Terrestrial bioenergy feedstock crops such as switchgrass, canola and corn have lower environmental lifecycle impacts than algae in energy use, greenhouse gas emissions, and water regardless of cultivation location, according to a new lifecycle assessment by researchers at the University of Virginia. 0.4 ± 0.05. 1.8 ± 0.58. 3.3 ± 0.86.

Members of the Marine Algae Industrialization Consortium (MAGIC), led by Duke University in North Carolina, have published an open-access paper in the journal Oceanography presenting the large-scale industrial cultivation of marine microalgae (ICMM) as an answer to pressing global energy, food and climate security issues.

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. By comparison, oil shale has NERs (or EROI) of 1.6−2.0 —Nduagu & Gates. Credit: ACS, Nduagu & Gates.

The metabolism of a city can be interpreted either primarily in terms of energy flows or more broadly including a city’s flows of water, materials, and nutrients. They calculated emissions for ten cities (or metropolitan regions), which vary in population from 432,000 to 9,519,000; comparisons are in per capita terms. Charles Kolb.

This would increase the annual carbon emission to somewhere between 380 and 920 Mt CO 2 e by 2020 depending on water management practices and the extent of plantations. Despite increasing awareness of climate change in that period, the rate of peat destruction was higher in this last 3 year period than ever before. Chris Malins.

Researchers at George Washington University led by Dr. Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). —Licht (2017). 2017.02.005.

Converting oil shale to gasoline via the Alberta Taciuk Processor (ATP)—an above-ground shale retort—results in fuel-cycle greenhouse gas emissions of ~130-150 g CO 2 equivalent/MJ of gasoline produced, according to a new analysis by Dr. Adam Brandt at Stanford University. These emissions are 1.5 Refining of upgraded shale oil. Credit: ACS.

The only by products are water and a fair degree of heat, the latter indicating a degree of inefficiency and wasted energy. Second, while hydrogen can be otherwise produced through the electrolysis of water, this process requires huge amounts of clean and fresh water – a vital and highly valuable commodity of life that can’t be wasted.

Chemists from the University of Glasgow (Scotland) have developed a new method for hydrogen production that is 30 times faster than current state-of-the-art proton exchange membrane electrolyzers at equivalent platinum loading. Hence, if the energy source is renewable, H 2 can be produced sustainably from water using electrolysis.

Southern Cities See Record Temperatures, Little Water. Buckled train tracks and sagging power lines interrupted much of the city’s passenger train service, and residents were advised to conserve water. We’ve seen blackouts, disruptions to many of our transport systems, greater water consumption and of course, more sleepless nights.”

There is no liquid water in a HTPEM MEA and therefore there is no need for a compressor. In comparison, low temperature PEM cells normally can tolerate less than 30ppm CO and less than 1 ppm of sulfur. No compressor. This further reduces system complexity, cost and noise level while greatly increasing fuel cell system efficiency.
