WattJoule
Corporation, a developer of next-generation liquid electrical energy
storage systems, has developed and built a new system demonstrating a
major industry cost breakthrough. The new storage platform is called
ElectriStor™ and will be offered to system integrators as the preferred
core component for storing large amounts of solar and wind energy.
One of the major barriers preventing the widespread adoption of
large-scale energy storage has been cost. WattJoule has engineered the
ElectriStor™ platform based on the redox flow battery concept
where electricity is stored in a liquid. WattJoule’s proprietary liquid
electrolyte is mostly water, and the company has developed a new,
inexpensive process to make it in large quantities. Early liquid energy
storage systems have suffered from a number of technical and cost
limitations. Recently there have been several technical breakthroughs to
overcome these constraints. WattJoule has both developed and exclusively
licensed key technologies that, in combination, dramatically lower
energy storage costs to $150 per kilowatt-hour in its first-generation
energy storage product.
WattJoule has completely re-engineered the conventional vanadium-based
storage system in order to dramatically lower cost based on solving
critical limitations. The company has developed an advanced vanadium
liquid that completely eliminates the need for expensive air
conditioning for system cooling, that other systems require for proper
operation. This new liquid stores more energy, in a smaller system with
less material. The energy-conversion components now handle considerably
more power, but use less material. To achieve all this, WattJoule has
also developed a proprietary cell design, electrodes and separator. The
company has a multi-generational pipeline of advanced storage liquids
and materials in development to further reduce long-term cost. From
early durability testing, WattJoule predicts a system lifetime of over
20 years.
“Our ElectriStor™ platform is the culmination of five years of
intensive research, development and engineering work by our world-class
team,” said Greg Cipriano, VP Business Development and Co-Founder of
WattJoule. “We now have a combined technical team, with our strategic
partners, of more than 30 engineers and scientists in multiple
disciplines. The capabilities of our new platform are a direct
reflection of the hard work and dedication of this team to solving a
difficult, almost intractable, set of technical problems.”
“WattJoule’s technology combines high power, high energy, and a wide
operating temperature range in a smaller, less expensive package,” said
Dr. H. Frank Gibbard, CEO and Co-Founder of WattJoule, “we expect it to
be highly competitive in the rapidly expanding market for large,
stationary energy storage systems.”
About WattJoule
WattJoule is developing a next-generation electrical energy storage
system that uses a safe water-based liquid. The company has patented
breakthroughs that solve the historical problems that have prevented the
full commercialization of liquid flow battery storage systems.
WattJoule’s ElectriStor™ product platform will enable a wide range of
customer benefits including a reduction in electricity costs and
enabling the widespread deployment of solar and wind energy generation,
microgrids, advanced smart grid capabilities and grid reliability
improvements. More information is available at www.wattjoule.com.
