Science, Technology, and Public Policy

On December 3, 2022, Nicola De Blasio, Senior Fellow with the Belfer Center’s Environment and Natural Resources Program (ENRP), chaired a panel discussion, “Is Hydrogen Our Future?,” at the Rome MED – Mediterranean Dialogue (Rome MED), an annual high-level conference on Mediterranean geopolitics. The panel discussion was part of ENRP’s Future of Hydrogen project’s ongoing engagement with global policymakers, who are increasingly viewing hydrogen as a solution to meeting their decarbonization and energy security goals. 

David M. Allison argues that in ascending order of predictive power, warnings of an imminent nuclear strike would come from Russian whistleblowers, the U.S. intelligence community, and Putin himself.

This paper focuses on the market and geopolitical implications of renewable hydrogen adoption at scale in the European Union (EU). The authors analyze long-term strategies based on three reference scenarios in which the EU prioritizes a different strategic variable: energy independence, cost (optimization), or energy security. Developing competitive and secure hydrogen markets will require close coordination between policy, technology, capital, and society—and for EU countries to unite behind a shared long-term vision.

Joseph Nye argues that prudence results from the fear of creating unintended consequences in unpredictable systems and can develop into a norm of nonuse or limited use of certain weapons or a norm of limiting targets. Something like this happened with nuclear weapons when the superpowers came close to the brink of nuclear war in 1962, during the Cuban missile crisis. The Limited Test Ban Treaty followed a year later.

The Biden-Putin summit in Geneva did not disappoint the very low expectations set out for it. To move beyond symbolism and signaling, however, the Biden-Putin proclamation has to be translated into practical progress.

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

The nuclear arms control architecture that underwrites European security is crumbling. Europe cannot achieve global nuclear disarmament or build its own credible deterrent, but it can clear the path for the next generation of arms governance through joint action. 

Rebecca Davis Gibbons writes that having a full appreciation of the consequences of nuclear weapons and their place in society means learning from the stories of the survivors of Hiroshima and Nagasaki—but also from the stories from other survivors of nuclear explosions: those who lived and worked adjacent to testing sites in Algeria, French Polynesia, Australia, the United States, France, the Republic of the Marshall Islands, Western China, and Kazakhstan.

Polls in the United States and nine allied countries in Europe and Asia show that public support for a nuclear test is very low. If the Trump administration conducts a test, then it shouldn't expect backing from Americans or its closest U.S. partners.

The authors argue that more determined efforts to globalize renewable energy transmission can confer significantly higher economic and environmental benefits from renewables on billions of people. This can be done by exploiting spatial differences between electricity loads and net renewable generation across time zones (temporal arbitrage) and latitude (seasonal arbitrage). Using very long distance, ultra-high voltage (UHV) transmission infrastructure, temporal and spatial arbitrage can move low-cost clean electricity from areas with excess capacity to high demand zones in other countries and even continents.
