Great Renewable Energy Storage: Compressed Air

by: Sharai Hoekema

It comes as no surprise that fossil fuel-generated electricity is on the way out. It is not just highly polluting and a great contributor to global warming, it is also unsustainable in and of itself. Its limited availability is only a minor problem, it seems.

Renewable Energy Is Not Limitless

Renewable energy, including electricity generated by the rays of the sun or by the wind, is the way of the future. Not only is it much better for the environment, but it is also cheaper - coming in at a significantly lower price than its carbon-rich friend. Unfortunately, there is one major issue that is currently preventing it from taking over the market and becoming everyone’s go-to energy source.

While in theory, renewable energy is fully renewable, as the sun will keep on shining, and the wind will keep on blowing, it is not always available. The sun goes down at night, and we might not be able to catch its rays on rainy days. Similarly, the wind might sometimes stop blowing, rendering a windmill useless for shorter or longer periods.

Storing Electricity Using Compressed Air

The solution to this problem could be reasonably straightforward: coming up with a way to effectively store energy at a reasonable price. We are already doing so, most notably through batteries. So we should not have to re-invent the wheel. Not entirely, at least - because there is a solution that is underdeveloped but extremely promising. Compressed air.

Useful for blowing up balloons and air mattresses. But also for storing energy. Cheap, and not too complicated. You just suck in air from the atmosphere, compress it, and store it as pressurized air. As soon as you need energy, you can let out this air and run it through a machine that separates the energy, setting in motion an electrical generator.

The air can be stored in steel tanks, which is the more expensive solution, or in underwater containments or underground caverns. These spaces could be vast, while compressed air does not take up a whole lot of space. Thus, vast quantities of electricity could potentially be stored at a low cost. Unfortunately, the idea has not gotten much traction with those in charge.

Three Reasons Compressed Air Storage Is Not Taking Off Yet

  • First, the technology in question is not as straightforward as blowing up a balloon. It is not as simple as letting in air, keeping it inside and letting it out again when needed. It requires a wealth of different technologies, including those required for compression, expansion, heat exchange, storage, and extraction. All of those need to work together correctly if it is to work. This makes it somewhat complicated.
  • Second, this storage is mostly useful for the long term. This means that it currently falls in a space in the market that is relatively limited. After all, renewable energy is either used instantly or stored for a really short amount of time, using batteries. For longer-term use, at night, or in the wintertime, we still turn to fossil fuel-generated electricity as a backup. To start using compressed air storage for renewables, a change in mindset will need to take hold of the market. Plus, the procurement of some rather expensive technologies and equipment.
  • Third, the investment is not just pretty significant; it is also steady - in the sense that it lasts a lifetime. A private investment usually requires a high rate of return, preferably in the short run. Thus, investors are not as keen on the value left in the long term. Yet compressed air technology is designed to last and operate a lifetime, if not more. The underground caverns, for instance, could easily be used for 100+ years. Machines that are designed to compress and expand the air will be good for at least 50.

Renewable Energy Storage: Looking At The Bigger Picture

As always, it looks as if money rules the electricity industry. People are more concerned with short term profits, as they often are. Perhaps this is the cue for governments to step in and take on the investments. No one else seems willing to do so thus far.

The prospect of storing renewable energy using advanced techniques such as compressed air might be useful. Still, while there will be more easy and more profitable solutions - such as fossil fuel -,, it will remain a hard sell.

Compressed air is also able to power vehicles that cost considerably less than those powered by toxic batteries. Pneubike is developing an open source compressed gas motor that can be used to create an environmentally sustainable infrastructure. Pneubike.com
