Competitive Advantage: SOFC vs Solar / Wind:

Confidential 7 Competitive Advantage: SOFC vs Solar / Wind Solar , while clean, is only available 18% of the time on average. Dirty, grid electricity (“brown power”) is required the other 82% of the time. SOFC is available 24 hours a day; making it a cleaner, cheaper alternative

Bloom Energy Value Propositions:
