67-554: The company employs around 4000 people and operates in 28 sites worldwide, including in countries such as France, England, the USA, Mexico, Brazil, Peru, Singapore, China, and Vietnam. The company was founded in Dessau: around Easter 1859, master locksmith Gottfried Polysius opened a workshop in Dessau with an apprentice and laid the foundations for today's company with his locksmith's shop and

134-495: A just transition that addresses these concerns. Recently, an energy crisis is upon the nations of Europe as a result of dependence on Russia's natural gas, which was cut off during the Russia-Ukraine war. This goes to show that humanity is still heavily dependent on fossil fuel energy sources and care should be taken to have a smooth transition, less energy-shortage shocks cripple the very efforts to effectively energise

201-426: A goal to achieve in the future – not as a concept to analyse past trends. When looking at the sheer amount of energy being used by humankind, the picture is one of ever-increasing consumption of all the main energy sources available to humankind. For instance, the increased use of coal in the 19th century did not replace wood consumption, indeed more wood was burned. Another example is the deployment of passenger cars in

268-497: A high integration of wind and solar energy. They can be addressed by operating reserves . Large-scale batteries can react within seconds and are increasingly used to keep the electricity grid stable. 100% renewable energy is the goal of the use renewable resources for all energy. 100% renewable energy for electricity, heating, cooling and transport is motivated by climate change , pollution and other environmental issues, as well as economic and energy security concerns. Shifting

335-627: A majority shareholding in Polysius. In 1992, Krupp Polysius was integrated into the Krupp Plant engineering division - a group structure of Fried. Krupp AG Hoesch-Krupp. In 1999, 140 years after the company was founded, it merged with the Thyssen Group to form ThyssenKrupp in what was one of Germany's first hostile takeovers. Polysius is now part of the international ThyssenKrupp Technologies division. Acquisitions strengthened Polysius in

402-617: A policy framework, the Africa Mining Vision, to leverage the continent's mineral reserves in pursuit of sustainable development and socio-economic transformation. Achieving these goals requires mineral-rich African economies to transition from commodity export to manufacture of higher value-added products. From 2010 to 2019, the competitiveness of wind and solar power substantially increased. Unit costs of solar energy dropped sharply by 85%, wind energy by 55%, and lithium-ion batteries by 85%. This has made wind and solar power

469-480: A scarcity of accessible (e.g. affordable) wood, and eighteenth century glass-works "operated like a forest clearing enterprise". When Britain had to resort to coal after largely having run out of wood, the resulting fuel crisis triggered a chain of events that two centuries later culminated in the Industrial Revolution . Similarly, increased use of peat and coal were vital elements paving the way for

536-436: A single year to be reallocated to provide oil and gas workers with a new career of approximately equivalent pay. In non-electrified rural areas, the deployment of solar mini-grids can significantly improve electricity access. Employment opportunities by the green transition are associated with the use of renewable energy sources or building activity for infrastructure improvements and renovations. Another important driver

603-404: A third change to strict conservation and to the renewed use of coal and to permanent renewable energy sources like solar power ." The term was later globalised after the 1979 second oil shock, during the 1981 United Nations Conference on New and Renewable Sources of Energy. From the 1990s, debates on energy transition have increasingly taken climate change mitigation into account. Parties to

670-543: Is energy security and independence, with increasing importance in Europe and Taiwan because of the 2022 Russian invasion of Ukraine . Unlike Europes 2010s dependence on Russian gas, even if China stops supplying solar panels those already installed continue generating electricity. Militaries are using and developing electric vehicles, particularly for their stealthiness, but not tanks . As of 2023 renewable energy in Taiwan

737-477: Is aiming for 200 GW by 2035, produced by 150 additional reactors. With the switch to clean energy sources where power is generated via electricity, end uses of energy such as transportation and heating need to be electrified to run on these clean energy sources. Concurrent with this switch is an expansion of the grid to handle larger amounts of generated electricity to supply to these end uses. Two key areas of electrification are electric vehicles and heat pumps. It

804-422: Is by lobbying local and national governments. Historically, the fossil fuel lobby has been highly successful in limiting regulations. From 1988 to 2005, Exxon Mobil , one of the largest oil companies in the world, spent nearly $ 16 million in anti-climate change lobbying and providing misleading information about climate change to the general public. The fossil fuel industry acquires significant support through

871-447: Is easier to sustainably produce electricity than it is to sustainably produce liquid fuels. Therefore, adoption of electric vehicles is a way to make transport more sustainable. While electric vehicle technology is relatively mature in road transport, electric shipping and aviation are still early in their development, hence sustainable liquid fuels may have a larger role to play in these sectors. A key sustainable solution to heating

938-428: Is economically important in some regions, and a transition to renewables would decrease its viability and could have severe impacts on the communities that rely on this business. Not only do these communities face energy poverty already, but they also face economic collapse when the coal mining businesses move elsewhere or disappear altogether. This broken system perpetuates the poverty and vulnerability that decreases

1005-520: Is electrification ( heat pumps , or the less efficient electric heater ). The IEA estimates that heat pumps currently provide only 5% of space and water heating requirements globally, but could provide over 90%. Use of ground source heat pumps not only reduces total annual energy loads associated with heating and cooling, it also flattens the electric demand curve by eliminating the extreme summer peak electric supply requirements. However, heat pumps and resistive heating alone will not be sufficient for

1072-404: Is expected to reshape geopolitical power by reducing reliance on long-distance fossil fuel trade and enhancing the importance of regional energy markets. A renewable energy transition can present negative social impacts for some people who rely on the existing energy economy or who are affected by mining for minerals required for the transition. This has led to calls for a just transition , which

1139-524: Is far too small to help in a blockade. Centralised facilities such as oil refineries and thermal power plants can be put out of action by air attack, whereas although solar can be attacked decentralised power such as solar and wind may be less vulnerable. Solar and batteries reduces risky fuel convoys. However large hydropower plants are vulnerable. Some say that nuclear power plants are unlikely to be military targets, but others conclude that civil NPPs in war zones can be weaponised and exploited by

1206-470: Is feasible and economically viable. A cross-sectoral, holistic approach is seen as an important feature of 100% renewable energy systems and is based on the assumption "that the best solutions can be found only if one focuses on the synergies between the sectors" of the energy system such as electricity, heat, transport or industry. In the 1970s and 1980s, nuclear power gained a large share in some countries . In France and Slovakia more than half of

1273-445: Is predicted to become a driver of sustainable economic development. The International Energy Agency (IEA) has identified 37 minerals as critical for clean energy technologies and estimates that by 2050 global demand for these will increase by 235 per cent. Africa has large reserves of many of these so-called "green minerals, such as bauxite , cobalt , copper , chromium , manganese and graphite . The African Union has outlined

1340-674: Is required to mitigate the effects of climate change . Coal, oil and gas combustion account for 89% of CO 2 emissions and still provide 78% of primary energy consumption. Despite the knowledge about the risks of climate change and the increasing number of climate policies adopted since the 1980s, however, energy transitions have not accelerated towards decarbonization beyond historical trends and remain far off track in achieving climate targets. The deployment of renewable energy can generate co-benefits of climate change mitigation : positive socio-economic effects on employment, industrial development, health and energy access. Depending on

1407-558: The Dutch Golden Age , roughly spanning the entire 17th century. Another example where resource depletion triggered technological innovation and a shift to new energy sources is 19th century whaling : whale oil eventually became replaced by kerosene and other petroleum-derived products. To speed up the energy transition it is also conceivable that there will be government buyouts or bailouts of coal mining regions. A rapid energy transition to very-low or zero-carbon sources

1474-491: The IPCC defines as, "A set of principles, processes and practices that aim to ensure that no people, workers, places, sectors, countries or regions are left behind in the transition from a high-carbon to a low carbon economy ." Use of local energy sources may stabilise and stimulate some local economies, create opportunities for energy trade between communities, states and regions, and increase energy security . Coal mining

1541-519: The Industrial Revolution from 1760 onwards, from wood and other biomass to coal , followed by oil and later natural gas . Over three-quarters of the world's energy needs are met by burning fossil fuels , but this usage emits greenhouse gases. Energy production and consumption are responsible for most human-caused greenhouse gas emissions. To meet the goals of the 2015 Paris Agreement on climate change, emissions must be reduced as soon as possible and reach net-zero by mid-century. Since

1608-776: The Stahlinstitut VDEh . Energy transition An energy transition (or energy system transformation ) is a major structural change to energy supply and consumption in an energy system . Currently, a transition to sustainable energy is underway to limit climate change . Most of the sustainable energy is renewable energy . Therefore, another term for energy transition is renewable energy transition . The current transition aims to reduce greenhouse gas emissions from energy quickly and sustainably, mostly by phasing-down fossil fuels and changing as many processes as possible to operate on low carbon electricity . A previous energy transition perhaps took place during

1675-672: The adaptive capacity of coal mining communities. Potential mitigation could include expanding the program base for vulnerable communities to assist with new training programs, opportunities for economic development and subsidies to assist with the transition. Increasing energy prices resulting from an energy transition may negatively impact developing countries including Vietnam and Indonesia. Increased mining for lithium, cobalt, nickel, copper, and other critical minerals needed for expansion of renewable energy infrastructure has created increased environmental conflict and environmental justice issues for some communities. A large portion of

1742-465: The chemical industry with an expected large-scale implementation by 2025. A shift in energy sources has the potential to redefine relations and dependencies between countries, stakeholders and companies. Countries or land owners with resources – fossil or renewable – face massive losses or gains depending on the development of any energy transition. In 2021, energy costs reached 13% of global gross domestic product . Global rivalries have contributed to

1809-509: The 20th century. This evolution triggered an increase in both oil consumption (to drive the car) and coal consumption (to make the steel needed for the car). In other words, according to this approach, humankind never performed a single energy transition in its history but performed several energy additions. Contemporary energy transitions differ in terms of motivation and objectives, drivers and governance. As development progressed, different national systems became more and more integrated becoming

1876-617: The United States and was awarded American citizenship in 1923. While working as an engineer at Polysius , he invented the Lepol kiln, which reduced the amount of energy that was needed to produce cement and the processing of iron ore. (Lepol is a combination of Lellep and Polysius). In recognition of his engineering work, in 1960 he received, along with Robert Durrer the Carl Lueg Commemorative Medal from

1943-745: The agreement committed "to limit global warming to "well below 2 °C, preferably 1.5 °C compared to pre-industrial levels". This requires a rapid energy transition with a downshift of fossil fuel production to stay within the carbon emissions budget . In this context, the term energy transition encompasses a reorientation of energy policy . This could imply a shift from centralized to distributed generation. It also includes attempts to replace overproduction and avoidable energy consumption with energy-saving measures and increased efficiency . The historical transitions from locally supplied wood, water and wind energies to globally supplied fossil and nuclear fuels has induced growth in end-use demand through

2010-483: The business area was dissolved, which led to the renaming of thyssenkrupp Industrial Solutions GmbH into two independent companies: thyssenkrupp Polysius GmbH and thyssenkrupp Uhde GmbH. In September 2023, the thyssenkrupp Polysius, thyssenkrupp Uhde, thyssenkrupp Rothe Erde (Bearings business unit) and thyssenkrupp Nucera business units were merged under the umbrella of the newly created Decarbon Technologies segment. With

Levelized costs for combined onshore wind or solar with storage for a few hours are already lower than for gas peaking power plants . In 2021, the new electricity generating capacity of renewables exceeded 80% of all installed power.

2144-573: The country and the deployment scenario, replacing coal power plants can more than double the number of jobs per average MW capacity. The energy transition could create many green jobs , for example in Africa. The costs for retraining workers for the renewable energy industry was found to be trivial for both coal in the U.S. and oil sands in Canada. The latter of which would only demand 2–6% of federal, provincial, and territorial oil and gas subsidies for

2211-476: The demand for complete plants resulted in an unusually high capital commitment and entailed a variety of technological and commercial risks. The owners of Polysius realized that the financial demands on the company would sooner or later exceed the possibilities of a family business and therefore brought in the Essen-based Fried. Krupp GmbH as a shareholder. In 1971, Essener Fried. Krupp GmbH acquired

2278-445: The dependence on local weather conditions. With highly variable prices, electricity storage and grid extension become more competitive. Researchers have found that "costs for accommodating the integration of variable renewable energy sources in electricity systems are expected to be modest until 2030". Furthermore, "it will be more challenging to supply the entire energy system with renewable energy". Fast fluctuations increase with

2345-408: The driving forces of the economics behind the low carbon energy transition. Technological innovations developed within a country have the potential to become an economic force. The energy transition discussion is heavily influenced by contributions from the fossil fuel industries . One way that oil companies are able to continue their work despite growing environmental, social and economic concerns

2412-518: The electrical power is still nuclear. It is a low carbon energy source but comes with risks and increasing costs. Since the late 1990s, deployment has slowed down. Decommissioning increases as many reactors are close to the end of their lifetime or long before because of anti-nuclear sentiments. Germany stopped its last three nuclear power plants by mid April 2023. On the other hand, the China General Nuclear Power Group

2479-409: The electrification of industrial heat. This because in several processes higher temperatures are required which cannot be achieved with these types of equipment. For example, for the production of ethylene via steam cracking temperatures as high as 900 °C are required. Hence, drastically new processes are required. Nevertheless, power-to-heat is expected to be the first step in the electrification of

2546-408: The entire life cycle of cement plants, including inspections, maintenance and the supply of innovative OEM spare parts. With a total of 20 service offices in 18 countries and 5 service centers, the company has a global presence. In addition to the cement industry, thyssenkrupp Polysius also operates in other sectors: Otto Lellep Otto Georg Lellep (29 September 1884 – 18 October 1975 )

2613-503: The existing banking and investment structure. The concept that the industry should no longer be financially supported has led to the social movement known as divestment. Divestment is defined as the removal of investment capital from stocks, bonds or funds in oil, coal and gas companies for both moral and financial reasons. Banks, investing firms, governments, universities, institutions and businesses are all being challenged with this new moral argument against their existing investments in

2680-704: The fossil fuel industry and many; such as Rockefeller Brothers Fund, the University of California, New York City and more; have begun making the shift to more sustainable, eco-friendly investments. In 2024 the International Renewable Energy Agency (IRENA) projected that by 2050, over half of the world's energy will be carried by electricity and over three-quarters of the global energy mix will be from renewables. Although overtaken by both biomass and clean hydrogen, fossil fuels were still projected to supply 12% of energy. The transition

2747-409: The global workforce works directly or indirectly for the fossil fuel economy . Moreover, many other industries are currently dependent on unsustainable energy sources (such as the steel industry or cement and concrete industry ). Transitioning these workforces during the rapid period of economic change requires considerable forethought and planning. The international labor movement has advocated for

2814-521: The growth potential of this technology is limited. Wind and solar power are considered more scalable, but still require vast quantities of land and materials. They have higher potential for growth. These sources have grown nearly exponentially in recent decades thanks to rapidly decreasing costs. In 2019, wind power supplied 5.3% worldwide electricity while solar power supplied 2.6%. While production from most types of hydropower plants can be actively controlled, production from wind and solar power depends on

2881-404: The hostile forces not only for impeding energy supplies (and thus shattering the public morale of the adversary) but also for blackmailing and coercing the decisionmakers of the attacked state and their international allies with a vision of man-made nuclear disaster. For many developing economies, for example in the mineral-rich countries of Sub-Saharan Africa, the transition to renewable energies

2948-534: The installation of energy storage and super grids are vital to enable the use of variable, weather-dependent technologies. However fossil-fuel subsidies are slowing the energy transition. An energy transition is a broad shift in technologies and behaviours that are needed to replace one source of energy with another. A prime example is the change from a pre-industrial system relying on traditional biomass, wind, water and muscle power to an industrial system characterized by pervasive mechanization, steam power and

3015-486: The integration of renewable energy, local electricity production is becoming more variable. It has been recommended that " coupling sectors , energy storage , smart grids , demand side management , sustainable biofuels , hydrogen electrolysis and derivatives will ultimately be needed to accommodate large shares of renewables in energy systems". Fluctuations can be smoothened by combining wind and sun power and by extending electricity grids over large areas . This reduces

3082-419: The integration of renewable energy. By 2040, the grid must expand by more than 80 million kilometers to manage renewable sources, which are projected to account for over 80% of the global power capacity increase over the next two decades. Failure to enhance grid infrastructure timely could lead to an additional 58 gigatonnes of CO2 emissions by 2050, significantly risking a 2°C global temperature rise. With

3149-461: The introduction of the new segment, thyssenkrupp is positioning itself as a leading technology company for the energy transition . The company's comprehensive competencies for the green transformation will be made fully visible. The main field of activity of thyssenkrupp Polysius GmbH is the cement industry. The company offers both individual machines and complete plants for cement production. In addition, thyssenkrupp Polysius provides services along

3216-576: The large, international systems seen today. Historical changes of energy systems have been extensively studied. While historical energy changes were generally protracted affairs, unfolding over many decades, this does not necessarily hold true for the present energy transition, which is unfolding under very different policy and technological conditions. For current energy systems, many lessons can be learned from history. The need for large amounts of firewood in early industrial processes in combination with prohibitive costs for overland transportation led to

3283-497: The largest scale storage technology is pumped storage hydroelectricity , accounting for the great majority of energy storage capacity installed worldwide. Other important forms of energy storage are electric batteries and power to gas . The "Electricity Grids and Secure Energy Transitions" report by the IEA emphasizes the necessity of increasing grid investments to over $ 600 billion annually by 2030, up from $ 300 billion, to accommodate

3350-430: The late 2010s, the renewable energy transition has also been driven by the rapidly falling cost of both solar and wind power . Another benefit of the energy transition is its potential to reduce the health and environmental impacts of the energy industry . Heating of buildings is being electrified , with heat pumps being the most efficient technology by far. To improve the flexibility of electrical grids ,

In October 2009, the 150th anniversary of the company was celebrated with three days of festivities in Neubeckum. In 2014, the two previously independent plant engineering companies thyssenkrupp Uhde and Thyssenkrupp Resource Technologies merged to form thyssenkrupp Industrial Solutions, headquartered in Essen . The company offers chemical, refinery and industrial plants as well as associated services such as planning, maintenance and training. As of May 31, 2023,

Besides money cabinets, the company also produced drains and vibrating screens. In addition to agricultural machinery, Polysius also produced grain mills, brewery and distillery equipment. He

3551-407: The other suggests the term "energy additions" as better reflecting the changes in global energy supply in the last three centuries. The chronologically first discourse was most broadly described by Vaclav Smil . It underlines the change in the energy mix of countries and the global economy. By looking at data in percentages of the primary energy source used in a given context, it paints a picture of

3618-493: The rapid expansion of engineering research, education and standardisation. The mechanisms for the whole-systems changes include new discipline in Transition Engineering amongst all engineering professions, entrepreneurs, researchers and educators. Historic approaches to past energy transitions are shaped by two main discourses. One argues that humankind experienced several energy transitions in its past, while

3685-449: The reference. Other renewable energy sources include bioenergy , geothermal energy and tidal energy , but they currently have higher net lifetime costs. By 2022, hydroelectricity is the largest source of renewable electricity in the world, providing 16% of the world's total electricity in 2019. However, because of its heavy dependence on geography and the generally high environmental and social impact of hydroelectric power plants,

3752-461: The term energy transition was coined by politicians and media. It was popularised by US President Jimmy Carter in his 1977 Address on the Nation on Energy, calling to "look back into history to understand our energy problem. Twice in the last several hundred years, there has been a transition in the way people use energy ... Because we are now running out of gas and oil , we must prepare quickly for

3819-455: The total global primary energy supply to renewable sources requires a transition of the energy system , since most of today's energy is derived from non-renewable fossil fuels . Research into this topic is fairly new, with few studies published before 2009, but has gained increasing attention in recent years. The majority of studies show that a global transition to 100% renewable energy across all sectors – power, heat, transport and industry –

3886-405: The use of coal. The IPCC does not define energy transition in the glossary of its Sixth Assessment Report but it does define transition as: "The process of changing from one state or condition to another in a given period of time. Transition can occur in individuals, firms, cities, regions and nations, and can be based on incremental or transformative change." After the 1973 oil crisis ,

3953-538: The way energy is produced, distributed, stored, and consumed. For a society to replace one form of energy with another, multiple technologies and behaviours in the energy system must change. Many climate change mitigation pathways envision three main aspects of a low-carbon energy system: The most important energy sources in the low carbon energy transition are wind power and solar power . They could reduce net emissions by 4 billion tons CO 2 equivalent per year each, half of it with lower net lifetime costs than

4020-415: The weather. Electrical grids must be extended and adjusted to avoid wastage. Dammed hydropower is a dispatchable source, while solar and wind are variable renewable energy sources. These sources require dispatchable backup generation or energy storage to provide continuous and reliable electricity. For this reason, storage technologies also play a key role in the renewable energy transition. As of 2020,

4087-433: The world's energy systems as having changed significantly over time, going from biomass to coal, to oil, and now a mix of mostly coal, oil and natural gas. Until the 1950s, the economic mechanism behind energy systems was local rather than global. The second discourse was most broadly described by Jean-Baptiste Fressoz. It emphasises that the term "energy transition" was first used by politicians, not historians, to describe

Just 10 years after the new start, Polysius employed 600 people in Germany and 100 abroad. In 1951, the first complete cement plant was delivered to Syria. In order to remain competitive, the company was forced to install ever larger plants. As the value of individual orders increased, the total number of orders placed worldwide steadily decreased. In addition,

After Polysius' death, his sons Otto and Max Polysius successfully continued the company. The construction of cement plants became particularly important. In 1893, the company exhibited at the World's Fair in Chicago. 1898 saw the design and manufacture of the first rotary cement kiln in Europe. This

Krupp had insisted on the use of forced labour even when the German military suggested that some work should be performed by free German workers for security reasons. After the end of the Second World War, Polysius started up again in Dessau in 1946. At the same time, Bernd Helming and Curt Prüssing, a son-in-law of Max Polysius, founded Westpol GmbH in Neubeckum, which
