Metal trees have seven-meter canopies that capture solar energy through nanophotoelectric “leaves.” The energy will be stored in a battery located in the trunk.
The British startup SolarBotanic Trees has developed a technological innovation for charging electric vehicles. Previously, it showcased the initial prototype of these charging devices to visitors at the Expo 2020 Dubai and the Gardens by the Bay park in Singapore. Now, the company plans to build and test a full-size version of the solar trees. By the end of the year, it will begin commercial production, as reported. CNN .
According to Chris Shelly, CEO of SolarBotanic Trees, the UK is experiencing a severe shortage of charging infrastructure. Some electric vehicle suppliers offer solar panel canopies that are meant to be placed over parking spaces. However, these devices are not aesthetically pleasing, unlike SolarBotanic Trees. Mr. Shelly mentioned that his company has already received its first order for 200 of these trees.
What else is known about solar trees?
Structures with a height of 4.5 meters are quite compact. Therefore, they are easier to install in public places such as luxury hotels, shopping centers, corporate offices, and business parks that require eco-friendly innovations.
Trees from SolarBotanic will cost between £18,000 and £25,000 ($22,000 to $30,000). This is more expensive than conventional solar panels. The power output of the trees is 5 kilowatts, which is typical for a standard charging point. At this power level, charging a car with a 50-kilowatt battery from 20 to 80 percent will take almost seven hours. This speed is more suitable for situations where the vehicle is parked for an extended period.
The startup is currently planning to develop a smaller and more affordable version with a power output of 3.2 kilowatts. According to Chris Shelley, this model will cost between £10,000 and £15,000 ($12,000 to $18,000). It will fit organically into university campuses, shopping centers, and more. It can also be used for LED lighting, electronic advertising, and charging smartphones and laptops.
Each tree will be equipped with an energy storage and power management system, controlled by artificial intelligence. Such a system can connect several trees together to form local microgrids. It can also connect the tree to the main grid, where excess energy will be returned.
To reduce dependence on the grid, the startup will place an energy storage battery in the trunk of a tree. This way, it can be used during the dark hours of the day.
The company SolarBotanic Trees has raised £340,000 ($420,000) to begin mass production by the end of the year, following tests of a full-size prototype. By 2025, the startup plans to build at least 1,000 trees per year.
Mr. Shelley announced that the trees will be planted in the United Kingdom, and then in countries across Europe and North America.
The invention will not go unused. As noted by the UK Climate Change Committee, by the end of 2032, the rapidly growing electric vehicle fleet will need an additional 325,000 charging points.
