~ Study Energy Efficiency And Renewable Energy

World's technical experts are to help harness wave and tidal energy

the SMB set up a strategy group to study Energy Efficiency and Renewable Energies. In the May edition of TC News we reported that SMB (Standardization Management Board) were to decide on how to deal with renewable energy activities in the IEC.

At the June SMB meeting a presentation was given by Dr. Gouri Bhuyan, Chairman of the   Executive Committee, whose present programme focuses on ocean waves and marine currents.

The decision taken by the SMB at that meeting was to set up an entirely new committee, TC 114, Marine Energy – Wave and Tidal Energy Converters, to develop International Standards for wave and tidal energy technology that will help establish this promising source of renewable energy as a competitive form of electrical energy production.

The creation of this new technical committee dealing specifically with the area of renewable energies (RE), follows those already working on water, sun and wind, namely  Hydraulic turbines, , Solar photovoltaic energy systems,  Wind turbines and, as an efficient alternative form of energy to work in parallel with RE,  Fuel cell technologies.

According to the 2006  published by the  world production of electricity is expected to double over the next quarter-century and renewable energy production to increase by 57%. Indeed, to reduce the dependence on fossil fuels, mitigate the effects of global warming, and to raise the living standard of people in developed and developing countries it is important be able to adopt a large scale use of renewable energy.

The report issued by the  Germany stated that: "Accelerated deployment of renewables can significantly reduce CO2 emissions, enhance energy security and further reduce technology costs."

Much of renewable energy is an emerging field of research, technology and manufacturing and a new industry is growing up. The IEC will help to ensure that, as the technologies mature, the International Standards will help to bring down technology costs to make renewable energy increasingly competitive with existing energy alternatives, while ensuring the transfer of expertise from traditional energy systems.

Standards that will be developed by the new grouping of experts will cover the performance of tidal and wave energy converters, how these converters will plug into electricity grid systems, and how they should be tested.

Tidal or ocean energy devices are either floating or fixed and, to generate electrical energy, they tend either to oscillate or to rotate. Research on this technology started in Japan in the 1940s. While there has been limited use since the 1970s, functioning units have been in use in various countries since the 1990s, mostly as prototypes.

National Committees now have until August to let the SMB know that they intend to participate actively as P-members (participating) in the new TC.

As part of the IEC's activities in monitoring work in the area of energy efficiency and renewable energies, technical committee and subcommittee officers will shortly receive a questionnaire designed to allow the IEC to create a full inventory of its activities in these areas. Whilst some the work of some TC and SCs is relatively easy to identify, there are many TC/SCs which may have less obvious work in progress, (for example, the materials used to manufacture cables has a considerable influence on energy efficiency). The results of the questionnaire will be used to identify areas which are not currently being covered by the IEC. All TC and SC officers are strongly encouraged to return the questionnaire.
