OVERVIEW

Compressed air in Steel-fabricated High Pressure Storage Cylinders

Energy storage capacity for the USA in 2030 is projected to reach 150x the level of 2019.  New technologies and investments will drive this industry over the next 10 years.  Our CLIENT is an energy storage start-up that has developed a technology using Compressed Air Energy Storage (CAES) aiming to store compressed air in steel-fabricated High-Pressure Storage Cylinders as its energy storage media for use with captured energy using solar or wind power.  

They needed a business partner to provide the scientific and cost evaluation, mechanical design and manufacturing expertise of these ASME storage vessels.

APPROACH

Design-Build engineering & fabrication per ASME standards

DIMARTECH provided the CLIENT with a project plan complete with design-build engineering and fabrication per ASME standards.  Operating at over 1000 psi, the vessel sizing efficiency is governed by shell thickness (thickness is directly proportional to both pressure x diameter).  The diameter was limited to 36’’ to prevent the shell material thickness from becoming prohibitive in manufacturability and cost.  An optimal total volume capacity was designed to determine the required number of cylinders for the closed-loop system.

DELIVERABLES

Complete system of ASME vessels in a modular format.

The total volume of vessels was calculated to over 10,000 cu.ft. and optimized for manufacturing parameters such as quantity of vessels, individual vessel sizes, shell plate thickness, length/diameter ratios, thermodynamic concepts for heat transfer and energy storage, and overall vessels footprint with on-site stacking.  Twenty different variations were evaluated, one was retained and presented to the CLIENT for their approval.

This design collaboration led to the successful fabrication of a complete system of ASME vessels in a modular format, ready for installation at a hydroelectric utilities company.  At the time of this writing, this project is still on-going and awaiting field installation.

This project also led DIMARTECH to develop an efficient manufacturing process for sizing and welding heavy wall steel cylinders with a Dual Submerged Arc Welding process for use on heavy wall piping and cylinders.  The Dual SAW setup effectively doubles the welding rate in the same time frame.
