The renewable energy sources are again the top spot of the world energy news this week. And in order not to break our traditions, we offer you a selection of the most interesting energy news from around the world in our #UkrenergoReview.
- Eurelectric proposes to handle greenhouse gas emissions by electrification
Eurelectric proposes to electrify 60% of the EU economy by 2050 in order to achieve a 95% reduction in greenhouse gas emissions compared to 1990, according to its “Ways to Reduce Carbon Dioxide” report.
To achieve this goal, annual investments of € 89-111 billion are needed for the development of renewable energy sources and the EU infrastructure while ensuring high demand for electricity.
The growing share of renewable energy in the overall generation of the EU will require increased flexibility of the grid, the development of interconnections, amplification and digitization of distribution networks, as well as increasing the quantity and capacity of power storage systems to meet demand.
Francesco Strassace, president of Eurelectric and CEO of the Enel energy company, said renewable energy is becoming more cost-effective, technologically simpler and therefore plays a key role in the production and transmission of energy.
Transformation requires changes in the energy compatibility of the energy sector, through the introduction of anticipated regulatory changes and the adoption of long-term pricing policies to attract private capital.
- RWE coal mines will be closed in favor of solar and wind power plants
Greenpeace Energy wants to close the coal mines and power stations of the German RWE company by 2025 and replace them with wind and solar power stations with a total capacity of 8.2 GW. They will deliver more than 15 GWh.
This is the largest renewable energy project in Europe valued at 7 billion euros. The main investors will be municipal cooperatives, private companies and citizens.
The closure of mines and coal-fired power units is estimated at 384 million euros, said Fabian Huneke of the Energy Brainpool Institute. This includes the cost of closing the Hambach mine and the six oldest and least efficient coal-fired power plants by 2020, the Inden mines and six other power plants by 2022, as well as the Garzweiler mines and the last three blocks by 2025.
- France, Germany and the UK have become G20 leaders in green investment
The German financial transnational corporation AllianzSE and the NewClimate Institute are exploring the investment climate and investment in renewable energy development in all G20 countries. This year’s Allianz Climate and Energy Monitor 2018 report showed that the G20 should invest $ 886 billion annually in the energy sector to meet the climatic objectives of the Paris Agreement, according to Germanwatch. It should be mentioned that almost all G20 countries (with the exception of the United States) have agreed to fully limit their CO2 emissions by 2050.
Most G20 countries and a number of developing countries have fostered low-carbon energy investments last year. France grew to two positions and is now ranked first, while Germany and Britain share second and third place respectively. These countries have better political conditions, which are key criteria for long-term investment.
According to Professor Nicholas Hion, Managing Director of the NewClimate Institute, in countries with the most efficient economies, there are still weaknesses: there are not enough applicants on the French tenders, as a result of the introduction of new auction rules, investment in the development of wind energy will decrease, and the solar market energy in the UK stalled after political reforms.
- Endesa invests more than € 20 billion in energy
The Spanish energy group Endesa plans to increase its installed capacity of renewable energy by 30% and invest over 20 billion euros (net capital expenditure) by 2021, of which 2 billion euros in the development of renewable energy, 1.9 billion euros in the development of distribution networks , 1.2 billion euros in electricity generation, 0.7 billion euros in supplies and 0.6 billion euros in development of overseas territories, reports the independent information and consulting company Enerdata.
In addition, Endesa’s key element in its strategy is energy efficiency improvement through the digital reform of the grid. The company will spend 1 billion euros on smart networks (40% for network automation, 40% for network upgrades and 20% for other network transformations).
The key factor in this strategy is the decarbonisation of electricity production, which is, the reduction of CO2 emissions by 2020 by 47% compared to 2005 and by additional 44% by 2030.
- Germany has created an experimental CPV solar module with a 41.4% efficiency
The German Fraunhofer Solar Energy Research Institute has developed an experimental CPV solar module with high efficiency (41.4%) conversion of solar energy, as reported by Cleantechnica.
The secret of the new module lies in the use of achromatic lenses that focus sunlight on tiny compound (MJ) solar cells using modern materials and processes for better spectral matching and using conceptual models of highly concentrated photovoltaic cells (HCPV) with improved optical and interdependence ‘tangled constructions, including new approaches to light management’.
The CPVMatch project combines efforts of the researchers from Germany, Italy, Spain and France.
CPV modules can make a significant contribution to the development of solar power, providing far greater efficiency than of conventional solar cells.
- Denmark has invented a superconducting tape that will significantly reduce the cost of building wind farms
Under the EcoSwing project of the European Union in Denmark, a superconductive power line was used to upgrade the wind turbine, which would significantly reduce the cost, weight and size of the turbine. The cost of the turbine largely affects the cost of energy produced by wind power plants, reports Engadget.
The superconductive power line is made using a ceramic superconducting layer with gadolinium-barium-copper oxide, with a steel tape on the surface and a protection against metal oxide through layers of magnesium and silver. The same type of cryogenic cooling, which is commonly used in MRI scanners, is used for cryogenic cooling of a wind turbine.
This technology is still in the experimental stage. The next step is to develop a turbine that will take full advantage of the new technology and become easier, cheaper and more productive. All this can make renewable energy more affordable.
