Carbon Sciences and Gas-to-Liquids Technology Offer Superior Solution to Utilize Clean Affordable U.S. Natural Gas

SANTA BARBARA, CA--(Marketwire - Apr 25, 2012) - Carbon Sciences Inc. (OTCBB: CABN), the developer of a breakthrough technology to make transportation fuels and other valuable products from natural gas, today commented that gas-to-liquids (GTL) technology offers clear advantages over compressed natural gas (CNG) with regards to environment and infrastructure.

While most experts agree that natural gas will be the world's next great source of fuel and the most certain way to achieve energy security, there is significant debate surrounding how the resource should be used. There is increasing dialogue and support for compressed natural gas (CNG) as a transportation fuel, however this use of natural gas suffers from severe infrastructure and environmental challenges.

Byron Elton, the company's CEO, stated, "With the cost of natural gas at ten year lows, there has been a steady drumbeat for utilizing compressed natural gas as a transportation fuel. A closer examination of CNG usage reveals significant problems."

While the U.S. possesses substantial reserves of natural gas, the production, distribution and processing (infrastructure) of CNG, as a transportation fuel, is not as environmentally friendly as some would suggest. The lifecycle greenhouse gas emissions for compressed natural gas engines may actually be higher than those of diesel engines due to methane being 20-times more harmful than CO2 as a greenhouse gas. Also, before CNG can be used as a fuel, new vehicles, new fueling stations and new fuel delivery infrastructure must be built. Assuming that thousands of new CNG fueling stations are built and that millions of new CNG powered vehicles are placed in service, there is no assurance that the inevitable methane leaks can be contained.

Mr. Elton continued, "It is clear that using our natural gas resources in a gas-to-liquids approach successfully addresses both the infrastructure and environmental challenges. Our catalyst and process uses CO2 and methane to produce a syngas for use in a GTL process that makes drop-in transportation fuels such as gasoline, diesel and jet fuel. This process eliminates the need for a complete infrastructure overhaul and is better for the environment. GTL is a clear winner in the natural gas debate."
