Summary Energy harvesting from pavements has been a topic of extensive research in the recent past. This domain has attracted not only the research community but also the industry and governmental authorities. The various sources exploited for energy harvesting from pavements and roadways are solar radiation, mechanical energy dissipated due to moving vehicles and pedestrians, geothermal energy, rainwater, and wind. This article presents an exhaustive and updated review of all potential means of energy harvesting from these sources. Following the introductory section, the article sequentially covers the energy harvesting methods and their research progress, materials, development of practical systems, commercial status, comparison of technologies, challenges, and concluding remarks. This study reveals that there is wide scope for further research and feasibility studies, which could lead to a wide‐spread implementation of the various technologies for energy harvesting from pavements and roads.

“…For vehicles used in the UK, the fuel cost is based on the average annual mileage of 12000 miles for the first year new cars, 10000 miles the second year and 8000 miles per year for the following years [19]. ICE vehicles' average fuel consumption is currently about 0.09 litre/mile, compared to 40% of HEV's saving which was reported by NREL (National Renewable Energy Laboratory) [20] and Ting et al [21]. From the study in the last section, EER's 20% saving on fuel consumption is selected.…”

Differing from those traditional vehicle exhaust heat recovery systems which just provided thermal energy directly for cabin warming, integrated Exhaust Energy Recovery (EER) which is researched and developed mainly in recent years aims to convert exhaust thermal energy to mechanical or electric energy for increasing the total thermal efficiency and the total power of powertrain. In the study presented in this paper, an analytic model was built for examining the environmental and economic benefits of integrated EER systems. Then the improvement on the total powertrain efficiency and net reduction of CO 2 emissions were investigated, in terms of the average vehicle used in the UK. Results show that, for light duty vehicles fitted with thermal cycle EER system, the cost increase could be paid back in 10.1 years and CO 2 emission could be paid back in just 1.9 years, compared to Hybrid Electric Vehicle's (HEV's) 11.9 years and 1.4 years for cost and CO 2 emission, respectively. When the annual fuel price increase is considered, the cost pay-back is reduced to 8.1 years for EER vehicles and 8.9 years for HEVs. Higher mileage vehicles will have more obvious advantage for fitting EER system. When doubled annual mileage is considered, EER system can reduce the cost and CO 2 emission pay-back times to 2.7 years and 0.6 years, compared to HEV's 8.5 and 2.7 years, respectively.

A Self-Contained Roadway Kinetic Energy Harvesting System for Energy Recovery

Kinetic Energy Harvesting (KEH) systems have been applied to various maintenance-free electronic devices. One of the potential applications of such a system is harvesting a decent amount of kinetic energy generated by road vehicles. Although researches have been conducted on roadway KEH system, it is worthwhile to improve the system in order to convert more energy without worsening the driving experience. This work consists of design of a piezoelectric KEH transducer (Cymbal transducer), and improvement of the KEH circuit. The optimal geometry of each Cymbal unit is determined by the utilization of Finite Element Analysis. After studying several recently introduced piezoelectric KEH circuit topologies, a preferred topology has been adopted for a novel KEH circuit design.A voltage peak detection function and an energy storage unit voltage hysteresis function have been included in the circuit. The circuit has demonstrated a higher energy harvesting efficiency (12.28%) compared to competitors during tests.iii Acknowledgements Firstly, I would like to express my sincere gratitude to my research supervisor, Prof. Jie Liu and Prof. Junjie Gu, for their continous encourangment and excellent academic guidance. It was they who led me into a brand-new research field that I found extremely interesting. The weekly research meetings with them are always instructive, and the research experience gained with them will benefit me for the rest of my life. In the meantime, I would like to express my appreciation to our industry partner, BW Services Inc., for their financial support to this research project.My special thanks go to my research team member, Matteo Louter, who has always been by my side during the initial design, the tedious fabrication, and the chilly field tests. He has provided me with so much assistance, and the research experience would not be enjoyable without him. Many thanks should also be given to the Machine shop technologist, Alex Proctor, for his patient operation guidance during the fabrication process, and to the hydraulic load frame technologist, David Raude, who has spent a lot of time helping us do the loading tests, and his sense of humor is always pleasant.Last but not least, I am very grateful to my parents in China for their endless love over these years, and for giving me the opportunity to have this precious overseas study experience.iv
