"The Silencing Of Science"

...For those who've forgotten, hydrogen fuel cells were, three State of the Unions ago, the thing that was going to save Americans from their oil addiction and stop the auto emissions that help cause global warming. Nowadays switch grass and biomass are the hot alternative fuels, but back in 2003, the president won applause for proposing "$1.2 billion in research funding so that America can lead the world in developing clean, hydrogen-powered automobiles." On Capitol Hill, there were demonstrations of one such "Freedom Car," and the president called on scientists to be "bold and innovative" in their hydrogen research.

Unfortunately for the authors of "Potential Environmental Impact of a Hydrogen Economy on the Stratosphere," their research, while bold and innovative, didn't exactly mesh with the hype. According to their model, tiny leaks from hydrogen cells, if such cells are ever mass-produced, could cause serious environmental damage. But they made no suggestion of inevitability: One of the study's authors, John Eiler of Caltech, pointed out that foreknowledge of potential environmental problems could "help guide investments in technologies to favor designs that minimize leakage." Presumably thinking along the same lines, NASA, which had helped pay for the research, prepared a news release and news conference on the paper.

Abruptly, both were canceled. Although "we often hear that releases are held up for political reasons," one NASA employee told me, "that one was a surprise: It went all the way to the top and then got killed." In fact, the release and the conference were "killed" by the White House Office of Science and Technology Policy. An official there told me this was because the office wanted to give Energy Department scientists a chance to respond to the study before it was publicized: "Our role is to facilitate interagency cooperation." Coincidentally or not, it also happens that Spencer Abraham, then the energy secretary, was that same week preparing to depart for Brussels, where he was to tell Europeans that U.S. hydrogen research proved the Bush administration cared about the environment.
