Bloom Stays Secretive on Day Promised for Fuel Cell Debut

Bloom Energy, a richly funded Silicon Valley startup, had promised to debut its fuel-cells today. But the company revealed little and is keeping critical parts of its business plan secret as its first product launch draws international attention.

THE PROMISE: Bloom Energy’s fuel cells promise to allow homes and businesses to generate their own power, but it’s not clear how the company will get prices down.

WHAT BLOOM IS SAYING: For the first time the company offered details about the price its customers pay for power, but experts said it wasn’t enough to gauge whether they’re saving money only because of generous federal and state subsidies.
