So it stands to reason if a Japanese manufacturer of a flexi-fuel engine, which does not have any acceleration problem, can sell it in Brazil, it stands to reason that it will sell in India," the minister said. A transition to bio fuels is also good for agriculture. "By 2040 you will see fossil fuels fading away and green hydrogen taking its place," he added.
