[More contracts for small businesses and VCSEs](https://tendernation.io/opportunities/for-small-businesses) ## About this tender Project VELAR is based on using water cracking to generate HHO gas (this is a mixture of H2, O2, HHO and electrically expanded water) which can be used for ship lubrication (to reduce drag on the water) and as a fuel / fuel additive in the engine to reduce the emissions of the engine and increase efficiency. This gas could be created at point of need / use which would give two distinct advantages. - There would be no requirement for gas storage thereby minimising the potential for accidents whilst storing dangerous gases. - By creating the gas under the vessel (at point of use) there would be no requirement for pumping the gas at high pressure under the vessel which would therefore make it more efficient. Based on our proof-of-concept trials, we believe that this technology is at TRL3. A successful project would lift this to TRL6 where we would be able to undertake a much larger project to commercialise the process alongside an original equipment manufacturer. Achieving TRL6 will be in part down to having the correct equipment to be able to move from proof of concept to demonstration and further investigation. We will also require a level of assistance in the positioning of the gas bubbles relative to the vessel's geometry and we would like the successful supplier to be able to offer this expertise. We intend to design and produce a demonstrable unit which is capable of measuring the reduced drag on the vessel. Please see the attachment for full details of how to apply.
