[ RadSafe ] Another recent article

Dr. Brennan,

Do you have a reference for the liquid nitrogen technology?

Respectfully,
Stan Morton

One of the slickest energy storage systems I've seen involves liquefying nitrogen.  The tech is mature and well understood, the energy density compares with batteries, and it has useful byproducts (filtering the air, producing compressed oxygen, etc).  It is also pretty safe, compared to a lot of other energy sources (a leak puts out fires, rather than feeds them).  It is not, however, flashy, and so isn't receiving much attention).

It appears that the peak energy storage conundrum isn't unique to Solar photovoltaic energy production.

Wind Power May Not Reduce Carbon Emissions As Expected: Argonne "Argonne researchers are working on one possible solution to this problem: 
batteries that can store wind power for use when the wind stops blowing—as well as store solar energy for use at night". Roy Herren

Solar thermal at least has some built-in storage capacity. One would think that that would play some role.
