Zambia energy and chemical group air compression energy storage

What is compressed air energy storage (CAES)?

Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.

Why should German and European service providers invest in Zambia?

For German and European service providers active in the energy sector, Zambia presents significant potential for business development. There are clear needs across the solar energy and storage value chain, including pro-ject development and financing, equipment manufacturing, system inte-gration and contracting.

What is a conventional compressed air energy storage system?

Schematic of a generic conventional compressed air energy storage (CAES) system. The prospects for the conventional CAES technology are poor in low-carbon grids [2,6–8]. Fossil fuel (typically natural gas) combustion is needed to provide heat to prevent freezing of the moisture present in the expanding air .

Can a small compressed air energy storage system integrate with a renewable power plant?

Assessment of design and operating parameters for a small compressed air energy storage system integrated with a stand-alone renewable power plant. Journal of Energy Storage 4, 135-144. energy storage technology cost and performance asse ssment. Energy, 2020. (2019). Inter-seasonal compressed-air energy storage using saline aquifers.

Can battery storage be used with solar photovoltaics in Zambia?

The Zambian regulation foresees customs duty and VAT exemptions for most equipment used in renewable energy or battery storage projects. Detailed information is provided in In this section, we discuss the opportunity of battery storage in combination with solar photovoltaics from a financial point of view.

How do compressed air storage systems use energy?

The modeled compressed air storage systems use both electrical energy (to compress air and possibly to generate hydrogen) and heating energy provided by natural gas (only conventional CAES). We use three metrics to compare their energy use: heat rate, work ratio, and roundtrip exergy efficiency (storage efficiency).
