Abstract

Heliostats with active adjustment of surface shape and provision for highly accurate orientation are being prototyped for use with receivers with secondary reflectors, to focus sunlight at concentrations as high as 4,000 suns and at high power, > 1 MW. One application is making green hydrogen from water. Heliostats in a field will each form a disc image of the sun, all centered on a compound paraboloidal concentrator (CPC). A mechanical linkage to the cross axis drive of target-axis mount drive continuously adjusts the shape of each reflector through the day, as needed for the changing angle of incidence.
