By using renewable solar energy and a process of solar conversion that he patented called Solar Thermal Electrochemical Photo (STEP) energy conversion, Dr. Licht is able to easily extract pure metal iron from the two prevalent iron ores, hematite and magnetite, without emitting carbon dioxide. Today, the commercial iron industry emits an estimated 6.8 trillion tons of carbon dioxide into the atmosphere each year.
“STEP is a new renewable energy process that can capture carbon and makes the materials that society needs without emission of carbon dioxide. We’re developing processes to return the atmosphere to pre-industrial levels of carbon dioxide,” said Dr. Licht.
The process of producing iron free of carbon dioxide emissions is a culmination of more than 20 years of research by Dr. Licht. Through his years of study, Dr. Licht came to understand the efficient use of sunlight and the chemistry of iron, and found that iron ore at high temperatures is significantly more soluble than previously thought. In his most recent research, Dr. Licht found a new way to use electrolysis – a process that uses electricity rather than chemicals to create a reaction – to covert iron ore to iron metal. This high temperature electrolysis requires little energy, and can be powered through conventional or renewable energy sources to reduce or completely eliminate CO2 emissions. When powered by STEP, the electrolysis process is carbon dioxide free, creating no global warming gas emissions when converting the ore into metal. By using both solar thermal energy and visible sunlight, the STEP process converts more solar energy than the best solar cells, as it uses excess solar heat (energy discarded by solar cells) to drive iron production.
Dr. Stuart Licht is a chemistry professor at the Columbian College of Arts and Sciences at the George Washington University. He is an expert in renewable energy chemistry, physical and analytical chemistry. Much of Dr. Licht’s research leading up to this discovery has been published in journals such as Science and Nature. Dr. Licht first presented the STEP process and demonstrated that it can efficiently capture carbon in the article “A New Solar Carbon Capture Process: Solar Thermal Electrochemical Photo (STEP) Carbon Capture” published in the July 14, 2010 issue of The Journal of Physical Chemistry Letters. His work with the STEP process is ongoing. Dr. Licht is currently working to develop solar jet fuel and synthetic diesel as well as producing bleach free of carbon dioxide emissions. The iron study was performed at the Licht laboratories at GW together with Dr. Baohui Wang, a visiting professor from the Northeast Petroleum University in China, and was published in the August 23, 2010, online edition of Chemical Communications.
Established in 1821 in the heart of the nation's capital, GW's Columbian College of Arts and Sciences is the largest of the University's academic units with more than 40 departments and programs for undergraduate, graduate and professional studies. Columbian College provides the foundation for GW's commitment to education, research and outreach, providing courses ranging from the traditional disciplines to a wide variety of interdisciplinary and applied fields for students in all the undergraduate degree programs across the University. An internationally recognized faculty and active partnerships with prestigious research institutions place Columbian College at the forefront in advancing policy, enhancing culture and transforming lives through scientific research and discovery.
In the heart of the nation's capital with additional programs in Virginia, The George Washington University was created by an Act of Congress in 1821. Today, GW is the largest institution of higher education in the District of Columbia. The University offers comprehensive programs of undergraduate and graduate liberal arts study, as well as degree programs in medicine, public health, law, engineering, education, business and international affairs. Each year, GW enrolls a diverse population of undergraduate, graduate and professional students from all 50 states, the District of Columbia, and more than 130 countries.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
