Access to clean, portable, reliable power is a life saving and world changing solution. We urgently need to make power simpler and cleaner.

Why Joule Case?

***Notice: We've been made aware that there have been a few issues keeping investors updated through the Wefunder platform. While the internal development team is working on a resolution, we've chosen to push our closing date back seven days. The show goes on until February 7th!

Just one week before our Community Round closes, we have officially announced the Olympus Power Platform—a BOLD next step towards more sustainable portable power.

This product package provides a scalable, high-performance system that addresses some of our biggest challenges including EV Charging, Event/Festival Power, Grid-Scale Backup, Emergency Response/Resiliency, and much more.

The electricity our world depends upon is no longer reliable.

Our lives rely on power—yet our current utilities have shown time and time again that businesses and people cannot depend on them.

The United States electrical grid is the most complex system ever designed yet it is outdated and failing.

  • There were 10X as many significant power outages in 2020 as there were in 2000.
  • 70% of all electrical transmission lines are past their 50-year expected life.
  • Now electrical utilities are being disrupted with decentralized renewable solar panel generation and the high demand EV fast charging that they do not have the capacity for.

Electrical utilities are spending massive amounts of capital trying to solve this problem..

They spent an estimated $140 billion on infrastructure and clean energy upgrades in 2022 and plan to spend another $140 billion in 2023. Even with this massive capital influx, the US will still face a $200 billion funding gap for what is needed to maintain the grid and meet renewable targets for 2029.

Joule Case provides innovation in a largely stagnant battery market by replacing noxious generators and miles of expensive and cumbersome electrical transmission lines with clean, safe, cost-efficient renewable power. The company’s long-term vision is to create a truly decentralized electrical grid that can withstand challenging conditions without causing widespread outages.

Joule Case’s patented battery system can use any type of battery chemistry and generate serious amounts of power—enough to match the grid. This single, easy-to-use system can be built into custom bundles to suit anyone’s needs—even high voltages and multiphase power systems needed for large applications.

Joule Case is a perfect solution for most power needs regardless of the business or market. Our current customers include wineries, aquariums, festivals, events, large video display manufacturers, home builders, EV charging companies, food trucks, and even utilities themselves. No matter the size or scale of the application, Joule Case’s system has proven to be a better option than generators or the electrical grid.

Mobile businesses include mobile car detailers, groomers, deep cleaners, disaster recovery, electricians, plumbers, landscaping trucks, and more. These entrepreneurs are always in their vehicles driving to the next customer and need clean, reliable power that’s ready to go when they get there. Many currently use generators that are ripe for replacement. A reliable, convenient power source is absolutely critical to keep these businesses operating.

    There are 35,000 food trucks in the United States alone. Each one has food being prepped with the smell, pollution, and noise of a generator contaminating the experience for both employees and customers. Generators are the biggest frustration point frequently expressed by food truck owners. Not only are they noisy and noxious, but they also fail frequently and require regular maintenance (not to mention rising fuel costs). Now, there are dozens of food trucks that have replaced their generators with a quiet and clean Joule Case system.

      Tiny homes are built for light infrastructure and minimal environmental impact. Connecting these homes to the main power grid can be incredibly expensive, not to mention an eyesore. Considering their low power requirements and low capital costs, these homes are ideal candidates for a Joule Case system, which can function as the microgrid solution for any type of tiny home.

      • Traditional electrical grid is unavailable and expensive to access
      • Alternative gas generators are loud and maintenance intense
      • Tiny home owners want clean energy

      Brands such as Dyson, Red Bull, LifeWater, T-Mobile, and GM have dozens of teams of brand activators ready to attend the next state fair, NASCAR race, or music festival, or to set up shop downtown in a major city. Modern pop-ups require power—and just like with food trucks, the smell, noise, and maintenance requirements of a traditional gas generator detracts from the experience for everyone involved. Joule Case solves all these pain points, while also being a greener choice brands are proud to make.

        The EV industry currently faces a significant bottleneck: there simply aren’t enough charging locations. The logistics and capital required to replace gas pumps with EV charging stations is massive;. no utility is prepared for the electrical capacity it necessitates. Joule Case’s energy storage systems have the adaptability to be charged by solar panels and other renewable sources or through regular power outlets, and use their patented modular design and swappable units to help in any situation – big or small.

        Every business and utility is looking for ways to ensure they have reliable power for their critical systems, especially in the event that the grid fails. There were 10X more electrical outages in 2020 than there were in 2000; some recent outages, like the 2021 Texas power crisis, have been so severe that they caused hundreds of billions of dollars in property damage and resulted in hundreds of deaths. There is no justification for such a tragic catastrophe happening in the 21st century. By offering truly decentralized, flexible energy storage, Joule Case is flipping the script and providing an innovative way to ensure that reliable backup power is always available, no matter the conditions.

        Most portable and backup power is noisy, toxic, and expensive—and poses a serious public health safety issue. But even as we transition toward a greener grid, we still haven't unlocked the potential of renewable energy generation. This is where Joule Case’s energy storage system really leads the way.

        Finally—a major shift in the battery scene. Prices have dropped 87% in a decade, and big initiatives plus an influx of capital is pushing the sector forward—fast. Joule Case uses the best battery tech on the market, combined with an ingenious way to make them play nicely together in a stackable, swappable, customizable format.

        Their first mission? Making music festivals greener.

        Power is one of the largest production costs for a music festival, and it can account for over 70% of its core carbon footprint. Recent lawsuits against Coachella and other concerts have revealed dangerously high levels of toxins in the air—from diesel generators—at these events. And with fuel costs rapidly rising and the energy market forecast as increasingly volatile, something’s gotta give.

        The music festival sector has a unique opportunity to contribute to CO2 reduction, showcase new innovation, and engage audiences. Joule Case is partnering up with LIVE Nation, Insomniac Events, and festivals like EDC and Burning Man to transition from loud, harmful generators to renewable, stackable energy.

        "The potential for Joule Case in music festivals is massive."

        - Rutger Jansen, Senior VP Production and Operations @ Insomniac

        With events coming back bigger than ever, we believe Joule Case is poised for incredible growth. Starting with Insomniac Events, organizer of Electric Daisy Carnival, Joule Case is on a mission to replace all the dirty diesel generators at concerts and outdoor events with clean, safe, renewable power.

        The $30B lithium-ion battery market is predicted to spike four-fold over the coming decade. Event power itself is a fast-growing market at 25% CAGR that sits directly in sight for Joule Case technology.

        Toxins from diesel generators are known to contribute to cancer and premature death, and combined with other compounds in sunlight they form ozone, a potent trigger for asthma attacks and other health issues. What started as a purely environmental issue has quickly escalated into a public health and safety issue, and the verdict is in: generators need to go.

        As NPR outlines in this article, the rising occurrence of natural disasters is often followed by a spike in deaths from carbon monoxide poisoning. After the legendary cold snap brought the State of Texas and it’s power grid to its knees in February 2021, at least 11 deaths were confirmed and more than 1,400 people sought care at emergency rooms and urgent care clinics for carbon monoxide poisoning during the weeklong outage.

        Additionally, with California signing into law Assembly Bill 1346, which will effectively ban small gas-powered generators, the widespread transition to clean battery alternatives has begun.
