About THEMES

THEMES has assembled a team of experts with over 150 years of experience in developing and commercializing emerging technologies for the largest O&G companies in the world. Our team is dedicated to driving innovation and creating environmentally sustainable economic solutions to decarbonize electricity grids

Today, THEMES offers a Long Duration Energy Storage solution that can deliver 12-24 hours of Energy Storage at 100+ MW scales using proven adiabatic CAES surface plant with repurposed idle oil & gas well subsurface storage. At grid-scale, coupled with variable renewable generation, our solution enables the cheapest carbon-free electricity at a cost comparable with or lower than natural gas power generation.

Our team is using its prior O&G knowledge to develop subsurface solutions for other LDES technologies; we are interested in working with Thermal and Mechanical energy storage technologies to continue advancing the deployment of energy storage solutions.

Dr. Ram Shenoy

Over his 25-year oil & gas industry career, Dr. Shenoy led research, engineering, manufacturing and development of first of a kind infrastructure at Schlumberger (now SLB). In his last position at SLB as VP of Research, Dr. Shenoy managed a research budget of $130 million pa. At ConocoPhillips, he was involved in several multibillion upstream oil & gas infrastructure projects, such as the LNG projects in Western Australia, and the oil sands development in Alberta Canada. As former executive director of the Project Production Institute, Dr. Shenoy is an expert in the application of operations science methods to execute large infrastructure projects.

Dr. Ashok Krishna

Dr. Krishna has led the licensing, engineering design, construction and commissioning of many clean fuels technology plants in the refining industry. Roughly 40% of the world’s refineries use technologies licensed by Chevron Lummus Global, where Dr. Krishna was Lead Director from 2002 until his retirement in 2018. He was board member of Catchlight Energy, a Chevron-Weyerhauser JV to convert biomass to fuels, He initiated many renewable fuel projects prior to retirement. Dr. Krishna supervised the team at Chevron’s Richmond Technology Center conceived of the Pascagoula Base Oil Project, designed it, supplied the catalysts and helped startup the plant in 2014. The total project cost was $1.4B, making Chevron a leading producer of long drain cycle lubricant base oils. Dr. Krishna’s organization led the development of a replacement for the use of HF acid in Alkylation, leading to the award-winning “ISOALKY” process, a ten-year project that resulted in the first commercial plant built at Chevron’s Salt Lake refinery, which was commissioned in 2021.

Dr. Steve Sciamanna

Dr. Sciamanna teaches in the Product Development Program, a professional MS degree from the Chemical & Biomolecular Engineering Dept. at UC Berkeley. Dr. Sciamanna serves on the industry merit and peer-review team for the DOE-Advanced Manufacturing Office (AMO) providing a value assessment of the AMO R&D portfolio. Dr. Sciamanna's extensive career at Chevron spanned domestic assignments in R&D, new technology development and deployment and upstream process engineering. Dr. Sciamanna received his B.S. and Ph.D. degrees in Chemical Engineering from the University of California, Berkeley and an M.S. degree from the Massachusetts Institute of Technology (M.I.T.) School of Chemical Engineering Practice.

Dr. Bhavani Raghuraman

Dr. Raghuraman has 35 plus years of R&D experience with expertise in reservoir modeling & optimization, oilfield water chemistry, oilfield fluid sensors and membrane-based separations. She retired as a Scientific Advisor from SLB after a 25-year career during which she held several leadership roles of increasing responsibility in R&D and Technology Commercialization. She is currently VP Technology (Subsurface) for THEMES, working towards commercialization of long duration energy storage technologies to accelerate the transition to clean energy.
