Does energy consumption affect drone performance?
There are several optimization models for drone or truck-drone routes or drone delivery systems that only indirectly consider energy consumption as a set constraint on drone endurance (flight time) or range (flight distance) (e.g., Murray and Raj (2020), Chiang et al. (2019), and Kitjacharoenchai et al. (2020)).
Can hybrid electric fuel cell-powered drones improve energy management?
This paper deals with hybrid electric fuel cell-powered drones energy management while targeting hydrogen saving and power supply system efficiency improvement. In this context, a commercially available quadcopter powered by the Intelligent Energy 650W power module is adopted as a case study.
How do drones work?
For optimal performance and endurance, drones often employ hybrid power supply architecture systems that use some combination of fuel cells, batteries, solar cells, and supercapacitors.
What power sources can be used to power drones?
Fuel cells, batteries, solar cells, and supercapacitors are examples of power sources that may be combined in a hybrid power architecture. To enable today’s drones (and those of the future) to work efficiently, the appropriate energy management system must be selected based on optimal and accurate modeling techniques.
How can we model drone energy consumption?
An alternative approach for modeling drone energy consumption relies on a component model derived from helicopter operations, under the assumption that the power consumed during level flight, takeoff, or landing is approximately equivalent to the power consumed while hovering.
How do drones use hybrid power?
To optimize these systems, drones often employ a hybrid power supply system architecture to boost endurance and performance. Fuel cells, batteries, solar cells, and supercapacitors are examples of power sources that may be combined in a hybrid power architecture.

How will Fiji achieve low emission development?
Under the BAU Unconditional scenario: Open fire cooking is completely replaced with LPG, kerosene, and electric stoves by 2030. The following are considered priority actions in Fiji’s energy sector towards achieving low emission development in the next three scenarios. Energy eficiency measures76 are implemented economy-wide including:
How can the private sector support low carbon development in Fiji?
Capacity Building in the Private Sector. This will be key to ensure that low carbon development becomes a core part of Fiji’s business as usual. The private sector must be engaged to support long-term capacity building and the development of new businesses and services relevant to the implementation of the LEDS. Knowledge Management.
How expensive is geothermal exploration in Fiji?
Geothermal exploration is expensive (on average USD 4 million/MW) and Fiji will surely require external financing. Other equally expensive renewable energy resources, like wave energy, tidal energy, and OTEC, will also be investigated.
Can Fiji develop geothermal energy?
To take this effort further, it will be necessary for Fiji to explore other renewable energy technologies, like wave and tidal energy. According to the available literature,71 72 there is excellent potential for geothermal energy development in Fiji. However, developing this resource would require extensive exploratory work at significant expense.
How can Fiji achieve net zero and net negative emissions?
Introduction of more sustainable practices for commercial agriculture will be important in enabling Fiji to reach net zero and net negative emissions in the AFOLU sector as outlined in section 4.6. Commercial forestry and agriculture also play an important role in avoiding emissions in the electricity sector.
