Purdue is set to receive almost $20 million from the National Science Foundation to run a research center studying what its leaders are calling “bridge fuels” – in other words, fuel made from gas that's trapped in underground rock. It's extracted through hydraulic fracturing, or fracking. The researchers say it’ll be needed to satisfy the country’s demand for oil until renewable resources like wind and solar become dominant in the future.

But there was no mention of the “f-word” – fracking -- during a public celebration of the grant or in any of the promotional materials concerning it.
