Why data centres should care about atmospheric chemistry

Data centres are multiplying to satisfy the world’s appetite for computational power, driven by AI and other emerging technologies. The outcome has been an unprecedented surge in energy demand and greenhouse gas (GHG) emissions. Here, Alexander Krajete, CEO at emissions treatment specialist Krajete, explains why data centres must look beyond their direct carbon footprint and adopt a holistic approach to multi-emission capture and valorisation: What's changed? Data centres once had a modest footprint, accounting for under 1% of global GHG emissions, according to the International Energy Agency. But rising demand from AI, streaming, and blockchain is set to more than double their energy use from 415 TWh in 2024 to 945 TWh by 2030. Some tech giants share these predictions. Google stated in its 2024 Environmental Report that “in spite of the progress we're making, we face significant challenges that we’re actively working through. In 2023, our total GHG emissions increased 13% year-over-year, primarily driven by increased data centre energy consumption and supply chain emissions.” A holistic approach to data centre sustainability Some leading tech companies claim to have purchased or generated enough renewable electricity to match 100% of their operational energy consumption. As the IEA notes, buying renewable energy or certificates doesn’t guarantee a data centre runs on clean power 24/7 due to the intermittency of renewables and potential mismatches in location or grid. A more accurate, holistic calculation also includes indirect emissions throughout the supply chain — the so-called scope three emissions. These include mining raw materials like copper, silicon, and lithium - used in a data centre’s server racks - or the production of building materials like aluminium, steel, and concrete. Complying with new sustainability regulations Although not specifically aimed at data centres, the EU’s Corporate Sustainability Reporting Directive (CSRD) requires organisations, including tech companies, to report on their sustainability performance, including scope one, two, and three emissions. In addition, in 2024, the European Commission adopted legislation specifically aimed at “establishing an EU-wide scheme to rate the sustainability of EU data centres.” To comply with these new legal obligations, data centre operators must examine their environmental footprint holistically. Why atmospheric chemistry matters to data centres Although reducing the amount of CO2 in the atmosphere remains vital, we must also address other gases that can harm our ecosystems and climate. These chemicals include nitrogen oxides (NOX), carbon monoxide (CO), hydrogen sulphide (H2S), sulphur oxides (SOX), hydrocarbons, and various metals. Once released, these gases can react with one another, leading to secondary pollutants. The consequences of these are yet to be fully understood. They originate from combustion-heavy sectors like mining, cement, and energy, all contributors to scope two and three emissions. Traditionally, there have been two ways of capturing atmospheric pollutants. Take CO2 as an example. The sacrificial method uses limestone to remove CO2 and other gases, creating non-reusable carbonates. The regenerative amine-based method produces reusable amine carbamates but emits harmful, amine-based degradation products. Advanced adsorption is a low-energy, low-emission regenerative process that captures and valorises emissions at temperatures below 100°C, far lower than the 150–200°C required for amine-based methods. Pollutant gases weakly bind to a complex inorganic filter, allowing for easy separation. It can be applied at the exhaust point of any combustion process, such as cement factory chimneys or stationary diesel engines. By supporting the adoption of advanced adsorption technology throughout their supply chains, data centres can address their scope two and three emissions more effectively and meet their sustainability goals. Multi-emission capture is the key to sustainable data centres Thanks to innovative technologies like advanced adsorption, we can go beyond capturing and neutralising pollutants like nitrogen oxides. We can also transform these emissions into valuable by-products like fertilisers, supporting a circular economy. As the world’s insatiable demand for data grows, data centres must adopt holistic sustainability strategies that withstand the test of time. Multi-emission capture must be part of the solution, enabling data centres to balance the growing need for powerful AI with the needs of our planet.

BSRIA first UKAS-accredited provider for BTS 4/2024

BSRIA, a consultancy and testing organisation, has become the first organisation to receive UKAS accreditation in accordance with BTS 4/2024 for airtightness testing of Raised Access Plenum Floors (RAPFs), following a successful ISO 17025 audit earlier in 2024. The accreditation formally extends BSRIA’s scope of approved activities and introduces an industry-recognised methodology for testing RAPFs, which play a key role in airflow management in data centres. Chris Knights, BSRIA Building Performance Evaluation Business Manager and lead author of BTS 4/2024, comments, “The UKAS accreditation ensures we continue to provide independent testing to the highest standards of quality, repeatability, and traceability. "This is a significant advancement, enabling the industry to adopt a dedicated standard that supports higher-performing building services for owners and operators.” BTS 4/2024 standard The accreditation follows the introduction of BTS 4/2024 Airtightness Testing of Raised Access Plenum Floors, which sets out a methodology for measuring RAPF air leakage. The standard is designed to support efficient airflow management by ensuring conditioned air in underfloor voids is directed to the intended occupied areas rather than escaping through cavities, risers, stairwells, or other adjacent spaces. RAPFs are widely used in modern construction, particularly in data centres, where optimised airflow is important for both cooling performance and energy efficiency. BTS 4/2024 supersedes previous guidance, BG 65/2016 Floor Plenum Airtightness – Guidance and Testing Methodology, and incorporates clearer guidance and refined testing processes developed in response to industry feedback. Chris continues, “An effectively constructed and sealed raised access plenum floor is essential for achieving the air distribution performance intended during the design phase. "The methodology in BTS 4/2024 provides clear criteria and a step-by-step process for verifying as-built performance. "With increasing demand for high-performing environments such as data centres, specifying BTS 4/2024 supports effective air distribution and helps ensure RAPFs deliver on design intent.”

Microchip launches Adaptec SmartRAID 4300 accelerators

Semiconductor manufacturer Microchip Technology has introduced the Adaptec SmartRAID 4300 series, a new family of NVMe RAID storage accelerators designed for use in server OEM platforms, storage systems, data centres, and enterprise environments. The series aims to support scalable, software-defined storage (SDS) solutions, particularly for high-performance workloads in AI-focused data centres. The SmartRAID 4300 series uses a disaggregated architecture, separating software and hardware elements to improve efficiency. The accelerators integrate with Microchip’s PCIe-based storage controllers to offload key RAID processes from the host CPU, while the main storage software stack runs directly on the host system. This approach allows data to flow at native PCIe speeds, while offloading parity-based functions such as XOR to dedicated accelerator hardware. According to internal testing by Microchip, the new architecture has delivered input/output (I/O) performance gains of up to seven times compared with the company’s previous generation products. Architecture and capabilities The SmartRAID 4300 accelerators are designed to work with Gen 4 and Gen 5 PCIe host CPUs and can support up to 32 CPU-attached x4 NVMe devices and 64 logical drives or RAID arrays. This is intended to help address data bottlenecks common in conventional in-line storage solutions by taking advantage of expanded host PCIe infrastructure. By removing the reliance on a single PCIe slot for all data traffic, Microchip aims to deliver greater performance and system scalability. Storage operations such as writes now occur directly between the host CPU and the NVMe endpoints, while the accelerator handles redundancy tasks. Brian McCarson, Corporate Vice President of Microchip’s Data Centre Solutions Business Unit, says, “Our innovative solution with separate software and hardware addresses the limitations of traditional architectures that rely on a PCIe host interface slot for all data flows. "The SmartRAID 4300 series allows us to enhance performance, efficiency, and adaptability to better support modern enterprise infrastructure systems.” Power efficiency and security Power optimisation features include automatic idling of processor cores and autonomous power reduction mechanisms. To help maintain data integrity and system security, the SmartRAID 4300 series incorporates features such as secure boot and update, hardware root of trust, attestation, and Self-Encrypting Drive (SED) support. Management tools and compatibility The series is supported by Microchip’s Adaptec maxView management software, which includes an HTML5-based web interface, the ARCCONF command line tool, and plug-ins for both local and remote management. The tools are accessible through standard desktop and mobile browsers and are designed to remain compatible with existing Adaptec SmartRAID utilities. For out-of-band management via Baseboard Management Controllers (BMCs), the series supports Distributed Management Task Force (DMTF) standards, including Platform-Level Data Model (PLDM) and Redfish Device Enablement (RDE), using MCTP protocol.
