Energy Storage Tariffs
“How can you be paid for your energy storage?”
Energy storage is one of the most crucial technologies for the energy transition. And like solar before it, it will need some help from policy to get its feet on the ground. One of the things it can use are feed-in tariffs, so that any energy sent to the grid will be compensated financially. These Energy Storage Tariffs are being discussed by multiple energy market operators around the world.

Energy Storage Mandates
“How can governments use policy to increase the amount of storage on the grid?”
`Energy storage is one of the hottest things in the energy world right now. But despite its seemingly invincible potential, it still needs government action to come online. One clever way to do this is to make a policy stipulating that utilities need to adopt a certain amount of energy storage through an Energy Storage Mandate. This is commonly implemented in California and other governments to meet their carbon neutrality goals.

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.
