Compressed air energy storage

Eco-Tech Ceram (ETC) is a European Small Enterprise focused on the industrial energy efficiency market.  EcoStock, using refractory ceramic made from waste. This solution contributes to two of the European 2020 objectives: 20% reduction of greenhouse gas emissions and 20% reduction in primary energy use, by recovering and reusing their waste heat
 

The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

Northwestern researchers have developed the ability to store large-scale electrical energy for renewable energy sources such as wind and solar. Established energy storage technologies such as hydroelectric water pumping and underground compressed air storage are limited to specific geographic sites and most batteries and ultracapacitors have limited energy storage capacities and times.

Emefcy’s EBR for industrial wastewater treatment is based on three components new to biological wastewater treatment: - Anodes (in anaerobic conditions): Where the bacterial oxidation of the organic matter occurs - Cathodes (which are exposed to air): Where the corresponding reduction reaction takes place - An electrical circuit that includes the external load connecting the anodes to the cathodes. A biofilm naturally develops on the anode oxidizing the organic matter into carbon dioxide.

Glass sector is a major energy consuming sector. Gujarat ( India) is a hub of large scale Glass industries. Cleaner Production assessment was carried out in selected Glass industries of Gujarat with technical study of process, we streams etc. After study, Energy conservation, water conversation, solid waste and liquid waste reduction options were successfully implemented.

Specialising in solar, wind, and energy storage technologies, the PEC has worked in Africa, South America and Asia. PEC has over 100 wind turbine installations, over 500kW of solar photovoltaic installed (ongrid/offgrid), and over 1MW of hydrogen storage technologies designed, manufactured andinstalled globally. PEC has provided over 100 consultancies and their staffs are rapporteurs and energy experts for the EU commission.

The second generation of Compressed Air Energy Storage deals with the thermal issues to achieve higher efficiences. Currently, there are a number of companies and demonstration plants. Efficiencies between 70 and 80% are forecasted.

Applications: long term-storage, short-term storage, arbitrage, distributed/off-grid storage, frequency or voltage regulation, reserve grid capacity, mobility

Compressing air is a way to store energy, and combining this with a generator yields a way of storing electricity. Systems have been in use in applications such as starting large engines or in the propulsion of mine locomotives. At a larger scale, the technology is used to shift the energy demand for smaller and larger electricity grids, providing storage. Air heats up when compressed, and cools down when decompressed, generating a natural barrier for efficiency. To counter this, some installations use an external source of heat, like natural gas. Efficiencies up to 45% are attainable.

Wilefko wave is a novel system consisting of trains of oscillating blades with an intermediate stage of accumulation of compressed air with a threefold purpose: 1) generate electricity 2) seawater desalination and 3) pump water. It uses an energy source that is the ocean which is more constant abundant predictable and with a capacity of 800 times more energy than wind energy FEATURE 1. Multi-linear palette method increasing from 2 to 3 times the energy harvested 2.
