The Black Vault Review: Is Its AI Infrastructure Ready?

The Black Vault develops physical infrastructure for AI and high-performance computing rather than selling models, applications or accelerator chips. Its stated scope includes land, power, cooling, heat recovery, network, security and the computing environment. It describes two formats: regional nodes in existing industrial buildings, generally in the 1–3 MW class, and larger campuses of 50 MW or more.

The two named sites have different levels of readiness. Quedlinburg is presented as an existing energy site with 1 MW connected, while its AI layer is still being developed. Blankenburg is the proposed campus-scale project: the site gives Phase 1 a 50 MW design basis, but the project remains in development. That makes this a potential infrastructure partner for enterprise or compute operators, not a ready-made service you can sign up for as an individual.

The company says tenants provide the accelerators. Ask whether a proposal is for powered shell, managed data-centre services or another arrangement; the project information does not define a standard service package.

The Black Vault does not publish prices, connection charges, recurring fees, minimum commitments or standard contract terms. You therefore cannot compare its cost with another data-centre provider from the published project details alone. For a large infrastructure project, a final price can depend on capacity, power arrangements, cooling, connectivity, fit-out, service levels and the length of the contract; get each item spelled out rather than relying on a headline capacity figure.

The site refers to requests for capacity, but that is not the same as confirmed availability or a binding offer. Ask for a written proposal showing the exact site and delivery date, reserved power and IT load, any one-off development or connection charges, recurring costs, indexation, deposits, cancellation rights and remedies if the project is delayed. Confirm who pays for tenant equipment and network links, and whether heat-recovery arrangements affect the commercial terms.

Until those terms are available, value cannot be rated meaningfully. Do not treat the planned capacity or infrastructure design basis as a quote or a promise of service.

The project identifies Black Vault Blankenburg GmbH as a registered German project company and says each campus is held in its own German project company. That gives a prospective counterparty a named legal entity to investigate, but registration by itself is not proof of financial strength, delivery capability or operational security. The company also says the holding funds surveying, engineering and legal work before seeking outside capital; ask for supporting documentation if that matters to your decision.

The site describes the project as designed toward KRITIS and NIS2, explicitly framing this as a pathway rather than a certification. The project information does not establish an independent security audit, a licence, or completed compliance certification. It also does not give a detailed record of completed data-centre operations or disclose the full project financing and delivery arrangements.

Before signing or transferring funds, verify the contracting entity, land and planning rights, grid status, permits, insurance, financing, security controls and the people responsible for delivery. Have your legal and technical advisers review the contracts and any evidence behind the project’s claims.

The clearest published distinction is between existing infrastructure and development plans. At Quedlinburg, the site lists 1 MW of connected capacity, a 2 MVA transformer and 450 kW of façade solar as existing, while describing the AI layer as under development. At Blankenburg, it describes cleared industrial ground and a campus design, but says the 110 kV connection for 60 MW was applied for in March 2026. An application is not an approved connection or a completed power supply.

The project also describes mine water at 10–12°C, a closed campus and rack cooling loop, and heat-export potential up to 35 MWth as design-basis information. Those are not all the same as installed, commissioned systems. The site says carrier procurement is in process and the meet-me room is planned, so connectivity arrangements also need confirmation.

Ask for dated evidence of what is built, commissioned and available at the specific site you are considering. Confirm power and network delivery milestones directly in the contract rather than assuming that a design figure is operational capacity.

There is no consumer sign-up flow described. The apparent first step for a prospective tenant or partner is to request capacity and discuss a project-specific arrangement. The published information does not set out an onboarding process, service-level agreement, standard lead time or support model, so expect to qualify the opportunity directly with the company rather than provision compute on demand.

Before sharing sensitive technical or commercial information, confirm who you are dealing with and whether a confidentiality agreement is appropriate. In early discussions, specify the intended site, required IT load, power profile, cooling needs, network routes, deployment schedule and whether you will supply your own hardware. Ask for a site-specific response that separates existing assets from planned work and identifies dependencies such as grid approval, permits and carrier procurement.

The site mentions multi-route network design and Frankfurt connectivity, but also says route development and carrier procurement are in progress. Treat redundancy, latency and delivery timelines as questions for a written technical proposal, not as settled service specifications.
