We Turn Data Centers into Energy Plants

Most data centers waste energy. We turn that waste into heat – and reduce CO₂ emissions by 100%.

We Build Data Energy Centers®

Traditional data centers are expensive, inefficient, and harmful to the environment. At T.loop, we believe there's a better way.

Our centers don’t just store data – they power the future. By transforming waste energy into reusable heat, and optimizing every system from cooling to backup, we deliver:

30%

LOWER heat costs

100%

Reduced CO₂ emissions

30MW

Data Capacity

The T•Loop Concept

T.loop integrates the energy needs of IT, real estate, and the power grid into one circular system – where nothing is wasted, and everything gives back.

Heat Recovery System & Hydrogen Fuel Backup

We recover and reuse all waste heat. Our hydrogen-powered backup is clean, quiet, and completely emissions-free.

Liquid
Cooling

Whenever possible, we use liquid cooling instead of traditional air systems. It’s more efficient, and cuts electricity use by up to 30%.

Self-sustaining UPS & Batteries

Our backup power doesn’t just wait for emergencies. It actively supports the power grid through peak shaving and grid balancing

Built for the Future of Computing

T.loop Data Energy Centers® are purpose-built for the next generation of digital infrastructure.

All of our centers are designed to handle the demands of AI, Edge, and high-performance computing (HPC) – without the energy waste or emissions.

High-Speed Connectivity

Every T.loop site is equipped with fiber and multiple ISPs – ensuring fast, reliable connections, with seamless data flow and low latency.

Flexible Colocation Options

From individual racks to private data halls, we offer scalable colocation services tailored to your capacity, security, and compliance needs.

Sustainability by Design

The heat we generate is 100% reused. Our colocation model brings together data users, energy consumers, and suppliers in on e circular system.
