Carbon Sciences Inc. (OTCBB: CABN), the developer of a breakthrough technology to make transportation fuels, hydrogen and other valuable products from natural gas, today announced successful test results of its steam methane reforming catalyst at high pressures that simulated the conditions of industrial hydrogen production plants. The company's catalyst has now been tested at high temperature and high pressure, critical operating conditions required for commercial viability.

Steam reforming of natural gas is the primary method for producing over $150 billion per year of hydrogen for use as a critical reactant in fuel and chemical processes and in making the world's fertilizers. The company's high performance steam reforming catalyst is designed to lower the steam to natural gas ratio, thereby lowering the cost and increasing the throughput of hydrogen production in existing plants. Industry operators typically use 3:1 steam to carbon. The company recently reported test results at a 1.5:1 steam to carbon ratio and described the favorable economic implications of reducing this ratio. The company estimates that its drop-in replacement steam reforming catalyst can deliver nearly $6 billion of annual economic value to the hydrogen industry.

Carbon Sciences previously announced that its steam reforming catalyst performed successfully with high and stable conversion at 850 degrees Celsius. Recent tests provided valuable data for the development team to use in creating enhancements to the catalyst. The company now reports that the latest version of its catalyst tested successfully with high and stable conversion at a pressure of 15 bar and a temperature of over 900 degrees Celsius.

Byron Elton, CEO of Carbon Sciences, commented, "High temperature and high pressure performance are the two big challenges we know we have to overcome for commercial success. Through persistence and innovative engineering, our development team has been successfully addressing those challenges. While there is more work to be done before we can call our catalyst a commercial success, the recent accomplishments bring us much closer to our goal of delivering a drop-in replacement catalyst for over 2,000 natural gas-to-hydrogen plants worldwide. It's remarkable to see how much progress our development team has made during the past 18 months."

About Carbon Sciences, Inc.

Innovating at the forefront of chemical engineering, Carbon Sciences is developing a breakthrough technology to make cleaner and greener transportation fuels, hydrogen and other valuable products from natural gas. Our highly scalable, clean-tech process will enable the world to reduce its dependence on petroleum by transforming abundant and affordable natural gas into gasoline, diesel and jet fuel, and other products, such as hydrogen, methanol, pharmaceuticals, solvents, fertilizers, pesticides and plastics. The key to this process is a breakthrough catalyst that can reduce the cost of reforming natural gas into synthetic gas (syngas), the most costly step in making products from natural gas.
