The contribution of the aviation sector to global greenhouse gas emissions can be tackled with a net-zero fuel formulated at Worcester Polytechnic Institute.
Developed through modeling and computation analysis, the sustainable fuel consists of a slurry of magnesium hydride, which releases water vapor and magnesium oxide nanoparticles on combustion. The magnesium oxide can react with carbon dioxide and water in the engine plume or atmosphere to form magnesium carbonate or magnesium bicarbonate, effectively capturing the greenhouse gas.
When tested with n-dodecane as a surrogate hydrocarbon jet fuel, the magnesium hydride slurry was determined to afford planes the range for long-haul flights, due in part to the lower volume required for combustion than a typical aviation fuel.
The researchers theorize that using a biofuel as the hydrocarbon surrogate in this slurry with magnesium hydride could potentially lead to net negative emissions.
The research is published in the journal Fuel.
For Attention of respected experts, I am happy to share that one of my clients is already manufacturing a novel Herbal Additive for any type of fuel including ATF which would reduce emissions of GHGs by 98% and increase fuel efficiency by 40 to 60%. Thus, the basic fuel consumption can be drastically reduced and a giant step towards Carbon Neutrality and CDM can be achieved. I need support to introduce it in aviation and support for test/trial to be conducted about avoiding formation of ICE crystals which leads to blockage of fuel path turning into disaster to the concerned Aircraft.
