The Halotechnics story

2008 2009 20102007

Dr. Justin Raade begins molten salt research at Symyx

$1.5 million DOE grant awarded for molten salt R&D

Breakthrough salt mixtures discovered

Halotechnics founded, spins out of Symyx to commercialize products

2011

NSF SBIR grant awarded for CSP materials R&D

2012

$4.3 million from ARPA-E and NREL for advanced thermal storage R&D

Halotechnics Saltstream technology solves a key bottleneck in reducing emissions from thermal power plants


Rapid materials screening

• Novel materials unlock the most significant advances in technology

> Proprietary software and automated lab equipment

> Can screen up to 100 mixtures/day

> Screened over 20,000 mixtures to date


The sun is the ultimate source of energy


Solar thermal hot spots

United States:5 GW solar thermal by 2020Standalone solar with storage

China:1 GW solar thermal by 2015Solar/coal hybrids

Saudi Arabia:25 GW solar thermal by 2022Solar/gas hybrids

Saltstream 700 enables advanced solar thermal power


• Solar thermal power turns the sun’s heat into electricity

• Leverages existing turbine technology in today’s thermal power plants

• Hybridize coal plants with supercritical steam from solar energy

• Hybridize natural gas plants by pre-heating combustion air with solar energy
