Ocean storage via pipeline. Ocean storage via tanker. For each option, the CO 2 source is a nominal 500 MWe gross Integrated Gasification Combined Cycle (IGCC) plant, operating at an 80 percent capacity factor. This plant delivers 7,389 tonnes of CO 2 per day. Given this source of CO 2, a baseline conceptual design was generated for each option.

READ MOREThe random nature of wind energy is an important reason for the low energy utilization rate of wind farms. The use of a compressed air energy storage system (CAES) can help reduce the random characteristics of wind power generation while also increasing the utilization rate of wind energy. However, the unreasonable capacity
READ MOREWe observe that economic incentives for houses to store energy depend deeply on the implemented pricing mechanism and on the homogeneity in the houses'' characteristics. Furthermore, when prices are based on the consumption of the eco-neighborhood, storage appears as a compensation for the errors made by the service

READ MOREWith certain caveats, energy storage paired with solar is eligible for the federal Investment Tax Credit (ITC), according to IRS Private Letter Ruling 121432-12. First, the systems have to be installed at the same time. Second, at least 75% of the electricity used to charge must come from the solar system.
READ MOREIt is shown that the LCOS decreases up to 28.8% when decreasing the discount rate from 8% to 6%. Whereas a discount rate of 4% results in a decrease of up to 47.5% reduction in the LCOS of the investigated systems. For example, The LCOS for Gravity Storage would fall from 111 US$/MWh to 87 and 66 US$/MWh.
