FAQS about Data centers go diesel-free to generate energy storage

How can renewable diesel help a data center?

With data center energy consumption projected to rise, addressing backup power sustainability becomes crucial. Renewable diesel provides a bridge toward cleaner operations, helping generators maintain reliability while aligning with global carbon reduction goals.

Can a diesel backup generator decarbonize a data center?

Traditionally, these backup generators have run on fossil diesel, which is a major source of greenhouse gas (GHG) emissions. For diesel-powered backup generators, renewable diesel, also known as hydrotreated vegetable oil or HVO100, has been used by several data center operators around the world as a solution to decarbonize backup generators.

Should data centers use diesel generators?

Diesel generators commit data center owners to another twenty years of fossil fuel dependency, and their usage by data centers runs counter to US and EU climate goals. Further, due to their non-modular nature, backup diesel generators could limit the expansion of data center operations as needs evolve over time.

Can ESS replace diesel generators in data centers?

Additionally, ESS can replace diesel generators in data centers. ESS technologies include batteries (e.g., lithium-ion), flywheels, and compressed air energy storage. Among these, batteries, specifically Battery Energy Storage Systems (BESS), are the most common.

Are battery energy storage systems a viable alternative to diesel gensets?

As renewable energy systems proliferate, the more cost-effective, sustainable, and versatile alternative to diesel gensets is a battery energy storage system (BESS), which are positioned to change the way data centers are powered.

Do data centers use a backup generator?

However, data centers consume a significant amount of energy, and a portion of that energy is used to power backup generators. Traditionally, these backup generators have run on fossil diesel, which is a major source of greenhouse gas (GHG) emissions.

How much does a data center flywheel cost?

Therefore, over the lifetime of the data center, an inefficient flywheel compared to a battery system could cost the data center owner up to as much as an extra $306,000 (1.8% x $17 Million). Some flywheel technologies such as high speed composite, frictionless vacuum-encased flywheels can demonstrate higher efficiencies.

What are the potential applications of flywheel technology?

Flywheel technology has potential applications in energy harvesting, hybrid energy systems, and secondary functionalities apart from energy storage. Additionally, there are opportunities for new applications in these areas.

What makes flywheel energy storage systems competitive?

Flywheel Energy Storage Systems (FESSs) are still competitive for applications that need frequent charge/discharge at a large number of cycles. Flywheels also have the least environmental impact amongst the three technologies, since it contains no chemicals.

How does a flywheel system store energy?

A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical or mechanical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored energy. The amount of energy available and its duration are governed by the mass and speed of the flywheel.
