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. 

"One of the last ties of an economically declining Russia to Western Europe, Nord Stream must become part of a broader transatlantic strategy which combines shorter-term policy goals to deal with Moscow’s aggressive behavior and a longer-term effort to keep a door open for a more cooperative relationship”

A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network.

In this report, the authors conduct a benchmarking analysis for energy and CO2 emissions intensity of the steel industry among the largest steel-producing countries.

Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. The goal of this study is to develop a roadmap for decarbonization of California's cement and concrete production. In this study, the authors look at the current status of cement and concrete production in California and develop scenarios up to 2040 to analyze different decarbonization levers that can help to reduce CO2 emissions of cement and concrete production in California.

After many years of productive service, industrial plants reach the end of their useful life and must be dismantled. This complex and costly process, know as decommissioning (commissioning refers to the beginning of a plant useful life), is a confluence of economic, environmental, physical, and regulatory challenges.

Miscalculation is unlikely when open conflict would come with high costs for both countries, costs that neither their leaders nor their publics are willing to accept.
