Electric power Norway

The wodd s total capacity of grid-coimected electric power derived from wave energy is less than half a megawatt, distributed among several demonstration plants. The largest unit, the 350-kWe Tapered Channel plant in Norway, uses the hydropower approach. The plant was developed by Norwave AS and has operated continuously since 1986. Based on this durabiUty, two commercial orders were placed from other parts of the wodd. 

Electrolysis continued to be used for primary enrichment in countries with abundant electric power, such as Iceland and Norway, where the H2 is used in ammonia manufacture [9]. Molecular deuterium, D2, is produced in Norway by the electrolysis of DzO. For heavy water production, the method has, for the most part, been replaced by steam-H2S exchange columns for heavy water enrichment ... 

The fixed percentages of natural gas and coal inputs would in practice be modified for countries with resources primarily of one type. For example, Norway and Saudi Arabia would increase their use of natural gas in order not to have to import coal. For covmtries able to cover their own electricity requirements with existing hydro, e.g., Canada and Norway, the scenario construction does not initially take into account export options, and the hydro input in Fig. 5.33 is therefore less than the potential production (by 177 GW). This additional capacity will in reahty be used for export of electric power to neighbouring covmtries and thus will slightly diminish the use of fossil fuels, on a global level. 

In cases where electricity is expensive, materials maybe shipped great distances for cheaper electricity sources. For example, large amounts of aluminum were reduced using cheap electricity in Norway, due to Norway s very large fjords and cascades that produce cheap power in large hydroelectric plants. 

For electrical power generation based on an integrated concept, the efficiency can be as high as 25-30 %, comparing the power supply to the furnace with the power generated in the steam turbine. In addition to electrical power generation, a possible efficiency of around 100 % has been attained for production of process steam or district heating. Several ferrosilicon plants in Norway (six) and... 

The number did not increase until after 1906 as shown in Table 10.1. That was when hydroelectric power plants started to be built in Norway in larger numbers. The power was cheap and had to be used locally. That stimulated the construction of chemical plants for producing calcium nitrate (Norwegian saltpetre) using a new process developed by the professor of physics Kristian Birkeland and the construction engineer and industrialist Sam Eyde. Also other processes were developed later depending on cheap electric power and requiring chemical expertise. 

When cheap hydroelectricity is available (e.g., in Canada and Norway), the smelting of ilmenite is the preferred option for ilmenites containing less than 58 wt.% TiO, while at higher electric power costs the range of ilmenite for which smelting is preferred is much narrower, up to 52 wt.% TiO,. ...

The concentration of nitric oxide in the effluent gas produced by this process was only 2%. The energy consumption was enormous and, consequently, the process could only be viable in countries where cheap electric power was available. This is the reason why the first plant was operated in Notodden, Norway, in 1904, using hydroelectricity. 

In Norway and Romania, hydrogen production and export is in direct competition with electricity transmission via high-voltage direct-current lines (HVDC). This solution is particularly attractive because hydropower is a non-fluctuating renewable energy source and does not destabilise the grid, as, for example, wind or solar power do. 

The water in rivers and streams can be captured and turned into hydropower (HP), also called hydroelectric power. HP currently provides about 17% of the world s electricity supply, virtually all of Norway s electricity and more than 40% of the electricity nsed in developing countries. However, there is great potential in hydropower worldwide. Norway produces more than 99% of its electricity with hydropower. New Zealand nses hydropower for 75% of its electricity. HP provides more than 97% of all electricity generated by renewable sources. Other sources, biomass, geothermal, solar and wind account for less than 3% of renewable electricity production. When the electricity share of total energy consumption is considered, the increase becomes even more dramatic. 

Promising news for tidal power is coming from a radical design—a tidal mill that looks a lot like a land-based windmill. The tidal mill consists of three 30-foot long blades and weighs 180 tons. This design can offer several benefits, including minimal interference with sea life. Hammerfest Stroem, the electric company in Hammerfest, Norway, has... 

Measurements of SO in Southern Norway diving the months of May, June and July (Clark, P.A., Central Electricity Research Laboratories, personal communication) indicate that it is reasonable to consider that on average, polluted air leaving the East Coast of England and Scotland derives from emissions from one large conurbation and one 2000 MW power station. The consequence of above-average levels of pollution are also investigated. 

The components making the autonomous system were integrated electrically at 400 V (TN-S) 50 Hz. A separate 315-kVA, 22/0.4-kV transformer connected a 1.5 km cable, transmitting power from the autonomous system to the customer substation. All the 10 households were connected to the customer substation at 230V, which is the standard voltage level in Norway. The customer substation also...
