Photonics and energy sciences are yielding advances that can open paths for conceptually new energy conversion technologies. I will discuss three such “grand challenge” pathways. A first is challenging conventional wisdom and laws about the properties of the apparently incoherent emission of thermal radiation. A second challenge is that of generating chemical fuels from sunlight, suitable for aviation and heavy transport use, from advances in photoelectrochemical water splitting and carbon dioxide reduction. This requires new approaches to solar fuels systems design with unprecedented efficiency, durability, and chemical selectivity. The third challenge is space solar power innovation, powered by ultralight, inexpensive photovoltaics, flexible structures, and phased arrays. Space solar power technology can potentially enable generation of dispatchable, baseload solar electricity that doesn't exhibit the intermittency of conventional solar photovoltaic systems, representing an approach to baseload solar power generation anywhere on earth.
