Deploying coal-bioenergy gasification systems with carbon capture and storage (CBECCS) provides a promising opportunity for China to realize its carbon mitigation and air pollution abatement goals simultaneously. The authors conducted a comprehensive assessment of CBECCS technology for China, with a focus on plant and fuel configurations (e.g., biomass ratios) and economics, as well as CO2 and greenhouse gas emissions and cobenefits for air quality.

Societal (In)Security in the Middle East: Radicalism as a Reaction?

| Apr. 24, 2019

Societal insecurity, stemming from historical and functional realities has emboldened the identity-based gap of states vs. societies in the Arab region. The division of the Ottoman Empire into new states without much attention to identity lines, created a historical identity challenge in those states. On the other hand, Arab ruling elites’ efforts to enforce state-centred identities failed to prevent the challenge of conflicting identities. Later on, their functional inefficiencies emboldened the identity dichotomy.

As a result of threats perceived by Arab societies against their collective identity as well as separate challenges facing each state, the state-society gap continues to challenge state identities. Collectively perceived threats create and strengthen collective frameworks intended to address those threats. And among other frameworks come radical and terrorist organisations.

Governments as Partners: The Role of Alliances in U.S. Cleantech Startup Innovation

Accelerating innovation in clean energy technologies is a policy priority for governments around the world aiming to mitigate climate change and to provide affordable energy. Most research has focused on the role of governments financing R&D and steering market demand, but there is a more limited understanding of the role of direct government interactions with startups across all sectors. The authors  propose and evaluate the value-creation mechanisms of network resources from different types of partners for startups, highlighting the unique resources of government partners for cleantech startups.

A Process for Capturing CO2 from the Atmosphere

    Authors:

| 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.

Simultaneous Pursuit of Discovery and Invention in the US Department of Energy

There is a sharp boundary between basic and applied research in the organizational structure of the US Department of Energy (DOE). In this work, the authors consider a branch of DOE that was designed to operate across this boundary: the Advanced Research Projects Agency — Energy (ARPA-E). They hypothesize that much of energy research cannot be neatly categorized as basic or applied and is more productive outside of the confines of the basic/applied dichotomy; ARPA-E provides an opportunity to test that hypothesis.

Six Principles for Public Energy Innovation Programs

As the window of opportunity to avert dangerous climate change closes, the authors argue that we urgently need to take stock of government initiatives that accelerate innovation in energy technologies to reduce greenhouse-gas emissions. What works and why?

Rescue US Energy Innovation

President Trump has proposed severe cuts to US government spending on energy research, development and demonstration, but Congress has the 'power of the purse' and can rescue US energy innovation. If serious cuts are enacted, the pace of innovation will slow, harming the economy, energy security and global environmental quality.

Integrating Uncertainty into Public Energy Research and Development Decisions

| 2017

As the threats of climate change and economic instability loom large, public energy investment can seem like roll of the dice. Now, new research has analyzed scientific publications to identify the "good bets" for governments committed to reducing greenhouse gas emissions even in the face of growing constraints on public R&D budgets.
