Why Long-Duration Energy Storage Breaks Batteries – and How Hydrogen Fixes It with Mia Rath

Hardware to Save a Planet · 22 Jan 2026 · 52m · Episode 94

What this episode covers

Mia Rath, co-founder and CTO of Lument, explains how her company uses solid-state metal hydride storage to solve the decoupling of power and energy capacity in long-duration energy storage. She details the material science behind their high-entropy alloys, the process of manufacturing the hydride powder in-house from domestic ore, and the engineering challenges of scaling reactor throughput. Rath discusses Lument's transition from a garage prototype to installing a 220 kWh system in a San Francisco warehouse, highlighting the permitting advantages and cost benefits for commercial customers and data centers.

    Unlocking the renewable energy revolution with Ramya Swaminathan of Malta Inc.

    Ramya Swaminathan, CEO of Malta Inc., explains how her company uses molten salt to provide low-cost, long-duration energy storage for the grid, spinning out of Google X in 2018. She details the technical advantages of thermal storage over lithium-ion batteries, specifically regarding scalability and supply chain security, and discusses the company's transition from pilot validation to commercial deployment. Swaminathan also reflects on her previous ventures in hydrokinetic power and the challenges of integrating renewable energy into the existing US grid infrastructure.

    How to Save a Planet: Spark Tank! How Do We Solve the Energy Storage Problem?

    Hosted by Alex Bloomberg, this crossover episode of 'How to Save a Planet' features Shayle Kann of Energy Impact Partners and Dr. Leah Stokes of UC Santa Barbara evaluating three long-duration energy storage technologies in a 'Spark Tank' format. The judges assess pumped hydro storage at Northfield Mountain, compressed air energy storage from Hydrostor, and thermal storage using molten salts developed by Dr. Cristina Prieto. They debate the scalability, efficiency, and industrial applications of each, ultimately favoring compressed air and thermal solutions over pumped hydro due to site limitations.

    Four ways to store sunlight

    Andy Lubershane, partner and head of research at Energy Impact Partners, joins Shayle Kann to discuss four primary methods for storing solar energy: lithium-ion batteries, heat storage, iron-air batteries, and hydrogen. Lubershane argues that while lithium-ion dominates short-duration grid balancing, its cost floor limits its viability for long-duration needs, creating opportunities for cheaper alternatives like thermal storage and Form Energy’s iron-air batteries. He also explains how hydrogen can serve as ultra-long-duration storage, particularly through blending into existing gas turbine infrastructure, and notes that carbon capture and storage (CCS) remains a significant competitive alternative for maintaining fossil-fuel-based resilience.

    What do you do with a 100-hour battery?

    Mateo Jaramillo, CEO and co-founder of Form Energy, explains why 100-hour 'multi-day' iron-air batteries are necessary to displace mid-merit gas plants during prolonged weather events that lithium-ion cannot economically cover. He details Form's cost targets of $20/kW for these systems and their specific value propositions for utilities like Georgia Power and Xcel Energy in managing load growth, decarbonization, and transmission congestion. Jaramillo also discusses the competitive landscape, including hydrogen and carbon capture, and the operational reality of dispatching these assets for both capacity reliability and seasonal energy shifting.

    138. How Thermal Batteries Will Scale Sustainable Energy ☀️🔋

    Hosts Daniel and For Bode discuss Antora Energy, a startup founded by MIT alumni Kearns and Beerman, which uses thermal batteries to solve renewable energy intermittency. The technology stores excess solar and wind power as heat in carbon blocks and converts it back to electricity using thermal photovoltaics, offering a longer-lasting and more recyclable alternative to chemical batteries. The hosts highlight the company's recent Series A funding, new manufacturing plant, and upcoming industrial projects targeting the chemical and food sectors.
