Carbon Sciences Catalyst Test Results Point to Possible $6 Billion of Annual Economic Value

SANTA BARBARA, CA--(Marketwire - Mar 5, 2012) - Carbon Sciences Inc. (OTCBB: CABN), the developer of a breakthrough technology to make transportation fuels and other valuable products from natural gas, today announced that commercial test results of its high performance catalyst point to a substantial market opportunity. Ongoing commercial tests show stable operation and high conversion at a reduced steam to natural gas ratio of 1.5. A lower natural gas ratio can reduce steam usage up to 50% resulting in higher production at a lower cost for steam reforming plant operators and an annual gain in economic value of approximately $6 billion.

Steam reforming of natural gas is the primary method for producing over $150 billion per year of hydrogen for use in making the world's fertilizers and as a critical reactant in fuel and chemical processes. There are approximately 2,000 steam-reforming plants around the world using older generation catalysts that require a steam to natural gas ratio of 3. By reducing the steam to natural gas ratio to 1.5, less steam is used and more natural gas is processed in a greener and cleaner solution that saves energy costs, increases profits and reduces CO2 emissions.

Byron Elton, CEO of Carbon Sciences, commented, "These are the most exciting test results we've observed to date. Encouraging results this early in the test cycle gives us a greater sense of confidence that a commercial grade catalyst is well within our reach. Steam is a very expensive cost component in existing natural gas steam reforming plants. We estimate that by reducing steam usage by 50%, we can deliver $1.3 million per year in energy savings and $3.5 million per year in additional profits to a medium size steam reforming hydrogen plant -- with minimal equipment changes."

Elton continued, "In the $150 billion per year hydrogen market, we estimate we can deliver approximately $6 billion per year of economic value to operators of steam reforming plants. A big market provides a big opportunity and our business model calls for collecting a royalty fee for the use of our breakthrough catalyst technology. By reducing the cost of natural gas reforming processes, we 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. Clearly, this is a very big opportunity."
