    Biofuels: An investigation into the use of Pure Plant Oil as a replacement for Marine Diesel

    The use of pure plant oil (PPO), also known as vegetable oil, as a diesel fuelextender or as a total fuel substitute is known. The concept gained popularity during the fuel crisis in the 1970’s although engine technology at this time was relatively basic. The concept today has two primary drivers for land transportation: cost reduction and environmental footprint. The use of recovered and suitably processed used cooking oil (UCO) can offer further substantial atmospheric carbon dioxide (CO2) mitigation together with a reduction in other regulated exhaust pollutants, such as sulphur dioxide, as well as additional cost savings compared to virgin PPO,.Regenatec has developed technology which retro-fits to diesel engines and allows them to be fuelled by diesel or PPO or UCO. This technology is found in products being sold to owners of land based vehicles, both commercial and domestic. Initial trial work performed by Regenatec on land based vehicles has shown promising results. This project investigated the use of PPO in a trawler, the Jubilee Quest, based in Grimsby, UK, operated on PPO during the Autumn of 2006. The aim of this trial was a technical investigation of the technology and PPO: it was not designed to be a commercial deployment. The use of PPO (and even UCO) is currently commercial unviable in UK marine applications due to the economies of scale enjoyed by the petrochemical industry. (The use of PPO and UCO is only viable for land based vehicles because of a duty rebate currently enjoyed by bio-fuels.) As biofuels start to scale and when the environmental costs of fossil fuels are fully reflected in the cost of the product, it is anticipated that biofuels will become economically viable. As a key part of this project, Regenatec developed their technology into a system to be used at sea by a trawler. Their dual tank system is under electronic control to automate the use of PPO in a diesel engine. This has significant advantages over existing, less sophisticated technology. The engine is started on conventional marine diesel (or biodiesel) and then automatically switches over to the lower cost, more environmentally friendly PPO. The automation greatly improves the ease of use for unskilled operators and removes the potential for engine damage when compared to manual control. Additionally, Regenatec is heavily involved in fuel additive work investigating what fuel additives commonly used to enhance the technical and environmental performance of mineral diesel are applicable to PPO and UCO. This work is being undertaken under Confidentiality Agreement in conjunction with a leading mainstream additive manufacturer. An ‘additive pack’ was not fully developed and therefore not available for field deployment during this project. However, lab work and land based field trials in this area have provided encouraging feedback.

    Biofuel for the Fishing Industry Final Report

    Since 2004 the price of diesel fuel oil has increased significantly, causing many fishing vessels to become unprofitable. At the same time biofuels has increased in prominence as a long-term replacement for non renewable fossil fuels. This report details a research and development project to investigate the potential of biofuels for the fishing industry, which took place between October 05 and Jan 08. In the project two types of fuel are studied, biodiesel and pure plant oil. Over the course of the study both fuels were tested on land and at sea and proved to be technically successful. The main driver for uptake of the alternative technology in the fishing industry is economic and our study found that in most cases fossil fuels will remain more cost effective for fishing business in the short to medium term. That said there may be some opportunities in more remote communities where used vegetable oil is available and the cost of transporting diesel oil into the area push the price above that of locally produced biofuels. In terms of environmental credentials biofuels are generally sustainable but there are a number of issues which perspective purchasers need to consider which may overall green credentials of their biofuel.

    Bio-fuels for the fishing industry_Camborne School of Mines Report

    This report details work carried out to investigate the performance of biofuels in marine diesel engines, relative to the use of fossil petrodiesel. The scope of work ultimately included: 1) The installation of a dynamometer test facility, equipped to run diagnostic and simulated operational duty cycles on marine diesel engines.
