Homerun: Uniquely Positioned to Prevent Future Iberian Blackouts
The recent unprecedented power outage across Spain, Portugal, and parts of France on April 28, 2025, has highlighted critical vulnerabilities in Europe’s energy infrastructure. As shareholders of Homerun Resources Inc., you should know that our company is exceptionally well-positioned to address these challenges with our innovative energy storage solutions currently under development and deployment.
The Iberian Peninsula Blackout: A Wake-up Call for Energy Security
The massive blackout that struck the Iberian Peninsula was one of Europe’s most substantial power failures in recent history. It affected tens of millions of people when approximately 15 gigawatts of power-equivalent to 60% of Spain’s national demand-was lost in just five seconds. The outage lasted over ten hours in some locations, grounding flights, halting train operations, interfering with mobile networks, and causing widespread disruption to critical infrastructure.
While investigations into the exact cause continue, what’s clear is that grid stability and resilience have become more crucial than ever. Spain’s Prime Minister Pedro Sánchez has emphasized the need to investigate and implement measures to prevent future occurrences. This is precisely where Homerun Resources’ technologies can make a significant difference.
Our Thermal Energy Storage Solution: A Path to Grid Resilience
Homerun Resources is developing a groundbreaking thermal energy storage system in collaboration with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). This system represents a timely and potent solution to the exact challenges exposed by the recent blackout.
How Our Thermal Energy Storage Addresses Grid Vulnerability
Our thermal energy storage technology offers several advantages that directly address the vulnerabilities exposed during the Iberian blackout:
Long-Duration Storage Capacity: Unlike conventional batteries, our thermal energy storage system can store energy for multiple days, providing extended backup power during emergencies. This would have been invaluable during the recent 10+ hour blackout in Spain and Portugal.
Grid Load Balancing: Our system decouples electricity generation from consumption by storing energy when production is high (such as during peak solar or wind generation) and releasing it when needed. This capability is vital for managing the rapid fluctuations that reportedly contributed to the Iberian outage.
Cost-Effectiveness and Longevity: Our thermal energy storage solution has lower capital and operating costs compared to conventional battery energy storage systems and can last up to 30 years, significantly reducing replacement expenses.
Scalability Without Geographic Constraints: Unlike pumped hydro storage (which currently provides 95% of global energy storage), our technology can be deployed virtually anywhere, from onsite megawatt-hour storage to utility-scale gigawatt-hour long-duration storage.
Our Unique Silica-Based Approach
What sets Homerun apart is our innovative use of high-purity silica sand in thermal energy storage:
– Our CRADA (Cooperative Research and Development Agreement) with NREL has confirmed the surprisingly high purity of our silica sand, making it exceptionally suitable for thermal energy storage applications.
– The system is already prepared for commercial pilot installation.
– Our thermal storage technology can enhance energy security and resilience by providing low-cost, long-duration capabilities specifically designed to overcome blackouts and extreme weather events that can cripple local electric grids.
Complementary Battery Energy Storage Through SeisSolar Acquisition
Complementing our thermal storage innovation, our recent strategic acquisition initiatives position us to offer comprehensive battery energy storage solutions:
– Our binding agreement to acquire a 60% stake in SeisSolar Fotovoltaica (with rights to acquire the remaining 40%) gives us access to an established European leader in B2B alternative energy solutions.
– SeisSolar brings over 2,800 active customers across Southern Europe and North Africa-including the regions most affected by the recent blackout-and has generated over EUR70 million in cumulative revenues from 2022-2024. We anticipate the evident need for energy storage solutions to improve growth across SeisSolar’s unique product shelf.
– We will integrate AI Energy Management and Control System Solutions into this extensive network, enabling more intelligent and responsive energy management during grid instability events.

Why This Matters for Grid Stability
Battery energy storage systems provide crucial rapid-response capabilities that can help stabilize grids during sudden fluctuations:
– Grid-scale batteries offer extremely fast response times, even faster than thermal power plants, allowing them to quickly address real-time grid needs during emergencies.
– These systems can provide essential grid services through various software and hardware features specifically designed to maintain grid reliability.
– Real-world examples already demonstrate how battery storage economics can outperform traditional gas-fired power plants in supporting grid reliability.
A Complete Solution for the Energy Transition
The combination of our long-duration thermal energy storage and battery energy storage systems creates a comprehensive approach to grid resilience:
Immediate Response: Our battery systems can respond within milliseconds to sudden fluctuations like those that triggered the Iberian blackout.
Extended Backup: Our thermal storage provides the long-duration backup needed during prolonged outages.
Regional Expertise: Through SeisSolar, we have established relationships and operations in the exact regions affected by the recent blackout.
Renewable Integration: Both technologies excel at managing the intermittency challenges associated with increasing renewable energy penetration.
We Are Positioned to Lead in the Post-Blackout Energy Landscape
The April 2025 Iberian blackout has created heightened awareness among governments, utilities, and consumers about the critical importance of energy storage and grid resilience. As European authorities investigate the causes and seek solutions to prevent future occurrences, Homerun stands ready with market-ready technologies that directly address these concerns.
Our thermal energy storage system developed with NREL and our strategically planned acquisition of SeisSolar give us a unique position at the intersection of long-duration storage and rapid-response battery systems-precisely the combination needed to prevent catastrophic grid failures like the one experienced across Spain and Portugal.
As shareholders, you can be confident that Homerun is not just participating in the energy transition but is strategically positioned to provide essential solutions to one of its most pressing challenges: maintaining grid stability and resilience in an increasingly complex energy landscape.
