The necessary shift from fossil based energy use creates both challenges and huge opportunities. The replacement energy sources are necessarily diverse, and inevitably less convenient, requiring a multitude of new technologies in their conversion and use, while energy conservation and emissions mitigation have arguably an even greater role in lessening the impact of our energy activities.

Longma Clean Energy specialises in developmental research with application to renewable CHP and biofuels, working in partnership with universities and multinational companies in the UK and China.

We are currently developing advanced processing technologies within bio-oil conversion. Free fatty acids found in bio-oils, are often at levels that significantly impact processing costs and yield in biofuel manufacture, or can cause engine failure when the oils are used straight (as SVO/PPO). Longma are developing a low cost, catalyst free technology to convert FFAs into biodiesel. The technology is seen as an integral component in a total feedstock pre-treatment system that can convert poor specification oils, for example from pyrolysis, to a high quality standard oil feedstock.

The limited availability of feedstock with low environmental cost is a major hurdle the embryonic biofuels sector must overcome. However, there is huge potential in underutilised biomass waste and woody feedstocks. Pyrolysis is one technique that could be used to convert biomass into liquid and gaseous forms to be used for road transport fuel or power generation. Longma are developing a system that converts waste glycerol from biodiesel manufacture, into a useful liquid fuel, using a novel pyrolysis technology that offers a high degree of control in the reaction environment.

Fuel additives are now routinely used for fossil fuels to improve fuel performance and protect engines. Biofuels present some unique challenges and therefore require a different package of additives, and generally benefit more greatly from their use. For the past three years Longma has been developing additive packages for SVO used in road vehicles and CHP applications, as well as for biodiesel for road use.

Our additive for vegetable oil based biofuels VPlus7 is now available – follow link for details.
