Alternative Energy Technologies provide “low carbon” alternatives to fossil fuels. All can contribute to reducing CO2. No single technology predominates in the UK but all play a part in meeting the future demand or displacing other equipment that is more “energy intensive” when it comes to the end of its commercial life.
Wave & Tidal
Tidal Power arises from the gravitational pull of the sun and moon causing water levels to change. This change in level creates currents from which energy can be harvested by the use of sub-surface turbines. A tidal turbine can produce more than X4 the energy per square metre of a wind turbine.
Manufacture of wind turbines on a commercial scale started in the 1980s. It is currently the fastest growing sector of the power generation industry, with anticipated industry expansion rates consistently being exceeded since the early 1990s.
Of the available technologies, biomass firing has a high priority because of the modest technological risk involved and the ready availability of waste biomass in many countries. Biomass fuel can be supplied from a variety of sources, and in a variety of forms. Sources include waste biomass, either from agriculture / forestry operations (e.g. wheat straw) or from the green element of municipal or industrial waste from farmed biomass, “energy crops” from land-based agriculture or from the sea. Biomass from the sea (seaweed) avoids competition with food production for land and fresh water, but contains very high levels of contaminants restricting options for use.
Often sources of Alternative Energy promote operation in severe environments. Monitor contributes to the Alternative Energy Technology development programme by offering complementary coatings which extend the life of operating equipment functioning in such environments.
