Voxel Energy
Energy independent data centers with solar and repurposed batteries.
About
The best grid connection is no grid connection. Voxel captures, stores, and consumes solar energy onsite without the grid, completely bypassing utility connection delays. By leveraging the vast supply of second-life EV batteries with our novel DC microgrid architecture, we drastically reduce engineering overhead and time-to-power.

Problem & Solution
Problem/Solution Report
Problem: Hyperscale and AI data centers face rapidly rising electricity demand, water constraints, and lengthy grid interconnection timelines. These bottlenecks increase both capital and operating costs and delay time‑to‑revenue, especially in regions with limited utility capacity.
Voxel’s Solution: Voxel builds closed‑loop, off‑grid modular data centers that require no electrical utility connections or process water. The solution captures solar energy onsite, stores it in repurposed second‑life EV batteries, and distributes power through a novel DC microgrid. This architecture eliminates utility‑related expenses, shortens deployment time via prefabricated modules, and provides resilience and sustainability benefits.
Value Proposition:
- Speed: Prefabricated modules cut design, permitting, and construction timelines, enabling rapid capacity addition where grid connections are backlogged.
- Cost: By removing electricity and water utility fees, Voxel reduces operating expenses while offering modular redundancy.
- Sustainability: On‑site renewable generation and circular use of EV batteries lower carbon footprint and enhance reliability.
Strategic Fit: Industry forecasts (IEA, McKinsey) predict a doubling of data‑center electricity use by 2030, intensifying the need for power‑centric, quickly deployable solutions. Voxel’s off‑grid approach directly addresses interconnection delays and water scarcity, positioning the company to capture a growing niche of energy‑independent data‑center deployments.
Market & Competitors
Market and Competitors Report
Market Context: Global data‑center build‑out is accelerating, with JLL forecasting ~100 GW of new capacity (2026‑2030) and McKinsey projecting $6.7 trillion of cumulative capex by 2030. Electrical and mechanical systems comprise roughly half of construction costs, and IEA expects data‑center electricity demand to more than double by 2030, creating pressure for power‑centric solutions.
Key Competitors:
- ECL – Offers hydrogen‑powered modular off‑grid data‑center‑as‑a‑service units using green hydrogen fuel cells and closed‑loop water cooling.
- Exowatt – Provides solar‑plus‑storage power solutions for AI workloads, emphasizing 24‑hour solar generation.
- Edge Centres – Builds modular off‑grid edge facilities powered by on‑site wind/solar and battery backup, with grid as a secondary source.
Positioning vs. Voxel: Voxel distinguishes itself by leveraging photovoltaic generation combined with second‑life EV batteries and a DC microgrid, avoiding the logistical complexity of hydrogen supply and offering faster scalability than thermal‑storage approaches. Compared to edge‑focused providers, Voxel targets hyperscale/AI sites with higher density and stricter power‑independence requirements.
Target Customers & Advantages: Primary customers include hyperscalers, AI model developers, and enterprises needing rapid capacity in power‑constrained regions. Advantages are faster time‑to‑power, reduced utility OpEx, and sustainability credentials. Risks involve integration at high densities, second‑life battery supply chain management, and permitting for large PV/storage installations.
Overall Outlook: The convergence of soaring compute demand, grid interconnection backlogs, and sustainability mandates makes the off‑grid, renewable‑powered data‑center niche strategically significant, with Voxel well‑positioned to capture a portion of the multi‑hundred‑billion‑dollar market.
Total Addressable Market
Quantitative TAM Report
Scope: Voxel’s addressable market includes (1) data‑center facility capex for power and cooling infrastructure, (2) onsite renewable generation and storage systems, and (3) rapid modular deployments for AI‑intensive workloads.
Top‑down CapEx Outlook: McKinsey estimates $6.7 trillion of cumulative global data‑center capex through 2030, with $5.2 trillion for AI workloads. Approximately 25 % of AI‑related capex ($1.3 trillion) is allocated to “energizers” – power generation, transmission, cooling, and electrical equipment – plus about $200 billion for non‑AI, totaling roughly $1.5 trillion for power‑centric spend.
Capacity Growth & Cost Structure: JLL projects ~100 GW of new data‑center capacity (2026‑2030), representing $1.2 trillion in real‑estate value. Turner & Townsend’s construction cost index shows electrical systems account for 48‑54 % and mechanical systems 22‑33 % of build costs, underscoring the large spend on power and cooling.
Electricity Demand: IEA data centre electricity use is about 415 TWh in 2024 and is projected to double to ~945 TWh by 2030. Roughly 40 % of this demand is for computing and another 40 % for cooling, highlighting the scale of power requirements.
TAM Estimation:
- Penetration method: Assuming 10‑20 % of the 100 GW capacity adopts off‑grid, renewable‑plus‑storage solutions, 10‑20 GW of deployments could be served. At $9‑15 million per MW for shell + MEP (electrical/mechanical) spend, the power‑related portion alone could represent $70‑200 billion.
- Category share method: Capturing even a single‑digit share of the $1.5 trillion “energizers” bucket yields a TAM in the high‑tens of billions.
Overall, the TAM for energy‑independent power and cooling integrated with modular data‑center capacity plausibly ranges from $50 billion to $200 billion through 2030, depending on adoption rates and regional constraints.
