The Future Of Energy Storage Beyond Lithium Ion


Over the past decade, prices for solar panels and wind farms have reached all-time lows. However, the price for lithium ion batteries, the leading energy storage technology, has remained too high. So researchers are exploring other alternatives, including flow batteries, thermal batteries, and gravity-based systems.

Among the best barriers facing the sustainable energy market is the absence of massive storage. It is widely known that an affordable solution to sustainable energy storage is required in order to adopt the objective of 100 percent usage of renewable resource sources. Lots of possible solutions to the problem of electrical energy storage are being looked into and tested. This article will try and analyze to identify the viability of a few of the most typical theories.

Present storage alternatives for electrical energy

Some conversation is needed about the present techniques and ideas referring to the storage of electrical energies. The subject has been the focus of many research study studies and many theories abound. The following are the five most typical alternatives together with a fast analysis:

1. Electrical energy- Supercapacitors store energy with triggered carbon. They can be almost immediately charged and release stored energy efficiently. Much research study is underway to develop more affordable and readily available materials. Graphene is one possible product. Large-scale storage is not practical at this time. Supercapacitors hold much guarantee in the future, but existing technology and cost make this an expensive technique anytime in the near-term.

2. Possible energy- Hydro-electric pumped storage is the most popular kind of choice right now. Excess electrical energy is used to pump water to an upper reservoir and when needed the water is launched to run turbines to create electricity. This is an excellent intermediate storage system, but on a large-scale basis, the availability and expense of facilities is prohibitive.

3. Mechanical energy- Compressed air and flywheel energy storage hold some guarantee. This type of system uses excess energy to compress air and the air is then kept until required. When the air is launched, it can power turbines to produce electrical power. There are a number of tasks being evaluated and the outcomes are encouraging. These kinds of storage are also expensive and require a big facilities build-out.

4. Electrochemical energy- Battery storage also holds pledge in the future. Large-scale storage is not feasible with present technologies. Unless a significant break-through takes place, battery storage is too cost-prohibitive.

5. Chemical energy- Fuel conversion storage is the most promising choice right now. If this can be achieved economically, this has the best large-scale and long-lasting attributes that are needed for viable energy storage.

This has actually been an extremely short summary of energy storage innovation. Currently, no comprehensive option has actually been provided for resolving our storage problem. In a future post, we will explore a really appealing fuel conversion process, taking place in Germany. Sustainable energy storage is really crucial to the practicality of a total eco-friendly energy future. Excellent minds are at work and confidence is high that a service will be found.
