LIQUID AIR ENERGY STORAGE, THE CLEANEST AND MOST ECONOMICAL ROUTE TO A 100% RENEWABLE REALITY

To replace fossil fuel electricity generation, we must ensure that renewable energy, which is intermittent and variable, can be stored and used in times of overproduction to power times of peak demand. Due to intermittency, wind and solar naturally do not create a lot of inertia. Maintaining stability becomes a very serious challenge for grid operators to avoid grid chaos which can cause high peak demand prices, power outages, and even blackouts for electricity users.

Highview Power has developed the liquid air energy storage (LAES) to overcome the limitations offered by other well-known technologies: pumped hydroelectric and batteries. Hydro requires many years of development and construction, and usually raises a host of environmental issues once the right location has been found. Batteries can store small quantities of energy and their large-scale use is costly, not to mention their short service life and the degradation they suffer from continued usage.

During those years of development, LAES technology was demonstrated by two pilot projects in England, capable of storing large quantities of energy for months in any location, at a much cheaper price than any other energy storage system. Highview’s technology is highly modular, meaning that a project’s power (MW) and storage capacity (MWh) can be easily scaled by simply adding larger turbines or adding tanks, with no technical limit beyond the economic requirement of each project. For example, by increasing the power of the air-driven turbine, one of the most expensive system components, fourfold from 50 MW to 200 MW, its cost is approximately double, an advantage due to economies of scale. In short, the larger the project, the lower the cost per kW, and logically, the more storage hours, the lower the cost per kWh.
