Research opportunities to advance solar energy utilization
TLDR
Lewis reviews the status of solar thermal and solar fuels approaches for harnessing solar energy, as well as technology gaps for achieving cost-effective scalable deployment combined with storage technologies to provide reliable, dispatchable energy.Abstract:
Major developments, as well as remaining challenges and the associated research opportunities, are evaluated for three technologically distinct approaches to solar energy utilization: solar electricity, solar thermal, and solar fuels technologies. Much progress has been made, but research opportunities are still present for all approaches. Both evolutionary and revolutionary technology development, involving foundational research, applied research, learning by doing, demonstration projects, and deployment at scale will be needed to continue this technology-innovation ecosystem. Most of the approaches still offer the potential to provide much higher efficiencies, much lower costs, improved scalability, and new functionality, relative to the embodiments of solar energy-conversion systems that have been developed to date.read more
