This week in Ukrenergo Review you will learn about the generation of electricity from municipal waste.
As well as testing by the Swedish energy technology company on the basis of salt storage technology for storing electricity, how smart homes can generate electricity and much more.
- Poland will generate electricity from municipal waste
The heat suppling company of the city of Olsztyn (Poland) is implementing a project that will become the main source of heat for district heating of the city. The project also envisages the production of electricity, and decided to use municipal waste as energy resources.
The European Commission has allocated €54 million in financial assistance for the construction of a corresponding high-efficiency cogeneration electric power plant. The assistance is provided in the framework of the implementation of the EU energy and environmental policy and will contribute to the achievement of the stated objectives in these sectors. In particular, cogeneration increases the efficiency of using the energy resources by utilizing heat energy from electricity generation for other needs, such as district heating. The new installation will also help reduce the amount of waste currently in urban landfills, burning around 100,000 tons of garbage that are currently buried.
The project is planned to be implemented in the framework of public-private partnership between the Olsztyn thermal power plant and a private company that will be chosen through a competitive procedure.
- The Swedish power company is testing the storage technology based on salt for storing electricity
The Swedish power company Vattenfall has launched a pilot project that will explore the possibility of using salt for accumulators for the accumulation and storage of electricity, reports Energy Live News.
Vattenfall is working with Swedish company SaltX Technology that is owner of the respective technology. This technology allows you to charge the “salt battery” several thousand times and provide storage without losses for several weeks or months.
Developers also claim that technology allows to store up to 10 times more energy compared with conventional water-based batteries.
The technology will be tested on an industrial scale for the first time at Vattenfall’s thermal power plant in Berlin. Electric power plant will be taken out of service next year as part of the company’s plan to completely phase out coal as a fuel by 2030.
Project managers say that they will collect data about the profitability of this type of plant in their business over the next few months. In particular, focusing on such questions as the required amount of salt, the speed of the reaction of the conductor in the computing battery, and the ability to control of this process.
- Smart homes can generate 130% more power than they need
The American Foundation for Sustainable Energy plans to move to a new smart office. The new building will generate 130% more energy than it needs, challenging conventional thinking about energy efficiency in the commercial sector. The building will consume about 25% of the energy used in buildings of this type.
The order performer, design bureau Ashley McGraw Architects, in his project uses several design and technology strategies, including:
– The building will be oriented on its site—within an existing apple orchard—to take maximum advantage of sun and shade, with its surfaces and openings precisely positioned to minimize energy expenditures
– An array of photovoltaic panels mounted on the roof of the single-story building will generate all necessary energy for the operation of the facility
– The design of the building is made with effective thermal insulation and close attention to tightness;
– All building systems—from ventilation and air conditioning to electrical and lighting equipment—are selected and engineered with the highest indicators of energy efficiency.
According to the President and CEO of the Foundation, John Costlow, the project demonstrates the commercial viability of smart buildings, as well as the ability to build a smart home for the same costs as the construction of a conventional office building.
- Portable wind turbine will allow to charge the mobile devices away from the gird
Smartphones can now be charged from wind power. The British start-up project have created a new portable wind turbine capable of charging a smartphone, camera, or tablet, regardless of the electrical grid, the Geeky Gadgets reports.
The device has a waterproof and shock resistant body that protects it from rain and makes it resistant to damage during transportation. The amount of electricity generated by the device depends on the wind speed. However, in the technical characteristics of the wind turbine it is indicated up to 1A current strength, which is transmitted to the device, which should be charged, using a USB cable.
The device is currently in the test phase, but it is expected that it will go on sale in June 2019.
- Artificial intelligence can reduce greenhouse gas emissions by 4%
Using artificial intelligence can help to reduce greenhouse gas emissions in 2030 by 4%. That’s the verdict from PwC UK, which highlights this would total an amount equivalent to 2.4 gigatonnes of carbon dioxide, comparable to the 2030 annual emissions of Australia, Canada and Japan combined, according to Energy Live News.
The consulting company сlaims that using artificial intelligence in the agriculture, water, energy and transport sectors could reduce the impact on the environment by optimising energy use and creating new business models.
In the report notes that artificial intelligence could have the biggest emissions impact in the energy and transport industries by enabling a reduction in energy use and automating manual and routine tasks, which in combination could lower energy emissions per unit of GDP by up to 8% in 2030.
The company analysts also find that artificial intelligence technologies could improve health, suggesting that more accurate and localised early warning systems for air pollution could save an estimated $2.4 billion (£1.8bn) in reduced medical costs. Analysts also add that using artificial intelligence would be necessary for sustainable and economy.
