Why the 2019 Conference Still Matters Today

While energy storage conferences happen annually, the 2019 edition in San Diego became a turning point for industry professionals. solar executives nibbling avocado toast while debating lithium-ion vs. flow batteries, all against California's sunny backdrop. Little did they know, these discussions would become crucial armor against today's policy challenges.

Key Themes That Predicted Current Trends

• Grid-scale storage integration challenges
• Residential solar-storage hybrid systems
• Emerging battery chemistries beyond lithium
• Utility rate structure impacts on ROI

Tom Starrs, VP at EDP Renewables, famously quipped during a panel: "We're not just storing electrons – we're storing economic resilience." This foreshadowed today's market turbulence where energy storage systems buffer against policy shifts.

Policy Crossroads: Then vs. Now

The 2019 conference occurred during relative policy stability, unlike today's climate. Recent developments show:

Case Study: From Theory to Turbulence

Sunrun's 2019 presentation on virtual power plants now reads like tragic irony. Their projected 300% growth collided with 2025's installation stagnation – proof that even the best energy storage solutions need favorable regulatory winds.

Technological Seeds Planted in 2019

Several 2019 exhibitors showcased prototypes now dominating markets:

• Second-life EV battery systems
• AI-driven storage optimization software
• Non-lithium alternatives for long-duration storage

One startup's graffiti-style booth slogan – "Your electrons deserve better retirement plans" – became an industry meme, symbolizing creative approaches to energy storage challenges.

Networking Ripples Through Time

The conference's matchmaking app data reveals:

• 47% of 2019 connections led to 2020-2024 collaborations
• 12% of seed-stage presenters became 2025 market leaders
• 8 policy frameworks drafted in conference workshops became state legislation

As solar stocks fluctuate wildly in 2025, veterans recall 2019's hallway conversations about "political risk hedging" – advice that's now worth its weight in battery-grade lithium.

The Hydrogen Wild Card

While most 2019 discussions focused on electrochemical storage, a lone hydrogen storage presentation drew skeptical crowds. Fast forward to 2025: that presenter's company now leads three DOE-funded green hydrogen initiatives.

Architecture Meets Energy Innovation

San Diego's venue choice proved prophetic. The convention center's own 2MWh storage system, showcased in 2019, became:

• A resilience model during 2023 grid emergencies
• A testbed for frequency regulation algorithms
• Proof point for municipal storage mandates

Conference organizers didn't just talk about energy storage technology – they literally powered their event with it. The 14% cost savings became a standard conference ROI metric.
