Data storage and processing demand is skyrocketing in our increasingly digital world. Data centres are the backbone of modern society, from cloud computing and artificial intelligence to the Internet of Things (IoT) and high-definition streaming. However, this growth comes with a significant environmental cost. Data centres consume approximately 1% of the global electricity supply, contributing substantially to carbon emissions.
As businesses and consumers rely more on digital services, the imperative to mitigate the carbon footprint of our digital infrastructure has never been more critical. Enter green hydrogen—a promising, renewable energy source poised to revolutionise the energy landscape of data centres and IT infrastructure.
Understanding Green Hydrogen
Green hydrogen is produced through the electrolysis of water. This process splits water molecules into hydrogen and oxygen using electricity from renewable energy such as wind, solar, or hydroelectric power.
Unlike grey hydrogen, which relies on fossil fuels and emits significant carbon dioxide (CO₂), or blue hydrogen, which incorporates carbon capture and storage (CCS) technologies, green hydrogen offers a sustainable and environmentally friendly solution. Its production ensures the entire lifecycle is carbon-neutral, aligning perfectly with global efforts to combat climate change and reduce greenhouse gas emissions.
The Growing Demand for Data Centers
Digital transformation across industries has increased exponentially in data generation and consumption. By 2025, global data creation is expected to reach 175 zettabytes, driven by the proliferation of smart devices, expansion of cloud services, and integration of data-driven decision-making processes.
This surge necessitates the expansion of data centres and IT infrastructure, which, while essential for supporting digital services, also amplifies energy consumption and environmental impact. Traditional data centres rely heavily on non-renewable energy sources, exacerbating their carbon footprint and resource depletion.
How Green Hydrogen Reduces Emissions
Green hydrogen offers a transformative approach to decarbonising IT operations. By replacing fossil fuel-based energy sources with hydrogen-powered systems, data centres can substantially reduce CO₂ emissions.
Hydrogen fuel cells convert hydrogen into electricity with efficiencies typically ranging between 40-60%. While some sources claim efficiencies of up to 70%, real-world performance can vary based on factors such as cell design, operating temperature, and load conditions. Ongoing advancements in fuel cell technology aim to improve these efficiency rates over time. They also have zero carbon emissions when produced using renewable energy. This shift reduces direct emissions from power consumption and backup generators and minimises indirect emissions associated with IT infrastructure manufacturing and maintenance.
Additionally, green hydrogen serves as an excellent energy storage medium, balancing the intermittency of renewable energy sources and ensuring a reliable power supply for data centres.

Case Studies: Leading the Green Hydrogen Movement
Real-world examples of companies successfully integrating green hydrogen provide valuable insights into practical applications and benefits:
- Microsoft’s Sustainable Data Centers Initiative
Microsoft has committed to becoming carbon-negative by 2030. As part of this effort, the company has recently announced a groundbreaking pilot project in partnership with ESB to replace its backup diesel generators with zero-emission green hydrogen for its data centre in Dublin, Ireland. This initiative aims to eliminate the carbon footprint associated with traditional backup power systems, enhancing the data centre's overall sustainability and resilience.
By leveraging green hydrogen, Microsoft not only reduces its reliance on fossil fuels but also sets a precedent for the adoption of cleaner backup power technologies in the IT infrastructure sector.
This pilot is the first in Europe and will supply up to 250kW of clean energy to Microsoft’s Dublin campus over eight weeks. The hydrogen fuel cells convert stored green hydrogen to electricity, with water as the only by-product, significantly reducing carbon emissions and eliminating harmful air pollutants.
This initiative showcases Microsoft's dedication to replacing diesel generators with hydrogen-powered systems. According to Eoin Doherty, Vice President of Microsoft Cloud Operations + Innovation in EMEA, this project demonstrates how zero-emission hydrogen can help advance sustainability in data centres and across sectors.
In addition to this pilot, Microsoft continues to lead the way in integrating green hydrogen into its operations globally. This Dublin project builds on previous efforts in the U.S. and aligns with Microsoft's broader goals of decarbonising its infrastructure, including its cloud and AI platforms.
