adopt this technology for different applications and improve technology as

well as applications.

Growing up in the traditional steam turbine business for large nuclear, coal

and gas fired power plant, the last 10-15 years focused on new applications

like Double Reheat, Concentrated Solar Power and use of waste heat and

geothermal energy. This also includes sCO2 power cycles and turbine

technology.

Recent Achievements of European R&D on Supercritical CO2 Power Cycles

Jörg Starflinger Professor at and Head of the Institute of Nuclear Technology and Energy University of Stuttgart Stuttgart, Germany

Joerg Starflinger got his Diploma and Dr.-Ing. from Ruhr University Bochum.

In 1998, he joined Karlsruhe Institute of Technology as Post-Doc in the field

of hydrogen safety. He was coordinator of an EU FP6 Project on Supercritical

Water Cooled reactors and since then interested in supercritical fluid

applications. In 2010, he joined University of Stuttgart as Professor. He

initiated to build the SCARLETT test loop, which allows research with sCO2

as working fluid near the critical point. He and his doctoral students are

involved in several national and European projects on R&D of sCO2 power

cycles.

A spotlight on decentralised Energy-from-Waste Wednesday, October 13: 09:10 – 09:40

Simon Webb Managing Director Tidy Planet Limited Manchester, UK

Simon Webb is the managing director of Tidy Planet Energy, and he has over

30 years’ experience working within the environmental and engineering

sectors – and a 20-year+ tenure within the waste, recycling, and energy-

recovery arenas.

With an academic background in automotive engineering – and a passion for

problem-solving — Simon started his career path as a project engineer for a

company which specialised in industrial pollution control systems, including

solvent recovery systems and thermal oxidisers.

And throughout his many years in industry, he has worked in five countries

around the world, providing site-based solutions for customers in the

pharmaceutical, petrochemical, and printing industries.

With Tidy Planet Energy, Simon’s aim is to help transform the country’s

Energy-from-Waste landscape – assisting in building a robust, decentralised

energy-recovery infrastructure, which can cope with the country’s

contaminated plastic waste streams, such as RDF and SRF, instead of

shipping these resources overseas.

Waste Heat Recovery on Ships Wednesday, October 13: 13:00 – 13:30

Martin von Sydow Naval Architect Wallenius Marine AB Stockholm, Sweden

Since his graduation in Naval Architecture from CTH (Chalmers Technical

University, Gothenburg, Sweden) Martin von Sydow has been mainly

involved in the design and construction of newbuilding vessels and

Orcan Energy AG Monday, October 11: 15:20 – 16:20

Join us on a discovery tour - ORC 2021 Gold Sponsor Orcan Energy takes you to the geothermal plant in Kirchweidach, where Orcan's first geothermal system was installed in record time. The modular power plant approach enables the operator to dynamically switch between heat to district heating or electricity generation, as the single ORC modules can be turned on and off very quickly and also offer excellent partial load behavior. Orcan Energy co-founder Richard Aumann guides you directly to the Orcan ORC installations on site and explains how you can use Orcan efficiency PACKs to optimally exploit the energy potential of geothermal heat. In a subsequent product presentation, you will receive all highlights and important specifications of the efficiency PACK 050.100, before you can personally ask questions to the Orcan team in a live Q&A session.

Gas and Process and their strategic EPC partner Egesim will take delegates on a virtual video

tour of the 25 MW Özmen-3 geothermal ORC plant in Turkey. Rasmus Rubycz, Market

Manager New Energy, will share a footage from a recent walkthrough, which includes many

highlights, such as expander generator. After this tour, delegates can learn more about how

the plant came to life, as Rasmus will hold a video interview with Egesim’s Energy Projects

Coordinator, Cigir Diner. A live Q&A with the Atlas Copco team will round out the session.

Sponsor Exhibition

Our sponsors will give a unique 10 minutes pitch introducing their core activities and business

areas, bridging the gap between academia and industrial leaders in the field of ORC power

systems. This provides interesting insights into their activities. Afterwards, the gold sponsors

will be available to answer technical and more detailed questions at their virtual sponsor

booths. Also do not forget to visit our European Corner with highly interesting insights on

current EU projects in the ORC field. The featured European Research projects provide recent

results on current developments within the ORC field, such as waste heat recovery on ships

by advanced ORC systems (ENGIMMONIA Project), application of supercritical CO2 blends

to Concentrated Solar Plants (SCARABEUS Project) plants and reversible hybrid solar-

biomass ORC systems for buildings (SolBio Project).
