• MO5Si3, MoSi2, and MoB.
• wherein the MoSiB composite tubing component comprises a MoSiB composite tube having a first coating, wherein the MoSiB composite tube is configured to flow heat transfer material in a first loop that includes a first section of the MoSiB composite tube that collects solar energy that thermally communicates the solar energy to the heat transfer material;
• wherein the solar receiver is in thermal communication with a thermal storage system in a second section of the MoSiB composite tubing through a heat exchanger that exchanges heat between the heat transfer material in the MoSiB composite tube in the first loop and a secondary heat transfer fluid in a second loop that is stable at temperatures above 700° C. and comprises super critical CO2, Ar, or He;
• and
• wherein the thermal storage system comprises a heated tubing system and a thermal bed, wherein the secondary heat transfer fluid is contained in the tubing components, wherein the heated tubing system is configured to exchange heat with the thermal bed to store thermal energy, wherein the thermal bed comprises rocks, castable refractory, or high temperature bricks.
