DEI Online Seminar Series: Biofuel Micro Trigeneration with Energy Storage for Heating, Cooling and Power of Residential Buildings

13th May 2020, 13:00 to 14:00, Via Zoom, Dr Yaodong Wang

To register for this online seminar please visit EventBrite.

The presentation is to introduce the outcomes from two EPSRC funded projects (EP/F061978/1 and EP/K004689/1). This biofuel micro trigeneration system, which is fuelled by renewable bio-oils and used to supply power, heat and refrigeration/cooling simultaneously to individual residential buildings. The system allows 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.

An engine generator is used to generate power using renewable bio-oils; waste heat from the engine generator is collected and used to supply heating and hot water. Part of the waste heat is utilised to drive an absorption/adsorption refrigerator. Off peak electricity energy generated but not used is stored in a hybrid electrical storage sub-system and is used at peak time. The results from the projects show that:

1) Overall efficiency of the micro trigeneration is around 64%; higher than a similar size of single power generation only (~ 25 %);
2) The performance of trigeneration using bio-oils is comparable with that using diesel; with the advantage of ‘net zero CO2 emission’;
3) It is feasible to use a bio-fuel trigeneration to provide electricity, heat and refrigeration for domestic users (e.g. for one household).

Dr Yaodong Wang (PhD MSc BSc CEng MIMechE), is a Fellow of Durham Energy Institute; and an Associate Professor and an active researcher working on energy systems (sustainable, clean and renewable energy) at the Department of Engineering, Durham University, UK.

He has over 20 years’ experience working on 26 research projects as a Researcher (RA); Principal Investigator and Co-investigator including: biofuel or biomass trigeneration and cogeneration with energy storage; biomass gasification, anaerobic digestion and combustion; energy systems such as biomass/coal thermal power plants; renewable energy systems (wind, solar, biomass, water/hydropower); advanced cycles to reduce emissions from energy systems (Miller Cycle petrol and diesel engines; Flameless Oxidation to reduce NOx emissions from gas turbine and power plant); biofuel petrol/diesel engine; organic Rankine cycle; thermal energy management in processing industries; building energy saving using passive and active methods. He has over 160 papers published in peer-reviewed journals and international conference proceedings.
