Green Tech to watch in 2023

From transparent solar panels to fusion energy breakthroughs, a great deal of time, talent, and money is being invested in developing more sustainable technologies. We’ve compiled a list of some of the ones we’ll be watching in 2023.

Let’s start our summary with the original green energy source: the sun.

Solar energy has long been considered a major source of rejuvenation, and it has been considered competitive with conventional power sources, but it does come with a couple of caveats. It is worth noting that the sun does not always shine. And even when it does, most commercial solar panels are not as efficient as wind turbines.

However, efforts are underway to find new ways of making, applying and deploying solar panels that can help them meet a larger portion of our energy needs.

One of the wildest developments in solar energy that I’ve come across to date is the dawning of transparent solar panels that can be applied like film over windows or other surfaces to get power. two Companies are pushing this kind of technology forward: ubiquitous energy and solar windows.

Both aim to create partnerships with other companies rather than sell directly to consumers. Clear solar panels will likely be offered as an upgrade option if you are looking to install some new windows in your home or office, or they may be offered as an addition to your vehicle.

Speaking of cars, some electric cars have also begun to combine with ordinary cars Solar panels as a major feature. Every solar electric vehicle still needs to be plugged in to charge for long-haul trips, but you may be able to achieve up to 40 miles a day on short trips from solar power alone depending on your vehicle, where you park it, and what type of solar pack it has. on her.

A handful of the solar cars I’ve come across, including the Aptera, Sono Sion, and Lightyear 0, are It is designed to be lighter in weight, to make the most of the installed solar energy.

Capturing the power of the sun is one thing, but there are also people who are actually trying to clone the power of the sun here on Earth. I’m talking about fusion energy, which seeks to fuse elements together to generate energy, similar to the reactions that take place inside our star’s massive celestial furnace.

Recently, a breakthrough occurred at Lawrence Livermore National Laboratory when a fusion reaction generated slightly more energy than was used to start it, something that had not been done before.

However, fusion reactors still have a long way to go. They would likely need to be able to generate ten times the power input to become a viable energy source, which is probably still many years away. But with massive merger projects on the horizon, like ITER, there’s a lot to watch in this space.

While solar and fusion aim to harness the sun’s energy, other energy technology companies are aiming for an energy source much closer to home: the ocean.

Wave Swell Energy’s synthetic blowhole recently completed a one-year test off the coast of King Island, Australia. Inspired by a natural blowhole, the Uniwave200 directs waves into its central chamber, where air is compressed, spinning turbines and sending power to the grid. Wave Swell Energy is still improving the artificial blowhole and trying to make it more reliable and affordable.

Another company, Eco Wave Power, uses man-made structures embedded in the ocean as the basis for wave power generation. Its buoys sit on the surface, where upward waves propel them, creating fluid pressure in the system, which spins a water engine that turns a generator and sends electricity into the grid via an inverter.

The system is designed to automatically recognize incoming storms so it can lift the floats out of the water until the bad weather has passed, preventing damage. The company has already installed buoys in Gibraltar and the port of Jaffa in Tel Aviv, Israel, and they are working on another installation, in Los Angeles, that is expected to be commissioned this year.

Efforts are also underway to harvest wave energy from underwater. A company called AWS Energy has deployed a massive underwater buoy called the Archimedes Waveswing that lies below the surface, tethered to the ocean floor. As it moves up and down with the waves, the generator converts that motion into electricity.
