Review of co-processing of biocrudes in oil refineries

Green Car Congress

In an open-access paper in the journal Energy & Fuels, a team from VTT Technical Research Center of Finland, with colleagues from Pacific Northwest National Laboratory (PNNL) and Ghent University, provides an overview of co-processing options for such bio-liquids. The biocrude is more viscous but less dense than FPBO.

As Tesla waits for Giga Berlin’s final approval, critics reiterate water supply concerns

Teslarati

With the massive factory still awaiting its final approval, some of Giga Berlin’s critics have reiterated concerns about the electric vehicle factory’s water consumption. Elon Musk has been asked about Giga Berlin’s water consumption in the past. The factory just is not a very intense consumer of water per square meter. “The

Researchers design nanoparticles for cost-effective hydrogen production process

Green Car Congress

Researchers at the University of Arkansas, with colleagues from Brookhaven National Lab and Argonne National Lab, have found that nanoparticles composed of nickel and iron are more effective and efficient than other more costly materials when used as catalysts in the production of hydrogen fuel through water electrolysis.

Study finds perennial biofuel crops’ water consumption similar to corn

Green Car Congress

Evapotranspiration (ET) refers to the sum total of water lost while the plant is growing, either from evaporation through the plant stem itself (a process called “transpiration”), or from water evaporated off of the plant’s leaves or the ground. —Hamilton et al.

Berkeley researchers propose salted biomass as scalable, economical and stable carbon capture and storage solution

Green Car Congress

Researchers from the University of California, Berkeley, are proposing burying salted biomass in a dry environment within an engineered biolandfill as a solution to sequester carbon that has been photosynthetically fixed by cultivated plants. This is measured by “water activity,” a quantity similar to relative humidity.

Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Maize and other annual crops are easier to manage with traditional farming, but they are tougher on the environment. The researchers conducted ecosystem-scale comparisons of carbon, nitrogen, water, and energy fluxes of Sorghum bicolor with maize and Miscanthus x. Energy sorghum falls somewhere in between.
