Our world is changing, and so should we.

The implications of climate change paired with the increase in energy demand result in major challenges for our planet. As temperatures climb globally, roughly 770 million people still do not have access to electricity, the heart of energy supply systems and long-range growth. And as we look into the future, we see even more reason to take sustainable action. Studies show that global energy demand could rise as much as 25% through 2040 – along with increased level of climate damaging greenhouse gases.

For this reason, the central question facing energy providers is this: How can we fulfill our task of meeting the growing demand for electricity worldwide and at the same time take on the responsibility of actively shaping the path to a climate-friendly future – in a sustainable, affordable and reliable manner? In short: How can we successfully implement a decarbonization journey that benefits our customers, societies at large and ourselves?

Power sector decarbonization
At Siemens Energy, we’re supporting our customers in transitioning to a more sustainable world using our innovative technologies, extensive experience, and an ambitious strategy to drive the decarbonization of global energy systems.

We adapt to new realities and seize emerging opportunities. But decarbonization takes time. It's not an overnight shift. We are pragmatic and thorough. Our approach is holistic and step by step.

We improve the efficiency of existing energy assets. We upgrade and modernize wherever possible. The transition away from conventional fuels comes next. We move from coal to gas and then to hybrid systems and cleaner fuels, such as hydrogen.

This is how we can lead the way to a deeply decarbonized world. This is how we support governments, utilities, and industry to a transformed system of energy.

Future Technologies
Siemens Energys future-focused technologies bridge the gap for emerging energy systems. As a partner and driver of the energy transition, we've focused our tech innovations across these areas: highly efficient transmission and storage of electricity, power generation with even lower or zero emissions, and reducing CO2 emissions in industrial processes.

Let's get to work and make real what matters. Let's energize society with our unique portfolio. Fuel-flexible and hydrogen-ready gas turbines. Combined cycle plants. Hybrid power and energy storage. Power-to-x and sector coupling. We have what it takes to decarbonize society.

In this keynote address, Paul Garbett, Head of Product & Solution Development for the Siemens Energy Gurgaon Engineering Hub, will show how turbomachinery can play a key role in this journey of decarbonizing energy.

Four panelists, two from Academia and two from Industry, will present their views on this topic drawn from their substantial experience. From academia you can expect coverage of conventional types of analyses that are only now being applied in industrial settings and novel methods that have changed the approach to diagnosing and predicting system dynamics. From industry we will hear of how novel methods have and can be expected to change the practice of analysis and design.

Future of Aviation and Disruptive Innovation
Since the first flight in 1903, the aviation industry has always been a high tech industry, and continuous progress in the development and adoption of technologies has been its hallmark. The innumerable challenges and changes that were embraced by the aviation industry were driven by a host of different factors such as geo political developments, global and regional economy, evolution of the transportation industry, design and manufacturing technologies, and environment. With each passing decade these factors coupled with technological advancements have defined the nature of the aviation industry and its products. The proposed talk will focus on present day aviation industry, new aircraft configurations, technology trends, and the design of future aircraft systems.
