SPARKS, Nev., May 18, 2005 – Dr. Raad Alkadiri, a country risk specialist with the energy advisory firm PFC Energy, Inc., and an expert in global energy policy, has joined the board of SulphCo, Inc. (OTC Bulletin Board: SLPH), the company announced. SulphCo is a leader in developing and marketing high-powered ultrasound technology and equipment for the petroleum industry.

Alkadiri returned to PFC Energy last year after ten months as policy advisor and assistant private secretary to the United Kingdom’s Special Representative to Iraq. In this role, he assisted in shaping UK policy toward Iraq during the occupation, as well as planning Iraq’s transition to sovereignty. He was made an Officer of the Order of the British Empire for his work in Baghdad.

At Washington, D.C.-based PFC Energy, an international strategic advisory firm on global energy, Alkadiri is director of the firm’s markets and countries group and heads its Iraq advisory service. Alkadiri focuses on the political, economic and sectoral factors that influence oil and gas producing states, particularly those in the Middle East.

“We are very pleased to have the benefit of Raad’s global expertise and macro perspective of the energy sector to assist in guiding us as we continue to market our ultrasound process around the world,” said Rudolf Gunnerman, SulphCo chairman and chief executive officer.

“I am delighted to be asked to join the SulphCo board and I am very excited about the company’s future. I believe that the technology it has developed is revolutionary and will transform the oil industry,” said Alkadiri. SulphCo has developed the patented Sonocracking™ high-powered ultrasound process to upgrade sour heavy crude oils into sweeter lighter crudes. SulphCo’s ultrasound process increases the distillate yield while at the same time reducing sulfur and nitrogen content, producing more usable oil per barrel of crude.

 Prior to joining PFC Energy in 1998, Alkadiri was Middle East analyst at the UK-based consultancy Oxford Analytica, where he focused on political and economic developments in the northern Persian Gulf states. From 2000 to 2001, he was associate professor at the School of Advanced International Studies, Johns Hopkins University. He was a teaching fellow of politics at the University of St. Andrews from 1990 to 1991.

Alkadiri holds a D.Phil. from St. Antony’s College, Oxford University, and M.Phil. and M.A. degrees from the University of St. Andrews. Fluent in Arabic, he has authored numerous articles on Iraq and Middle East affairs.
