EnerG2 manufactures engineered carbon materials for applications in a variety of different electrochemical storage systems. Our team has harnessed the ability to modulate the physical, chemical, and electrochemical properties of high-purity carbon in a full-scale manufacturing environment. The inherent cost and quality of our operations have made EnerG2 carbons the preferred carbon materials for a number of energy storage chemistries.

Physical adjustments to surface area, pore size distribution, and total pore volume can yield carbon material with a broad range of surface properties. We tailor these properties for adaptation to the specific requirements of a given energy storage application. In conjunction with physical changes to the material, our approach allows for optimized processing in our customers’ manufacturing lines. The intrinsic purity of our manufacturing processes and raw material inputs allows for optimal electrochemical stability in a range of electrochemical environments.



Lead acid batteries are the workhorse of the industry and the most ubiquitous form of energy storage in the world. Applications range from automotive starter batteries to batteries for data-center backup power and renewable energy integration. EnerG2's engineered materials offer the precisely tailored pore structures and high purity required to dramatically improve the performance of lead acid batteries.

New Challenges for Lead Acid

In the automotive sector, the start-stop hybrid requires the battery to provide many more cycles at a higher rate of charge and discharge than a traditional lead acid battery can accomplish. Utility-scale renewable storage applications demand a lower cost-per-unit of energy stored over the life of the battery (kWh cycles) than a traditional lead acid battery can achieve. These and other applications have forced the manufacturers of lead acid batteries to seek new solutions for new problems and to fundamentally re-engineer these batteries.

The EnerG2 Advantage

Innovative materials are opening new performance horizons for lead acid batteries. EnerG2 carbons offer the precisely tailored pore structures and high purity required to provide the power, charge acceptance and cycle life improvements that enable lead acid batteries to meet the demands of new high-performance applications. Such applications include forklifts, golf carts, e-bikes, grid-level energy storage and key enabling start-stop technologies in hybrid-electric vehicles.

Ultracapacitors fully charge and discharge in seconds while enjoying a life of up to a million or more charge and discharge cycles. Ultracapacitors (also known as electronic double layer capacitors (EDLCs) or supercapacitors), are energy storage devices for high power and high cycling applications. Unlike batteries, which use a chemical reaction to store energy, ultracapacitors use a static charge stored in carbon-based electrodes.

Inside the Ultracapacitor

The ultracapacitor is a relatively simple device, consisting of two symmetric carbon electrodes attached to metallic current collectors, separated by a separator material. Ultracapacitors store electric charge by separating positive and negative charges on the massive surface areas created by porous carbon electrodes. Electrolyte ions are attracted to the surface area of the carbon electrode; the more surface area, the greater the charge stored. In addition, larger channels in the carbon allow rapid release of the ions to improve the power performance of the device.

The EnerG2 Advantage

EnerG2 manufactures ultracapacitor electrode carbons with the highest energy- and power-density available in the world. These carbons offer unprecedented value through significant increases in ultracapacitor energy density while reducing the total device cost per unit of energy stored to the lowest $/Wh and $/kW in devices of any carbon available. EnerG2 offers customers unmatched material purity to improve stability and to enable higher operating voltages. The voltage improvements will double energy and power densities in devices over the next 2-3 years. In addition, EnerG2’s unique carbon structure delivers best-in-class power performance.

Absorbed Natural Gas


EnerG2 has leveraged its polymer chemistry technologies to develop materials for adsorbed natural gas (ANG) and low pressure compressed natural gas (CNG) applications.

Today's conventional approaches to natural gas storage are compressed natural gas (CNG) and liquid natural gas (LNG), but both have drawbacks - high costs, low storage efficiency and safety concerns. The favored alternative to these two storage methods is adsorbed natural gas (ANG) on a porous medium such as activated carbon. EnerG2 has leveraged its synthetic carbon technology to develop new materials for ANG applications. ANG provides better storage characteristics than high-pressure CNG storage because it is safer and far more efficient than CNG (500 PSI versus 3500 PSI). EnerG2 has developed ultra-high surface area carbon materials that can be applied in natural gas storage systems at pressures substantially below those typically required for current CNG systems and without the liquefaction and boil-off challenges of LNG.

Advanced Battary


A number of advanced battery solutions are currently making their way from the lab to the consumer. With energy densities greatly exceeding that of traditional lithium ion batteries, these chemistries promise to dramatically expand the use and applicability of energy storage. In one important example, lithium air chemistries have a theoretical energy density equivalent to gasoline, making fully electrified transportation a reality. Like lithium batteries in the 1980’s, these technologies hold great promise once technical and cost challenges are overcome. In these chemistries, EnerG2’s advanced engineered carbon materials will help to solve a number of the key technical challenges required to commercialize the technologies.
