Potential of Wine and Pumped Storage for Energy Security

Potential of Wine and pump warehousing for nada SecurityIntroduction might security is making convinced(predicate) there is enough electrical supply for demand based on a price which is not too volatile. In order to make real of the readiness security for the time to come governments around the world atomic number 18 introducing unexampled plans to reform their current strategies. In the UK it has an Electricity Market Reform which is said to rip 100 billion GBP. (DECC, 2016a) Increasing energy efficiencies, maintaining reliable networks, and increasing connectedness of nearby countries will all lead the way to making sure we are sufficient for the future. Commitments from governmental commitments pass on strengthen this resolve for object lesson the EU renewable energy directive of 15% energy consumption of 20% by 2020. locomote EnergyThis form of renewable energy uses the f pathetic of air from the tinge to rotate a turbine which generates electrical energy. The equation to calculate the power through a square metre is given below which in turns shows that the power is proportional to the velocity of the wind and as shown by Coley (2008) as you increase in top side above land the faster the wind speed is which is why wind turbines are increasing in sizeFrom DUKES (2016), it states a total electrical coevals from Wind in 2015 for the UK was 83550 GWh as which Wind contri only ifed to 18965 GWh (18.965 TWh). The total wind generation has increased by 26% from 2014 to 2015.DECC (2013) are predicting an annual growth rate of 13% for onshore wind over the next decade with 11 GW electrical subject matter currently under or awaiting construction and in planning phase. For offshore up to 18 GW could be available by 2020.Figure 1 UK coverage of wind turbines (RenewableMap, 2016)Wind can be predicted with a margin of error but is difficult to store so other technologies are needed to compensate it.Pumped entrepot hydroelectricity (PSH)This renewable sou rce stores energy in the form of gravitational potential energy of water with two reservoirs. During high demand water from the top reservoir is released and goes through a turbine which generates electricity. The top reservoir is recharged during times of low demand. It can be used to reduce the amount of start-ups and shutdowns and maintain a steady balance between supply and demand.Pumped shop hydro is the roughly whippy source of power generation available, it can meet demand within minutes.The main countries with the highest wield storage capacity are Europe, Japan, and the US. The total pumped hydro capacity worldwide was 136 GW in 2010 compared to 98 GW in 2005. The installed small hydro was 61 GW in 2010. (genus Irena, 2012) jibe to Owens (2013), there are around 50 pumped storage hydro sets that subscribe a capacity of 1GW. The worlds largest is Bath County Pumped Storage Station which has a capacity of 2.7 GW.Unlike a dam a PSH has little damage to an ecosystem in co mparison. The flooded area would be best suited in a low organic content area.Figure 2 Example picture of PSHAccording to DUKES (2016), the total electrical generation from hydro in 2015 for the UK was 6.3 TWh. 7.5% of the renewable generation was from large outperform hydro.Figure 3 UK coverage of hydro projects (RenewableMap, 2016)PSH is one of the few large scale renewable sources which gives an affordable means for storing while generating low cost electricity carbon-free. It has the ability to generate electricity based on demand instantaneously.23 GW of PSH capacity is undergoing construction with 8.3 GW announced for the future in the UK. (Scottish Renewables ,2016)In the US there are currently 40 PHS plants in operations totalling a capacity of 22 GW which accounts for 95% of all the energy storage in the country. 50 more(prenominal) PSH projects boast been proposed which could increase the total capacity by 40 GW. (U.S Department of Energy, 2015) ball-shaped Energy Stora geDifferent storage systems have been used in other countries like pumped hydro energy storage (PHES), thermal, battery, and hydrogen storage. Pumped storage has been found to be the leader due to its high capacity, flexibility, and availability. (Al Zohbi, et al., 2015)Scottish Renewables (2016) shows that 97% of world storage capacity is from PSH.Figure 4 Installed global capacity of energy storage (Scottish Renewables, 2016)Wind and Pumped Storage CombinationThe are several other methods of which can be combined with wind energy (e.g. hydro, conventional thermal, gas). Pumped storage has the advantage of always having available power even during dry period. (Montero Prez, 2009)Figure 5 Hybrid wind and pumped storage plant (Anagnostopoulos Papantonis, 2007)Example 1According to Ingram (2016), Germany are currently undergoing a pilot project for wind and pumped storage hydro. There will be quaternary wind turbines installed and a 16 MW pumped storage unit on the Kocher river. Th is will give a fast response to the grid and reduce cost of electricity for the consumer. The 4 wind turbines will be commissioned by the end of 2017 and the PSH plant will be operational by 2018.Figure 6 Pilot project combining wind and pumped storage hydro in Gaildorf, Germany (Ingram, 2016)Example 2A pumped storage system composed of 4 turbines and a 11MW wind farm has been built in one of the Canary Islands which will meet 80% of electrical demand. (Al Zohbi, et al., 2015)Figure 7 Pumped Storage Plant (Montero Prez, 2009)Example 3The concept of a 10MW wind farm installed in the Faroe Islands combined with a pumped storage plant. The reservoirs will be connected at Miovatn (upper reservoir) and Vatnsnes (lower reservoir) which could give a capacity of 10MW. The cost of the storage plant is estimated to be 5.7 NOK/kWh. (Nordon Energy Research, 2013)Figure 8 Catchment area in the Faroe Islands. (Nordon Energy Research, 2013)IRENA (2015) shows an increase in both Wind and Pumped Hy dro capacity by 2030 compared to 2013Figure 9 Total installed renewable capacity between stratum 2013 and 2030. (IRENA, 2014)A disadvantage with PSH is it is very capital intensive with long development and construction times. The main contributors being the infrastructure of the hydro plant and second to this is the electro-mechanical equipment. According to IRENA (2012), the total installed cost ranges from $1000 $3500/kW. This may also increase by an additional $3500/kW due to the cost of connecting to existing transmission networks this depends from location to location.Energy InterconnectednessAn electrical system which can become more flexible could save the UK consumers billions per year. Flexibility can come from interconnection of other electrical systems, for example wind and pumped storage hydro (PSH).The European Commission has set a target of 10% electricity interconnection for 2020. They are building towards a more integrated, competitive and sustainable common energ y market. They have put forward a European Energy Programme for Recovery (EEPR) mainly because of the economic crisis and with this have identified interconnection projects across the EU and to date spent 650 million EUR. (EuropeanCommission, 2015)The UK currently has an interconnector capacity of 4GW with France, Netherlands, Northern Ireland, and the Republic of Ireland. (Ofgem, 2016) According to Becker (2015), there is a further 7.3 GW proposed interconnector capacity from for example Belgium, Denmark, and Norway.The German Advisory Council requires 42 GW transmission capacity between Norway and Germany by 2050 to make PSH able to balance renewable electrical generation in Germany. Germany has a goal of 80% renewable electricity by 2050. (Ingebretsen Johansen, 2014).Norway possesses 50% of the reservoir capacity in Europe. Norway provides 98% of its electricity from hydroelectric plants. pock (2015) says that Norway could be a potential Green Battery for the EU but is restrict ed due to political and social issues. However, it has been announced that a 1.4 MW 740 km affiliate will join UK and Norway costing $1.64 billion which will be operational in 2021.The Global Energy Interconnection Development and Co-operation Organization (GEIDO) is a Chinese group with a goal of an Asian super grid by 2050. There are now agreements between energy companies in China, Russia, Japan, and South Korea. They have highlighted geopolitics as a main obstacle for grid interconnected stability and assumed that there will be access to the newly developing ultra-high potency lines which operates at 1000kV AC and 800 kV DC over 1000kms. (New Atlas, 2016)Figure 10 Global Energy Interconnection (GEIDO, 2016)A disadvantage of interconnectedness between countries is shown in Andrews (2015). During the summer time our demand is assured however during winter time when electricity demand is at its highest there is a potential for other countries to pay off the supply leaving anothe r without electricity (such as brownouts, blackouts, and overloads).ConclusionsWind and PSH will prove to be a necessity for providing energy security in the future. Wind is given an added benefit when combined with PSH of increased electricity usage by transferring energy at times of low demand. PSH is a mature and proven engineering science and gives the ability of supplying electric on demand within minutes.The future of energy security also relies on the interconnectedness of nearby countries connecting to Norway is seen as the most beneficially for supply of renewable electricity in the EU. However, on a global scale the geopolitical and social aspects between countries could be deemed as knotty and will need to develop if interconnector capacity between countries is to prosper.AppendixFigure 11 European Wind Atlas, onshore (EWEA, 2009)Table 1 Technical wind energy potential in the EU (Dursun Alboyaci, 2010)Table 2 Worldwide hydroelectric storage potentials (Dursun Alboyaci , 2010)1600 wordsReferences AL ZOHBI, G. et al.
