With 60% of global greenhouse gas emissions coming from energy, there''s a universal need to make our power system as clean and cost-effective as possible. Renewable energy sources like solar and wind are excellent options, but they''re intermitten by nature, meaning they''re effective only when the sun is shining and the wind blowing.
When asked to define grid-scale energy storage, it''s important to start by explaining what "grid-scale" means. Grid-scale generally indicates the size and capacity of energy storage and generation facilities, as well as how the battery is used. The size of a battery storage facility is its standard physical dimensions, and the capacity is the amount of electricity the facility can put out and store, measured in kilowatt hours (kWh), megawatt hours (MWh), gigawatt hours (GWh), and at some point in the future terawatt hours (TWh).
Grid-scale is different in terms of battery size and use cases than residential scale or commercial and industrial sale. Here is a breakdown of the differences between the three main levels of energy storage systems:
Today''s systems using lithium-ion batteries are different from those pumped hydro, compressed air, or gravity because they are fast, providing power almost instantly when needed. They are also scalable if there''s a need for expansion. Batteries are also portable, unlike other storage systems that need to be on mountaintops or in underground tunnels.
Grid-scale batteries have a round-trip efficiency (RTE) measurement, which shows the energy lost during storage and retrieval, usually 70–90%. Lithium-ion batteries reach an industry-high RTE of 90%+, lead-acid measures about 70%, flow batteries are around 50–75%, and metal-air designs can be as low as 40%. A crucial component to the cost-effectiveness of a battery is mitigating the energy wasted during charge and discharge.
The lifespan of a grid-scale battery depends on its chemistry, how long the battery has been used, and how often it''s charged and discharged. Applications of lithium-ion batteries in grid-scale energy storage systems last about 10–15 years. Lead-acid is between 5–10 years. Another factor is where the batteries are stored, as batteries kept in higher or very low temperatures can experience a shorter lifespan.
Energy systems that use grid-scale battery storage are more reliable, efficient, and environmentally friendly. A top benefit is the ability to stabilize the grid during fluctuations from renewable sources. They store energy during low demand, like the sunny afternoon or a windy night, and then release that energy during peak demand times. A grid-scale battery also regulates frequency by responding quickly to changes in generation and demand, which leads to cost savings.
Another advantage is blending renewable energy sources into the grid. Weather can be unpredictable and therefore so is the power generated by it. A grid-scale battery stores energy when there''s no wind and the sun isn''t out. Batteries maximize the use of renewable energy and help move away from fossil fuels.
Grid-scale batteries can also provide a crucial backup system during outages or emergencies. They provide power to essential services like communication networks, hospitals, and emergency services, making sure they are always operational. Grid-scale battery storage balances supply and demand, improves dependability, lowers costs, and ultimately offers a sustainable energy solution.
Startups are leading the charge with non-lithium battery chemistries to overcome the barriers above and promise a safer, more affordable, greener future. Many integrators are "chemistry agnostic," meaning they''re prepared for the next wave of battery technologies.
Alsym Energy has developed a cost-effective, high-performance, rechargeable battery technology that doesn''t use cobalt or lithium. It leverages readily available materials that are non-flammable and non-toxic. Alternative battery chemistries like Alsym''s are designed with affordability in mind to ensure everyone has access to clean energy.
There''s an urgent need for low-cost, clean energy solutions to reach net-zero greenhouse gas emissions by 2050 and mitigate the far-reaching impacts of climate change. The intermittent nature of renewable energy sources requires a backup plan. Grid-scale energy storage is vital for the future of renewable energy and to meet the changing demands of the grid. Alsym''s innovators are on the case by working to develop a novel battery technology for a sustainable tomorrow.
