Panasonic's Battery Factory: The Coal Controversy Explained
Written on
Overview of Panasonic’s Battery Endeavors
Panasonic stands as a pivotal player in the electric vehicle (EV) industry. The company played a crucial role in the early production of Tesla vehicles, which utilized its battery cells. To maintain its competitive edge amidst increasing demand and intensifying competition from China, Panasonic is expanding its production capabilities. However, the construction of their new $4 billion battery facility in De Soto, Kansas, has sparked criticism due to its reliance on coal power, leading to concerns regarding the environmental impact of EVs and their batteries. Yet, the reality may not be as bleak as it appears.
The Energy Needs of the New Plant
Why is coal power necessary for this facility? The De Soto plant, once operational, will generate an impressive 30 GWh of battery capacity annually—equivalent to powering 500,000 standard-range Model 3s. To support such operations, Panasonic estimates a continuous power requirement of 200 to 250 MW, comparable to the energy consumption of a mid-sized city. This surge in energy demand has compelled the local utility to retain a coal power plant for the foreseeable future, postponing its transition to cleaner natural gas.

The environmental implications of coal are alarming. It is significantly more polluting than natural gas and vastly more so compared to renewable sources like solar and wind. The reliance on such a detrimental energy source raises valid concerns about the environmental sustainability of the EV sector. Local political figures have pointed to this situation as evidence of the need for a stable energy base, suggesting that renewables alone cannot meet energy demands without supplemental sources like coal or gas.
However, these fears may be overstated and potentially serve as anti-climate action narratives.
EVs vs. Traditional Vehicles
As previously discussed in the article "Are EVs Really Better Than Combustion Cars?", electric vehicles, even when charged predominantly by coal-derived energy, have a lower lifetime carbon footprint than traditional combustion vehicles. The study referenced utilized a Tesla Model 3, whose batteries were produced in a facility that operated with an energy mix that included fossil fuels. Thus, despite the coal dependency of the new plant, the EVs produced there will likely outperform gasoline vehicles in terms of environmental impact.
Exploring Alternative Energy Sources
Interestingly, the plant's energy needs could be met without coal. If Panasonic were to construct its own energy generation facility, assuming an average requirement of 225 MW, the plant would consume approximately 1,971 GWh annually. The establishment of a coal power plant would necessitate an investment of around $1.01 billion, not including fuel costs. Over the expected 20-year lifespan of the factory, the total operational cost for coal energy could reach an astounding $8 billion.
What about nuclear energy? While it offers similar low carbon emissions to renewables, its initial costs are considerably higher. Traditional nuclear plants cost about $9 million per MW, leading to an estimated $2 billion for a facility meeting the plant’s energy needs. When factoring in fuel costs, the total energy expense over 20 years could be around $3.9 billion—still lower than the projected coal costs over time.
The Case for Renewables
Critics of renewables argue that they are insufficient to serve as a primary energy source. However, this claim is misleading. A 1 MW solar array generates about 2,146 MWh annually and costs roughly $750,000 to establish. Consequently, a solar array capable of powering the factory would total around $688.5 million—substantially less than coal or nuclear.
Nonetheless, solar energy is intermittent, necessitating a significant storage solution. A recent analysis indicated that a fully renewable energy grid would require storage equivalent to 7.2% of its annual energy consumption to ensure reliability. This translates to a need for a 141.9 GWh battery for the factory, which would be the largest grid storage battery to date. Tesla's grid storage costs around $333,309 per MWh, leading to an eye-watering $47 billion price tag for this storage alone!
Fortunately, advancements such as Form’s air-breathing batteries—costing just $2,000 per MWh—could dramatically reduce costs to approximately $0.972 billion for the same capacity. Altogether, utilizing solar and innovative battery technology could bring the total energy costs over 20 years down to just $1.66 billion, making it 58% cheaper than nuclear and 80% cheaper than coal.
Conclusions on Energy Transition
While the figures presented here are estimations, they illustrate that Panasonic’s battery plant can be effectively powered by renewables if implemented correctly. The underlying issue lies not with EV manufacturing or battery production but with the sluggish transition of utilities and energy companies to renewable and low-carbon solutions.
This challenge is not unique to Kansas; it is a global issue. Energy companies often favor the lower initial costs of coal and gas plants, which leads to a reliance on these older infrastructures to meet growing energy demands. In contrast, the upfront costs for nuclear and renewables are higher, but their long-term benefits are substantial due to minimal or negligible fuel expenses.
Ultimately, the situation surrounding Panasonic’s new battery factory underscores the urgent need for energy companies to accelerate their adoption of renewable technologies to align with modern energy demands. The technology exists; it simply requires a swifter implementation.
