STWA Ships Oil Pipeline Efficiency Unit to PetroChina CPP/CNPC for Phase II Testing

Shipment Signifies the 'Go Forward' Point of Stage 2 in a 3 Stage Testing Process Required for Commercialization of AOT(TM) in the Largest Energy Consuming Nation in the World

SANTA BARBARA, CA -- (MARKETWIRE) -- 07/31/12 -- STWA, Inc. (OTCBB: ZERO) ("STWA" or the "Company"), a developer of applied solutions for oil and fuel delivery systems in the multi-billion dollar oil pipeline and diesel engine markets, announced today that its groundbreaking oil pipeline energy-efficiency system has been loaded for shipment to China. The unit is being transported to begin Phase II of the three-Phase commercialization acceptance process as mandated by China Petroleum Pipeline Administration (CPP). The testing is to be conducted at the CPP/CNPC PetroChina Pipeline R&D Center in Langfang, China.

The AOT™ 1.2v being shipped to Langfang, China is the same unit used for testing with the U.S. Department of Energy (US DOE) at the Rocky Mountain Oilfield Testing Center (RMOTC). This prototype unit generated successful test data at the U.S. test facility beginning in October 2011.

AOT 1.2v has begun its 5-week journey to cross the Pacific, landing in Langfang, China at the China Petroleum Pipeline Administration's Pipeline Flow Assurance Test Center in Langfang, where CPP will begin Field Loop Tests on STWA's system.

STWA recently announced the successful completion of Phase I of the commercialization acceptance process of Laboratory Testing conducted at the CPP PetroChina Pipeline R&D Center. AOT™'s effectiveness in reducing the viscosity of three of the most widely consumed crude oil grades in China was evaluated. The upcoming Phase II Field Loop test is to be followed by Phase III, the final stage, which is a commercial implementation Pilot Program.

"We are proceeding on schedule with regulatory approvals in China. Interactions with our commercialization partner, TDC, and the Chinese regulatory body, CPP, have been very productive and constructive. We look forward to AOT™'s arrival in China and the successful implementation of our Field Loop Test. In anticipation of the Phase II test's completion, TDC has already identified a 300 kilometer, 27 inch pipeline where AOT™ may be installed for the final Phase III commercial implementation Pilot Program," stated STWA CEO Mr. Cecil Bond Kyte.

CPP testing is being conducted in conjunction with STWA's commercialization partner in China, TDC. As per the terms of STWA's Cooperation Framework Agreement, TDC is responsible for the full costs of implementing the testing and certification of AOT™ with CPP.
