Antora Energy

Inexpensive energy storage for a cleaner grid

About Antora Energy

We are building a low-cost thermal battery for grid-scale energy storage. By combining inexpensive thermal storage media at high temperatures with high-efficiency thermophotovoltaic energy conversion, we will support the widespread integration of renewable resources on the electricity grid.

The Antora Energy team is committed to transforming our energy system to one that is sustainable, secure, and accessible.

The team’s work is supported by Stanford’s TomKat Center for Sustainable Energy, the National Science Foundation, the DOE FLOW program, and a DOE ARPA-E award under the Duration Addition to electricitY Storage or DAYS program.

 

Our technology

With a marginal cost of energy capacity of < $10/kWh, our thermal battery will take excess electricity from wind and solar power plants, store it for hours or days, and deliver it back to consumers when needed. By storing energy as heat in extremely inexpensive raw materials and converting that heat back to electricity with a high-efficiency thermophotovoltaic heat engine, our energy storage system costs are low enough to make intermittent renewable energy, plus storage, cost-competitive with fossil fuels. The team has demonstrated the highest efficiency solid state heat engine in history.

Inexpensive energy storage will enable the widespread deployment of wind and solar energy, thus ensuring cheap, sustainable, and reliable electricity on a global scale while dramatically reducing carbon emissions.

Andrew Ponec

CEO

Andrew Ponec received his B.S. in energy systems engineering from Stanford University, where he researched advanced photovoltaics and power electronics. Between his sophomore and junior year, Ponec took a leave of absence to found a solar energy company called Dragonfly Systems. Dragonfly developed and commercialized a novel power electronics topology for utility-scale solar power plants, and was acquired by SunPower in 2014. Ponec led his team through concept generation, prototyping, validation testing, and manufacturing, and eventually oversaw the installation of over 10 MW of solar power plants that used the technology.

Justin Briggs

CSO

Justin Briggs holds a B.S. in physics from UC Berkeley and a Ph.D. in applied physics from Stanford University. During his Ph.D., Briggs studied next-generation renewable energy technology, with a focus on thermophotovoltaic energy conversion. He built a thermo-optical characterization platform to study the optical properties of advanced thermophotovoltaic materials at temperatures over 1200°C, and grew and validated novel materials for selective thermal emission.

David Bierman

CTO

David Bierman earned his Ph.D. in mechanical engineering from MIT, where he helped develop a novel solar-driven thermophotovoltaic converter capable of turning heat into electricity by absorbing thermal radiation using a photovoltaic cell. This innovation helped revitalize the field and was featured in a number of media outlets, including Scientific American and IEEE Spectrum.
