🪨 What product is the cornerstone of the US economy, enabling workers to commute every single day? What is the real trick to a truly circular economy? And how is this all tied to the end of World War I? For answers, we turn to Roger Miksad, president and Executive Director of Battery Council International, in discussion with Nate Kirchhofer, CEO of BioZen Batteries.

The rise of the electric starter and returning WWI service members-turned-mechanics helped launch a century-long battery industry that still powers modern life. Roger shares how BCI, founded in 1924, grew from a handful of “garage-scale” manufacturers into the longest-running trade association for the North American battery industry, now steering its second century at the heart of the energy transition.

Learn about Roger’s path: a lawyer who engaged with batteries by way of environmental compliance, worker safety, and end-of-life rules for an intensely regulated industry. Nate and Roger unpack how BCI’s members voluntarily operate with worker-exposure standards far tighter than federal requirements, and how standardization—right down to knowing which battery fits every mass-market vehicle on the road—became a hidden superpower for innovation rather than a constraint. Along the way, they highlight “low-voltage” batteries: starter and 12-volt systems underpin everything from conventional cars and EVs to forklifts, mining equipment, telecom, and backup power, even as new chemistries and applications emerge.

The episode then steps into energy storage for AI-era data centers and critical infrastructure. Nate brings in a real-world conversation about insurability as a gating feature for battery adoption, while Roger explains why fire codes, safety engineering, and early engagement with fire marshals can make or break a project long before a single cell is installed. Together they explore how flow batteries and other aqueous systems are entering the conversation, why BCI chose to support the flow battery community through events like Flow Batteries North America, and how pre-competitive collaboration can give customers confidence without dulling competition. It’s a nuanced look at how technology choice, risk, and regulation all collide.

Finally, Nate and Roger connect policy and circularity, from BCI’s 1980s model recycling law that helped create a profitable closed loop for lead batteries—no subsidies required—to the chemistry-agnostic 45X Advanced Manufacturing Production Credit that’s now similarly reshaping where and how batteries are made in the US.

Roger makes the case that batteries are politically “purple” rather than a niche green add-on, and shares candid advice for anyone who wants to work in energy storage: show up, meet people, and bring your best ideas to an industry that actively welcomes new blood. If you’ve ever wondered how standards, safety, recycling, and smart incentives quietly determine which chemistries win—and how you can be part of that story—this conversation is your invitation.

📈 Are Flow Batteries poised to break out in North America? How do AI and data centers compare to electric utilities in their priorities? What is FBNA and how can I attend? Kicking off Season 2 of Beyond Lithium, returning guest Russ Weed (President, CleanTech Strategies) sits down with Nate Kirchhofer (CEO, BioZen Batteries) to unpack how the policy winds have shifted, why private demand from data & AI centers is reshaping storage, and what that means for commercialization. They spotlight the inaugural Flow Batteries North America (FBNA) conference 27-29 October in Chicago: what it is, who it’s for, and why it’s arriving at exactly the right moment.

Russ previews the FBNA program: keynote from the Illinois Commerce Commission chair, three real-world case studies, sessions on use cases, controls/software, bankability, supply chain, an address from Flow Batteries Europe, and a finale on data/AI center applications. Expect a practical, commercialization-first vibe—not just lab talk—including a special video from Dr. Maria Skyllas-Kazacos on the history of the vanadium flow battery, plus an in-person tour of a nearby flow battery facility.

The conversation zooms out to the macro picture: the 45X production tax credit and the IRA’s treatment of energy storage (including standalone eligibility) have kept momentum intact—even as solar/wind face new cliffs—paving the way for a North American supply chain for Flow Batteries. Russ makes the case for proven tolling agreements and revisits the classic cost-schedule-performance triangle: utilities tend to optimize for cost + performance, while data/AI centers prioritize schedule + performance—an opening for flow batteries to scale and drive costs down. If you’re building, buying, or financing long-duration storage, this episode is your roadmap. And Chicago is your next stop.

🚒🧯 What’s the best strategy to prevent future battery fires? What type of energy storage system (ESS) does the fire department think is best? How do we build safe energy storage systems? For answers, we turn to Doug Wilson—Senior Fire Plans Examiner for Scottsdale, AZ Fire Department—in conversation with BioZen Batteries’ CEO Nate Kirchhofer.

You’ll hear about Doug’s 30+ year background in both public and private Fire Protection as a registered Fire Protection Engineer, and some insights about the unique career path that that role entails, as well as some of the handful of universities that offer 4-year and/or Masters degrees in Fire Protection Engineering.

The conversation dives into the challenge of proactively staying ahead of new ESS technologies while working from a retrospectively-published 3-year code cycle for the International Fire Code (IFC) from the International Code Council (ICC). Doug comments that, “the Fire Code is published every three years. … The previous one was 2021 and the next edition will be the 2024 Code. When the 2021 code first started being written, it was in 2018, using 2018 technology. It wasn't adopted until 2022. So, in 2024, we were working with the best technology we had in 2018. We're six years behind right now.”

The episode moves to a conversation about the 2.16 MWh Li-ion battery ESS fire and deflagration event that occurred in Surprise, AZ in 2019, and some thoughts about the best practices to avoid similar in the future. (Spoiler: get the Fire Protection Engineers involved early!) It’s hard to know what you don’t know about the safety of a new technology, and the tension between the urgency of deployment and maintaining rigorous safety and testing makes it challenging.

Below are some links for the “what's required” (ICC), “how to do it” (NFPA), and “testing it” (UL) resources for ESS discussed in the episode:

The International Code Council (ICC), including International Fire Code (IFC):

• ICC IFC Section 1206: Stationary Fuel Cell Power Systems
• ICC IFC Section 1207: Electrical Energy Storage Systems

The National Fire Protection Association (NFPA) Standards:

• NFPA 13: Standard for the Installation of Sprinkler Systems
• NFPA 855: Standard for the Installation of Stationary Energy Storage Systems

The Underwriters Laboratories (UL) Standards

• UL 9540: Energy Storage Systems and Equipment
• UL 9540A: Test Method for Battery Energy Storage Systems (BESS)—the only consensus standard explicitly cited in NFPA 855
