Ramp Equipment News: Lead-Acid vs Lithium-ion Batteries

Jerry Crump, Director of Business Development, GSE for Green Cubes, compares the merits of using Lithium-ion batteries to Lead-Acid batteries in electric GSE.

With the emergence of more and more electric Ground Support Equipment (eGSE), there is potential for great savings in Total Cost of Ownership (TCO) versus Internal Combustion engines (ICE) and Lithium-ion (Li-ion) batteries are rapidly replacing Flooded Lead Acid (FLA) as the preferred technology for similar reasons. In comparing Lead-Acid batteries versus Li-ion it is important to understand the hidden infrastructure costs for Lead.

For FLA, maintenance costs need to be accounted for along with battery watering and equalisation cycles that need to be tracked in order to ensure that warranties were complied with. FLA can also emit hydrogen when charging due to heating, so it needs to be charged in a properly ventilated space for safety. On the ramp, this is not usually an issue because there is typically enough air flow to allow for any off-gassing to dissipate; however, this can be an issue in
enclosed spaces, such as baggage rooms or battery rooms for equipment charging. In these areas, costly ventilation systems need to be utilised to ensure that the off-gassing during charging does not cause hydrogen buildups.

Blog Post: Exide Lead Acid Batteries – Making Rube Goldberg Proud

On December 16, 1894, W.W. Gibbs, President of the Electric Storage Battery Company (ESBC) made a stunning announcement. Gibbs, who founded ESBC in 1888, asserted that he had just purchased all the patents and rights necessary to make ESBC the sole supplier of electric storage batteries in the United States. These patents were purchased from the General Electric Company, the Edison company, the Thomson-Houston, the Brush, the Accumulator company, the Consolidated Electric Storage Company and the General Electric Launch Company. Whether or not he actually had a monopoly is beside the point. Over the next hundred years, ESBC continued a relentless series of mergers and acquisitions to remain one of the largest manufacturers and recyclers of lead acid batteries in the world. Known today as Exide Technologies, the company would have you believe that their “closed loop recycling process” (cleverly dubbed Total Battery Management by their marketing department) recovers 99% of lead and is a safe and sustainable form of energy storage and motive power.

If he were alive today, I imagine Rube Goldberg would find Exide ripe for satire. Goldberg, who was five years old when W.W. Gibbs started ESBC, was an American cartoonist best known for depicting gadgets that performed simple tasks in overly complicated ways. For instance, in his classic 1931 comic entitled Professor Butts and the Self-Operating Napkin, Goldberg shows a gentleman eating soup with an outlandish contraption strapped to his head and arms. When he lifts the spoon to his mouth, a string tied to his elbow jerks a ladle which flings a cracker past a toucan perched above the professor’s head. When the toucan jumps for the cracker, seeds are dumped into a pail, pulling a cord which ignites a lighter, setting off a rocket attached to a sickle, which cuts a string allowing a pendulum to swing back and forth thus wiping the professor’s chin. Rube Goldberg’s machines skewered our proclivity for the blind use of technology. Why do we expend such vast resources and cause such great damage in exchange for such paltry returns? 

Why indeed?

Lead is a heavy metal, and exposure to even small amounts of it poses significant health risks. Lead poisoning is irreversible and there is no cure. Children are most susceptible, and even low levels of exposure can cause reduced IQs, learning disabilities and developmental problems. High levels of exposure can cause mental retardation, comas, convulsions, and death. Once we became aware of the real and serious hazards of lead, we took concrete steps to remove it from our surroundings. Since 1977, lead has been banned in paint used in all residential and public properties. We’ve also reduced or removed lead from gasoline, electronics, and construction materials. But one very significant source of lead remains: lead acid batteries. According to the World Health Organization (WHO), today around 85% of the world’s lead consumption is for the production of lead acid batteries. 

The fact is, lead acid battery power is neither safe nor sustainable, and when you begin to look at how complicated and dangerous the Total Battery Management system really is, the Rube Goldberg Machine begins to build itself. Even taken at face value – that 99% of lead is recovered in the recycling process – you’re still left with 1%. And after all, how bad could 1% really be? Just ask the residents of Vernon California.

A suburb of Los Angeles, Vernon was home to one of Exide’s lead acid battery recycling centers. Built in 1922, Exide took over operations in 2000. When it was operating, the lead acid smelter at the facility processed an average of 120,000 tons of lead – or approximately 11 million batteries – each year. Residents around the facility complained about the industrial pollution and the negative health impacts it had on the community. Over its last two decades of operation, regulators issued nearly 90 hazardous waste violations and sought to close the facility down, but Exide prevailed in the courts and continued to operate. 

In 2013, Exide was forced to close the facility after admitting to illegally storing, disposing, and transporting hazardous waste for more than two decades. The California standard for lead in residential soil is 80 parts per million. Soil with lead above 1000 parts per million is considered hazardous waste. In 2008 lead levels in the soil around Exide were found to be 50 times the hazardous waste limit. In 2015, California’s Department of Toxic Substance Control announced that as many as 10,000 residential properties and as many as 100,000 residents may be have been affected. Now in the midst of the largest cleanup of its kind in California history, officials estimate costs could be in the hundreds of millions of dollars.

In 2020, Exide and four of its subsidiaries filed for Chapter 11 bankruptcy protection and sold substantially all its operating assets. Later that same year, a federal bankruptcy court allowed Exide to divest itself of responsibilities for multiple waste sites including Exide’s battery recycling plant in Vernon, CA. So far, Exide has avoided paying for any of the healthcare costs associated with their activities, and as long as they comply with the Federal agreement, they avoid criminal charges. But the residents of Vernon, as well as their lawyers, have not given up the fight to recover the damages Exide has caused to them, and their children, and their children’s children.

I imagine Mr. Goldberg would find great irony in a “Total Battery Management” system that was so outlandishly complicated and dangerous and provided such little value. Instead of toucans and rockets, he might depict battery change rooms and watering stations. Leaking acid might eat through strings and toxic fumes might turn large fans. Spent batteries might be flung into a smelter and “recycled” in order to perpetuate the machine, but the air, water, and soil would be damaged beyond repair. Maybe he could find humor in this “closed loop recycling system” whose very existence is predicated not on providing stored energy but rather in maintaining the status quo of a would-be monopoly hanging on to an outdated technology. And then perhaps Mr. Goldberg would be able to do what so many scientific studies, white papers, and peer-reviewed journals have failed to do: convince society that the time for lead acid batteries has passed. After all, how long will we continue to eat soup with toucans strapped to our heads before we realize there’s an easier way to wipe our chins?

Battcon ’21 Attendees Impressed with Green Cube’s (formerly branded as UNIPOWER) Guardian and Aspiro DC Power Systems

At this year’s Battcon conference, we were pleased to present our highly trusted and reliable Guardian and Aspiro DC power families. Conversations were a plenty about the reliability and technology of power systems and how lithium-ion batteries are becoming favored for utility and telecom applications compared to lead-acid batteries. Lithium-ion chemistry has a distinct advantage over lead-acid as it offers batteries with higher energy densities and longer lifetimes that are smaller and significantly lighter in weight.

Our Guardian and Aspiro product lines can operate with a variety of battery chemistries — including lithium-ion, like the new Guardian Lithium batteries from Green Cubes — to provide clean, reliable, safe DC power when AC grid power is lost. Each Guardian battery contains an integrated Battery Management System (BMS), charging electronics, and proprietary Energy Balancing Technology (EBT) that enables active current control, load sharing and State of Charge balancing across connected units. This is a significant advantage for users as lead-acid battery monitoring systems typically must be purchased from a third party and integrated into their battery installation.

All Guardian batteries have active thermal management and feature Lithium Nickel Manganese Cobalt (NMC) or Lithium Iron Phosphate (LFP) chemistries to accommodate multiple utility and telecom applications. Having the BMS built into the batteries allows considerable cost saving for operators. Also, with increasingly strict requirements from the North American Electric Reliability Corporation (NERC), the integrated battery monitoring system can reduce battery maintenance and testing that technicians have to perform, lowering labor and maintenance costs. In addition, Green Cube’s GCC controller with PowCom™ software provides immediate access to performance and alarm information. This provides the operator with a single point where they can access and control their DC power plant remotely from anywhere and monitor the rectification and energy storage performance.

Battcon was a great validation of our high-efficiency DC power systems with lithium batteries that provide the highest efficiency level with a wide operating temperature and input voltage range for mission-critical applications.

Modern Material Handling: Lift Truck Tips, Transitioning to Lithium for Cold Storage

All those frozen foods, subscription meal kits, and refrigerated foods and beverages that U.S. consumers increasingly buy, along with pharmaceuticals that need to be kept cold, equate to a need for more cold storage warehousing. Analyst firm Grandview Research pegs the cold storage warehousing sector to expand at a compound annual growth rate of 13.5% from 2021 through 2028.

Some cold storage DCs may opt for automated storage and retrieval systems or other automation to minimize the need for lift trucks. But for many cold storage DCs, electric lift trucks are relied upon to handle goods.

Cold storage is a challenging environment because of the way the cold negatively impacts the normal capacity of a conventional lead acid battery and issues related to condensation when trucks move between cold storage and ambient parts of the facility for battery swaps and charging.

Airport Industry Review: Li-Ion Batteries Offer Safe, Efficient, Green Power for eGSEs

Jerry Crump, director of GSE business development at Green Cubes Technology, highlights the benefits of lithium-ion batteries for ground support equipment in airports.

Though electric ground support equipment (eGSE) is not a new technology on our airport ramps, it is constantly evolving and is not without challenges – particularly when it comes to implementing the energy needed for eGSE to effectively support airport operations.

Airlines, ground handling companies, and fixed-base operators can utilise new lithium-ion technologies, such as lithium iron phosphate, maximising the available power from their charging infrastructure to keep up with airline and airfield operations and the high power demand curve of certain eGSE’s – like cargo loaders and pushbacks.
