Energy storage allows renewable energy to be saved for later consumption, mitigating peak electricity demands and price spikes and creating greater efficiencies within the electric grid while decreasing fossil fuel use.
Energy storage technologies range in size and duration from capacitors capable of holding 1 Wh for only seconds all the way up to grid-scale compressed air, pumped hydro and chemical storage solutions.
Resiliency
Energy storage allows us to save electricity for later use and creates efficiencies and capabilities that can be deployed across multiple segments of the electric grid: transmission network, distribution system and generation source. Energy storage can also be combined with renewable sources (especially wind and solar) to meet peak energy demand without necessitating additional polluting peak power plants.
Resilience in physics refers to an elastic material’s ability to withstand a shock before rebounding back to shape, while in human terms psychologists have studied how people become resilient against life’s challenges. One such strategy that may help is optimism: studies have shown how optimism helps counter the adverse effects of stress by helping individuals access cognitive resources and identify alternative paths forward.
Security
Energy storage plays a pivotal role in increasing energy security by mitigating renewable intermittency, improving grid stability, and supporting energy independence. However, energy storage also requires specific cybersecurity safeguards to protect itself against cyberattacks.
Battery energy storage is the most popular form of energy storage today. Electricity is stored by altering chemical bonds within material to store electricity temporarily before regenerating later – this type of storage includes lithium-ion, lead acid, sodium-based and vanadium-redox flow batteries as the most popular examples.
These technologies are becoming more prevalent, providing access to clean energy sources for remote communities without access to fossil fuels. To reap maximum benefits of these technologies, asset owners and technology providers must establish clear cybersecurity responsibilities through service level agreements and regulatory frameworks; in addition, adherence to industry standards like NERC CIP can ensure robust cybersecurity protections are in place, which will prevent attacks against assets directly as well as address any supply chain vulnerabilities that arise from these assets.
Efficiency
Energy storage provides an effective and rapid solution to fluctuations in electricity demand, helping stabilize the grid and reducing the need for backup power plants.
Energy storage comes in many forms, from rechargeable batteries that store chemical energy directly convertable to electricity for mobile phones to hydroelectric dams that store gravitational potential energy in reservoirs and ice storage tanks used to meet peak daytime cooling demand. Fossil fuels like coal and gasoline also store ancient solar energy absorbed by living organisms which died, were buried, and later turned into fossil fuels like coal or gasoline over time.
All energy storage systems lose some energy during their charging and discharging processes, and increasing round-trip efficiency (the percentage of energy retrieved after full charging) is critical to minimizing losses and optimizing energy storage for the grid.
Climate Change
Energy storage facilitates greater use of renewable energy, helping to reduce fossil fuel dependence, lower carbon emissions and enhance air quality. It can also assist during power demand spikes by storing energy for release when necessary.
Battery storage systems are currently the most widely-used energy storage method; however, other forms of energy storage exist as well. Pumped hydroelectricity utilizes excess power to pump water uphill before releasing it through an uphill turbine to generate electricity; compressed air technology stores energy as cheap heat in rocks or salts for later release into electricity generation; among many others.
Energy storage has become an essential component of our mission towards sustainability. Communities and leaders who support projects that incorporate battery storage are helping make an impactful statement about its importance as we transition towards clean power sources that balance supply with demand. Such initiatives also create jobs while stimulating economic development by demonstrating its worth as part of greening the planet. Everyone benefits when leaders take decisive action on climate change with energy storage at its center.
