At the conclusion of MIT’s 10th annual Energy Conference, panelist Cheryl Martin, director of the US Department of Energy’s ARPA-E research program, declared, “There is no more important issue than energy.”
Urging students to work to supply sufficient energy for a growing population while reducing emissions, Martin added, “It needs every discipline to be in the game.”
The student-run event, held this year on February 27–28, was founded by David Danielson PhD ’08, then an MIT graduate student and now the US assistant secretary of energy and director of the Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy. Danielson, who also founded MIT’s Energy Club—now the Institute’s largest student group—returned to campus both as a keynote speaker and as moderator of the final panel discussion at this year’s conference.
“The last 10 years have been a wild ride in energy,” Danielson said, reflecting on dramatic and unexpected changes including the shale-gas boom, the rise of extreme weather events, and a steep drop in the costs of solar and wind power.
Danielson observed that MIT’s long history of cross-disciplinary research has been especially relevant to energy and combating climate change. “This interdisciplinary culture is a critical element,” he said. “The divisions really blur.”
Danielson also reflected on how far the Institute has progressed in energy research and education. When he arrived on campus, in 2001, as a student interested in solar power, he was astonished to find only one course in that field, and no energy-related student organization. Now MIT has dozens of researchers working in the solar arena; and the Energy Club has more than 5,000 student, faculty, staff, and alumni members and organizes more than 100 events every year. Danielson also pointed out that five of the club’s past presidents are now working at DOE.
And MIT research is having a real impact, he added: Among the 17 initial advanced research projects that DOE funded when Danielson started working there, one was by Donald Sadoway, the John F. Elliott Professor of Materials Chemistry, to produce a low-cost liquid battery for utility-scale storage. While this “phenomenal idea” was first seen as risky and speculative, it has now led to the creation of a company that has raised $50 million and will be installing its first grid-scale batteries this year.
Robert Armstrong, the Chevron Professor of Chemical Engineering and director of the MIT Energy Initiative, kicked off the conference by summarizing a dual challenge: On the one hand, he said, the world is expected to need to double its energy supply by 2050, thanks to a combination of population growth and rising standards of living in developing nations. At the same time, there is a need for drastically reduced emissions from present energy-supply systems, which are still mostly based on fossil fuels. “How do you double the output and still reduce carbon emissions?” Armstrong asked.
He suggested five broad areas that could contribute: a major growth in cheap, reliable solar energy; better methods for storing energy; improvements in the adaptability and reliability of the electric grid; increased use of nuclear energy; and the development of affordable and dependable carbon capture and sequestration systems.
Other keynote speakers at the conference were Thomas Siebel, founder and CEO of C3 Energy; William Colton, vice president for strategic planning at ExxonMobil; Ahmad Chatila, president and CEO of SunEdison; Dirk Smit, vice president of exploration technology research and development at Shell Oil; and William von Hoene Jr., chief strategy officer of Exelon Corporation.
