Most of the propulsion and power systems use liquid fuels repre- senting 19 million barrels of liquid fuel per day alone in the USA and about 5 times more this amount worldwide.

Theworldpopulationhasreachedover7.8billionandisprojectedtoincreaseby more than 25% to 9.9 billion by 2050. The worldwide energy supply in 2019 was about170,000TWh,or580quads(quadrillionsBTU),andisexpectedtoincrease to815quadsby2040.PerIEA,ifwecontinuealongthecurrentpath,withoutany additionalpolicychanges,theenergydemandwillriseby1.3%peryearupto2040.If thepolicyintentionsandtargetsstatedbymajorenergyusernationsareimplemented, v vi Preface thisenergydemandratecoulddecreaseto1%peryear.Whileconsiderableprogress isbeingmadetoshifttorenewableenergysources,fossilfuelsareexpectedtoprovide 75%oftheworld’senergyin2040.Whiletheenvironmentisalreadyunderstress, eitherof thesescenarios places asignificant additional burden ontheenvironment with a somewhat slower rise in emissions but still far short of sustainability and safety. Therefore, we urgently need a sustainable development scenario that maps out a way to meet energy demand goals, requiring rapid and widespread changes acrossallenergysectors.Thecurrentandforeseeablecleanenergytechnologiesare not likely to provide the answer.

The workshop’s objectives were to promote inter- national collaborations and disseminate knowledge related to safe and sustainable energy initiatives and technology development. The workshop attracted over 100 participants from different academic and research organizations and representa- tives from governments, industry, and academia. Many world-renowned scientists andresearchers fromJapan,Malaysia,Thailand,Saudi Arabia,theUK,USA,and India presented their latest research and development findings and shared ideas, informal talks and informal technical exchanges.

The Chief Guest at the workshop was Dr. Satish Kumar, Director of National Institute of Technology, Kurukshetra, Haryana,India,whoprovidedawealthofinformationfromhisrich,extensiveprior experiences in various leadership positions at Defense Research and Development Organization (DRDO), India. Renowned international authorities delivered some 28 invited lectures in their specific expertise on the various topics covered at the workshop.Twenty-fourtopicsonadvancesinenergyandcombustion,emphasizing safetyandsustainabilityfromtheselectedauthorities,weredelivered.Subsequently, they contributed a chapter on their topic, which are included in this book.
