BMT-CES: Biofuel Micro-Trigeneration with Cryogenic Energy Storage

Lead Research Organisation: University of Leeds
Department Name: Inst of Particle Science & Engineering

Abstract

This proposal is concerned with developing a trigeneration system (power, heat and refrigeration) which is fuelled by renewable fuels and can be used in the domestic environment or scaled up to be used in larger, industrial based environments. The system would allow heat, power and refrigeration to be produced locally, where it is needed, using a novel energy storage system and a novel control and optimisation system to produce high efficiency operation.A power generator will be used to generate power using renewable fuels (biofuels). Waste heat from the generator would be collected and used to supply heating and hot water. The waste heat would also be utilised to drive an absorption/adsorption refrigerator. Off peak electricity energy generated but not used will be stored in the electrical storage systemThe project will link together specialised personnel in the UK and China who have the critical expertise necessary to bring together all aspects of this challenging project. The project will also benefit research links between the UK and China. There is substantial potential demand for the system in the UK, China and other parts of the world as the results would provide benefits to government, academia, manufacturers and consumers.

Description This is a collaborative project between universities of Leeds, Newcastle and Ulster. Through the project, we (Leeds team) developed, for the first time, a cryogenic energy storage system using carbon dioxide as the storage medium - an extension of the famous liquid air energy storage technology, built a lab scale demonstration unit and tested the performance of the system. The system operates at a pressure between 10bar and up to 70 bars to prevent the formation of solid particles. We have also built a single cylinder (~5kW) and a multiple cylinder (~15kW) piston engines for the system and also associated control programme. The demonstration system is substantial piece of kit, which has been used not only as a means for testing the performance of the system, but also for further research in cold storage materials, cold storage devices and system integration and optimisation.
Exploitation Route The route for the findings to be used was defined at the beginning of the project, namely to disseminate to industry as well as to publish through academic papers. The work has led to a number of publications and substantial subsequent projects from e.g. Air Products, Highview Power Storage, Royal Academy of Engineering, SGRI and CRRC etc. The work has also led to two sets of engines being sold to an overseas research organisation to use as research engines in their thermal energy storage system.

Description The work is closely related to the well-known liquid air energy storage technology (LAES) invented by my team some 11 years ago when I was in Leeds. It has been found that a large scale (>15-25MW) standalone LAES system has a round trip efficiency ~60% and the efficiency drops substantially when the system is below some 1MW. The knowledge and experience gained from the project have been used to improve the efficiency of small scale LAES system. In addition, the engines developed through the projects and associated control and monitoring programmes are potential products, awaiting further commercial development.
