Clean energy generation

Fuel cells are developed as a viable alternative for clean energy generation. The rational operation of the fuel cell units is closely related to the development of very active, selective, and poison-resistant catalysts. 

The oxygen reduction reaction (ORR) is the primary electrochemical reaction occurring at the cathode of a PEMFC, and is central to this promising technology for efficient and clean energy generation. The ORR is a multi-electron reaction that follows the direct four-electron mechanism on platinum-based electro-catalysts. It appears to occur in two pathways in acid electrolytes (Adzic and Lima, 2009) ... 

You can also make oxygen by electrolysis of water into its component parts, O2 and Hg. These gases can be stored and then recombined again in a controlled way to produce power, with water as the only waste product. This forms the basis of hydrogen-powered engines and fuel cells, and is one of the big hopes for clean energy generation in the next few decades. 

The ability of consumers to voluntarily pay a premium to purchase environmentally preferred electric generation would seem to be a happy middle ground between free-market energy proponents and clean energy advocates. Yet, on closer inspection there are... 

Why Do We Need to Know This Material The topics described in this chapter may one day unlock a virtually inexhaustible supply of clean energy supplied daily by the Sun. The key is electrochemistry, the study of the interaction of electricity and chemical reactions. The transfer of electrons from one species to another is one of the fundamental processes underlying life, photosynthesis, fuel cells, and the refining of metals. An understanding of how electrons are transferred helps us to design ways to use chemical reactions to generate electricity and to use electricity to bring about chemical reactions. Electrochemical measurements also allow us to determine the values of thermodynamic quantities. 

An important task will be to develop a more efficient and clean use of fossil fuels -petroleum, natural gas, and coal and the generation of alternative clean energy resources. 

Hydropower A Study for the Generation, InterContinental Transport, and Use of Hydrogen as a Source of Clean Energy, on the Basis of Large-scale and Cheap Hydro-Electricity (Hydrogen Pilot Project - Canada) (DECHEMA, 1987)... 

Plug Power, Inc, of Latham, NY manufactured six alpha fuel cells to be field tested as part of the Clean Energy Initiative, the Long Island Power Authority (LIPA), Uniondale, NY. Hofstra University was the site of the first tests, which began in February 2000. By the 60-day mark, the fuel cells had generated approximately 1900 kWh and operated in parallel with LIPA s T D system. 

As a clean energy source, hydrogen gas (H ) has potential if used in an electricity generating fuel cell (Caglar, 2003). Hj production by reforming of HC-based fuels in suitable fuel processors has become more and more important, in particular for both mobile and residential fuel cells applications (Specchia et al., 2005). 

CLEAN ENERGY FROM BIOMASS - The project is addressed at demonstrating the industrial feasibility of the integration of biomass steam gasification with a MCFC for clean and renewable power generation. 

This motion generates energy. Attempts are being made to harness the energy of the waves and ocean tides. Tidal energy is an alternative source of clean energy.
