Controllis launches carbon neutral power solution for off-grid and poor-grid telecom sites

Controllis Zero offsets CO2 emissions from power production with sustainable biofuel system

Cambridge 27th November 2019. Controllis, a leading supplier of hybrid power systems for mobile network operators (MNOs) and tower companies, has leveraged its experience to develop 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.

Based on Controllis' proven and 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), Controllis Zero will allow MNOs and tower companies to overcome the final 10 percent of the CO2 emissions challenge.

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.
According to the GSMA 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", explains 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."


The Controllis Zero biofuel lifecycle
• The manufacture of E100 bioethanol during the plant growth stage is carbon negative because CO2 is converted into oxygen by photosynthesis
• CO2 emissions during bioethanol fermentation and distillation are counterbalanced by ethical offset programs supported by the United Nations
• E100 bioethanol is shipped to different locations using the greenest modes of land and sea transport. The emissions for the transport phase are also offset.
• Controllis' hybrid solar lithium ion solution is the principal power source up to 90% of the time. The remaining 10% is produced by Controllis' bioethanol-powered generator
Controllis Zero also comprises powerful and secure remote monitoring and analytical tools, giving onsite and offsite maintenance teams meaningful and actionable insights into all aspects of the system's power output and performance levels in real time.
Controllis Zero will be commercially available from Q1 2020

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
