The battery industry is currently dominated by lithium-ion batteries. We have them in our phones and computers. They power electric cars. And they are increasingly being used to store energy generated by solar panels and other renewable energy sources.
UPS recently announced a demonstration project that will put a prototype electric truck powered by a hydrogen fuel cell through the delivery company’s challenging paces. Fuel cells have been used in some commercial vehicles to power auxiliary systems, but this is the first time that they will be used to propel a vehicle.
The great majority of solar cells being manufactured today are based on silicon crystals. That technology has come a long way over time and has gotten cheaper and more plentiful as the industry has grown.
Ocean energy is still one of the biggest untapped clean energy sources on the planet. There are many studies that have shown that it could provide power for millions of homes in the U.S. alone. But despite this, the technology is still in its infancy and it is unclear when and if it can become a major contributor to our energy needs.
