Mitsui Engineering and Shipbuilding Co. LTD. and Dynamotive Energy Systems Corp. Enter into Memorandum to Test BioOil as an Alternative Fuel in Slow and/or Medium Speed Diesel Engines

Mitsui Engineering and Shipbuilding Co. LTD. (MES), and Dynamotive Energy Systems Corp. (Dynamotive), announced that they have entered into a Memorandum of Understanding to form a new partnership that will serve as a platform to test, develop and market BioOil for application in Slow and/or Medium Speed Diesels globally.

Cooperation between the parties follows positive results achieved in preliminary testing which was conducted in 2009. Preliminary tests concentrated on establishing the suitability of BioOil use for the specific application as well as technical reviews of Dynamotive’s pyrolysis technology which included visits to the Company’s BioOil production facilities in Canada by MES experts.

MES and Dynamotive recognize that responding to global warming, protecting bio diversity, power generation and access to energy are global issues that must be addressed through the application of sustainable practices. The parties expect a growing trend in carbon reduction through the use of biofuels and growing customers interest in biofuels. As such the Companies envisage the following activities to be conducted in 2010.

a. Testing and evaluation to determine the suitability of DynaMotive BioOil as a mixing (blend) component and/or an alternative fuel in slow and / or medium speed diesel engines at MES facilities.

b. Commercial testing in field initially in stationary power plants applications and at second stage in marine applications.

Following these activities and subject to satisfactory results, the parties intend, through good faith negotiations, to enter into a definitive agreement to formalize their collaboration. The parties would utilize best endeavors to enter into such agreements by September 30^th, 2010.

The Definitive Agreement will contain, among other things, terms for use of facilities, covenants and other terms and other customary conditions.
