6 FAQs about [What is the problem with energy storage ]
Why do we need a long-term energy storage solution?
As renewable energy capacity grows, we must identify and expand better ways of storing this energy, to avoid waste and deal with demand spikes. Utility companies and other providers are increasingly focused on developing effective long-term energy storage solutions.
What is energy storage and why is it important?
Energy storage solutions are vital to both areas of research. The main issue with renewable energy is its fleeting nature. When the wind is blowing or the sun is shining, the electricity that is produced must either be used or lost. On the other hand, when it’s cloudy or the wind isn’t blowing, power may not be available to meet demand.
Is energy storage a must?
"If we want to have a significant part of our energy come from renewable sources,storage is a must," says Ali Nourai, manager of energy storage at American Electric Power, a utility company in Columbus, Ohio, and chairman of the Electricity Storage Association, a trade association in Washington DC.
Why is electrical energy so difficult to store?
Ever ephemeral, electrical energy is difficult and expensive to store in large quantities. The lack of good storage options has plagued utility operators for generations.
