Uncovering the Domestic Factor in the Sino-Russian Energy Partnership

| Oct. 15, 2018

The article outlines the role of national narratives in driving both Russia and China’s energy foreign policy and goes on to argue that the Sino-Russian gas breakthrough in 2014 was due to the peculiar way in which domestic factors paired with international circumstances to produce the outcome at that particular moment.

Both energy production and consumption can simultaneously affect regional air quality, local water stress and the global climate. Identifying the air quality–carbon–water interactions due to both energy sources and end-uses is important for capturing potential co-benefits while avoiding unintended consequences when designing sustainable energy transition pathways. The authors examine the air quality–carbon–water interdependencies of China's six major natural gas sources and three end-use gas-for-coal substitution strategies in 2020.

Harvard-Tsinghua Workshop on Low-Carbon Development and Public Policy

| September 2018

The Belfer Center’s Environment and Natural Resources Program and the Center for Science, Technology, and Education Policy at Tsinghua University held the fifth annual Tsinghua-Harvard Workshop on Low-Carbon Development and Public Policy. This event brought together leading experts on climate and energy from academic, business, and government communities in both the United States and China. This year’s workshop focused on electricity systems and renewable energy penetration.

The Collapse of Civilizations

| September 2018

Five causes of collapse appear paramount: major episodes of climate change, crises-induced mass migrations, pandemics, dramatic advances in methods of warfare and transport, and human failings in crises including societal lack of resilience and the madness, incompetence, cultic focus, or ignorance of rulers.

An Economic Anatomy of Optimal Climate Policy

| August 2018

The authors introduce geoengineering into an optimal control model of climate economics. Together with mitigation and adaptation, carbon and solar geoengineering span all possible climate policies. Their wildly different characteristics have important implications for policy. They show in the context of their model that: (i) whether emissions are positive or zero the optimal carbon tax always equals the marginal cost of carbon geoengineering; (ii) the introduction of either form of geoengineering leads to higher emissions yet lower temperatures; (iii) in a world with above-optimal cumulative emissions, mitigation alone is insufficient and only a complete set of instruments can minimize climate damages.

This is an updated version of a paper first published in July 2017.

A Process for Capturing CO2 from the Atmosphere

    Authors:
  • Geoffrey Holmes
  • David St. Angelo
  • Kenton Heidel
| 2018

The authors describe a process for capturing CO2 from the atmosphere in an industrial plant. The design captures ∼1 Mt-CO2/year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. They describe the design rationale, summarize performance of the major unit operations, and provide a capital cost breakdown developed with an independent consulting engineering firm. They report results from a pilot plant that provides data on performance of the major unit operations.
