Bay Journal: Biochar could be the hot new thing in addressing Bay’s poultry litter

"West Virginia farmer Josh Frye raises chickens for a meat processor and sells most of their manure to nearby crop growers for use as fertilizer. But what he does with the rest of the manure could help tackle two big environmental problems: cutting back nutrient pollution in the Chesapeake Bay and reducing carbon emissions that accelerate global warming."

Vimeo: ‘Dirt Rich’ — The Importance of Biochar and Regenerative Systems for Soil Health

"Dirt Rich shifts focus from greenhouse gas emissions to carbon drawdown which is the only viable solution for reversing the effects of runaway global warming in a timely manner. Through exploration of geo-therapy strategies, Dirt Rich shines a light on their value and beauty which undeniably are our last hope for protecting life as we know it on this challenged planet. Through regenerative agricultural practices, reforestation of abandoned land, protection/restoration of carbon-rich wetlands and keystone species, Dirt Rich illustrates how implementing these strategies will return our atmosphere to safe levels of carbon while growing soil, our most precious resource."

Horizon: Recharging soils with carbon could make farms more productive

"Turning crop waste and discarded paper into a material called biochar could help to capture carbon from the atmosphere and store it in the soil while also helping to enrich farmland."

Schmidt, H.; et al. (2018): Pyrogenic carbon capture and storage

Schmidt, H.; Anca-Couce, A.; Hagemann, N.; Werner, C.; Gerten, D.; Lucht, W.; Kammann, C. (2018): Pyrogenic carbon capture and storage. In: GCB Bioenergy 38 (1), S. 215. DOI: 10.1111/gcbb.12553.

"During the last decade, biochar has been discussed as a promising option to improve soil fertility and sequester carbon, although the carbon efficiency of the thermal conversion of biomass into biochar is in the range of 30%–50% only. So far, the liquid and gaseous pyrolysis products were mainly considered for combustion, though they can equally be processed into recalcitrant forms suitable for carbon sequestration. In this review, we show that pyrolytic carbon capture and storage (PyCCS) can aspire for carbon sequestration efficiencies of >70%, which is shown to be an important threshold to allow PyCCS to become a relevant negative emission technology."

E&E News: Moniz group launches 'substantial' CO2 air capture project

"The Energy Futures Initiative's air-capture project aims to bring new focus and dollars to an idea that proponents say is necessary to hit long-term climate targets. Supporters say carbon-removal strategies are an important step toward decarbonizing the energy sector by the end of the century."

Werner, Constanze; et al. (2018): Biogeochemical potential of biomass pyrolysis systems for limiting global warming to 1.5 °C

Werner, Constanze; Schmidt, H-P; Gerten, Dieter; Lucht, Wolfgang; Kammann, C. (2018): Biogeochemical potential of biomass pyrolysis systems for limiting global warming to 1.5 °C. In Environ. Res. Lett. 13 (4), p. 44036. DOI: 10.1088/1748-9326/aabb0e.

"Negative emission (NE) technologies are recognized to play an increasingly relevant role in strategies limiting mean global warming to 1.5 °C as specified in the Paris Agreement. The potentially significant contribution of pyrogenic carbon capture and storage (PyCCS) is, however, highly underrepresented in the discussion. In this study, we conduct the first quantitative assessment of the global potential of PyCCS as a NE technology based on biomass plantations. Using a process-based biosphere model, we calculate the land use change required to reach specific climate mitigation goals while observing biodiversity protection guardrails. We consider NE targets of 100–300 GtC following socioeconomic pathways consistent with a mean global warming of 1.5 °C as well as the option of additional carbon balancing required in case of failure or delay of decarbonization measures."

Tan, Raymond R.; et al. (2018): Graphical Pinch Analysis for Planning Biochar-Based Carbon Management Networks

Tan, Raymond R.; Bandyopadhyay, Santanu; Foo, Dominic C. Y. (2018): Graphical Pinch Analysis for Planning Biochar-Based Carbon Management Networks. In Process Integr Optim Sustain 18 (5), p. 1457. DOI: 10.1007/s41660-018-0033-6.

"Biochar is a potentially scalable negative emission technology (NET). The negative net flow of carbon is achieved sequentially via photosynthesis which fixes atmospheric carbon into biomass, followed by thermochemical processing of biomass into biochar which converts the bulk of the fixed carbon into stable or recalcitrant form, and finally by the application of the resulting biochar to soil. In addition, this process can result in additional carbon offsets through favorable modification of soil by reducing fertilizer requirement, as well as other secondary benefits. On the other hand, biochar is typically contaminated with traces of organic (e.g., dioxins) and inorganic impurities (e.g., salts) that are detrimental to soil quality."

New Carbon Economy Consortium (2017): Building Research Programs to Support 21st Century Economic Opportunity

New Carbon Economy Consortium (2017): Building Research Programs to Support 21st Century Economic Opportunity. Arizona State University. Tempe.

"Now is the time to map paths to the breakthrough research programs and forward-looking university-business partnerships that will serve as the hubs for this new carbon economy. This is an economy in which low-carbon industry and primary energy production are joined by industrial centers, agricultural regions and food-producing ecosystems that turn excess CO2 into consumer goods, fuels, building materials and fertile soil. With deliberate but ambitious planning, the United States and collaborators in other countries can develop the knowledge, technologies and human capital to catalyze the new carbon economy by 2040."

Fidel, Rivka B.; et al. (2017): Impact of Biochar Organic and Inorganic Carbon on Soil CO2 and N2O Emissions

Fidel, Rivka B.; Laird, David A.; Parkin, Timothy B. (2017): Impact of Biochar Organic and Inorganic Carbon on Soil CO2 and N2O Emissions. In: Journal of environmental quality. DOI: 10.2134/jeq2016.09.0369.

"Here we therefore aim to assess biochar organic and inorganic C pool impacts on CO2 and N2O emissions from soil amended with two untreated biochars, inorganic carbon (as Na2CO3), acid (HCl) and bicarbonate (NaHCO3) extracts of the biochars, and acid and bicarbonate/acid-washed biochars during a 140-d soil incubation. We hypothesized that (i) both biochar labile organic carbon (LOC) and inorganic carbon (IC) pools contribute significantly to short-term (<1 mo) CO2 emissions from biochar-amended soil, (ii) biochars will influence the size of soil NH4+ and NO3 pools, and (iii) changes in soil inorganic N pools will affect soil N2O emissions."
