In modern times, large quantities of ...

How giant ''water batteries'' could make green power reliable

Pumped storage might be superseded by flow batteries, which use liquid electrolytes in large tanks, or by novel battery chemistries such as iron-air, or by thermal storage in molten salt or hot rocks. Some of these schemes may turn out to be cheaper and more flexible. A few even rely, as pumped storage does, on gravity.

How does CCUS work? A CCUS application consists of three stages: capture, transport and storage (or usage) of CO 2. The main methods for capturing CO 2 are: post-combustion; pre-combustion; and oxy-fuel combustion. Post-combustion technology separates CO 2 from the flue gas, by using a chemical solvent for instance, after the fuel is burnt.

Why are H+ ions pumped out instead of in during cellular …

I was wondering, however, why the H+ ions are pumped out of the matrix or cytoplasm, instead of into it. For aerobic prokaryotes, and the early mitochondria (which were prokaryotes living on their own) pumping the H+ ions out of the matrix or cytoplasm means pumping them into the outside world, a very uncontrolled environment.
