The Biden administration has proposed zeroing out carbon emissions from the electric power industry by 2035. The eventual shuttering of most coal- and gas-fired power plants—once seen as both politically impossible and profoundly irresponsible—now seems all but inevitable. The question is now, how do we replace all that power?

Carbon capture has received a lot of attention as a climate change-fighting tool. If private companies can find a way to make profitable products from captured carbon, then free enterprise will leverage the marketplace toward climate action instead of against it. Proposed uses have been emerging across a vast array of products and materials, whether in new ways to make traditional materials or in entirely new materials and products.

NASA is engaged in a new program to send astronauts back to the lunar surface. Some elements of the new program, called Artemis, will seem like carbon copies of the 1960s roadmap to the Moon. Bu the effort will take advantage of computers, design tools, and materials that are radically more advanced than they were for the Apollo program.

The importance of manufacturing to national security is recognized by defense professionals across the political spectrum. And yet, investments in American manufacturing infrastructure have fallen behind other nations, exacerbating security concerns. As a new administration sets its course for both economic and security policy, there is an opportunity for new investments in infrastructure, education, and research and development to support advanced manufacturing that can enhance the national defense.

Stories of using 3D printing to respond to the pandemic throw a spotlight on additive manufacturing and its potential for fast, flexible production of critically needed parts. Whether it was face shields, nasopharyngeal swabs, or respiratory masks, additive manufacturing rose to the challenge to fill in the gap caused by a disrupted supply chain. Now, some industry observers are starting to ask whether 3D printing could be the future of manufacturing.

To meet the ambitious targets ahead of us, all possible processes and technologies must be considered to ensure end-of-life plastics are not disposed in landfills. Chemical recycling can repurpose used plastics into new products, including new plastics, industrial products, and transportation fuels. In addition to creating new products, these technologies keep these plastic materials circulating within the existing infrastructure and economy.

Large nuclear power plants are becoming increasingly difficult to site and build. The solution, say some nuclear advocates, is to give up on gigawatt-scale, bespoke plants and—following in the footsteps of other energy system—go small and modular. Small modular reactors (SMRs), which would generate tens or a few hundreds of mega-watts, would have a lower price tag and could prove to be safer.
