How Mirrors Could Solve our Energy Problem

Please don't take this the wrong way.  These technologies are amazing and are significantly advancing our understanding of possible solutions for our climate crisis.  However.....  It is extremely frustrating to see YouTube channels providing information to the general public which exposes the positive side of the story and not the negative.  The Ivanpah towers in California are marvels of engineering.  What people are not told is that they do not only produce electricity with solar heat but must also use natural gas (methane) to keep the system operating above a certain temperature at night.  With the most complete data I have for 2015 - 2018, Ivanpah used nearly 1,490,000 MWh of natural gas to produce 126,031 MWh of electricity.  That's about 8.5% efficiency.  Most modern natural gas power plants are CCGT types.  The same amount of natural gas would typically produce about 815,000 MWh of electricity.  That is at 55% efficiency and is 6.4x as much power as Ivanpah.  In those 4 years, Ivanpah would produce approximately 270,000 metric tons of CO2 which would be about the same for a CCGT plant with 6.4x more electricity to show for it.  On another note, hydrogen cars are a perfectly clean way to drive producing only water and heat when burned.  This only works if hydrogen is easy for us to create, which it isn't.  For every 1 metric ton of hydrogen produced, approximately 6 metric tons of CO2 are entering our atmosphere.  Green minded people may say we can capture that CO2 and pump it into deep wells in the ground.  Yes we can but this would add 80 - 90% to production costs.  This is not a realistic scenario.  Once again, great ideas but everyone needs to know both sides of the story.
