The Role of Energy Storage

Batteries and energy storage solutions have been a vital part of ensuring safe, affordable and reliable energy worldwide for well over a century. Batteries are now ubiquitous in modern-day life, from providing the initial energy required to start internal combustion engine (ICE) vehicles to powering passenger and industrial electric vehicles (EVs) to providing critical backup power for the electricity grid, telecommunications, disaster relief and healthcare facilities.

Stationary batteries can be deployed at critical locations and provide utilities with the adaptability they need to meet the world’s growing power demands and provide reliable electricity whenever it is needed, wherever it is needed. When excess electricity is produced – for instance, by wind turbines at night – batteries store that green electricity to be used at a later time. Energy storage solutions eliminate the need to curtail renewable electricity generation where there is insufficient demand and reduce the amount of variability on the power grid. As countries, companies and communities set climate targets to increase their renewable energy usage, batteries will bridge that gap between strained electricity grids and meeting their goals.

Automotive batteries for electric transportation and motive power batteries for industrial electric vehicles also support emission reductions. Batteries are dramatically changing the transport sector as pressure to transition from ICE vehicles to hybrids and EVs increases. Energy storage solutions support decarbonization goals in transportation and industrial sectors by eliminating the emissions produced by combustion engines, especially if the batteries are charged by renewable electric sources. Stationary batteries can also expand the availability of EV charging, especially in rural areas where the infrastructure doesn’t currently exist.

“Batteries are sustainability technology. While there are different types of battery/chemistries, they all support critical applications across the globe. EnerSys is committed to developing innovative, reliable and cost-effective energy storage and service solutions that support the needs of current and future customers.”

LEAD BATTERIES

Lead battery technology is tried and true and has been around for over a century. Lead batteries are particularly advantageous for short bursts of electricity required to cold crank engines. Unlike other technologies, lead batteries are rated for high altitude. Their weight provides ballast when needed, and they are also often the most cost-effective compared to other energy storage technologies. Most impressively, lead batteries have a well-established, closed-loop recycling economy that spans the globe. EnerSys® is a leader in this space – for more information about our role in lead recycling, please visit the End of Use Management section of this report.

LITHIUM-ION BATTERIES

Lithium-ion Batteries (LiBs) are a relatively new technology, first introduced into the market in the 1990s. There are different types of LiBs, including Lithium Iron Phosphate (LIP), Lithium Cobalt Oxide (LCO), Lithium Manganese Oxide (LMO) and Lithium Nickel Manganese Cobalt Oxide (NMC). Each battery type has specific energy, life cycle and application advantages. Lithium chemistry technologies are now the dominant battery system for portable applications, especially electric vehicles (EVs). LiBs have a higher energy density than most other chemistries, including lead-acid batteries, meaning that they can store more energy compared to other batteries of the same size. They are also lighter in weight than lead batteries with the same capacity, making them ideal for EVs. Additionally, lithium batteries can be cycled more often and more deeply on a given charge, enabling longer use before a recharge and a greater overall lifespan. However, LiB technology faces challenges, including responsible end-of-use processes, as they do not yet have the same circular life cycle infrastructure as lead batteries. EnerSys is working diligently, along with industry groups and other affected companies, to support the development of this infrastructure.

Motive Power

EnerSys is the world’s largest manufacturer of industrial forklift batteries and chargers.

The EnerSys line of Motive Power batteries is extensive, with innovative products spanning a variety of battery chemistries for every budget application. Our batteries are used primarily in electric forklift trucks and other commercial electric vehicles. EnerSys is the world’s largest manufacturer of industrial forklift batteries and chargers.

Almost 65% of the forklifts manufactured today are powered by batteries. From Flooded Lead Acid (FLA) batteries to virtually maintenance-free Thin Plate Pure Lead (TPPL) and now Lithium-ion batteries as well, EnerSys can supply solutions for the unique needs of our customers. Our world-class Ensite software allows current and potential customers to make confident, data-driven decisions regarding what power solution is best for their fleet. This software compares multiple battery chemistries and identifies the lowest Total Cost of Ownership (TCO) solution tailored to their application. Our premier data reporting systems also record and analyze vital data during operation to make sure operators are meeting their productivity and profitability goals.

Powering forklifts and other industrial vehicles electrically with batteries has numerous advantages over traditional fossil fuel sources. They emit no greenhouse gas (GHG) emissions at the vehicles, and the emissions from the electricity used to power them are significantly less than from propane or even hydrogen-powered forklifts based on the average U.S. power grid makeup. If the forklifts are charged by renewable energy sources, then the reduction in GHG emissions is even more significant. This is a lower carbon option for our customers to power their material handling needs, supporting their sustainability efforts and goals.

The benefits of our products go beyond just greenhouse gas emissions and energy. Our next-generation TPPL batteries reduce our customers’ water use as well, displacing as much as 50 liters of distilled water per week. This saves our customers time, water costs and often energy costs for water distillation. TPPL also provides charging efficiencies, with full fast charging in less than two hours. This allows our customers to reduce their electricity usage, maintenance and energy costs and ultimately lower their emissions.

Finally, in addition to improving our customers’ environmental performance, EnerSys Motive power batteries can also save money by offering reduced operating and maintenance costs compared to traditional forklift fuel sources. ICE vehicles require regular maintenance to keep their engines and mechanical parts working over the vehicle’s lifetime – our batteries, especially LiBs and TPPL batteries, eliminate the need for that. This can significantly reduce an operator’s maintenance capital budget, which allows them to focus their money on their operations and sustainability programs.

“EnerSys is a sustainability technology company with a clear place in the clean energy future. Our batteries have been changing the landscape of Motive Power for decades, making material handling greener and more cost-effective for our customers. As companies continue to set goals to reduce the greenhouse gas emissions and energy usage for mobility in their operations, our products and services will continue to provide the solutions to keep them moving forward.”
