MacroVoices #548 Dr. Carly Anderson: Emerging Energy Technologies Roundup

In this MacroVoices episode from August 2026, venture capitalist and energy expert Dr. Carly Anderson discusses the current state and future prospects of nuclear energy technologies. The conversation covers two main areas: nuclear fission and nuclear fusion.

On the fission side, Anderson highlights several key developments: the importance of hyperscalers and data center companies in creating demand through 20-year PPAs at $100/MWh (which didn't exist until recently), the potential of small modular reactors (SMRs) that can be deployed in under two years compared to traditional plants taking a decade, and various strategies to accelerate deployment including power uprates at existing plants and reactor restarts. She emphasizes that mass manufacturing of reactor components—not just factory assembly but true mass production with assembly lines and quality control—is the most critical factor for cost reduction.

Anderson identifies three niche markets for advanced nuclear: military/defense applications, remote locations currently served by diesel generators (mining, Arctic communities), and data centers for AI. She argues data centers represent the most significant opportunity for scaling and profitability, as hyperscalers provide the financial certainty and order books necessary for project financing.

Regarding supply chain challenges, Anderson discusses bottlenecks in uranium conversion (with capacity concentrated in Russia and only one U.S. facility, which is aging) and enrichment technologies. She compares emerging enrichment methods—laser enrichment via companies like General Atomics and GLE, and alternative approaches like Hexium's lithium metal process—and notes that laser technologies show promise for greater efficiency and isotope selectivity.

On the turbine and power conversion side, Anderson highlights supercritical CO2 turbines as a transformative technology that can achieve 50% thermal efficiency (versus 30% for traditional steam turbines), reduce equipment size for mass manufacturing, and be deployed quickly alongside small reactors. She also discusses solid-state transformers and power management devices as critical for interconnecting distributed nuclear and renewable generation to data centers.

Anderson addresses why fusion warrants investment despite fission being more mature. She argues that fusion power plants could be operational by the mid-2030s—roughly the same timeline as advanced fission reactors—and emphasizes technological breakthroughs that have transformed the fusion landscape: high-temperature superconducting magnets have dramatically reduced reactor size from stadium-sized to house-sized, laser costs have plummeted due to advances in laser technology, and computational simulation now enables design iteration in hours rather than years. She contends fusion offers advantages including elimination of uranium mining/enrichment/storage costs, hydrogen fuel availability in seawater, and comparable power density to fission without uranium supply chain complexity.

Anderson defends the tritium fuel cost argument by explaining that modern fusion plant designs close the tritium fuel cycle through blanket technology using lithium, meaning the power plant produces its own tritium, requiring only deuterium input from seawater. She identifies investment opportunities in both integrated fusion power plant companies (Commonwealth Fusion Systems, TAE Technologies) and enabling technology providers (magnets, lasers, materials science companies).

Beyond nuclear, Anderson discusses other energy-critical technologies: silicon carbide semiconductors enabling smaller, more efficient power electronics and thermal tolerance in extreme environments; rare earth element refining and aluminum processing; supercritical CO2 bottoming cycles that extract additional efficiency from existing infrastructure; data center grid interconnection technologies and virtual power plants; and enhanced geothermal drilling technologies by companies like Quaise that aim to access heat sources closer to load centers.

On data center power requirements, Anderson explains that NVIDIA's roadmap toward 800-volt distribution means data centers must handle unprecedented power density—40 MW facilities the size of six Sam's Clubs, with individual equipment cabinets drawing megawatts. This creates demand for sophisticated power management and grid interaction technologies.

Regarding robotics, Anderson's perspective (as a non-expert) is that industrial robotics for dangerous, remote, or toxic environments will see more near-term deployment than humanoid home robots, citing regulatory and safety concerns in the U.S. She mentions companies like PICA (agricultural drones) and Fort Robotics (human-robot collaborative workspaces).

Anderson concludes by describing Timescale Ventures, her early-stage deep tech fund focusing on energy, industrial robotics, logistics, mobility, manufacturing, and compute. She attributes the fund's timing to a convergence of mature talent stacks (engineers from SpaceX, Tesla, Rivian), downstream capital availability, and dramatically improved hardware development tools (simulation, prototyping, off-the-shelf robotics components). She emphasizes that speed-to-market is essential for financial and societal impact.
