Microgrids & Alternative Fuels to Power the Future

How feasible are microgrids, and are they a better idea than the nuclear data centres hyperscalers are chasing?

Microgrids are a highly feasible solution for powering data centres, especially in regions where traditional energy grids face reliability or capacity challenges. Their modularity allows data centres to maintain operations independently of the main grid, ensuring resilience and scalability.

AVK has been at the forefront of delivering microgrid solutions, enabling data centres to integrate renewable energy sources like solar and wind while balancing reliability through HVO-powered generators or other sustainable fuels.

While nuclear-powered data centres might promise high energy density and zero carbon emissions, they remain in the exploratory phase due to regulatory, safety, and cost concerns. 

Microgrids, on the other hand, are deployable now, offering flexibility and a faster route to decarbonisation. They empower data centres to act as community energy hubs, balancing energy needs between local infrastructures and data centre operations.

The choice between these approaches depends on the specific use case. Microgrids excel in decentralization and sustainability, making them practical for diverse geographies, while nuclear might serve hyperscalers requiring vast, consistent power in specific locations.

What are some underrated alternatives to power data centres that haven’t made it to the mainstream yet?

In the search for sustainable energy solutions, alternative fuels are playing a growing role in powering data centres. Some are still considered niche but have the potential to become mainstream as technology and infrastructure improve:

Hydrotreated Vegetable Oil (HVO)

HVO is a renewable diesel fuel derived from vegetable oils and waste fats. It offers a cleaner-burning alternative to traditional diesel, reducing CO₂ emissions by up to 90% compared to fossil fuels. AVK has already integrated HVO-powered generators into microgrid solutions, providing a reliable and sustainable option for data centres.

Hydrogen

Hydrogen is emerging as a game-changing fuel for data centres, particularly green hydrogen produced via electrolysis powered by renewable energy. Hydrogen fuel cells provide clean and efficient energy, producing only water as a by-product. While still in the early adoption phase, hydrogen is expected to play a significant role in powering data centres, especially as supply chains scale.

Biogas

Biogas, produced from organic waste through anaerobic digestion, is a renewable energy source with a lower carbon footprint than natural gas. Data centres in regions with strong agricultural or industrial outputs could utilize biogas to power operations while contributing to circular economy initiatives.

Some of these fuels, particularly HVO, hydrogen, and biogas, are already making inroads into the data centre industry and could become mainstream as the infrastructure for production and distribution scales up. Hydrogen, for example, is increasingly being piloted by leading operators as part of broader decarbonization initiatives, while HVO’s compatibility with existing diesel engines makes it an attractive near-term solution.

The diversity of these alternative fuels reflects the industry’s shift toward reducing reliance on fossil fuels and embracing more sustainable, flexible power options. AVK is committed to exploring and deploying these innovative solutions as part of its journey toward a more sustainable energy future.

What does the future hold for data centres, especially with evolving power demands driven by AI adoption?

The future of data centres will be defined by their ability to scale sustainably while meeting the increasing power demands driven by AI. AI workloads, particularly training large models, require significantly higher energy inputs and more advanced cooling systems. These factors will accelerate the following trends:

Shift to Renewable Microgrids

To address growing demands, data centres will increasingly adopt hybrid microgrids that integrate renewable sources with efficient energy storage. AVK’s work on emissions-reduction-focused microgrid solutions exemplifies this direction.

Localised Energy Generation

As AI processing grows, data centres will prioritise proximity to both energy sources and end users, leading to a rise in edge data centres. AVK sees this trend driving the adoption of flexible, modular energy systems.

AI-Optimised Energy Management

AI will play a dual role as a demand driver and an efficiency enhancer, optimising energy distribution and load balancing within data centres to reduce waste and cost.

Carbon Capture Integration

To offset emissions from higher power consumption, data centres will likely integrate carbon capture technologies alongside traditional operations.

The intersection of innovation, sustainability and community integration will define the evolution of data centres, with companies like AVK driving forward-thinking solutions.

New Locations and New Availability Zones

As demand for data processing grows, new data centre locations and availability zones will emerge to bring capacity closer to end users. These will cater to the needs of edge computing and low-latency AI applications while helping to distribute energy consumption more effectively across regions.

Emerging markets and Tier 2 cities are expected to play a pivotal role in supporting this expansion.
