The Path to Drawdown: Energy Storage

On the path to electrify everything, the world needs more renewable sources of energy. But also needed are energy storage systems and batteries. Because the two dominant sources of renewable energy - solar and wind - are intermittent (they only generate electricity when the sun is shining or the wind is blowing), their supplies often don’t match their demand. 

The conventional way of supplying power when the demand for electricity peaks is for utility companies to fire up “peaker” plants. But most peakers run on natural gas and are highly polluting.

A wider adoption of utility-scale and distributed energy storage systems and batteries is the answer. Utility-scale energy storage is the use of technologies and practices to store energy on a large scale, often managed by utility, industrial and power companies. Distributed storage systems are smaller in scale and use standalone batteries and electric vehicles (EVs) to store energy. Distributed systems are usually managed at the level of residential and commercial buildings.

Neither of these solutions directly help cut greenhouse gas emissions, but they both facilitate the development of more renewable energy sources and ultimately smooth the transition in the energy system. 

While Project Drawdown doesn’t model the growth of energy storage so as to avoid double-counting with renewable energy solutions, it’s clear that their production and adoption need to accelerate, and their cost needs to fall to accelerate the shift to a zero-emission grid.


CBAK Energy Technology, Inc., together with its subsidiaries, develops, manufactures, and sells lithium batteries in Mainland China, the United States, Israel, and beyond. Their products are used in applications like electric cars, electric buses, e-bikes and e-scooters, sight-seeing cars, energy storage, uninterruptible power supply, and other high power applications, as well as cordless power tools. Formerly known as China BAK Battery, Inc., CBAK Energy is based in Dalian, China.

CBAT's Role in Drawdown

CBAT provides lithium-ion battery packs that can be used in light EVs, standard EVs, electric tools, energy storage such as uninterruptible power supply and other high-power applications.  These lithium-ion battery sales accounted for 60% of CBAT’s 2020 revenue.

They’re also in the midst of trial production of a special lithium battery that’s designed to be used in ultra-low temperatures settings. Applications of this battery includes high-latitude and high-altitude energy storage, base stations, transportation, unmanned drones, aviation and aerospace areas. 

CBAT is expanding their production rapidly as demand for lithium-ion batteries rises in China. They’re constructing a new production line with an annual capacity of 400 KWh to produce an additional 100,000 units of their batteries per day. 

CBAT also entered into a framework investment agreement to begin developing lithium battery projects with a total production capacity of 8 GWh per year by the end of 2023.

CBAT: What We Like

We’ll update this section one CBAT makes sustainability information available.

CBAT: What We Want to See Improve

Shift Away from Dirty Banks

CBAT has relied on a couple of banks for financing in the last several years. But unfortunately these banks happen to be some of China’s top funders of fossil fuels. Agricultural Bank of China and China Everbright Bank’s investments in tar sands, oil and gas have increased in recent years, and they show no signs of winding these investments down. We urge CBAT to stop enabling these banks and their fossil fuel clients, and instead switch to financial institutions that, as a matter of principle, don’t fund high-emitting sectors. 

Disclose Sustainability Metrics

We know very little about CBAT’s carbon footprint or the carbon footprint throughout CBAT’s supply chain. Although all of CBAT’s suppliers are based in China, the planned expansion of their production capacity leads us to think that the company’s and their supply chain’s emissions may grow in the coming years. To hold them accountable, they need to disclose key sustainability metrics like direct and indirect GHG emissions and the sources of their energy consumption.

Stay Away from the Military

We’re excited about the new lithium batteries that CBAT is developing that can operate in low temperatures. But because the potential applications for these batteries include unmanned drones and aviation, we want CBAT to steer clear of selling these new batteries to militaries or defense contractors. Instead, we urge them to focus on contributing to the wider adoption of EVs and energy storage systems.
