10 innovations related to renewable energies about to be launched or just on the market. Many of them will be very popular in the years to come and will change the way we produce energy.
- Printed solar cells.
- Floating marine wind turbines.
- Photovoltaic solar tiles.
- Solar spheres that generate energy even with the moon.
- Solar balloons for refugee camps.
- Solar panels inspired by the Japanese technique of kirigami.
- Street lighting that eliminates mosquitoes.
- Hydricity. How to produce electricity and hydrogen at the same time.
- Store renewable energy in compressed air balloons underwater.
- Generate wind power with kites.
Printed solar cells.
Unlike most solar panels, which use silicon cells, solar inks can be printed on plastic rolls up to a size of A3. The ink can be applied by a variety of methods, including a spray coat.
Lightweight, flexible and inexpensive, solar ink can be applied to a wide range of materials and devices.
The technology is ready for low power applications, although it falls short of the performance standards of used silicon-based devices and is still much less efficient.
Floating marine wind turbines.
Scotland will soon have the world’s largest floating wind farm, after the government approved the project a few weeks ago.
It will be five 6 MW floating offshore wind turbines, interconnected with cables and secured to the ocean floor via an anchoring system, it will be the first in UK waters and is expected to generate enough electricity for 20,000 homes.
Its advantage is the lower cost compared to traditional offshore wind power.
Photovoltaic solar tiles.
An interesting sustainable bet, similar to conventional tiles, which integrate mini solar panels inside. Currently on sale, most are ceramic and have 4 photovoltaic cells, the installation goes under the roof of the converter.
Solar spheres that generate energy even with the moon.
Rawlemon is a sphere-shaped lens that generates solar energy. Its system of concentration and amplification of solar rays allows it to be 70% more efficient than traditional solar panels. According to its creator, solar spheres are the most important innovation in the field of solar energy since the invention of photovoltaic panels.
During humanitarian disasters, electricity production is an immediate priority for relief teams. In refugee camps, which are often located in remote locations far from access to the electricity grid, diesel generators are used the most.
Today, a team of French designers has found an ecological solution: solar balloons.
Solar Zephyr balloons have a diameter of 4 m and could provide sufficient power for 50 people, a field hospital or a telecommunications facility. Electricity is sent to earth where it can be stored in a battery or used immediately.
As you might have imagined, its uses can be many besides refugee camps or natural disaster support.
They are currently raising funds to build their first prototype which should be ready in 2017.
Solar panels inspired by the Japanese technique of kirigami.
Solar panels that can follow the movement of the sun are known to capture much more energy, but this is not a new innovation. The technology used today can be cumbersome, cumbersome, expensive, and can only be used in certain types of facilities.
Today, researchers are developing a solution, inspired by kirigami, the Japanese art of paper cutting. After working with paper artist Matt Shlian, Max Shtein and his team at the University of Michigan created a solar panel design in which individual elements can be moved around each other. They believe that it would be easier to install than conventional panels and that they can be made from cheaper and lighter materials.
Street lighting that eliminates mosquitoes.
Malaysian researchers have created a light that doesn’t just fight climate change; it also fights diseases transmitted by mosquitoes.
This street lamp uses LED technology and a hybrid system with a solar panel and an integrated wind turbine. It incorporates a system that attracts mosquitoes and eliminates them.
Hydricity. How to produce electricity and hydrogen at the same time.
Swiss and American scientists have designed a system capable of producing both electricity and hydrogen, Hydricity. The ability to produce hydrogen and electricity is a big step forward in the use of solar energy, as energy could be produced efficiently day or night.
Hydricity seeks to make solar thermal energy more efficient, reaching levels of 46%.
Store renewable energy in compressed air balloons underwater.
The concept of Hydrostor is quite simple: when the balloon is anchored underwater, at least 25 meters deep and ideally 100 meters or more, the weight of the water naturally puts the air under pressure, allowing more air to flow out. enter, and therefore so much energy, to be stored in a certain volume. At depths greater than 500m, the cost of the type of storage becomes negligible compared to the costs of the energy conversion machines.
Generate wind power with kites.
Makani is a Google project to generate wind power using specially designed kites. This technology can produce 50% more energy with only 10% of the costs required by traditional wind turbines.
The kites are connected by cables to the ground stations. It can generate a power of 600kW once it is high enough. They can also take advantage of much stronger wind currents and thus generate more energy.
