Suggested Answer Key Good morning! I’m Aidar Yerner and I work for Kazakh Energy Storage Solutions Ltd. For years I had been evaluating the effectiveness of different energy storage solutions, so when I heard about this amazing idea, I was excited to finally bring it to Kazakhstan. Every year in Kazakhstan we are increasing the amount of energy we are producing and storing, but what about if, rather than using batteries, we tried something a little different? This alternative solution is called an energy storage tower. The revolutionary energy storage solution is based on simple physics. The tower requires a crane that is 120 metres tall and has six arms as well as a set of huge concrete blocks that weigh 35 tons each. As the demand for electricity decreases, the crane uses the surplus energy to build a tower from the blocks. Then, when the demand increases again, the crane lowers the blocks it had used to build the tower. Gravitational potential energy is then harnessed and converted into electricity. So, why are energy storage towers a great solution for Kazakhstan? Well, they are efficient – they store enough energy to power 2,000 homes for a day. They are also cheap because the blocks can be made from waste materials, and these blocks are durable - they last between 30 and 40 years. In addition, no chemicals are required for this method of storage, so it’s environmentally-friendly. Do you think these towers are a viable solution for our future? I’d be interested to hear your thoughts after the Q&A session. Thank you for listening. |
