I missed Andrew's email on these Senate Amendments when he first posted it.


The Manchin Amendment (s. amdt. 3270) is deeply flawed in that its 
specification for the biomass energy input for "net-negative" projects does not 
require the biomass to be produced in a manner that is net-zero in carbon 
emissions.  The relevant text is--


 ``(C) through which each use of coal will be combined with the use of a 
regionally indigenous form of biomass energy, provided on a renewable basis, 
that is sufficient in quantity to allow for net-negative emissions of carbon 
dioxide (in combination with a carbon capture system), while avoiding impacts 
on food production activities."

As can be seen, the text requires only that the biomass be "regionally 
indigenous," "provided    on a renewable basis," and avoid "impacts on food 
production activities."

These conditions of course do not require that the supplied biomass achieves a 
net increase in  removals sufficient to cover the emissions resulting from its 
production, transport and                 combustion.  This defect was brought 
to the attention of the sponsors, who declined to fix the  problem.

The refusal of legislators to insist on adequate specifications for biomass, if 
continued, will be a major barrier to responsible exploration of biomass energy 
systems.

1.   This is to comment on the news release from the Berkeley “Center for 
Carbon Renewal”  sent 5 days ago by Andrew, which started this way:

Senate Widens Scope of Energy Bill to Include Carbon-Negative Technologies

2.  But it is easiest to comment on the full release, which is only four 
paragraphs.


a.     “BERKELEY (May 4, 2016) — The Senate recently passed two amendments to 
support the development of carbon removal solutions in the Senate’s Bipartisan 
Energy Bill: S.2012 - The Energy Policy Modernization Act of 2016. The 
amendments focus on two carbon-negative energy technologies: bioenergy with 
carbon capture and storage and direct air capture and sequestration. According 
to Noah Deich, Executive Director of Center for Carbon Removal, “These 
amendments are an important recognition from the Senate on the need for 
negative emissions technologies to build a strong and secure domestic energy 
industry that is compatible with our climate goals.”

[RWLa:   My reading of the amendments are that they are, unfortunately, not 
primarily NETs.  I wish they were.   How do we get more real CDR/NET funding 
legislation?


b.  “Amendment S.3270, sponsored by Senator Joe Manchin (D-WV), calls for the 
creation of a “net- negative carbon dioxide emissions project” under the Coal 
Technology Program. This project would employ the co-conversion of coal and 
biomass fuels coupled with carbon capture and storage or utilization to produce 
net-removal of carbon dioxide from the atmosphere. Postdoctoral research 
scientist at the Carnegie Institution for Science, Daniel L. Sanchez, commented 
on the amendment’s role in fostering technology innovation and 
commercialization: “Near-term, large-scale, thermochemical co-conversion 
projects with carbon capture and storage can demonstrate technical feasibility 
and reduce investment risks, ultimately enabling gigaton-scale CO2 removal.”

[RWLb:   The amendment language and funding levels show this is a coal subsidy, 
but I concur we should be pleased that BECCS is in here at all.

My question (for anyone) is whether biochar proponents might have any chance in 
proposing a pre-BECCS biochar component under this legislation.  That is - the 
input biomass can be pyrolyzed rather than combusted,  with the resulting 
biochar providing out-year CDR and economic benefits not possible with BECCS. 
The pyrolysis gases (but no solids) would be combined with the coal and 
(presumably) result in about half as much electricity per unit in-coming 
biomass.  The BECCS operation still captures, liquifies and places (combined 
fossil and biomass) CO2 deep underground,  but now about half as much CO2 from 
the biomass because char is being produced.  The coal companies should be 
delighted as the missing carbon that has emerged as biochar must be made up 
with coal.  Yet there should be more total NET/CDR because of the out-year 
benefits of the biochar.

This helps biochar’s argument as “all” (rather than half) of the biomass’ 
carbon is sequestered.  This helps the BECCS argument because of the long-term 
soil and NPP improvements that the biochar provides.  I have not seen this 
combined biochar/BECCS concept in print - except possibly by me somewhere 
earlier.  Anyone seen this hybrid before?  It could fly if the fundamental 
source is coal and CCS, where I am claiming costing should be improved.  For 
strictly biomass comparisons, I fear the extra costs of the BECCS component may 
not be justified. I know of lots of biochar deployment - but none with a BECCS 
aspect.   We need more comparative economic analyses between BECCS and biochar.


c.     ”Amendment, S.3017, sponsored by Senators John Barrasso (R-WY) and Brian 
Schatz (D-HI), creates a prize managed by the Secretary of Energy to encourage 
the development of direct air capture systems by including “a financial award 
for the separation of carbon dioxide from dilute sources”. “Direct air capture 
is a vital technology for preventing climate change and ensuring that any 
emission can be canceled. A technology prize, like the one proposed in the 
Senate bipartisan energy bill, will aid these technologies in reaching cost and 
scale,” said Klaus Lackner of the Arizona State University Center for Negative 
Carbon Emissions on the amendment.”

[RWLc:  This language seems not to require CDR - since the Lackner/DAC emphasis 
seems (for cost reasons) to now be more on creating fuels - not on CDR/NET.   
The connection to biochar (and BECCS) is that it should be much cheaper to 
capture the high density CO2 release from a power plant.  As with BECCS, 
biochar benefits from anyone finding a way to use the waste CO2 productively.  
So producing fuels from biochar’s waste/vented CO2 stream sounds well worth 
investigating.  Biochar producers have a lot of hot CO2 to give away;  BECCS 
producers won’t.


d.       ”Dr. Daniel Kammen, professor at UC Berkeley and director of the 
Renewable and Appropriate Energy Laboratory, as well as Science Envoy for the 
U. S. State Department spoke on both amendments, saying, “Natural ecosystems 
are the best means to sequester carbon, so investments in healthy forests, 
oceans, and sustainable agriculture should be at the top of the carbon-negative 
agenda. Moving forward the Senate bill incentivizes governments and firms who 
must commit to research, development and demonstration of ecologically sound 
carbon removal technologies."

    [RWLd:  None of Professor Kammen’s remarks (re “natural”, “forests", 
"sustainable agriculture") apply to BECCS or DAC.  They do apply to biochar.]
