AI Is Breaking the Grid. A Flywheel Could Fix It.

Episode Summary

Executive Summary: The episode centers on Nate Walkashoff’s journey from EMT and medical-device inventor to CEO of Taurus, a flywheel-based energy storage company. The conversation explains how Taurus uses long-duration flywheels plus batteries and software to solve grid congestion, fast-frequency response, and emerging AI/load-growth challenges, while also highlighting utility partnerships, manufacturing constraints, and workforce development as core to scaling the technology.

Main Topics: Nate Walkashoff’s origin story (Priority: 5/5): Nate describes inventing patient-transport equipment as an EMT, building a company from scratch, and later translating that entrepreneurial mindset into energy storage. How Taurus flywheel storage works (Priority: 5/5): The discussion explains Taurus’s magnetically levitated, vacuum-based flywheel system, its role in long-duration storage, and why it reduces battery cycling and extends asset life. Utility partnership and market fit (Priority: 5/5): The hosts and Nate discuss how Rocky Mountain Power and Pacific Corp helped shape the product around real grid needs like fast-frequency response, sub-transmission support, and congestion relief. AI/data centers and load growth (Priority: 4/5): The episode connects rapid load growth from GPUs and data centers to the need for flexible grid assets that can shape demand at the edge and free up constrained capacity. Manufacturing scale and interconnection barriers (Priority: 4/5): Nate explains that Taurus’s own factory faced major delays and limited power availability, showing how grid queues and site power constraints hinder advanced manufacturing. Workforce development and community college partnership (Priority: 4/5): Taurus’s training pipeline with Salt Lake Community College is presented as a model for advancing workers from basic assembly roles into high-skill manufacturing jobs. Communications, leadership, and narrative discipline (Priority: 3/5): The hosts reflect on the importance of repeating a clear message, controlling the narrative, and building trust with utilities, policymakers, and the public.

Key Arguments: Grid problems are often short-duration and localized, so flywheels can be better suited than purely chemical batteries for many distribution/sub-transmission use cases. Taurus’s combination of flywheels, batteries, firmware, and software can provide both fast dispatch and firming services while reducing battery wear. Utilities helped reveal the real use case: inertial-based storage can function as a transmission/distribution asset near load, not just as behind-the-meter backup. AI-driven load growth and electrification are creating new load shapes that require edge intelligence and flexible assets. Scaling clean-energy manufacturing depends not just on capital, but on power availability, interconnection speed, and workforce pipelines. Partnership with utilities is more effective than competing against them; Taurus is designed to integrate with utility operations and controls. Training people from entry-level/manual work into advanced manufacturing roles is both socially valuable and strategically necessary for U.S. industrial growth.

Data Points: Initial pay at EMT role: $7.14/hour - Nate describes starting out as an EMT basic before inventing his first company. Personal savings used for prototype: $200 per paycheck every two weeks - He saved this amount to build his first ambulance-related prototype. Ambulance cot market share: 70% of U.S. hospitals - The Parislide hospital evacuation lift reached broad adoption after acquisition. Age at acquisition: 29 years old - Nate says he was the youngest medical device CEO acquired by a Fortune 100 company. Tree farm size: 9,000 conifers - The family tree farm in Sandy, Utah was the setting for the Taurus invention story. Family farm energy offset: 85% - Solar, hydro, and flywheel systems offset most of the tree farm’s energy costs. Flywheel recyclability: 95% recyclable - Nate describes Taurus’s early flywheel architecture. Battery architecture: 48-volt - The first Taurus flywheel architecture used a 48-volt system. Commercial dispatches in year 1: 33 - Early utility integration with Rocky Mountain Power. Commercial dispatches in year 2: 66 - Dispatch frequency doubled as the program proved itself. Commercial dispatches in year 3: 127 - Dispatch count continued to rise with growing load needs. Commercial dispatches in following year: 359 - Program utilization accelerated sharply. Projected dispatches this year: 500+ - Nate expects the program to exceed 500 dispatches. January 2025 partnership size: 70 MW - Rocky Mountain Power demand-response partnership announced. Expanded Pacific Corp program: Up to 500 MW - Expansion across six states by September. Project size unit: 1 MW chunks - Taurus systems can be scaled in Lego-brick style modules. Typical deployment size: 20 MW and below - Taurus’s sweet spot is sub-transmission/distribution projects. Installation time: 3.5 months - Time from location to installed project. Grid capacity unlocked: 33 GW - Nate says broad deployment could free congested capacity across the system. Factory service at old site: 4,000 amps - The earlier facility had insufficient electrical service for manufacturing. New factory power: 8 MW - Even the larger Salt Lake City facility initially had limited power. Factory size: 540,000 square feet - Taurus moved into a much larger facility called Giga One. Factory workforce: 300 people - Jamie references the company’s growing workforce. Production growth: 76% - Jamie notes increased production at the factory. Intern cohort size: 80-90 interns - Taurus’s community college/university pipeline supported a large internship cohort. Entry-level wage: $22-$28/hour - Starting pay in Taurus’s workforce development ladder. Advanced wage range: $110,000-$170,000 - Potential wage progression for workers who move up through training. Vehicle/hybrid route threshold: Less than 350 miles - Jigger’s answer on electric aviation viability. Technology readiness level: TRL 8 - Jigger estimates small electric/hybrid aviation technologies are near commercialization.

Pivotal Quotes: "You have an inertial-based energy storage device." — Gary Hogebeen (quoted by Nate): The utility CEO reframes Taurus’s technology as grid-relevant inertia rather than just storage. "We're the pseudo-fed of the grid." — Nate Walkashoff: He describes Taurus as relieving congestion and moving clean power to load more efficiently. "Building products is candidly easy, while building people and teams is the hardest thing to do." — Nate Walkashoff: Nate reflects on leadership and organizational culture.

Implications: The episode frames flywheel storage, utility partnership, and workforce development as practical tools for unlocking grid capacity, supporting AI-era load growth, and strengthening U.S. manufacturing. It suggests the biggest bottlenecks are now interconnection, power access, and execution, not just technology.
