ExxonMobil marine engine

When ExxonMobil was searching for a research partner to operate a one-of-a-kind experimental engine that would enable the development of next-generation lubricants for the marine industry, one place topped the international oil and gas company’s list

Arctic 2

For the past six years, some 140 scientists from five institutions have traveled to the Arctic Circle and beyond to gather field data as part of the DOE-sponsored Next-Generation Ecosystem Experiments Arctic or NGEE Arctic project. We talk with the project's director, ORNL's Stan Wullschleger, about the discoveries and challenges of the NGEE Arctic project.

The ingredients that make geothermal energy suitable for electricity production are simple: heat, permeability (usually fractured rock) and water. Until recently the trick has been finding all in the same place and in the right amounts.

Enormous heat energy is available between 3 and 10 kilometer...
