Newsweek spoke with Evelyn Wang, the head of the Department of Energy's ARPA-E, about new innovations toward clean energy and reducing carbon emissions.
As the planet heats up and catastrophic extreme weather events continue to increase, the search for new solutions to the climate crisis is growing ever more urgent. Few people are better positioned to find and nurture transformative new approaches than Evelyn Wang, who in January was sworn in as the new director of the the Advanced Research Projects Agency–Energy .
We like to think of our agency as taking many shots on goal. We want to give policymakers options, and support technologies that will actually move the needle—pushing various sectors within the energy and climate space towards solutions that can work. One way to do that is to think about the key bottlenecks preventing solutions from taking root and then identify technological innovations that can help mitigate those bottlenecks.
Industrial decarbonization is another really big area that is also very important to us. Cement production, for instance, contributes to close to 10 percent of greenhouse gas emissions because it's so carbon intensive. We've been supporting various efforts to think about other ways to produce cement that is not so carbon-intensive and can even reach net-zero emissions.
DARPA has famously taken credit for GPS and the Internet, among other things. What are some of the biggest successes that have come out of ARPA-E? We've talked mainly about technologies to reduce emissions. Are we also going to need to find ways to remove CO2 from the atmosphere?
