leaves and underbrush still count as biomass made by photosynthesis, so they're still working within the 2% limit.
UK incident sunlight ~ 100 Watts/meter squared. UK area = 243,610 square kilometres of which: * Arable land: 25% * Permanent crops: 0% * Permanent pastures: 46% * Forests and Woodland: 10% * Other: 19%
Let's ignore the other section (mostly mountain), and say we have 81% of the area to use. = 197324.1 square km 100 W/m2 = 876kWh /m2 /yr = 172856 TWh /yr for the entire country.
Assume a good photosynthesis efficiency of 2%, so we have 3457 TWh /yr of energy to play with. We're not eating any of it, we're not feeding any of it to livestock, this is the real upper limit of what the UK can produce. It'd be something like coppiced willow, since plowing the land would release much of the sequestered biochar back into the enviroment.
Modern pyrolysis will typically split the input energy as 35% liquid, 35% gas, 22% char and 8% waste (lost heat and ash). We'll assume we are going to bury all the char as carbon sequestration. We'll also ignore all of the energy used in collecting and transporting the biofuels and char around.
We have 70% on the pyrolysis input energy as gas and oil equivalents = 2420 Twh /yr The DECC model suggests 2010 UK primary energy demand (the stuff that goes into powerplants and cars ect) was 2580 Twh/yr.
Now, we can get that down with efficiency measures and behaviour change. We're also sequestering a lot of biochar, giving us some breathing space if we aim for just carbon neutral instead of carbon negative. BUT it'd be very tight, and we'd have to import all our food, meaning a carbon cost there too. Tropical countries may do better. It's a very interesting angle to explore.
Oh, yes, it's reliable, but even at maximum funding and effort it buys us 1-2 years at most and then it's back to drawing board.madd0ct0r wrote:I don't think biochar has a cat's chance in hell of allowing us to keep the same lifestlye as current. I do think it is the least unrealible of the CCS technologies available
Any form of reusing carbon has the same problem as burying trees - doesn't change the amount of active carbon pool unless we bury the output somewhere somehow. I also posted about biobuthanol producing bacteria - but these, like algae, are just burying the head in sand and pretending minuscule addition of solar power in both makes any noticeable difference while enabling and strengthening fossil fuel burning energy ecosystem. Instead of making sweeping change, like pushing to eliminate combustion engines as much as possible, as we did with say tetraethyllead.(although I do like Simon's algae, I just haven't sat down and run the numbers there yet. Data for oceanic biofuel production was almost non-existent last time I looked).
I don't think either removes any carbon from the pool, just turns some fuel from mined to grown one.madd0ct0r wrote:1) is using the co2 off smokestacks to feed alage ponds which in turn are dried and used as fuel in the power plant

Correct me if I am wrong, but don't algae blooms and their death and subsequent decay deplete water of all free oxygen killing everything breathing? And wouldn't they also sink with not only carbon, but also a lot of essential nutrients making rebound even more difficult?3) is seeding areas of ocean with minuscule parts of iron, prompting algae blooms. These grow, die and sink, carrying the carbon into the deep ocean and out of the active cycle.
Is there anything in the rules that says we can't dump it into the ocean, or into barren terrain like an abandoned quarry and just cover it over? Would that not sequester the carbon?Irbis wrote:Have you ever held a brick of biochar? It's very light. Compared to dense fuels like anthracite and heavy oils it's easily 4 to 10 times the volume. Now, top soil has limited capacity, and unless we want to chop/plough all forests, wetlands, hills, etc natural lands, we're limited to putting it in farmlands.
Somehow, I am kind of sceptical of amount of biochar that can be put into arable land, especially compared to fossil fuel output we have today. Doubly so because like you said production, distribution, and burying all that biochar everywhere will release yet more CO2.
You dump the iron in silica-rich water. The resulting carbon is sequestered in the form of diatoms. The diatoms then sink, and the carbon is pretty effectively buried on the ocean floor.Irbis wrote:Any form of reusing carbon has the same problem as burying trees - doesn't change the amount of active carbon pool unless we bury the output somewhere somehow...(although I do like Simon's algae, I just haven't sat down and run the numbers there yet.

Well, if you don't care about picking solutions people might actually try, you can call for eliminating combustion all you want. As it stands, the immense difficulty of getting people to stop burning coal and gasoline means that realistically, if that's your only strategy for solving the problem, you have no strategy for solving the problem.I also posted about biobuthanol producing bacteria - but these, like algae, are just burying the head in sand and pretending minuscule addition of solar power in both makes any noticeable difference while enabling and strengthening fossil fuel burning energy ecosystem.
Eliminating leaded gasoline is not at all like eliminating combustion engines altogether. TEL was a gasoline additive, that increased fuel efficiency and made an already useful tool more useful. It could be replaced easily and economically with other methods of improving fuel efficiency, by the time anyone was trying to ban it. It was a case of convincing people to substitute apples for oranges after oranges turned out to be dangerous.Instead of making sweeping change, like pushing to eliminate combustion engines as much as possible, as we did with say tetraethyllead.
Which still reduces the rate at which (presently) sequestered carbon is being pushed back into the carbon cycle, reducing the rate of increase of atmospheric carbon dioxide concentration.Irbis wrote:I don't think either removes any carbon from the pool, just turns some fuel from mined to grown one.madd0ct0r wrote:1) is using the co2 off smokestacks to feed alage ponds which in turn are dried and used as fuel in the power plant

Depends on the algae. Some classes of algae are going to poison other sea life. Others aren't.Correct me if I am wrong, but don't algae blooms and their death and subsequent decay deplete water of all free oxygen killing everything breathing?

This has been studied. Some of the carbon is rereleased; other carbon stays down there for many millenia.And that with optimistic assumption deep water organisms that are IIRC reliant on precisely such fall from above for food won't consume them and release CO2 back to the sea.

You takes your choice of who you listens to on this, of course: NASA/NOAA/UKMetO or BEST, warmists or sceptics.
But it might be worth remembering that the former are arguing for massive government and economic action, action which people would not take voluntarily - that is action which will make people poorer, then. In other words the warmists want to take away your money and your standard of living (for your own good, they would say). And standard of living is not just consumer goods, it's health care, it's regular showers and clean clothes, it's space programmes and education for your kids and many many other things that you will have less of in the green future advocated by warmists - it's your whole life.
