As a first step an SGT-800 test turbine has been installed at the Rya combined heat and power plant (CHP) for the validation of 3D printed burners which would then allow for testing of different fossil-free fuels in the plant. The production of gas turbine burners using additive manufacturing (AM) makes a decisive contribution to accelerating the research and development process for new technologies that contribute to a greener energy supply.

Recently, the AM team within Siemens Gas & Power initiated the development of a new accelerated validation process for new technologies and components and now this process is already working in the Rya CHP plant. The special test engine is installed at the plant to support new developments.

"The Rya CHP plant plays an important role in Gothenburg's electricity supply," said Alf Engqvist, CEO of Göteborg Energi. "Working together with Siemens we want to explore the possibilities for the conversion of both electric power and heat production as pieces of the puzzle in our work for fossil-free energy independence."

There is global demand for new climate-smart solutions and Siemens' technology and solutions are addressing this need. For example, converting a coal power plant into a modern gas-fired combined cycle power plant, such as the Rya CHP plant in Gothenburg, can reduce carbon dioxide emissions by about two-thirds. By co-burning natural gas with an increasing share of hydrogen or biofuel, emissions can then be further reduced gradually.

"In our collaboration with Göteborg Energi we see the possibility to verify the viability of several different renewable fuels, such as hydrogen, on a larger scale, first in Sweden and then in other parts of the world," said Thorbjoern Fors, CEO Siemens Distributed Generation and Oil & Gas Services Business. "With this cooperation, Göteborg Energi and the Rya CHP plant are driving innovation toward new solutions and green power together with us.

"Our goal is to run the SGT-600, -700 and -800 gas turbine combustors 100 percent fossil free, for example with hydrogen, in the near future," continued Fors. "This is a unique cooperation between Siemens and a customer that can demonstrate the varied possibilities for sustainable and cost-effective fuels as our industry and societies look to reduce carbon emissions around the world."

The Rya combined cycle power plant was delivered turnkey by Siemens 2006 and includes three SGT-800 gas turbines.

The JAC gas turbine shipped for this project is for a power plant in Chonburi Province, one of two 2,650MW power plants being built in Chonburi and Rayong provinces, approximately 130 kilometers southeast of Bangkok. Commercial operation is scheduled to start in 2021. After startup, the plants will use natural gas as their main fuel source, with the electric power generated to be sold to the Electricity Generating Authority of Thailand (EGAT). The project will support the steady economic development in Thailand with a highly efficient source of clean energy.

Puerto Rico Governor Wanda Vazquez said, "The three generators provide the opportunity for fast response in the event of an emergency or situation where we lose energy in the metropolitan area. In eight to ten minutes we can energize the system and provide electricity to about 40,000 customers. Critical services such as hospitals in the metropolitan area will also have that security."

"The three mega-generators can meet the demand for facilities such as the Bayamón Regional Hospital, the Río Piedras Medical Center, and the Golden Mile in Hato Rey, as well as safeguard the daily operations of the Luis Muñoz Marín International Airport in Isla Verde," confirmed Jose Ortiz, Executive Director of PREPA. "Although they are physically located at the Palo Seco plant, the equipment is portable, so they can be moved to isolated areas that, during emergencies, do not have transmission capacity," continued Ortiz.

"As Puerto Rico transforms its grid architecture, the availability of the FT8 MOBILEPAC brings instant peace of mind to PREPA and its customers," noted PWPS President and CEO Raul Pereda. "For the long term, this technology is a multi-faceted solution that helps to achieve resilience when extreme weather hits and allows PREPA to move toward integration with the new renewable portfolio standard. Its energy efficiency and fast-start demand response provide significant flexibility when dealing with the challenge of uncertain load forecasts and supplies reliable power when Puerto Rico needs it most."
