World’s first hydrogen-powered off-grid data centre announced

‘Data Centre-as-a-Service’ pioneer, ECL, has announced the launch of what it claims is the world’s first modular, sustainable, off-grid data centre that uses green hydrogen as its primary power source. The company further claims to be able to deliver data centres in one megawatt (MW) blocks that can achieve 99.9999 per cent uptime.
While other data center providers have deployed hydrogen fuel cells as backup power supplies, and with some conducting trials of systems forecast for production delivery in three-to-five years, ECL asserts that it is the first provider to deliver a fully-green hydrogen-powered data centre. This leapfrog innovation is enabled by bringing together several disruptive technologies including green hydrogen-based power generation, battery energy storage and highly reliable power architecture without dependence on the utility grid.
ECL also said that its cooling innovations enable much higher density-per-rack than traditional data centre providers, a strong benefit given the increasing per-server power consumption driven by accelerating chip and system density. Water created as a by-product of hydrogen-based power generation is used to cool ECL’s server racks, eliminating the need for external water sources. Combining this with proprietary rear door heat exchange technology results in lower Power Usage Effectiveness (PUE) ratios than any other colocation data centre provider.

Calculate Data Centre Cooling Requirements

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) develops and publishes thermal and humidity guidelines for data centers. The latest edition outlines the temperatures and humidity levels at which you can reliably operate a data center based on the equipment classification.
In the most recent guidelines, ASHRAE recommends that IT equipment be used with the following:
– Temperatures between 18 and 27 degrees C or 64 and 81 degrees F;
– dew point -9 degrees C to 15 degrees C; and
– relative humidity of 60%

How to calculate data center cooling requirements

General calculation you can start with to get a baseline British thermal unit (BTU) cooling size:
(Room square footage x 20) + (IT equipment watt usage x 3.14) + (Active people in the room x 400)

To Convert BTU/hour in watts, multiply by 0.293
To Convert Watts into BTU/hour, multiply by 3.41
To Convert Tons into watts, multiply by 3530
To convert Watts into Tons, multiply by 0.000283

What is Digital Twin?

This article is taken from What is a digital twin? A real-time, virtual representation

Digital twins are real-time, virtual representations of objects, processes, and systems. While digital twins can represent purely digital things, they most frequently serve as a bridge between the physical and digital domains. For example, a digital twin could provide a digital view of the operations of a factory, communications network, or the flow of packages through a logistics system.

“The implementation of a digital twin is an encapsulated software object or model that mirrors a unique physical object, process, organization, person, or other abstraction,” according to Gartner. “Data from multiple digital twins can be aggregated for a composite view across a number of real-world entities, such as a power plant or a city, and their related processes.”

The Future of Power-Efficient Datacenters

Submer is not only obsessed with Immersion Cooling, but also looks at the entire ecosystem surrounding datacenters for possible points of optimization. In this educational and informative webinar, we were joined by John Laban, from the Open Compute Project Foundation (OCP).

John helped us identify all points of electricity waste in the delivery of power to datacenters and HPC installations.
