Scoping cost and abatement metrics for biomass with carbon capture and storage — the example of bioCCS in cement

Negative emission technologies such as biomass with carbon capture and storage (bioCCS) may become an important instrument to limit global warming. Currently, estimates of CO2 avoidance cost for bioCCS vary widely. Using a case study of a cement plant, this paper illustrates how this variance is partially attributable to the system boundary...

Negative Emissions in the Industrial Sector

Preventing the worst impacts from the ongoing climate crises requires rapid and dramatic reduction of anthropogenic emissions of greenhouse gases to “net zero”. However, it is highly likely that we will also need to remove greenhouse gases from the atmosphere to compensate for residual and/or historic emissions. In particular, the industrial...

Decarbonising Industry via BECCS: Promising Sectors, Challenges, and Techno-economic Limits of Negative Emissions

Purpose of Review: This paper reviews recent literature on the combined use of bioenergy with carbon capture and storage (BECCS) in the industries of steel, cement, paper, ethanol, and chemicals, focusing on estimates of potential costs and the possibility of achieving “negative emissions”. Recent Findings: Bioethanol is seen as a potential near...

Curing time: a temporally explicit life cycle CO2 accounting of mineralization, bioenergy, and CCS in the concrete sector

The decarbonization of concrete production requires a multi-pronged approach including the abatement of CO2 emissions from cement production as well as storage of CO2 within concrete itself. This study explores the decarbonization potential of combining bioenergy and carbon capture and storage (CCS) during cement production with the accelerated...

Can bioenergy with carbon capture and storage result in carbon negative steel?

This paper explores the potential of achieving negative emissions in steelmaking by introducing bioenergy with carbon capture and storage (BECCS) in multiple steelmaking routes, including blast furnace and HIsarna smelt reduction, and Midrex and ULCORED direct reduction. Process modelling and life cycle assessment were used to estimate CO<sub...

When are negative emissions negative emissions?

Negative emission technologies (NETs) have seen a recent surge of interest in both academic and popular media and have been hailed as both a saviour and false idol of global warming mitigation. Proponents hope NETs can prevent or reverse catastrophic climate change by permanently removing greenhouse gases from the atmosphere. But there is...
