One of the core applications of CTS technology is in the aviation sector.
CTS technology can be used to aid the decarbonisation of aviation.
Applications for aviation
Enertechnos has worked for the past 8 years to develop a patented electricity distribution system that delivers more power with fewer losses than conventional cable can. Unlike traditional electrical cables CTS works even better at higher frequencies and over longer distances. CTS has a major advantage in 3 areas that are relevant to airports:
All airports are facing the challenges of decarbonization and everything that can be done to improve efficiency helps on the road to Net Zero. While most suppliers focus on selling one piece of efficient technology – LED lights, plug-in EV chargers, etc. Enertechnos focuses on gaining large-scale efficiency by improving the way that electrical power is supplied, distributed, and metered for the various ways it is used in the airport.
Fixed Electrical Ground Power (FEGP): achieving Net Zero
Start with a high-frequency ring main for each terminal
FEGP: the benefits
- 400Hz distribution direct to every gate from central unit
- Capital savings reducing converters
- Ground power to remote stands with CTS
- Reduce use of APUs and GPUs
- Increased resilience by providing power distribution
- Thermal recovery from centralised power electronics to heat terminals
- 85kHz ring main for wireless EV charging
- Provision of FEGP is restricted by current cabling technology to a short distance between a 50/400Hz converter and a single aircraft – typically 50 – 60 metres.
- In the event of converter failure, the gate is unserviceable, or the aircraft must use GPU or APU.
- A converter is required for every gate – with consequent low utilisation rate.
- Difficult to provide FEGP at remote stands because of distance
- CTS is effective < 5,000 metres at 400Hz (cf. < 60 metres for conventional cable)
- Far more cost-effective solution as converter can be shared between multiple aircraft
- Greater resilience to failure compared to one-to-one converter-aircraft configuration
- Far easier to extend to remote stands
- Overall capex and opex reductions from simplified design
- Potential for heat recovery from centralised converter for use in terminal heating
- Facilitates provision of power for electric PCA units at remote stands
- Enables reduction in GPU/APU use because higher availability, and so reducing carbon footprint of airport
Wireless Power Transfer (WPT) for airside fleet
Obstacles or wide-open spaces?
Airside WPT: the benefits
More space for complex routing of vehicle movements
Opportunity charging – less downtime
Smaller batteries – 30% lower vehicle costs
No cable breakages or inaccurate connections – saves man hours
Cuts potential collisions with chargers and other vehicles reversing from the unit
85kHz ring main from the central converter
Lower CAPEX on the frequency converter
Heat recovery from the central converter to heat terminals
CTS cable has lower power losses over greater distances than any other cable
Net Zero emissions on the ground is the goal for all airports
With thousands of movements of vehicles 24/7, either owned by the airports, airlines, ground handlers and many outside companies, detailed studies should be made to recommend (conclude) the most efficient and cost-effective ways to achieve these goals.
As a first stage in such a study, Enertechnos will be able to demonstrate how its unique CTS cable can effectively be used with minimal power loss, enabling multiple BEVs to be charged from one central power source with no charging ‘furniture’ allowing easier and safer vehicle movements while achieving zero emission goals.
