Ultracapacitors for EVs
“What is one possible way to speed up EV recharge times?”
In order to achieve deep-decarbonization of transportation, the global vehicle fleet needs to become much more electrified. However, the long recharge times associated with electric vehicles are a roadblock for this to happen. One way to solve this would be to implement Ultracapacitors for EVs. Ultracapacitors have quick recharge times, low weight, and low degradation, making them a formidable option. The downside is that manny ultracapacitors lack the storage capacity found in traditional solid-state batteries. But if this problem gets solved, then expect a paradigm shift in the EV industry!

“How can we store energy using steam?”
With the advent of the new energy paradigm, energy storage will play a bigger and bigger factor. Although batteries are promising, they are not an all-encompassing technology and will need support from other systems.
One simple method for storing energy involves steam. What if we were to have a container half filled with cold water and connected to a boiler. Steam can be blown if from the boiler into the container, which condenses and warms the water. When the water is about ¾ of the height, it will be considered stable. A valve can then be opened to release energy by driving the steam through a turbine and boiling the water from the resulting pressure drop. This system is known as a Steam Accumulator and is being constructed in conjunction with many solar thermal plants.
Distributed Energy Storage
“How can we best optimize energy storage?”
If you ask a renewable energy expert what is one of the biggest hurdles facing the proliferation of solar and wind, chances are you’ll hear energy storage. Storing energy requires a massive infrastructure investment, whether it be in batteries or other mechanisms. However, for the most optimum approach, all methods should be combined to create a Distributed Energy Storage solution. This way the maximum amount of energy can be stored for later use.
