Israel dream of solar thermal power generation

Polaris solar PV net news: in the Negev desert sun parched from Israel ancestor Jacob dreamed of ladder near the place, a huge solar-thermal power station is being built, the construction of the project will contribute to further development of solar-thermal power generation technology in the country and would help Israel achieve its 2020 renewable energy target set by.

This named Ashalim solar thermal power stations, with a total installed capacity of 250MW, a project now under construction Ashalim1 130MW. The project developer for the France industrial giant Alstom and United States solar thermal company BrightSource, it will become Israel’s largest solar power station and one of the world’s largest solar thermal power complex project. It can be said that the project in recent years, solar-thermal power industry compete with cheap photovoltaic industry one of the few bright spots in the process.

In the past two years, companies such as Areva, Siemens and ABB has quit the solar-thermal power generation market, only a few companies such as Alstom insisted. Alstom renewable energy project Vice President StevenMoss said: “the Ashalim has important meaning for the construction of the project. First of all, it is the map of solar-thermal power in a large project, it is important because it will further promote the development of solar-thermal power generation market. In addition, it will provide public utilities, banks and investors that the feasibility of solar-thermal power generation technology. Israel Government should be well aware that, under favorable conditions in the Sun, the future for a long period of large-scale solar thermal power generation projects will be on electricity pricing is very competitive. ”

Developed by Ashalim project adopted with BrightSource Ivanpah project size 392MW landmark similar solar-thermal power generation technology, Moss thought the LCOE of solar-thermal power generation costs from the current US $ 0.05~0.07 US $ 0.17 per cent in 2020 under the/KWh/KWh.

His forecast and Germany coincides a solar energy Research Institute in new studies, forecast in the coming 10-15 solar-thermal power generation costs will fall by at least 50%, in 2020 and between ~2030 cost of solar-thermal power could meet the criteria for traditional fossil fuel power generation.

Meanwhile, IEA (International Energy Agency) has also expressed similar views, IEA think that solar thermal power will be in the future play an important role in the global supply system, and predict that by 2050 solar-thermal power 11.3% of the world’s electricity needs will be provided.

Moss said: “by Ashalim and Ivanpah project construction and operation of the project, we are to demonstrate the reliability and effectiveness of Tower-type solar thermal solutions, and after adding mass storage system will greatly reduce the cost of electricity is feasible. Israel Government will understand that future solar-thermal power project can reference Ashalim project as a template for building solar-thermal power generation costs will also decline further. ”

But for many observers, above expectations and goals is too optimistic. SilviaMacri, a senior analyst of the international energy consultancy IHS that other construction of some high profile status of large solar thermal power station and shows no prospects for rapid development of solar-thermal power industry will, such as the investment of 600 million US dollars, Abu Dhabi Shams1 tank capacity of 100MW solar thermal power plant and Morocco 160MW Noor1 with total installed capacity of 500MW solar thermal projects.

SilviaMacri says: “Shams1 power station has been put into operation, but its cost is too high. In fact, so far, we have not seen more of the country plan to build solar thermal power project. Noor1 power station is currently advancing very well, but the essential thing is that involving many countries contributed to very low financing costs play a huge role in this project. In other places, many solar thermal projects have been canceled, solar-thermal power generation have received very few opportunities. While the solar-thermal technology in the provision of electricity has enormous potential for development, but we believe that in a short period compared to solar thermal technology and PV is not competitive enough to get more project opportunities. According to our projections, by 2030 Israel solar-thermal power installed capacity up to 400MW, this figure falls far short of many other forecasts. ”

But Moss acknowledged that energy storage system solution can significantly reduce the cost per kilowatt of solar-thermal power generation projects. For example, uses molten salt as the heat conducting medium of photo-thermal power station in the hours after the Sun can still generate electricity, can even be kept running around the clock. Moss do think it is important for photovoltaics and other renewable energy sources cannot match advantage.

But just like Ivanpah, Ashalim project does not have any storage system. They can only under good conditions of sunshine in the daytime power, also need to supplement natural gas generate electricity unit, gas generators for the power plant to run more flexible and adjustable.

This choice appears to be due to Israel recently in the Eastern Mediterranean coast picked up a large amount of natural gas resources, which will provide enough natural gas in 25 of the country’s fuel needs, also made Israel first become an energy exporter.

Moss believes that Ashalim solar-thermal power gas power generation accounted for annual energy output of project design 15% design 300GWh is a coincidence, this solar thermal power project with the General standard of provision was consistent.

Moss said: “the fact that Israel finds a new source of natural gas is not a solar thermal power plant using the auxiliary energy as a major reason, we do not believe that natural gas combustion can reach economy of configured storage system. Current solar-thermal project in the development of other places are almost always accompanied by the storage system, in addition to the technical route Ashalim and Ivanpah project. When understanding Israel’s specific situation, we’ll see. Because Israel now desperately wants to finish as soon as industrial-grade solar-thermal power generation project construction and put into operation, while the storage system is being considered in the second phase of the development of solar-thermal power generation. Natural gas combustion for Ashalim project means plants can be carried out after sunset to maximize the production of electrical energy, which can make the station quick start early in the morning or during the night can still run slow. ”

In addition, Ashalim more large-scale solar thermal project and future projects for Israel to complete its renewable energy goals, Israel planned by 2020 from renewable sources with a 10% power supply by 2050, which will reach more than 50%.

In order to finish the renewable energy targets, Israel released about Congress in 2011 large scale solar thermal power plants and photovoltaic power plant electricity price subsidies. But the implementation of this policy because of the bitter conflict between the two factions in Congress and was discontinued, and charged in the first batch of projects to support payments policy will no longer be implemented.

Then Israel will these savings the Government subsidy funds to the installed capacity of 300MW PV on the project tender, which is located in Israel near Eilat in the South, installed capacity of 50MW Timna project is remarkable. Israel development of solar-thermal power generation even more unfavourable factor is the Israel Government is now moving indicator light from heat and wind power production to large scale photovoltaic power plant and plans to achieve PV installed capacity doubled by 2016.

Israel Eilat-Eilot of renewable energy schemes implementing body responsible for Timna project bidding, its Chief DoritDavidowski-Banet said: “we have no new preferential policies to support the development of new renewable energy projects, we have targets for renewable energy development. By 2020 renewable energy generation reached 10% per cent of the target was too difficult to implement, I think it slows can be achieved has been quite good, and it takes into account the newly discovered gas resources and production factors. Another reason is that we are in the area of solar thermal power generation of feed-in tariff preferential policies be cancelled and be adjusted to scale up to 300MW of installed PV projects US $ 0.08 per kilowatt subsidy, and like the rest of the world, Israel will PV as a first choice. While solar-thermal power can be very stable power throughout, but it is clear that the Government has been startled by the per unit cost of us $ 0.15~0.2 is up. ”

Davidowski-Banet believe that natural gas can provide Israel electric production support 20-25. But she predicted that during this period of time, with thermal energy storage system for solar-thermal power generation technologies, pumped storage technologies and other innovative technologies will slowly become the main power generation technology. She said: “I believe 300MW project subsidies once it ends, the Government will find the solar market competition will become more intense, photovoltaic power generation in the short term may have the advantage, but solar-thermal power generation will quickly catch up. I’m very confident about it, I think the solar thermal power industry have rebounded from the lowest, it will reach new heights. ”

Alstom was similarly optimistic.

Moss said: “accompanied by Ashalim progress and abenge companies involved (120MW Ashalim2 near abenge company in Ashalim1 project trough solar thermal power generation projects will soon be building), solar-thermal power wheels began to function properly and progressive track. Every step he took away from us we now to 2020, solar-thermal power generation costs are reduced to us $ 0.05~0.07/one step closer to that goal. In market competition with PV, DNI conditions we can see in some areas, large-scale solar-thermal power project is adjustable in its stable and available power advantage gradually prevailed. We hope to photothermal Alstom’s attention and we have technical experience in solar thermal power generation combined with regional advantages, solar-thermal power generation gradually become United States, and Israel, the Middle East and South Africa the mainstream technology for solar-thermal power generation to grow to global electricity production systems in the real team. This goal is our biggest motivation now. ”
