Learning How To Roll Back Climate Change By Unlocking Negative Emissions

The U.S. Capitol Building Complex and thousands of other facilities - hospitals, etc., can join in removing Climate Change from the air while saving on their energy bills! 
NOTE: The plant described on this page is an educational demonstration-sized plant. Having said that, it removes enough Climate Change from the air to be worth it's salt.  Utility-sized plants large enough to actually do the complete job of removing enough Climate Change from the air can be found here.

2021: The Time Has Come To 'Green' The United States Capitol Complex

What Congress can do to demonstrate to the World
The United States has emerged from a Time Of Environmental Darkness.

The U.S. Capitol Complex in Washington, D.C., could become the world's first national Capitol to show working/teaching examples of:


The U.S. Capitol's Power Plant Can Demonstrate Either Or Both Steps For Reducing Climate Change
(NOTE: The following suggestions take advantage of the chemistry of wood.  Half the weight of wood is the element carbon the tree removed from the air to make its branches.)

       The Two Key Steps For Rolling Back Climate Change:        

Ending Climate Change is a Two-Step Endeavor.                                                 Unlocking Carbon Emission's Negative Impact on Air.

Step 1:  Net-Zero.  Stop adding additional Global Warming CO2 to the air.                Step 2:  Repairing the Air.  Suck back existing Global Warming CO2 from the air.      

(Global warming doesn't stop if the CO2 blanket remains in place.    At full effort, much of the "Carbon Neutral" phase would be electrically realized (i.e. switching to electric cars, etc. ) as part of the "Carbon Negative" phase.)

Getting our energy economy on track for zero emissions by adding wood pellet burning carbon-capturing equipment to the Combined Heat and Power (CHP) power plants of our building complexes.
Over 15,000 large building complexes worldwide - Colleges, Military Bases, Hospitals, Apartments, Office Complexes, Large Manufacturing, Airports, plus dozens of other types of building complexes - are major contributors to global Climate Change. 

Summary of what the Capitol's management has recently done:
"The Architect of the Capitol (AOC) is pursuing installation of a combined heat and power (CHP) plant through a Utility Energy Services Contract (UESC) at the nation's Capitol Power Plant. The CHP project includes two 8 MegaWatt (MW) combustion turbines (typically about 10,000 tons CO2 per year per unit), a 1.5 MW steam turbine, and two duct-fired heat recovery steam generators (HRSG) (CO2 emissions typically included as part of the 8 MW combustion turbines), meeting the majority of the steam load required to heat the Capital Building, National Archives and other government facilities in the heart of Washington, D.C.  Additionally, the project will allow the AOC to meet Boiler MACT requirements and provide a plant system efficiency in excess of 75 percent."  * About Steam Heating & Cooling systems:  


U.S. Capitol Building Complex (Campus) in Metropolitan Washington, D.C.      Where we can bury Climate Change CO2?      The Architect of the Capitol selected a Combined Heat and Power (CHP) system to power the Capitol.

Step 1a:
Use Synthetic Natural Gas Made From BioEnergy (Wood) Fuels to Stop Making More Global Warming CO

HOW?   Relatively Simple:   Karlsruhe Institute of Technology (KIT) press release pdf, Sept. 11, 2018:  Production of Renewable Gas from Waste Wood   (Check Out Their Important Links)

Adding a carbon-neutral fuel (in this case, wood) to a pair of natural gas burning industrial combustion jet turbines equipped with heat capturing boilers to provide both heat and electricity to a building complex.
This creates a "Carbon-neutral" facility that does not add to Climate Change emissions because the synthetic gas's carbon was previously removed from the air by the wood pellets.

By powering the U.S. Capitol Building Complex with synthetic natural gas made from wood pellets, ( Biomass-To-Gas pdf ) the stack emissions would become "CO2-neutral" (i.e., Green) and would not add to the world's Climate Change burden.
No other country's capitol could make that claim unless they did the same thing.
Several European countries are working to develop synthetic natural gas technology.
It shouldn't be too expensive to add synthetic natural gas made from wood to any building complex that is already set up with combined heat and power like the U.S. Capitol.

This is not a trivial thing. Everyone pays attention to what the power centers of the world are advocating and demonstrating.


Or, Step 1b:
Use Carbon Captured Fossil Fuels (Coal, Oil, Natural Gas) to Stop Making More Global Warming CO


Above: Fossil-Fuel Carbon Capture.  This equipment represents the best Carbon Capture Technology the world will be able to implement for perhaps the next 10 years.

Worldwide, perhaps 15,000 thousand large building complexes such as colleges and universities, hospitals, factories, airport terminals, military bases, industrial and business centers have central power plants like the U.S. Capitol Building Complex.  Combined, these thousands of large building complexes are major contributors to global Climate Change and many could be modified to "Repair the Air" like the U.S. Capitol Building Complex.

Large companies like Microsoft, IBM, and Amazon are beginning to make commitments to become "Carbon-Neutral" by some time in the near future such as 2030 or 2040.  No reason the Government shouldn't clean up it's operations.

This is the direction the troops are marching. 

The time has come for the Capitol Building Complex, which began marching in this direction in 2007, resumed leading the world.


BioEnergy with Carbon Capture and Storage (BECCS) Overview

BECCS is one of the few technologies that is capable of removing past CO2 emissions remaining in the atmosphere. As this enhances the 'when' (i.e., temporal) flexibility during the design of mitigation scenarios considerably, BECCS plays a prominent role in many low-stabilization pathways. Potential risks associated with BECCS technologies are related to those associated with the upstream provision of the used biomass as well as those originating from the capture, transport and long-term underground storage of CO2 that would be emitted otherwise. (This was written before CarbFix came on the market.) - Energy Systems, Chapter 7, 7.5.5, p533.

How BECCS works: Climate Changing CO2 is removed from the air by trees. The trees are processed into synthetic natural gas (SNG). Ideally, the SNG would be used to power the new city-sized Allam Cycle electricity generator.
The Allam Cycle engine site adds a chemical called CarbFix to it's liquid CO2 emission that will slowly turn the CO2 into solid limestone, then the CO2 is pumped into a porous underground CO2 disposal vault forever.
If this is done on a big enough scale with many of the world's power plants, all the Climate Changing CO2 in the air will eventually be removed from the air and stored underground forever, ending Climate Change forever.
The world has enough porous underground storage strata to store more than 4 centuries of CarbFix CO2 being produced at today's burn rate.

The sketch below shows the same process being done with less efficient old CO2 technology patented in 1930. This CO2 capture technology is still considered state-of-the-market and can be purchased from multiple vendors today.

Wood Burning, + Carbon-Capturing it's CO2, the U.S. Capitol Building Complex in Washington, D.C., could become the
world's first Capitol to REMOVE CLIMATE-CHANGING CO

Step 2:
Use Carbon Captured Synthetic Natural Gas BioEnergy Fuels to Suck Existing Global Warming CO
2 Out Of The Air

Climate Changing CO2 is removed from the air by trees to make their wood, which is pelletized, then gasified, then methanated to to become Synthetic Natural Gas (SNG).  
The wood's energy heats, cools, and provides electricity to the U.S. Capitol's Buildings.   The fire's CO2 is then extracted from the exhaust, liquefied, and shipped in 92 ton liquefied CO2 railroad tank cars to a remote underground storage strata. 
There, the liquid CO2 is mixed with "CarbFix" to cause the liquid to eventually harden into a solid limestone, then injected several thousand feet down into a vast sponge-like underground strata that will act as a permanent storage vault.

Burning Wood (or other Biomass) can be used to remove Climate Changing CO2 from the air.  Coal, Oil, Gas, Nuclear, Hydro, Wind, Solar, don't capture carbon from the air like plants so they won't work.
   A massive tree-farming region and new tree harvesting technology will have to be established in the U.S. Southeast & Pacific Northwest - both the U.S. and Canada - to both control the coming much larger Climate Change-stoked wildfires and to provide the wood necessary to power the Allam Cycle power plants.  Similar regions will have to be established in Northern Europe and Siberia.

Doing It

An image similar to the above image first appeared on this website over 10 years ago when Nancy Pelosi was on her first Tour Of Duty (2007 to 2011) as speaker of the House.  As head of the House, Nancy Pelosi is involved with physical plant projects like the above diagram. At the time, a couple of gas-fired Combined Heat and Power units were being proposed to replace the coal boilers in the Capital Complex Boiler House and I was suggesting on this website we add a carbon capture unit to make the U.S. Capitol the world's first carbon-capture Capitol.

As it turned out, coal was replaced with much cleaner Combined Heat and Power gas turbines in 2018 but no wood-to-synthetic natural gas and no gas turbine post combustion carbon capture modules were included in the upgrade project.

What is being suggested here and now is a good example of a current state-of-the-art "Post-combustion Carbon Capture" retrofit application that could be a small Dutch allothermal wood pellet synthetic natural gas BECCS powered turbine unit such as they have been developing in Europe.
At 90% carbon capture for 130% capital, fuel and power output loss, that amount of parasitic burden is about as good as can be expected for non-Allam carbon capture technology BUT it can be built using developed technology and installed anywhere and used on existing power plants and hospital heating plant equipment to clean up environmentally dirty sites.

There might be sufficient space for the add-on retrofit carbon capture module along the power plant's southern Virginia Ave., SE. street border (Left).
The existing coal railroad spur and coal pile area on the South side of the freeway (Right) could provide space for the Synthetic Natural Gas Generator facility.
Adding these facilities would make the the U.S. Capitol Complex the world's first national Capitol to REMOVE Climate-changing CO2 FROM the air.

U.S. and Global Deep Underground BECCS Negative CO2 Storage Zones

Locating Clean Power Plants Directly Over Them Speeds Up Decarbonization and Drives Down Cost. 
Electricity Transmission Lines, Not Dangerous, Costly CO2 Pipelines Is The Way To Go.

The United States' Carbon Capture and Storage Situation:
"The United States has the technological potential to offset roughly only a decade’s worth of its current CO2 emissions through biological sequestration (i.e., planting trees, etc.,) but a few hundred years’ worth of emissions through carbon dioxide capture and sequestration." - from Congressional Budget Office "The Potential for Carbon Sequestration in the United States, 2007" - Summary, page 2.

There is about 4 centuries of fossil fuel at the current burn rate on Planet Earth. It is estimated there is underground storage space for several times Planet Earth's carbon dioxide.
Far more than is needed to bury all of Climate Change's CO

See CarbFix: CO2 Locked in the ground forever. Watch:   (Skip the ad someone inserted in front of the video.)
If water is added to the liquid CO2 as it is pumped into the ground, the CO2 will turn into limestone [carbonate] after a few years. This locks the CO2 underground forever.

See:  "Geospatial analysis of near-term potential for carbon-negative bioenergy in the United States" by Ejeong Baik, et al.  (pdf)
Locations without carbon disposal will have to rely on renewables - wind, solar - for their electricity.

Bottom Line: BECCS Power Plants for rolling back Climate Change can be located over CO2 storage zones almost anywhere and connected to the electrical grid.


The Race to suck Climate Change out of the air has begun!

Check out: 
(Below is this website's offering.)

Toshiba is working on a city-powering 300 megawatt Allam power plant for 2022
(The 300 megaWatt Toshiba power plant is 37 times larger than the 8 megaWatt Capitol Building Complex Power Plant and the world has 76,000 city-powering power plants.)
How a Full-Sized, Wood-Burning, Climate Change Removing, Power Plant Might look
Once every industrial country has Deep Decarbonized and built their Allam power plants, the current dangerous CO2 level in the air of 413 ppm (Nov, 2020) can be economically reduced to a much safer level of 350 ppm in about 14 years.


This is how the newly developed 'Allam' technology - which was recently patented - could be implemented in a potentially far more efficient and cleaner BECCS facility.
Perhaps as efficient as today's standard non-emission-controlled 60% efficient 'CO2 Dirty' combined cycle natural gas plant.


BACK TO 350 ppm? Since the beginning, the concentration of global warming CO2 gas in the air has been 280 parts per million (ppm).  Burning coal, oil, and gas caused CO2 in the air to rise to 413 ppm.  Experts agree that 350 ppm is the highest CO2 should ever be.
By ending all CO2 emissions (i.e., going to net-zero) immediately, plus removing
548 billion tons of old, existing CO2 from the air long-term, we can reduce the air's CO2 level from about 413 ppm to 350 ppm
1. (Most climate scientists agree.)
The world generates 23 teraWatt-hours (12 zeros, folks) of electricity every year. It would take 76,666 wood-burning 300 megaWatt Toshiba Allam Cycle power plants at 330 days/yr to make that much power
(~ same number of power plants as now)
3One of the above wood-burning Toshiba plants could remove 772,2002 tons of CO2 from the air per year. So: 76,666 plants x 772,200 tons CO2 per plant per year ~ 59 billion tons per year.  548 billion tons / 59 billion tons per year = 9.2 years!
Guesstimate: About half the weight of wood is recoverable CO2 using an allothermal
gasifier and a methanator.  An average tree might weigh 4 tons.  NASA has estimated the world has about 3 trillion trees.  A trillion is a thousand billion.

1 "Almost all scientists, climate experts, and governments agree that 350 ppm is the “safe” maximum level of carbon dioxide."  Why 350? – MN350

By removing air's CO2 using BECCS and other technologies, we can re-set the world's thermostat to wherever we like. . . . . .
The CO2 in the air acts like a blanket - the more CO2, the thicker the blanket. Taking CO2 out of the air is like taking a blanket off your bed - you feel the change quickly.


There Is A Proposal Becoming Popular For Cutting Climate Change CO2 Levels In Half From 420 ppm to 350 ppm

The proposal to suck the CO2 level back from today's 420 ppm to about 1980's 350 ppm:  Why 350? – MN350
On paper, using the new Allam Cycle technology plus burning wood for its CO2 and a very large amount of money, it may be possible to achieve the proposed 420 ppm to 350 ppm CO2 reduction task in a surprisingly short time3.

"As of 2018, CO2 constitutes about 0.041% by volume of the atmosphere, (equal to 410 ppm) which corresponds to approximately 3210 gigatonnes of CO2, containing approximately 875 gigatonnes of carbon."

So, - - - 3210 gigatonnes CO2/410 ppm = 7.83 gigatonnes CO2 per ppm - - - (Each part per million (ppm) of CO2 weighs 7.83 gigatons.) Planet Earth has had air with about 280 ppm of CO2 for more than 10,000 years - the end of the last Ice Age. This means 280 * 7.83 gigatons per ppm or 2192 gigatonnes of CO2 is Planet Earth's natural CO2 baseline. Now, we have 410 ppm or 3210 gigatonnes of CO2 and want to reduce the CO2 concentration back down to 350 ppm.
(The 2018 data above is two years old and the current ppm is close to 420.) So, to remove: 420 ppm CO2 - 350 ppm CO2 = 70 ppm of CO2.   70 ppm * 7.83 gigatonnes CO2 per ppm = 548 gigatons of CO2  [this item is only half-finished at this moment]

Keep in mind we are only talking about CO2 in air and ignoring CO2 that has been absorbed by seawater, land, plants, rocks, etc. CO2 in air ends up being only about 44% of the CO2 we initially emit.
