The rapid evolution of launch technology is transforming what is considered possible in space. According to Erika Guerrero, founder and CEO of Electric Goddess, this change is not only expanding access, but is also redefining how batteries should perform in one of the most challenging environments that exists.
Guerrero explains that when rockets can carry more hardware into space in a single launch, companies begin to imagine projects that were previously unrealistic. This includes initial concepts for resupply stations, larger communication platforms, manufacturing units or even future structures linked to space tourism. Despite their differences, he notes that they all depend on one essential element: a power system designed and validated to operate safely in space.
From Guerrero’s perspective, this transition occurs at the same time as battery innovation accelerates on Earth. It highlights that new chemistries, formats and test methods are constantly emerging, prompting companies to seek greater technical clarity. “It is often underestimated how complex batteries really are,” he says. “But the best battery, whether in space or here on Earth, is the one you never have to think about.”
Any project that operates beyond Earth, Guerrero explains, depends on energy systems subjected to extreme conditions: exposure to radiation, thermal cycles, vacuum environments and the complexity of in-orbit repairs. “Companies must evaluate how long a battery needs to last in space for mission value, what chemistries are suitable for specific uses, and what integration steps help avoid premature failure,” he says. “The margin of error that can be tolerated in consumer devices does not exist in a space program.”
Growing interest in space data centers, satellite constellations, and early human habitat concepts reinforces this need. Recent research illustrates the magnitude of this momentum: the global space economy has surpassed $546 billion, and is expected to continue expanding as new launch vehicles come into operation. Guerrero emphasizes that each of these applications requires a battery system capable of withstanding long-duration missions.
Guerrero emphasizes that his team’s role is not to manufacture batteries, but to guide companies through the scientific and engineering steps necessary to design and validate specialized systems. “Our work focuses on helping teams understand what they need, how to build it, and how to demonstrate that it will survive the mission. In space, second chances are extremely costly,” he explains.
Improvements in access to space directly influence this challenge, he adds. “Larger, reusable rockets significantly increase the volume of hardware that can be sent to orbit in a single launch, which in turn expands the types of missions that companies dare to pursue,” says Guerrero. “This creates a change of scale in the industry, one that makes battery expertise not only relevant, but fundamental.” He notes that reducing launch costs opens the door to more ambitious systems: larger telescopes, larger platforms, modular habitats and new types of commercial operations.
“This expansion requires more solid technical planning, because greater volume and mass usually translate into more complex energy demands,” explains Guerrero. “Even the choice of cell format requires careful analysis, especially as the industry transitions to larger designs. Testing methodologies must also consider manned and unmanned applications, safety aspects, thermal extremes, cell sealing and associated electrolyte loss rates, as well as longevity factors that have a much greater impact off Earth than on it.”
The need for rigorous validation also extends to security. Thermal runaway events remain one of the risks in lithium-based batteries, reinforcing the importance of precision in design and testing in high-risk environments. Guerrero explains that when a battery will be used in an environment close to humans, whether in a future habitat or in a scientific module, the standard is not simply reliability, but almost zero tolerance for failure.
He notes that this philosophy guides Electric Goddess’ consulting approach. “We designed and validated with the mindset that someone we love could be right next to that battery,” he says. “That level of care is non-negotiable.”
As new space applications accelerate, Guerrero believes companies will increasingly look to specialized advisors to help bridge the gap between theoretical performance and actual mission readiness. He explains that battery development is not limited to choosing a promising chemistry, but involves understanding constraints, timelines, integration sequences, and system-level implications.
Their vision is that the future of space will be defined by organizations capable of combining bold ideas with proven design. “Energy storage is a critical element for the success of any space program,” he says. “When the risk level is this high, a validated battery is not optional.”
