US-headquartered GlassPoint partnered with Searles Valley Minerals in California to develop a 750 MW solar collector system. The project was designed to generate 250 MWt of steam, supplying about 60% of the company’s 1.2 million pounds per hour demand. The project included molten salt thermal storage with 18 hours of capacity and was expected to take four years for permitting and construction. Solar collectors were enclosed in polymer film houses, reducing costs, enabling larger troughs, and protecting them from wind and dust. Steam output was designed at 1,400 psi and 900°F, delivered through a six-mile pipeline from company-owned land, with subcontractors engaged for pipeline works. Despite added pipeline losses, efficiency remained high. The system was planned to deliver solar steam at costs competitive with fossil fuels under a long-term off-take agreement.
