TERRAJOULE
Cost Breakthroughs
THE GAME CHANGER
Critical breakthrough in energy storage costs
-
Radically less expensive, simpler, and more durable than batteries
-
No new, rare or toxic materials - just steel pressure vessels and water
-
Fact: the heat capacity
of water is ~3x molten
salt, ~5x concrete,
~8x iron
a simple energy storage breakthrough
-
steam piston engine has a much wider input pressure range for efficient operation than a turbine
-
multiplies the SAES energy storage capacity at no additional cost
-
follows rapidly varying loads using valve timing, with no inefficient steam throttling loss
steam accumulator energy storage (SAES)



CRITICAL COST FACTOR
Reduced pressure vessel cost
By exploiting a low-cost technology brought to scale for natural gas pipelines
-
Submerged spiral arc welding (SSAW) is a significant evolution reducing pressure vessel cost
-
The equipment was perfected by industry in response to the demand surge in high-pressure gas pipelines driven by fracking
PSC
Prefabricated solar concentrator
-
End-to-end design for automation,
factory ⇒ shipping ⇒ onsite installation ⇒ maintenance -
3:1 installed cost reduction vs. prior industry solar concentrators
-
10:1 reduction of installation labor hours, greatly reduced construction time
-
Classic Linear Fresnel format ⇒ nothing new in functional principles, just designed for prefabrication and automated installation


PSC Segment
OVERCOME LIMITATIONS OF
Solar concentrator design
-
For conventional CSP, wind load necessitates heavy, expensive structures and foundations
⇒ Terrajoule PSC’s compact no-gap format reduces the wind load and material per square metre, and increases land use efficiency
-
Conventional CSP is limited by high labour hours and long construction times
⇒ Terrajoule PSC’s compact format enables factory prefabrication and pre-assembly of components that ship in standard shipping containers
⇒ end-to-end design for automation carries through automated installation onsite, reducing labor 10:1
