NEC and NTT develop energy-saving cooling system using greener HFO refrigerant

Japan-based NEC and NTT Communications have developed an air cooling system which they claim slashes air conditioning power consumption in data centres.

The energy-saving system is the first to use a new low-pressure refrigerant called R1224yd, developed by Japanese manufacturer AGC and originally designed for centrifugal chillers, which in addition to being more energy-efficient is more environmentally friendly than other commonly-used refrigerants.


Microsoft powers data centre servers with hydrogen fuel cells for 48 hours

Microsoft has continuously powered a row of data centre servers for 48 hours using hydrogen fuel cells, the tech giant announced Monday.

Microsoft powered a row of data centre servers for 48 hours using a 250-kilowatt fuel system built by Utah-based developer Power Innovations, based on a concept system tested at the US National Renewable Energy Laboratory in 2018.

The system uses proton exchange membrane or PEM hydrogen fuel cells which combine hydrogen and oxygen to produce water vapour and electricity.


Microsoft to ditch diesel backup power by 2030 to meet carbon negative commitment

Microsoft has detailed how it plans to meet its ambitious goal of becoming carbon negative by 2030.

The pledge, made by Microsoft CEO Satya Nadella, President Brad Smith, and Chief Financial Officer Amy Hood in January, is the most sweeping carbon commitment made by any company.

At the time, Microsoft said it was working on an initiative to reducing its carbon, water, waste footprints and promote biodiversity, but offered few details on what this initiative would entail.


Driving forward air standards with data

Recently, the Committee on Climate Change published its annual Progress Report to Parliament providing new advice to the Government in reducing UK emissions. It assessed the government’s climate change mitigation activity and outlined measures to accelerate the transition to achieving Net Zero by 2050.

There have been ambitious policies introduced in an effort to reach the Net Zero target but have not been as forthcoming as we have hoped. In fact, in 2019 the UK had reduced its emissions by 3-4% but this rate of reduction is simply not high enough to meet our climate goals.


In search of eternal life for IT hardware

Circular economy is all about creating a roadmap from ‘cradle to grave’ to ‘cradle to cradle’. The ideal is to create a system that is regenerative by design, which minimises harmful emissions and turns waste into manufacturing resource. ‘Eternal life’ for our equipment is the great modern-day challenge, but it is by no means an impossible dream.
