New weapon in fight for net zero emissions economy

Controllis, which supplies hybrid power systems for mobile network operators and tower companies, has developed a carbon neutral site power system to help support a net zero emissions economy, established by the Paris Agreement. 

The new system, Controllis Zero will allow off-grid and poor-grid sites to produce cleaner energy overall by replacing their dependency on fossil fuels with an eco-friendly biofuel alternative.

The new technology is based on Controllis’ globally deployed Modular48 DC power system, which already reduces carbon emissions by up to 90 percent by harnessing solar power and rechargeable lithium ion batteries. It will allow MNOs and tower companies to overcome the final 10 per cent of the CO2emissions challenge, the Thetford-based business says.

Controllis has been able to achieve this carbon-neutral status by considering the carbon cycle process in its entirety and adapting its unique DC generator technology to run on E100 bioethanol instead of diesel. All this is accomplished without compromising network uptime, says the company.

According to the GSMA – a trade body that represents the interests of mobile network operators worldwide – there are more than one million off-grid/poor-grid telecoms sites in use globally, which combined are generating a carbon footprint greater than countries such as Nepal, Cambodia and Cameroon. 

By leveraging the environmental benefits of biofuels and supporting ethically approved CO2 offsetting processes such as tree planting or renewable energy sources for remote communities, Controllis Zero is poised to help large Telco’s meet their legal, shareholder and green obligations.

“With global warming increasing and net zero targets looming, companies are under increasing pressure to operate in a more sustainable way,” says Simon Albury, managing director of Controllis.

“Controllis Zero has been developed with efficiency initiatives such as OFGEM’s ECO in mind and any CO2 released during energy production is offset by a carbon-neutral biofuel manufacturing process.”

• Controllis Zero will be commercially available from Q1 2020.
