CAES Mechanical Wind Energy Storage


The construction and testing of a modular, low pressure compressed air energy storage (CAES) system is presented. The low pressure assumption (5 bar max) facilitates the use of isentropic relations to describe the system behavior, and practically eliminates the need for heat removal considerations necessary in higher pressure systems to offset the temperature rise. The maximum overall system efficiency is around 97.6%, while the system physical footprint is less than 0.6 m3 (small storage room). This provides a great option for storage in remote locations that operate on wind energy to benefit from a nonconventional storage system. The overall size and capacity of the system can be changed by changing the number of active cylinders, which in this case are off-the-shelf, small pressure vessels used for fire protection. Moreover, the system operation is automated and capable of addressing both high energy and high power density applications with an infinite number of charge-discharge cycles by augmenting the capacity with the required number of storage cylinders. The system is eco-friendly and has low maintenance costs compared to chemical storage.

United Emirates Habshan-Fujairah pipeline

The United Arab Emirates is nearing completion of a pipeline (236 miles/380 km) through the mountainous sheikdom that will allow it to reroute the bulk of its oil exports around the Strait of Hormuz at the mouth of the Gulf, the path for a fifth of the world’s oil supply… Once it’s running at full volume, the pipeline will let the UAE get two-thirds of its peak oil production to market even if the strait is shut. That’s about 10 percent of the total 17 million barrels of oil a day that currently goes through Hormuz. The pipeline is expected ready to be used later this month. The pipeline is 4 foot wide and designed to handle 1.5/1.8 million barrels of crude a day. The pipeline was constrcuted by China National Petroleum Corp.

UAE abandoning US$ in China trade

[UAE Palm Island][source]
The US dollar is fast losing out its reserve currency status with China aggressively replacing the dollar with the Yuan as a currency for bi-lateral trade. The latest is an agreement signed between the China and the United Arab Emirates (UAE), which will use the Yuan for oil trade.
