Long-duration intermittent energy storage is a new technology that could save the planet but almost no one knows this technology exists. There are still governments that believe that both solar and wind energy are still too intermittent to become the pillar of the energy system, which is why they affirm that oil and gas are still needed for the coming decades. We share with you our podcast episode about the article audioplayer 00:00 00:00 use the up/down arrow keys to increase or decrease the volume. Something politicians don't seem to know is that wind and solar energy can be stored to generate reliable 24-hour charging. This type of technology already exists and its great advantage is its lower cost compared to fossil fuels. These are not general use batteries , these batteries are not capable of storing electrical energy for a sufficient time and those that do are not available at an affordable price. There is currently no name to describe these emerging technologies we are talking about, but for the purposes of this article we will refer to them as "Long duration intermittent energy storage.
These energy storage systems are flexible and modular and can be built anywhere and can be of any size so they can be used for a variety of purposes including delivering electricity from solar and wind energy 24 hours a day, as well as network balancing and reducing the need for costly network upgrades. The two main technologies that represent long-duration intermittent energy storage are thermal energy storage and liquid air storage, as the name suggests allows the storage of electricity as heat in volcanic rocks or molten storage salt and as cryogenically frozen air. . English company highview power Email Marketing List has already commercialized its own system, called cryobattery , which uses a liquid air system, after 14 years of privately funded research. Another company that is at the forefront is siemens gamesa renewable energy , a famous manufacturer of wind turbines, who has begun the construction of a commercial pilot plant with this new technology, seeking to store electrical energy in hot rock and hoping to be able to offer the results of this new plant in 2021.
These new technologies are based on well-known and established processes and are financed by large companies. The challenge of this technology is not in creating new systems, but in integrating them into current systems and making them profitable. Now let's talk about money. Nothing happens in the world that people are not willing to pay for. It is true that solar and wind energy are less expensive than other energy sources and as time goes by that cost will continue to decrease and long duration intermittent energy storage technology is less expensive than anyone would imagine, despite that these technologies have not yet been fully established. The cost of highview's system, called levelized cost of storage, over the 30-year life of a plant, is close to $100 per mwh today, and its ceo javier cavada claims this cost should fall to $50/mwh ten years from now. By comparison, a new pumped hydro plant would cost $152-198 per mwh, with a comparable lithium-ion battery system costing $285-581/mwh. And with a new gas-peaker plant having a levelized cost of power of $156-210/mwh, and wind power at $30-60/mwh, it may be cheaper to balance the grid with liquid wind.
