Currently, the majority of global R&D activities in flywheel KERS is concentrated in Europe especially in UK. The British government-backed Technology Strategy Board sponsored 
'Green Research' programme involving flywheel KERS in three projects. These projects intend to demonstrate the potential of flywheel KERS in fuel savings, operation practical and accumulate key technologies:
(1) Project “Flybus”: to demonstrate the potential to retro-fit buses and commercial vehicles with flywheel KERS and this project is led by Torotrak.
(2) Project “KinerStor”: applying flywheel KERS to light-duty hybrid vehicles to demonstrate the potential of 30% fuel savings with equivalent CO2 reductions and at an economic cost. This project is led by Ricardo.
(3) Project “FHSPV”: In this project, a Flybrid flywheel KERS was fitted into the new Jaguar XF to demonstrate its fuel savings and operation practical in premium vehicles.

Because of accidents occurred in the process of R&D in flywheel battery in 1970-80’s and its potential unsafe factors, the US and Japan always remain skeptical of flywheel technology. In Dec. 2011, by the influence of an assessment report named “Flywheel High Power Energy Storage Technology for Hybrid Vehicles” accomplished by Oak Ridge National Laboratory (ORNL) assigned by Department of Energy (DOE), the US government realized the huge potential of flywheel KERS in business and its high maturity in production. As the fact that it is Europe especially UK is leading this cutting-edge technology currently and in light of the strong endorsement given to flywheels by FIA in October 2009, this report recommended DOE to give flywheel KERS a renewed consideration in its whole new energy development structure.

Before 2012, the activities in flywheel KERS occurred in China were technology tracking only, but a Chinese company named Changzhou Haike New Energy Technology Co., Ltd. (hereafter say Haike ) began to challenge this peak of cutting edge technology after its establishment in Jan., 2012. Haike is dedicated in the R&D and industrialization of “electrical type” of flywheel KERS, it utilizes innovative method of integrating flywheel, control motor, drive train into vehicle power train via a planetary gear set and implements electrical continuous various transmission by an innovative system control strategy. It realizes good performance featured by flywheel KERS by the approaches which are easy to be in mass production.
