Sub-Sea CO2 Storage Leakage Studied (Ind. Report)
Carbon Storage
Date: 2019-05-15
Researchers at GEOMAR Helmholtz Centre for Ocean Research Kiel investigating the possibilities and limits of the sub-sea CO2 storage report it is possible to reduce anthropogenic CO2 emissions by separating CO2 from flue gases and storing the captured CO2 in geological formations. The researchers also note negative emissions can be achieved by coupling biogas production with CO2 separation and storage.

Assessments by the IPCC show that these approaches are essential parts of the technology mix needed to limit global warming to less than 2 degrees C.

In Europe the largest potential to store CO2 is located offshore in deep saline aquifers and other sub-seabed geological formations of the North Sea where over 10,000 oil and gas wells have been drilled. At many of these wells, methane gas from shallow biogenic deposits is leaking into the environment because the surrounding sediments were mechanically disturbed and weakened during the drilling process. The study notes that CO2 stored in the vicinity of these wells may leak and ultimately return into the atmosphere.

"We have performed a release experiment in the Norwegian sector of the North Sea to determine the footprint and consequences of such a leak", explains study lead author Dr. Lisa Vielstadte from GEOMAR Helmholtz Centre for Ocean Research Kiel.

In the study, CO2 released at the seabed in 82 meters of water was tracked and traced using a remotely operated vehicle (ROV) equipped with chemical and acoustic sensors and additional measurements on board of Research Vessel Celtic Explorer. The resulting data showed that CO2 gas bubbles were completely dissolved close to the seafloor and the pH value of ambient bottom waters was lowered from a background value of 8.0 to a more acidic value of 7.0 at the release site as a consequence of the dissolution process. This bottom water acidification has detrimental effects on organisms living at the seabed", However, strong bottom currents induced a rapid dispersion of the dissolved CO2 such that the area at the seabed where potentially harmful effects can occur is small.

Accordingly, the study tentatively concluded it is possible to store CO2 safely in sub-seabed formations if the storage site is located in an area with a small number of leaky wells, the report summarizes.

Mercurius Biorefinery Slated for Queensland, Australia (Int'l)
Mercurius
Date: 2019-02-20
In the Land Down Under, the Queensland State government reports it has given the nod and has funded a biorefinery pilot plant in Gladstone. The 3-month pilot biorefinery will be the trail site for jet fuel and diesel production from agricultural and forestry waste. Construction is due to begin this month and will be carried out by Bellinham, Washington-based Mercurius Biofuels LLC.

Depending on the pilots success, Mercurius plans to construct a larger demonstration plant, which would scale up production of biofuels and bio-chemicals, according to a company statement.

Mercurius Biorefining is developing its novel REACH process, which converts cellulosic biomass to hydrocarbons in the renewable diesel, aviation, and marine fuel ranges. Valuable by-products include bio-char and a bio-plastic monomer, FDCA.

REACH (Renewable Acid-hydrolysis Condensation Hydrotreating) is a novel application of proven technologies which is both feedstock- and product-flexible. Sources of potential feedstock include waste from municipalities (e.g. biogenic portion of MSW), forestry and agriculture.

Biomass Eclipsed by Solar as US Power Source (Ind. Report)
US Energy Information Agency
Date: 2018-07-11
According to the US Energy Information Agency (EIA) Preliminary Monthly Electric Generator Inventory, U.S. electric power generation from solar resources reached 77 million MWh in 2017, surpassing for the first time annual generation from biomass resources, which generated 64 million MWh in 2017. Among renewable sources, only hydro and wind generated more electricity in 2017, at 300 million MWh and 254 million MWh, respectively.

EIA data also shows that while biomass generating capacity has remained relatively unchanged in recent years, solar generating capacity has consistently grown. In 2017, December solar capacity additions accounted for 21 pct of the annual total.

Biomass electricity generation comes from multiple fuel sources which in 2017 had the following make-up of the 64 million MWh generated: wood solids 68 pct; landfill gas 17 pct; municipal solid waste 11 pct; and other biogenic and nonbiogenic materials 4 pct.

UBC Researchers Touting Biogenic Solar Cells (New Prod & Tech)
UBC
Date: 2018-07-09
Researchers at the University of British Columbia (UBC) are reporting the development of a bacteria-powered -- biogenic -- solar cell that worked equally well in dim and bright sun light. The researchers generated a current density of 0.686 milliamps per sq cm, compared to 0.362 achieved by others in this field.

Previous efforts to create biogenic solar cells have focused on extracting the natural dye that bacteria use for photosynthesis, which is a costly and complex process that involves toxic solvents. UBC researchers left the dye in the bacteria, coated the bacteria with a mineral that could act as a semiconductor and applied the mixture to a glass surface. They genetically engineered E. coli to produce large amounts of lycopene, a dye effective at harvesting light for energy conversion, according to UBC.
