, the tightening squeeze on critical raw materials will force a reckoning within the clean energy sector. Venture capital and government subsidies will increasingly flow away from speculative software plays and toward hard tech, chemical engineering, and advanced metallurgy. The success of startups like Lithios and Rock Zero will serve as the litmus test for whether the clean energy supply chain can scale fast enough to meet global climate mandates.
Finally, the decentralization of climate innovation—exemplified by novel bioplastics from invasive weeds and solid-state cooling materials—signals that the path to net-zero will be built upon thousands of localized, specialized interventions rather than a single silver bullet.
As these young innovators transition from academic labs and early-stage incubators to commercial deployment, their work will define whether the global economy can successfully bridge the gap between climate ambition and physical reality.
