After the expressway photovoltaic, the airport will also develop solar power gen

Large international airports carry tens of thousands of passengers every year, and at the same time they need to consume a lot of electricity to maintain the operation of the airport. Therefore, in recent years, airport operators have been actively trying to supplement the electricity supply of the airport with renewable energy to prevent unexpected situations.

The airport power supply crisis received so much attention due to the power outage at Hartsfield-Jackson Airport in Atlanta in December 2017.  The blackout caused more than 1,000 flights to be canceled or delayed, causing Delta Airline, Georgia's major commercial airline, to lose nearly US$ 50 million.

As the main cables and backup cables of Hartsfield-Jackson Airport all passed through the same tunnel, the fire in the tunnel at that time directly paralyzed the two cables, resulting in the blackout.

For this reason, the aviation industry began to actively seek reliable alternative energy sources to deal with similar emergencies.  Renewable energy has thus entered the eyes of airport operators.

Can airports use renewable energy sources such as wind energy and solar energy more reliably? According to research by the National Academy of Sciences (NAS), one of the benefits of the airport's switch to renewable energy is "direct control of the infrastructure for wind and solar power generation."

Energy can be generated on site, which means that the aviation industry will be less affected by fluctuations in international energy prices and may be a great boon to the aviation industry.

NAS has conducted research on a number of renewable energy sources, including solar energy, wind energy, biomass energy, geothermal energy and hydropower. Finally, it is found that solar energy is the most feasible, and the solar array can be placed in the open space around the airport runway. According to the research report of the National Renewable Energy Laboratory (NREL), there are about 800,000 acres of vacant land in domestic airports in the United States for solar arrays, which can produce about 116,000MW of solar energy, equivalent to the electricity generated by 100 coal-fired power plants.

Currently, there are 50kW solar arrays at Gatwick and Birmingham airports in the UK, while India's top four busiest Cochin international airports are currently equipped with 13.1MW solar arrays, making them 100% solar airports. In addition, four airports in the United States have installed solar energy equipment.

However, solar arrays placed near airport runways have some disadvantages. One is that the reflection of solar panels may affect the vision of the pilots. In addition, the hot air on the solar panels will change the air convection and make the takeoff and landing of the aircraft unstable.

In response to these two problems, the U.S. Federal Aviation Administration and airports have made some adjustments to the location of solar array emissions. This also shows that the development of solar energy in the airport is not as simple as casually placing several groups of solar arrays!

At present, many countries have tried and put into practice the application of solar power generation in airports in the world. As one of the countries with the fastest development in power generation application in global solar, China will definitely move solar power generation from highways to airports in the future. Let's all wait and see
