The New Age of Energy Infrastructure
The energy transition has led to new investments and projects being announced at a frenetic pace. In our view, energy infrastructure companies will play a significant role in this transition. As business plans progress, companies should be able to re-purpose their existing assets while simultaneously helping to reduce CO2 emissions.
