As the urgency to take bold climate action grows, new analysis by the International Renewable Energy Agency (IRENA) finds that scaling-up renewable energy combined with electrification could deliver more than three quarters of the energy-related emission reductions needed to meet global climate goals. According to the latest edition of IRENA’s Global Energy Transformation: A Roadmap to 2050, launched at the Berlin Energy Transition Dialogue, pathways to meet 86 per cent of global power demand with renewable energy exist. Electricity would cover half of the global final energy mix. Global power supply would more than double over this period, with the bulk of it generated from renewable energy, mostly solar PV and wind.

The race to secure a climate safe future has entered a decisive phase,” said IRENA Director-General Francesco La Camera. “Renewable energy is the most effective and readily-available solution for reversing the trend of rising CO2 emissions. A combination of renewable energy with a deeper electrification can achieve 75 per cent of the energy-related emissions reduction needed.

An accelerated energy transition in line with the Roadmap 2050 would also save the global economy up to USD 160 trillion cumulatively over the next 30 years in avoided health costs, energy subsidies and climate damages. Every dollar spent on energy transition would pay off up to seven times. The global economy would grow by 2.5 per cent in 2050. However, climate damages can lead to significant socio-economic losses.

The shift towards renewables makes economic sense,” added Mr. La Camera. “By mid-century, the global economy would be larger, and jobs created in the energy sector would boost global employment by 0.2 per cent. Policies to promote a just, fair and inclusive transition could maximise the benefits for different countries, regions and communities. This would also accelerate the achievement of affordable and universal energy access. The global energy transformation goes beyond a transformation of the energy sector. It is a transformation of our economies and societies.

But action is lagging, the report warns. While energy-related CO2 emissions continued to grow by over 1 per cent annually on average in the last five years, emissions would need to decline by 70 per cent below their current level by 2050 to meet global climate goals. This calls for a significant increase in national ambition and more aggressive renewable energy and climate targets.

IRENA’s roadmap recommends that national policy should focus on zero-carbon long-term strategies. It also highlights the need to boost and harness systemic innovation. This includes fostering smarter energy systems through digitalisation as well as the coupling of end-use sectors, particularly transport, and heating and cooling, via greater electrification, promoting decentralisation and designing flexible power grids.

The energy transformation is gaining momentum, but it must accelerate even faster,” concluded Mr. La Camera. “The UN’s 2030 Sustainable Development Agenda and the review of national climate pledges under the Paris Agreement are milestones for raising the level of ambition. Urgent action on the ground at all levels is vital, in particular unlocking the investments needed to further strengthen the momentum of this energy transformation. Speed and forward-looking leadership will be critical – the world in 2050 depends on the energy decisions we take today.

CMBlu Projekt AG and Schaeffler Technologies AG & Co. KG have announced the signature of a joint development agreement (JDA) to cooperate in the production of large-scale energy storage systems. Over the past five years, CMBlu – in collaboration with research groups from German universities – has developed the novel and renewable Organic Flow Storage Technology for power grids up to prototype scale. On this basis, Schaeffler and CMBlu will jointly develop and industrialize commercial products to be marketed by CMBlu. The goal of both partners is to make a substantial contribution to a secure, efficient and sustainable power supply worldwide.

Organic Flow Batteries can be used flexibly as stationary energy storage units in the power grid and contribute to the balance between generation and consumption. The technology has diverse applications, for example in the intermediate storage of renewable energies or peak shaving in industrial plants. Another field of application is the charging infrastructure for electromobility. As buffer storage, the batteries contribute to the relief of medium-voltage grids, eliminating the need for upgrading due to additional loads. Ultimately, a decentralized charging infrastructure for electric vehicles will only be possible with powerful and scalable energy storage systems, such as Organic Flow Batteries.

The underlying technology is similar to the principle of conventional redox flow batteries. The electrical energy is stored in chemical compounds, which form electrolytes in water solution. In contrast to conventional, metal-based systems, organic molecules derived from lignin are used for storage. Lignin can be found in every plant such as trees or grasses. It is a naturally renewable source and is extracted in pulp and paper production as a waste product on a million-ton scale. This ensures lignin as a permanently available raw material for large-scale energy storage system.

All electrotechnical components in the energy converter have been adapted to these electrolytes and improved for cost-effective mass production. The entire value chain of the batteries can be realized locally. There are no import dependencies on individual countries. In addition, Organic Flow Battery Systems do not use rare earths or heavy metals, are non-flammable and therefore can be operated very safely. Due to their operating principle, the capacity of Organic Flow Systems can be scaled up independently of the electrical power and is limited only by the size of the storage tanks and the amount of electrolyte.

For industrialization, CMBlu has entered into a long-term cooperation agreement with Schaeffler for the development of large-scale energy storage systems with the aim of providing market-ready products. In the next step CMBlu will establish the full supply chain including all pre-products with other industry partners. In addition, a prototype production was set up in Alzenau. CMBlu has already signed contracts with reference customers to implement selected pilot projects over the next two years. As of 2021, the first commercial systems are planned.

From September this year, Acciona will supply 100% renewable electricity to the two main facilities of LATAM Airlines Group. The contract is part of the framework of both companies’ commitment to reduce the effects of climate change.

Through the contract, LATAM’s facilities at Arturo Merino Benítez Airport in Santiago de Chile, which include its corporate offices and the operation and maintenance base for its aircraft fleet, will be supplied with energy from renewable generation installations of Acciona.

This supply, covering 80% of LATAM’s consumption in Chile, will allow the airline to avoid the emission of 5,850 tonnes of CO2 to the atmosphere per year, producing the same air cleaning effect as that of 292,500 trees through photosynthesis.

Acciona’s energy portfolio in Chile consists of the 246-MWp El Romero Solar photovoltaic plant in the Atacama Desert and the 45-MW Punta Palmeras wind farm in the region of Coquimbo. It is currently building a second wind farm (San Gabriel, with a capacity of 183 MW) in La Araucanía, and over the next year will begin construction work on the Almeyda and Usya photovoltaic plants in the regions of Atacama and Antofagasta, respectively, and the Tolpán wind farm in La Araucanía.

MAN Diesel & Turbo has successfully commissioned seven 32/44CR diesel engines for the operation of a base load power plant in the Peruvian city of Iquitos. The power plant operator is a joint venture between the Israeli company Telemenia and V-Power – a power distributor that is mainly operated in Asia. The project, which had demanding requirements in terms of logistics, will from now on be supported by MAN PrimeServ – the company’s global after-sales service provider.

“MAN PrimeServ will supply spare parts to and provide service staff for the power plant in Iquitos up to 2027 as part of a Long Term Service Agreement (LTSA),” explains Dr. Michael Filous, Head of PrimeServ O&M at MAN Diesel & Turbo in Augsburg: “As part of the LTSA, an online service for real-time monitoring of the performance of the plant is also planned.”

With an output of around 78 MW, the power plant supplements the energy supply to the jungle city of Iquitos and its roughly 400,000 inhabitants. It replaces an outdated plant run by the local network operator. Due to the particular location of the city, which can be described as an island in the jungle and that can only be accessed by boat and airplane, the engines had to be delivered by water via the Amazonas. The engines were transported on barges from the Brazilian city of Manaus around two-thousand kilometers upstream to Iquitos.

Aguas Chañar has awarded Acciona Energía the supply of electricity to its main facilities, consisting of 100% renewable energy generated by the company in Chile.

Under the terms of the PPA contract signed by the companies, supplies will begin on 1 February 2018 for a long-term period, covering over 70% of Aguas Chañar’s needs in the Atacama region for consumption in a number of installations.

This 100% renewable electricity will avoid the emission of 26,500 tonnes of CO2 from thermal power plants per year, based on the energy mix of Chile.

All the energy supplied by Acciona will come from the company’s renewable installations in Chile, where it currently operates a 246 MWp photovoltaic plant (El Romero Solar) in the Atacama Desert and a 45 MW wind farm (Punta Palmeras) in the region of Coquimbo. It is now building a second wind farm with a capacity of 183 MW in the Araucanía Region.

Aguas Chañar, the exclusive integrated water cycle management rights holder in the Atacama region, works in the production and distribution of potable water and the collection, management and disposal of wastewater in the area. It provides a service to more than 270,000 people in nine municipalities in Atacama and operates 13 potable water treatment plants and 9 wastewater treatment facilities.

 “It is a great satisfaction for us to work with Aguas Chañar to supply 100% sustainable electricity supplies without any carbon footprint that are guaranteed by our renewable assets in Chile”, says Acciona Energía General Manager in Chile José Ignacio Escobar. “We are grateful for their trust in us, and that of other large Chilean companies, as this allows us to strengthen our corporate client portfolio in the country”, adds Mr. Escobar.

Aguas Chañar General Manager Claudio Bitran highlights the milestone of being the first company in the potable water production and distribution in Chile to supply more than 70% of its electricity consumption from non-conventional renewable energies. “This agreement ensures that our main processes function with clean energies and that we can take a step forward in caring for the environment by reducing our carbon footprint per liter produced. From now on, we can say that we are not only helping to produce water in the world’s most arid desert but doing it with clean energy, thanks to the endless sunshine in the Atacama region”.

With a total output capacity of more than 5.3 GW, offshore wind turbines make an increasing contribution to the security of Germany’s energy supply. They deliver clean power almost around the clock, every day of the year; industry representatives from AGOW, the BWE, the German Offshore Wind Energy Foundation, VDMA Power Systems and the WAB explained in Berlin during the presentation of the latest expansion figures for offshore wind energy.

According to an analysis of Deutsche WindGuard, a total of 1,169 wind turbines with an installed capacity of 5,387 MW were connected to the grid on 31 December 2017. Following the figures from AG Energiebilanzen, offshore wind turbines increased their power generation to 18.3 TWh in 2017. That is almost 50 percent more than in 2016 (12.3 TWh).

Two offshore wind farms with a capacity of 780 MW are currently under construction. For another five projects with a capacity of 1.5 GW, the final investment plan is now available. Until 2020, the legal extension of offshore wind energy up to a capacity of 7.7 GW is possible.

However, the reduction of the expansion path for wind energy at sea, as envisaged in the German renewables regulation (EEG) in 2017, particularly at the start of the 2020s, is slowing down this positive development of the offshore wind industry in Germany. Therefore, Cuxhavener Appell, initiated by Germany´s coastal states, trade unions and the offshore wind industry back in September 2017, called for an expansion of the offshore wind target to at least 20 GW by 2030 and 30 GW by 2035. Only higher expansion volumes in Germany and throughout the whole of Europe will ensure further and permanent cost reductions, as well as innovations in technological development. Furthermore, the free converter capacities that will arise following the tender results in Germany in spring 2018 should be used promptly. The results to date from the exploratory talks between the parties CDU, CSU and SPD also make this a logical course of action. The massive cost reductions in renewable energy open up new potential and clearly show that the relatively young technologies are now largely competitive to other forms of power generation.

A greater expansion of renewable energies is also necessary from a climate policy perspective. To achieve its domestic and international climate targets, the new federal government must create a political framework limiting the emission intensive power generation, whilst ensuring a higher expansion volume for renewable energies, and thereby adapting the energy system accordingly.

Higher expansion volume for more value creation and employment

Furthermore, a higher expansion volume in the offshore wind energy sector is highly important for more employment and value creation in Germany as an industrial location. Around 20,000 people are currently employed in the German offshore wind industry, at an annual turnover of approximately two billion Euro. Germany accounts for roughly 40 percent of all offshore wind industry employees across Europe. Although final production for the turbine manufacturers predominantly takes place in the north of Germany, the supply industry is spread across all federal states, in particular in North Rhine-Westphalia, Baden-Württemberg and Bavaria. Many companies in eastern Germany are also important suppliers to the wind industry.

Manufacturers and suppliers therefore need the prospect of their production capacities being utilized to retain and add industrial jobs. A stable and sustainable domestic market is the basis for expanding exports of European wind energy technologies. Wind turbine manufacturers currently have an export quota of more than 70 percent. Alongside Germany, Great Britain and the Netherlands are also showcasing new technologies and are attractive markets for offshore technologies. And the progress continues – manufacturers are now already working on turbines in the 10 MW class and beyond. It is therefore important to implement the plans for a test field for prototypes in German waters as soon as possible.

Germany can only retain its technological leadership in the field of offshore wind energy through intensified efforts in research and development. Future energy policy should not be oriented towards current technological knowledge – it must be open for innovation.

Priority for grid expansion and sector coupling

In addition to the expansion of renewable energies, the success of the energy transition in Germany is also dependent to a large extent upon grid expansion and the progress within sector coupling. Therefore, the new federal government must make the expansion of the large transmission grids a priority. It is vital to avoid further delays. Furthermore, all technical possibilities must be utilized in order to temporarily or permanently avoid bottlenecks in the grid. These include measures for improving the capacity of the existing grid. It is also important to check the amount of must-run capacities necessary for system stability.

Moreover, the regulatory obstacles to the further coupling of energy sectors must be removed as soon as possible. The mobility solutions of the future must be demonstrably based on renewable sources. Furthermore, access to heat grids needs to be improved and the barriers to direct delivery to industry must be eliminated.

Three MAN 18V32/40 generator sets are supplying the electricity for the crane facility at King Abdullah Port – the most modern port in Saudi Arabia. After successful commissioning by MAN Diesel & Turbo, the facility was handed over to the customer ESDM (Energy Solutions Developers and Managers). The three units run on marine diesel oil and function as generator sets supplying a total of approximately 26 MW of electricity to the crane facility. With a capacity of 65 tonnes, this facility is designed to be able to load and unload even the largest container ships in the world.

King Abdullah Port, the fastest growing port in the world, is part of King Abdullah Economic City, a unique urban development project which was started in 2005 and constitutes the largest building project in the history of Saudi Arabia. Located on the coast of the Red Sea between the two holy cities of Mecca and Medina, this new city is set to become the country’s second economic centre in future. Apart from serving the internal supply of the kingdom, the new port will also act as a strategic hub on the major trade route between Asia and Europe.

 

High temperatures throughout the year and an arid desert climate place particularly high demands on the technology used here. “The MAN 32/40 engine is a perfect match for the climatic conditions in Saudi Arabia and has already provided services in many other power plants on the Arabian Peninsula. The engine has proven itself in industrial applications due to its robustness, reliability and very long maintenance”.

Bookport concentrated solar power (CSP) plant in South Africa, built by Sener, Acciona and TSK, has set a new African record for the continuous, round-the-clock supply of electricity. Within the first month of commercial operation, the newly-inaugurated 50 MW Bokpoort CSP plant, produced electricity for a continuous period of 161 hours, equivalent to almost six days of continuous, full-load electricity – an African record.

CSP technology is considered an intermittent source of power which supplies electricity during daylight hours, when demand is highest. Nevertheless, Bokpoort’s design enables it to continue supplying electricity long after the sun has set thanks to a molten salt energy storage facility that can accumulate 9.3 hours of electricity production, the highest power storage facility on the African continent.

The Bokpoort CSP plant in the Northern Cape Province was built by a joint venture between Sener, Acciona, TSK and South Africa’s Crowie. They were awarded the EPC (Engineering, Procurement and Construction) project by the Saudi group ACWA Power, the plant’s owner and operator.

Round the clock electricity supply from a solar power plant is a significant milestone for South Africa and for the renewable industry as a whole, as it allows CSP technology to approximate the continuous power supply of conventional technologies such as hydroelectric, thermal or gas-fired power plants.Planta-Bokpoort2

In South Africa the country’s daily evening peak demand is from 5 pm to 9 pm and the newly introduced CSP Peak tariff means that developers are encouraged to have thermal storage capacity.

Bokpoort CSP has shown that due to the good design of the plant and the solar radiation available at the site, its 9.3 hours of thermal storage can easily be extended to allow round-the-clock continuous operations.

Nandu Bhula, CEO of Bokpoort CSP plant, declared: “Globally the biggest challenge of CSP has been its ability to produce energy consistently long after sunset. The performance of this plant is a clear indication that CSP technology can be used as a base-load capacity option in the same way as conventional power plants.”
