Aiming at innovative research and development in zero-carbon, low-carbon and green products, technologies and industrial applications, Siemens Energy has been on this path of sustainable development for more than ten years.
According to data from the International Energy Agency, energy use in the energy industry accounts for about 37% of global consumption, and carbon dioxide emissions also account for a large proportion. As China accelerates its “dual carbon” goal, during the 4th CIIE, as one of the world’s leading energy technology companies, Siemens Energy has brought many low-carbon and carbon-reduction solutions for energy industrial applications And products.
Zhang Tiangui, Executive Vice President of Siemens Energy Co., Ltd. and General Manager of Energy Industry Application Group Greater China, said that in the context of carbon neutrality, at Siemens Energy’s global headquarters, Energy Industry Application Group has established a dedicated sustainable development department with the goal of enabling energy The system becomes more sustainable.
In the process of transition to low-carbon, a series of mature and emerging technologies are needed. Siemens Energy helps China’s oil and gas and related process industry enterprises realize energy conservation and emission reduction and turn to green development by providing a powerful R-EAD_– dynamic equipment product portfolio, a full set of services, and electrification, automation and digital solutions.
Highlights of CIIE
At this year’s CIIE, Siemens Energy joined the “Energy Low-Carbon and Environmental Technology Zone” established for the first time. Through the interactive technology of augmented virtual reality, it focused on five themes: “Future-oriented power generation”, “Environmentally friendly power transmission”, and “Environmentally friendly power transmission”. Decarbonized Energy Industry Applications, “Hydrogen Energy, Enabling a Carbon-Free Future” and “Popular Future”, comprehensively present low-carbon technologies and products in the complete energy industry value chain. Specific to the energy industry application field, the focus is on the use of new energy-saving and emission-reduction products and technologies and new energy sources in the key processes and energy systems of oil and gas and process industries.
Siemens energy industry application field includes two major contents, one is products based on rotating equipment, and the other is the overall solution for industrial applications. Among them, the products are mainly small and medium-sized gas turbines and compressor units, and are oriented to petrochemical refining, shipbuilding, papermaking, and offshore oil and gas exploration platforms. The overall solution in the industrial application field is to completely cover the entire upstream, midstream and downstream industrial chain of oil, natural gas and other industries.
Zhang Tiangui said that in the oil and gas storage and transportation pipeline industry, Siemens Energy can provide corresponding solutions to help companies improve economic efficiency and reduce carbon dioxide emissions. “Related to clean energy, for example, compressed air energy storage technology can combine renewable energy such as wind energy and solar energy, use the high-power electric energy storage capacity of compressed air energy storage, overcome the shortcomings of renewable energy unstable power generation, and realize The stable output of renewable energy to better help the power grid peak and frequency modulation is one of the highlights of our energy industry applications.”
On the product side, “the rotating equipment we exhibited at the CIIE has been technologically innovated on the original compressor models to better improve energy efficiency and reduce power requirements. The increase in energy efficiency means that compressors will be The energy consumption of the drive end is reduced. From the perspective of carbon footprint, it has achieved the effect of reducing carbon.” Zhang Tiangui said.
“For example, our goal is to increase energy efficiency by 2 to 3 percentage points. For example, usually a medium-sized ethylene compressor unit consumes hundreds of millions of dollars in electricity a year, which means an increase in energy efficiency by 2 to 3 percentage points. , It means saving millions of electricity bills.” Zhang Tiangui said that this can not only reduce electricity bills and improve economic efficiency, but also save energy and achieve the goal of reducing emissions.
In addition to the new rotating equipment, there is also a solution called BlueDrivePlus C on site, which is a DC power station electric propulsion system specially applied to ships and offshore engineering ships. Its most important feature is that it greatly improves the traditional diesel power generation system of offshore ships. Overall efficiency. This brand-new product can improve electricity efficiency by 30%, which means that diesel waste is reduced by 30%, which is equivalent to a 30% reduction in carbon dioxide emissions.
Regarding the difficulties encountered in the application of crude oil and natural gas, Zhang Tiangui said, taking the flare gas of a refinery plant as an example, the flare gas needs to be burned no matter when the plant is shut down, accidents, etc., carbon dioxide and nitrogen oxygen cannot be avoided. Emissions of chemical compounds pollute the environment as well as a waste of energy.
For this reason, Siemens Energy is exploring some brand-new solutions. For example, on the one hand, it uses LNGo technology to liquefy these gases into liquefied natural gas during the front-end processing, instead of burning the gas in the traditional way; on the other hand, it also These gases can be used as fuel and sent to Siemens gas turbines for combustion to generate electricity, and the waste heat of combustion exhaust gas can be further recovered to form a combined cycle. In addition, Siemens has developed a brand-new Echogen solution that uses supercritical carbon dioxide to recycle waste heat and waste heat from exhaust gas emitted from combustion and use them to generate electricity. This is a brand-new approach for petrochemical companies to reduce carbon emissions.
For the decarbonization of various existing devices in the existing industrial field, Siemens Energy can achieve through new technological transformations and upgrades to existing power equipment. It is coal demand. “‘R-EAD’ is an important technical route of ours. Through the overall electrification automation and digital overall solution, combined with moving equipment to improve energy efficiency and strengthen operational efficiency.” Zhang Tiangui said.
In addition, the application of new energy, especially green hydrogen solutions, is also accelerating. Zhang Tiangui said, “We are also discussing with customers how to transition the gray hydrogen currently used in the petrochemical industry to blue hydrogen and other emission reductions, and reduce carbon. Siemens Energy has high-efficiency green hydrogen technology for the production of the footprint. In the future, we will certainly cooperate with oil and gas customers on green hydrogen solutions.”
Synchronous global R&D landing
In China, Siemens Energy Industry Application Group has established two factories, one is located in Huludao City, Liaoning Province, which mainly manufactures rotating equipment such as centrifugal compressors, reciprocating compressors and industrial steam turbines. One is located in Changzhou, Jiangsu. It focuses on electrification, automation and digitalization, and mainly provides electrical solutions for offshore ships and oil and gas platforms. These two plants provided full support for the entire Siemens Energy Industry Application Group in the localization process. The business of the Huludao plant will also extend to the integration of various systems for industrial applications.
“Our products are globalized products. Once the development of new products and new technologies is completed, they are basically launched simultaneously in all parts of the world.” Zhang Tiangui said, for example, compressors related to hydrogen energy, once the latest technologies and products are launched When it comes to the market, all products on the Chinese market will be produced and manufactured by the Huludao plant. “At present, the Huludao plant is already producing a full range of compressors and industrial steam turbine products, keeping pace with the global market.”
It is reported that Siemens Energy invested 1 billion euros in research and development expenses last year. Zhang Tiangui said that in the future, Siemens Energy Industry Application Group will continue to conduct research and development of new products and new solutions, including research and development of new technologies and new solutions. Only in this way can it help industrial customers in the oil and gas industry, shipbuilding, papermaking, etc. better Carry out “decarbonization”.
In the future, in the field of energy industry applications, with the promotion and use of new energy, especially hydrogen energy, higher requirements will be put forward on the hydrogen production equipment and transportation pipelines involved. Zhang Tiangui said that hydrogen production and transportation are inseparable from compressors, and technical requirements such as the level of hydrogen content, hydrogen liquefaction, and low-temperature compression pose new challenges to existing compressor products and technologies. For example, the existing reciprocating compressors can only be used for small-scale applications, while the atmospheric and high pressure ratio centrifugal compressors that are suitable for future hydrogen energy applications are under development, and the goal is to put them on the market around 2025.
In terms of digitization, Siemens energy industry applications are developed around the digitization of various key processes in the energy industry value chain, such as offshore oil and gas exploration, production, transportation and storage, etc., and developed Topsides 4.0 integrated solutions to integrate The compressor unit associated with oil and gas is combined with other functional modules more organically and efficiently than the power generation module, and the production end and the operation end are automated and digitally integrated.
“Intelligent digitalization not only means smarter operations, but also means more security. For example, offshore platforms are usually an isolated island, usually in the deep sea or remote areas, and digital twins are realized through remote control and diagnosis through digitalization, which can reduce the number of personnel. Being present can not only reduce the hidden dangers of personnel, but also ensure the safety of equipment.” Zhang Tiangui said.
Under the dual-carbon background, on the one hand, it is necessary to complete the 30·60 target, on the other hand, it is to ensure the security of energy supply. A brand new opportunity.” Zhang Tiangui said.
Just in April this year, Siemens Energy and Total signed a technical cooperation agreement to study sustainable solutions for reducing liquefied natural gas (LNG) emissions, focusing on LNG facilities and related power generation. The two parties will combine their respective technologies and expertise to provide industrial-stage solutions, such as gas turbines for hydrogen power generation, competitive all-electric power for natural gas liquefaction, and integration of renewable energy into the power system of the liquefaction plant and improve efficiency.
