In 1905 a power plant was set up in , a town which is a suburb of Reykjavík. Reykjavík wanted to copy their success, so they appointed Thor Jenssen to run and build a gas station, Gasstöð Reykjavíkur. Jenssen could not get a loan to finance the project, so a deal was made with Carl Francke to build and run the station, with options for the city to buy him out. Construction starte.

How does solar energy storage work?
Batteries are the most used form of solar energy storage, but there are even other options to store electricity of your PV system. One of them is directing the electricity from your PV to water electrolysers, which generate hydrogen gas. Hydrogen is then stored and used as feedstock for fuel cells to generate electricity when needed.
What is energy storage & how does it work?
Sometimes energy storage is co-located with, or placed next to, a solar energy system, and sometimes the storage system stands alone, but in either configuration, it can help more effectively integrate solar into the energy landscape. What Is Energy Storage?
How can solar energy be stored?
The energy can be stored in batteries, where it is stored in the form of chemical energy for future use. For this purpose, efficient and safe charge controllers and solar energy storage management systems are used to ensure its availability when required.
Can solar energy be used as a energy storage system?
Existing compressed air energy storage systems often use the released air as part of a natural gas power cycle to produce electricity. Solar power can be used to create new fuels that can be combusted (burned) or consumed to provide energy, effectively storing the solar energy in the chemical bonds.
But next-generation batteries—including flow batteries and solid-state—are proving to have additional benefits, such as improved performance (like lasting longer between each charge) and safety, as well as potential cost savings..
