SAILIS

SAILIS is a Nova Scotia based spinout from Solterra with 100% mineral interest in the Beckwith salt dome, initially focused on energy storage and utilizing brine recovery for battery supply along a primary structure of the natural hydrogen camp, directly in the middle of: QIMC; Kavenex Energy and Koloma, the heavily financed U.S. natural hydrogen explorer that has raised more than US$400 million from investors including Breakthrough Energy Ventures, Khosla Ventures, Mitsubishi Heavy Industries and United Airlines; and Primary Hydrogen. The concept now is to leverage potential hydrogen exploration to finance drilling and investigation of both economic salt and underground storage such as gravity related so that all options are de-risked to make some level of discovery. If it isn't flowing it needs to go somewhere, and that somewhere has a lot of back up opportunities as well... Solterra's other project Conduit Metals also hold the Westchester and Sugarloaf IOCG projects overlapping the main,.deep faulted corridor, with all the same geology. #criticalminerals #energystorage #batteries #salt #SIB #GESS #BESS #gravity #thermal #CAES #naturalhydrogen #hydrogen #copper #cobalt #rareearth

🔋 Sodium-Ion vs. Lithium-Ion: The Next Frontier in Energy Storage & Safety as a waste from natural underground batteries with SAILIS As energy storage demands accelerate across grid infrastructure and fleet operations, the conversation around battery chemistry is shifting beyond raw energy density toward thermal stability, supply chain resilience, and logistics safety. While Lithium-ion (LIB) chemistries remain the gold standard for volumetric energy density in long-range EVs, Sodium-ion batteries (SIBs) are emerging as a compelling alternative for stationary energy storage (BESS) and commercial applications. Here are four key operational and safety distinctions: 1️⃣ Enhanced Thermal Stability & Safety Margins. Accelerating Rate Calorimetry (ARC) and abuse testing demonstrate that SIBs exhibit higher thermal runaway onset temperatures (290^\circ\text{C} - 310^\circ\text{C}) and lower peak heat release rates compared to high-nickel LIBs. Additionally, sodium’s intercalation dynamics in hard carbon lower the risk of dendrite-induced internal short circuits during fast charging. 2️⃣ Zero-Volt (0\text{ V}) Transport & Logistics. Unlike lithium, sodium does not alloy with aluminum at low potentials. This allows SIBs to use lightweight aluminum foil for both cathode and anode current collectors, enabling full discharge to 0\text{ V} (0\%\text{ SOC}) for freight shipping. Transporting cells at zero state-of-charge eliminates stored electrochemical energy and significantly lowers freight risk. 3️⃣ Cold-Weather Operational Retention Due to lower ionic desolvation energy barriers, SIBs maintain strong performance in sub-zero environments, retaining >70 to 80% capacity at -40C, an area where conventional LFP systems encounter elevated internal resistance. 4️⃣ Supply Chain & Material Abundance By replacing cobalt, nickel, and copper with abundant sodium, iron, and aluminum, SIBs reduce exposure to critical metal volatility while cutting baseline material costs for grid-scale deployment. The Takeaway: High-nickel lithium batteries will continue to dominate applications where weight and volume are premium constraints. However, for stationary storage, harsh-climate operations, and safety-critical installations, Sodium-ion represents a key step forward in sustainable energy infrastructure. Using a local source to refit lithium BESS to a safer SIB (while creating larger longer lasting energy storage) would be a good move, to prevent fires, build more durable industrial sized batteries to support wind energy and more. #EnergyStorage #CleanTech #BatteryTechnology #SodiumIon #SIB #RenewableEnergy #GridStorage #BESS #CAES #GESS #Salt #SafetyEngineering #Fires #Lithium

SAILIS is researching hybrid opportunities for inert underground energy storage to support grid demand and transition while using any wastes for even more energy solutions such as sodium ion batteries. Additionally, other possibilities include looking at improved ways to find closed loop systems for water recycling and advantages of geology for even data centers, lowering the risk to environment that also provide security of both data and energy in the event of various emergency situations. Deep Bedrock & Salt Cavern Excavations Physical & Electromagnetic Shielding: Housing infrastructure inside deep granite formations or solution-mined salt caverns (200–500 m depth) offers native protection against EMPs, severe weather, and physical threats while maintaining high thermal inertia. Enhanced Geothermal Systems (EGS): Pairing deep subsurface facilities with binary-cycle geothermal power systems allows high-density AI clusters to utilize earth-heat directly for baseline power, returning low-temperature fluid to cool the data halls. #data #datacenters #energystorage #batteries #SIB #salt 🔋 Energy Storage Technologies (Core & Emerging) #BESS #GESS #CAES #TES #RTES #EnergyStorage #LongDurationEnergyStorage #LDES #CompressedAirEnergyStorage #ThermalEnergyStorage #GeothermalEnergyStorage #BatteryStorage #HybridESS #CleanEnergyStorage 🌊 Subsea, Ocean & Geothermal Infrastructure #SubseaDataCenter #UnderwaterDataCenter #OceanTech #GeothermalEnergy #GeothermalTech #SubsurfaceEnergy #DeepWaterCooling #EGS #ProjectNatick #BlueEconomy #MarineEngineering #OffshoreTech 💻 Data Center & Tech Infrastructure #DataCenter #DataCenterDesign #GreenDataCenter #DataCenterCooling #ImmersionCooling #SustainableComputing #Hyperscale #Infrastructure #EdgeComputing #DigitalInfrastructure #AIDataCenter 🌿 Sustainability, Decarbonization & Grid Resilience #CleanTech #ClimateTech #Sustainability #Decarbonization #NetZero #ESG #GridResilience #GridInteractivity #PeakShaving #RenewableIntegration #EnergyTransition #BESS #CAES #GESS #EnergyStorage #SubseaDataCenter #GeothermalEnergy #GreenDataCenter #DataCenterCooling #CleanTech #ClimateTech #DigitalInfrastructure #EnergyTransition #NetZero #SustainableComputing

🚀 Unlocking the Subsurface: The Multi-Value Future of Energy Storage & Hydrogen Subsurface energy projects don't have to be single-purpose. Geological systems like Beckwith (and broader Windsor Group evaporite basins) offer a rare confluence where energy storage and resource exploration intersect. Rather than viewing underground formations strictly through a traditional lens, integrated energy platforms can simultaneously evaluate and stack multiple subsurface revenue streams: 💡 1. Subsurface & Mechanical Energy Storage (CAES + Gravity) * CAES (Compressed Air Energy Storage): Solution-mined salt caverns within bedded/diapiric evaporites provide high-capacity, long-duration energy storage (LDES) to buffer intermittent renewables and support grid stability. * Gravity Energy Storage (SGES): Heavy-mass solid or shaft-based gravity systems present an immediate, mechanical counterweight solution for rapid-response grid balancing without degradation or chemical waste. ⛏️ 2. Economic Salt & In-Situ Potential * Solution mining for CAES or underground hydrogen storage creates an immediate commercial pathway for high-purity economic salt production. * Coupled with in-situ thermal or chemical operations, these systems turn passive storage infrastructure into dynamic chemical and energy processing hubs. 🌱 3. Natural (White) Hydrogen & Helium Exploration * Major crustal fault zones and deep basement contacts juxtaposed against thick evaporite seals create ideal conditions for natural hydrogen generation, migration, and structural trapping. * Exploring for native H_2 alongside cavern development maximizes exploration ROI—targeting both naturally occurring green gas and artificial storage capacity in the same basin footprint. The Takeaway: The transition isn't just about replacing power sources; it’s about maximizing subsurface asset density. By stacking gravity storage, CAES, industrial salt recovery, and natural hydrogen exploration into a unified operational strategy, we transform regional geology into a multi-generational clean energy engine.

Power the world with #salt. Secure, safe & abundant.

Using waste salt for sodium ion batteries (SIBs), from the development of renewable sub-surface batteries such as CAES. Precursor Supply: The primary raw chemical precursors for cathodes are quickly developing Prussian Blue and iron salts, largely are inexpensive, non-toxic, and widely produced for dye and industrial applications already. With iron supply chains already established and growing battery metals projects (including partnering projects such as copper cobalt Conduit Metals, and LFP materials, iron and rare earths at Bathurst Rare Metals under the Solterra umbrella) in North America, establishing the greater supply of SIBs and to utilize spent lithium batteries for recycling into SIBs provides a more robust solution to energy security. SAILIS is introducing a secure earth battery while potentially supplying a need for more industrial sized batteries with a safer and sustainable solution and exploring the greater supply chain, partnerships and opportunities within this space. #salt #energy #CAES #SIB #battery #energy #energystorage #criticalminerals #metals #copper #cobalt #rareearths #phosphate #lithium #iron

Canada is increasing it's defense spending. The power grid is crucial not only to economy, building new assets, but to keep things moving in emergencies. Halifax, Nova Scotia is a central hub for naval defense. SAILIS is using the regional geology, the government's mandate for natural resource development, but proposing a safer, stable and sustainable solution that is locally sources. #salt It seems so common, but NS has the ability to not only use sub-surface energy storage solutions within these caverns, they will be essential to supporting the ambitions of intermittent energy projects on the grid. Even better, the salt "waste" can be used for sodium-ion batteries (SIBs). Furthermore, there is no recycling chain yet for the thousands of seacan sized lithium batteries NS needs, but these too can be re-used for SIBs. Furthermore, a sub-surface storage solution also provides grid security over other surface infrastructure. #Canada #Defense #Energy #CriticalMinerals #Grid #Security #Salt #CAES #Hydrogen

While lithium-ion batteries continue to dominate weight-sensitive, high-energy-density applications like long-range electric vehicles and consumer electronics due to their higher gravimetric energy density,salt-based sodium-ion batteries offer a safer, lower-cost alternative leveraging abundant raw materials and existing roll-to-roll manufacturing infrastructure (Ali Thaheem et al., 2025; Stanford STEER, 2025). Ultimately, the market is splitting with lithium-ion retaining control over mobile transport, sodium-ion scales at stationary grid storage (BESS), and supply chain security will dictate adoption across both. Stationary Grid Energy Storage (BESS): Sodium-Ion gains ground for stationary energy storage systems, footprint and weight are secondary to levelized cost of storage (LCOS), cycle life, and thermal safety. Sodium-ion eliminates reliance on copper current collectors (using aluminum for both terminals), relies on abundant soda ash/salt precursors, and operates safely over wider temperature ranges. Manufacturing Infrastructure Parity: Sodium-ion drop-in manufacturing capability is a major advantage: SIB cells can be produced using existing lithium-ion roll-to-roll manufacturing infrastructure with minimal retooling. SAILIS is exploring salt as a product from the creation of Earth batteries through geo-energy storage like Compressed Air Energy Storage (CAES) while testing for natural hydrogen or other opportunities. #salt #CAES #energystorage #renewables #wind #solar #criticalminerals #SIB #batteries #netzero
