We have published a new paper in Energy & Environmental Science on an integrated process for producing biofuels using bio-compatible ionic liquid pretreatment and reversible pH-adjustment with CO2.

My collaborators and I have published two new papers this fall. The first is the result of a partnership between the Energy Biosciences Institute and the University of Bath, entitled “Challenge clusters facing LCA in environmental decision-making—what we can learn from biofuels”. It is available in The International Journal of Life Cycle Assessment. The paper is open-access and available for download here. The second paper is the result of work done at Lawrence Berkeley National Lab on spatially-explicit water impacts of carbon capture and sequestration. It is published in Environmental Modeling and Software and available here.
I’m excited to share another paper that combines experimental work on drop-in fuel production from bio-based materials with life-cycle assessment: Upgrading Lignocellulosic Products to Drop-In Biofuels via Dehydrogenative Cross-Coupling and Hydrodeoxygenation Sequence. Sanil Sreekumar is the lead author.
I have posted the pre-publication versions of most of my previous papers on the Publications page of this site. Feel free to download un-typeset copies there or access the final versions on the journals’ websites. If the paper you want is not provided in a free format, please email me to request a copy (email@example.com).
I’m thrilled to share a new paper published in PNAS today entitled “Novel pathways for fuels and lubricants from biomass optimized using life-cycle greenhouse gas assessment”. The paper combines novel experimental results for a variety of pathways converting C5 and C6 sugars to jet fuels and lubricants with life-cycle assessment and optimization to explore how different biorefinery configurations can affect the net GHG emissions. Madhesan Balakrishnan is the lead author.

Our battery end-of-life group has just published a new paper in the Journal of Power Sources on the energy and greenhouse gas implications of using post-consumer electric vehicle batteries for grid-connected stationary energy storage. Roger Sathre is the lead author. Co-authors include Olga Kavvada and Thomas Hendrickson. The paper can be accessed here.
My colleagues and I have published a new paper on the logistics, economics, and environmental tradeoffs of scale-up strategies for automotive Li-ion battery recycling in California. Hendrickson et al (2015) is available in the most recent issue of Environmental Research Letters.
I’m excited to share a couple of new papers, one in Environmental Science & Technology and one in Energy & Environmental Science. The ES&T paper, entitled “The role of lignin in reducing life-cycle carbon emissions, water use, and cost for US cellulosic biofuels” has just been posted in it’s pre-publication “just accepted” format. The other, entitled “Life-cycle net energy assessment of large-scale hydrogen production via photoelectrochemical water splitting” is led by Roger Sathre and was published by EES last month.
My colleagues and I have published a new paper in Environmental Science & Technology entitled “Achieving deep cuts in the carbon intensity of automobile transportation by 2050: Complementary roles for electricity and biofuels”. The manuscript can be downloaded here.
The findings of our paper in Environmental Research Letters, entitled “Lifecycle greenhouse gas implications of US national scenarios for cellulosic ethanol production” are featured in an article by environmentalresearchweb.
