What are the applications of your graphene solution?
Graphene is suitable for a wide range of applications, including:
What are the advantages of graphene over traditional batteries?
Enhanced Safety: Graphene is inherently safer due to their solid-state construction and lack of flammable components, eliminating the risk of thermal runaway.
Longer Lifespan: Graphene exhibits minimal degradation over time, with a lifespan exceeding 20 years, significantly longer than traditional batteries.
Higher Efficiency: Graphene boast a higher round-trip efficiency of 99.1% and offer a 100% depth of discharge, maximizing energy utilization.
Improved Environmental Friendliness: Graphene is 100% recyclable and 80% biodegradable, minimizing their environmental impact.
What is our graphene solution?
Graphene is a solid state, electrostatic, long duration energy storage solution that uses graphene, a single layer of carbon atoms arranged in a hexagonal lattice, as a key component in their electrodes. Graphene’s unique properties, such as high electrical conductivity, large surface area, and excellent mechanical strength, make it an ideal material for enhancing performance.
Is this proven technology or are we beta testing?
The ENVAULT Cabinet isn’t experimental technology—it’s been deployed globally in mission-critical applications from remote telecom sites in extreme environments to utility-scale installations powering essential infrastructure. Our technology has a decade of field performance data demonstrating reliability under real-world conditions. You’re investing in proven performance, not unproven promises.
What’s the expected ROI timeline for different applications?
ROI varies by use case, but the ENVAULT Cabinet consistently delivers faster returns than lithium alternatives:
Utilities: Peak shaving, frequency response, grid stabilization, and renewable integration enable maximum value extraction from wholesale energy markets. With the ability to cycle 4 times per day without degradation, you maximize revenue opportunities.
Data Centers: Backup power without the fire risk, space requirements, or cooling infrastructure of lithium systems protects uptime while reducing total cost of ownership. Many data center operators see 18-24 month payback periods.
Industrial Operations: Emergency backup and demand charge reduction deliver measurable monthly savings while ensuring business continuity. Typical payback ranges from 3-5 years depending on utility rate structures.
Commercial Real Estate: Energy cost optimization through time-of-use arbitrage and demand response participation improves property NOI without sacrificing tenant safety—strengthening asset value and lease competitiveness.
How does this help with our ESG and sustainability commitments?
The ENVAULT Cabinet positions your organization ahead of evolving environmental regulations while supporting ESG commitments that matter to stakeholders and customers. The system is 100% recyclable and 80% biodegradable—eliminating the toxic disposal concerns and supply chain ethics issues associated with lithium mining. This isn’t greenwashing; it’s genuine environmental stewardship that strengthens your corporate responsibility profile.
Does the system require climate control infrastructure?
No. This is where the ENVAULT Cabinet delivers major operational cost savings. The system operates reliably across a temperature range of -22°F to +140°F (-30°C to +60°C) without supplemental heating or cooling. This eliminates infrastructure complexity, reduces ongoing HVAC costs, and eliminates seasonal performance degradation. Your energy storage maintains peak performance whether installed in Arizona summer heat or Minnesota winter cold.
Will this system affect our insurance premiums or require special safety infrastructure?
Actually, quite the opposite. The ENVAULT Cabinet’s non-flammable, zero-propagation design eliminates the insurance premiums, fire suppression requirements, and safety protocols that burden lithium installations. With no volatile chemicals, no thermal runaway risk, and no explosion potential, your facilities, your people, and your balance sheet remain protected. Many clients see insurance cost reductions after switching from lithium to ENVAULT technology.
What are the total deployment costs compared to lithium systems?
The ENVAULT Cabinet’s capital efficiency creates significant advantages. Our skid-mountable design enables rapid deployment—up to 12 units per 40-foot skid delivering 5.2MWh in a fraction of the footprint required by conventional systems. Plug-and-play commissioning is measured in hours, not days, which means faster time to value and dramatically reduced installation costs. You avoid the extensive site preparation, concrete pads, and complex integration that inflate lithium installation budgets.
How quickly can the ENVAULT Cabinet respond to power disruptions?
The ENVAULT Cabinet delivers nanosecond response time, which is critical when power disruption costs your business thousands per minute. Unlike battery systems that require milliseconds to respond, our solid-state architecture provides instantaneous power delivery with no lag—protecting sensitive equipment and maintaining business continuity without the cascading failures that can occur with slower backup systems.
In utility-scale and commercial applications where cycle count and duration fall within 2-4 hour ranges, LFP consistently delivers the lowest total cost of ownership. Typical containerized systems deliver 4.0-5.0 MWh per container at approximately 2.5 MW power capacity, optimizing the balance between energy capacity and power delivery that most grid applications require.
When your business model depends on arbitrage—buying power at off-peak rates and selling during peak demand—every dollar per kWh matters, and LFP’s cost structure sets the industry standard.
CFOs and project finance teams need risk predictability. LFP technology provides exactly that. With thousands of operational installations and decades of field data, financial institutions can model performance, degradation, and residual value with confidence. This translates to competitive financing rates, established insurance markets, and predictable warranty structures—all backed by manufacturers with strong balance sheets.
LFP systems achieve 92-95% round-trip efficiency, meaning minimal energy loss during charge-discharge cycles. This efficiency remains stable across the system’s operational life, typically delivering 10,000+ cycles at 70% depth of discharge before reaching 80% state of health.
For applications involving multiple cycles per day—such as frequency regulation combined with peak shaving—this cycle life becomes mission-critical. Systems can perform daily cycling for well over a decade, covering initial financing periods and extending into cash-flow positive operation.
