Case Studies
Making the case for flying electric
London Airports Centre is a Pilot training school in Essex who is focused on reducing Carbon emissions of its activities and has the ambitious goal of becoming a NetZero flight training school by 2030.
They have a fleet of electric aircraft used for their training activities as well as traditional Cessna Aircrafts.
​
They wanted to showcase using science-based data the difference in carbon emissions compared to traditional aircrafts. They were also interested in demonstrating how running electric aircrafts are not only green but also cheaper than traditional aircrafts.
​
In addition, they wanted to plan for further decarbonization by installing solar panels on the site to power the planes and further reduce emissions. To do so, they needed to understand accurately their energy profile to calculate with precision the type and number of panels needed to effectively cover all their energy needs.
Requirements
01.
Capture accurate data on electricity consumed over time
02.
Calculate CO2 emissions of flying activities.
03.
Calculate solar panels needed to meet energy needs
04.
Analyse and display Return on Investment
05.
Provide consultancy and support in solar installation
Planning for Net Zero
London Airsports Centre, deterred by high energy prices and the desire to further decarbonize asked us to use the data we had collected on their energy profile to produce a proposal for the installation of Solar panels on the roof of the hangar where the Aircrafts are parked.
01
Calculating the equipment needed and ROI
CarbonLnk was able to calculate the ROI and the costs of the panel over the duration of the panel warranty.
02
Match the Performance of the panel with the needs
We were able to understand precisely how many panels were needed to cover electricity needs and after further discussions it was agreed that we would install in excess of what was needed as the roof space allowed for it. We were able to graphically demonstrate an individualized panel performance graph.
03
Graphic display of performance
The performance of the panels is displayed graphically to show differences in outputs over the day and the year

FinDings
01.
The fuel cost of a flight with an electric plane is £6.6 compared to £15.1 and £22.7 for traditional planes ( 80hP and 110 hP ) , a difference of 78% and 109% respectively
02.
The CO2 emissions reduction of flying electric is 119% reduced ( 50.8 kgs vs 162 kgs and 203 kgs )
03.
The number of panels needed are 72 to cover the needs. the ROI is 18 months if remains on current tariff or 7 years assuming variable tariff over the years
04.
The company would need to plant 9040 trees if they wanted to offset their emissions for the year.

electricity losses in former central london hospital
Understand high electricity bills
A former hospital building now repurposed for student accommodation is experiencing higher than expected electricity bills. The building managers need to understand this discrepancy and remedy any issues that cause the bills to be higher than normal.
​
The building managers have already commissioned a company to conduct an electrical testing and analysis. It did not show any discrepancies from the existing bill reading.
They asked Lnk Technologies to test the electrical installation to provide granular and real time data on electricity consumption.
Our challenge was to obtain accurate power readings from an antiquated old system without any wiring or schematic diagrams. Like most hospitals and large infrastructures, this site had the equivalent power of an electrical substation, approx. 5 MW.
