Technologies to decarbonize the industry

Generating power with zero or low-carbon emissions for a carbon-neutral industry

​Urbanization, scarce resources, and climate change: Wherever we look, global challenges are spurring an increasing demand for efficient and low-/net-zero power generation, and energy from renewable sources is becoming more and more important. That’s why energy systems are already undergoing a rapid transformation – and adapting to the high shares of renewables that will be essential for future energy systems.

An efficient and cost-effective solution for the generation of heat and cold

During the next years, heat generation will be more and more electrified and decarbonized. Excess renewable energy can be converted into heat, paving the way to CO2-free heat. For industrial heating applications, our large-scale industrial heat pumps are an efficient solution to convert electricity to heat.

Lowering CO₂ by using hydrogen in gas turbines

There is an increasing need, and potential, for hydrogen to decarbonize power generation. Hydrogen capability of gas turbines to generate power and heat in existing as well as in new power plants built today  will ensure their future role supporting the energy transition.

Siemens Gamesa wind power

Our wind power business Siemens Gamesa builds and delivers powerful and reliable wind energy solutions. With 130 GW of installed capacity onshore and offshore, Siemens Gamesa provides access to clean, affordable and sustainable energy that keeps the lights on around the world.

Certify the source of green energy

Along with the energy transition, the global demand for sustainable manufacturing has never been higher. We have established a blockchain partner ecosystem and launched the Clean Energy Certificate. It can help you prove your product is manufactured from renewable sources.

A robust and resilient grid: key for a decarbonized industry

Power transmission and distribution is facing a lot of challenges, such as increased global demand, emphasis on sustainability, development of digital technologies balancing the increasing infeed of renewable energy sources, and more.

A decarbonized grid is crucial for the energy transition

To meet the challenge of fluctuating renewable energy, we are modernizing, expanding, and improving the stability and efficiency of our transmission and distribution network. This includes optimizing our transmission technologies to transport renewable energy to consumers quickly, over greater distances, with greater reliability, and with reduced energy losses.

Enhancing grid reliability and network stability

To ensure the successful transition to renewable energy sources, our high-voltage products and systems can help transport energy more efficiently and reliably. This will require expanding, automating and upgrading the transmission grid, as well as ensuring grid stability, so that electricity can be delivered in the right quantity, quality and reliability. 

Keeping your transmission equipment in safe operation

We provide top-notch services to ensure the highest level of performance, reliability, sustainability, and availability for power companies. We specialize in managing thousands of high-voltage assets, such as switchgears, transformers, FACTS, and HVDC substations, so that our customers can be confident in the success of their businesses. 

Moving towards net-zero by reducing green-house-gas emissions

The energy transition, and coming along with it decarbonization, creates a new era for the industry and industrial processes. The sector currently accounts for 38% of all energy used worldwide and a large share of global CO2 emissions. Yet, the world economy needs to keep going. But at a reduced level of green house gas emissions.

H2 as an energy carrier for sustainable economy

Generating green hydrogen efficiently requires innovative solutions — like the Silyzer product family. Using PEM (Proton Exchange Membrane) technology, the Silyzer is ideally suited for harnessing volatile energy generated from wind and solar. Combining high efficiency and high power density, our PEM electrolyzers ensure gas products of superior quality.

Gas to power solutions: bridging the gap

The share of renewable energy sources continues to increase. However, as these sources are intermittent, so is the electricity they generate- and their supply is not consistent. Hence, there is a need to develop an effective way to store this surplus electricity for distribution during periods of low wind and cloud cover. Natural gas can provide a reliable alternative, serving as a complement to renewable energy sources.

A huge potential for efficiency

Around half of the industry's energy consumption is compression. Compressor solutions can be standardized or customized in a variety of applications – such as hydrogen, CO2, on- or offshore oil and gas, natural gas transmission and distribution, air separation, (petro-)chemicals, and refining.

Cross-industry applications

Two topics have the potential to revolutionize industry: Digitalisation by having a major effect on both energy generation and consumption. Scaling up energy storage systems will be essential to address the fluctuation of renewables and to provide energy system flexibility.

Uncover value with digital solutions

Digital transformation is revolutionizing the way we live, work, travel, and play. It is promoting the safety, efficiency, inclusivity, and environmental friendliness of energy systems around the world. However, it is also introducing new security and privacy challenges and causing disruption to markets, businesses, and employees.

Your bridge into the future

Tomorrow's energy landscape places new demands on I&C – it must be scalable and cyber-secure – and it must be able to react flexibly to current developments, with innovative approaches. That is why our proven control system Omnivise T3000 is forging a new path, based on what has proven itself in daily business, and is building a bridge to the energy landscape of the future, piece by piece, with continued innovation.

Storage solutions for all purposes

Today, storage solutions supply power when needed, ensure grid stability, and support frequency regulation. They help with fluctuating power supply and demand. In a decarbonized world powered by renewables, batteries will store energy on a short-term basis, thermal and mechanical storage will provide industrial heat and electricity in the mid-term. And electrolyzers will convert any excess power generated by renewable energy sources into green hydrogen - for re-electrification or utilization in other sectors.

The central part for the future internet of energy

Edge technology is increasingly impacting the energy sector. Edge-enabled, high-voltage products will build the foundation for the Internet of Energy (IoE).  At the same time, edge technology on the product and substation level is complementary to the cloud on the enterprise level.
