Technical FAQs 4

How can on-site solar PV & energy storage improve sustainability?

To achieve sustainability goals while meeting the increasing electricity demands of electrification, organizations are pairing on-site solar PV generation with on-site energy storage. These systems, which are considered as “behind-the-meter” (BTM) systems, allow facilities to maximize the benefits of on-site renewable generation.

How do offsite solar systems work?

Offsite solar systems can be managed through an offsite or “virtual” PPA (structured much like an onsite PPA), where the developer owns and operates the system and sells the energy to the purchaser at a fixed rate, often lower than the standard utility rate.

Can photocatalytic water splitting produce solar hydrogen?

As a result, it was estimated that photocatalysts capable of splitting water with STH values of 10% and lifetimes of 10 years can achieve economically viable solar hydrogen production via photocatalytic water splitting 1.

What are solar-to-chemical conversion processes based on water splitting?

In this context, solar-to-chemical conversion processes based on water splitting have been widely investigated 1, 5, 6, 7, 8, 9, 10. The hydrogen produced can be used as a fuel at different times and places and can also serve as a basic raw material in the chemical industry, including carbon and nitrogen fixation through catalytic processes.
