Overview

Hitachi has worked on specific solutions for the reduction of CO₂ emissions in the oil and gas field by utilizing energy-saving technologies for rotating machinery. In particular, switching existing steam turbine drive equipment to electric drive has achieved a significant reduction in CO₂ emissions. Some implementation-related considerations apply when converting rotating machinery to electric drive, such as how to deal with resonance and higher harmonics. Hitachi has made efforts to meet these challenges, drawing upon its strength in analysis based on prior simulations and verification technologies.
