| Hydrogen Conversion | Low | High | Moderate | Long distance transport |
Large Scale Solar Power Transportation
More significant solar power installations require different methods to distribute their electricity-sharing capabilities, which is equally true for commercial systems as well as those established by a utility company. They would typically involve the use of Concentrated Solar Power (CSP) systems. These systems consist of collections of mirrors which collect the sun’s rays to heat fluids and create steam with which turbines are turned and subsequently produce electricity. Resulting currents are transferred on high voltage lines, and then disseminated to remotely power various places.
