Research, development and training organisation GTI has signed a Memorandum of Understanding (MoU) with Korea Electric Power Research Institute (KEPRI) to develop new technologies for supercritical carbon dioxide (sCO2) power cycles.

Such power cycles lend themselves to higher power conversion efficiencies and very compact turbomachinery, resulting in lower capital costs, reduced plant size and footprint, and greater flexibility.

Under this agreement, GTI and KEPRI, a unit of Korea Electric Power Company (KEPCO), will explore opportunities for joint research and development on sCO2 technologies over the next five years.

The partners will cooperate, share technical information, and potentially exchange research staff for sCO2 technology development and commercialisation.

“We’re pleased to be a part of this collaboration,” said Michael Rutkowski, GTI’s Senior Vice-President of Research and Technology Development.

“Transformational sCO2-based power cycles offer dramatically improved efficiencies, economics, and environmental performance.”

“KEPRI is a pioneering company that shares our focus on technology innovation to efficiently deliver lower-cost electric power with lower emissions.”

“Together we will contribute to a greater understanding of sCO2-based power generation as a clean, compact, and high-efficiency technology option.”

Dr. Jung Bin Lee, KEPCO Director General of Climate Change and Environment Laboratory, added, “KEPCO is very excited about working with GTI. The organisation has significant experience in power generation systems and is a recognised gas industry partner worldwide, and these attributes will help us in the global power generation market.”

“We will leverage our complementary skills and expertise to develop new generation systems and advance this technology towards commercial adoption.”

Since 2014, KEPCO has been focused on sCO2 power generation as a key strategic technology, investing in indirectly heated sCO2 technologies and exploring different heat sources and system capacities. The company is involved in a number of active R&D projects.

KEPCO is a Steering Committee member in the GTI-led Joint Industry Partnership developing the Supercritical Transformational Electric Power (STEP) Demo.

This first-of-a-kind 10 MWe sCO2 pilot plant will demonstrate a fully integrated functional power cycle in a test facility configured to enable optimization of sCO2 components and subsystems.

When completed, it will be the largest sCO2 demonstration facility of its kind in the world. With DOE-NETL support, GTI is leading the programme development team together with Southwest Research Institute (SwRI) and General Electric Global Research (GE).
