Current energy
Policy.
Currently, California has ruled
against nuclear power in favor of renewables such as wind and solar, etc. even
though the current energy situation is one where the state must add at least
4,000 MWe of new power capacity by 2008. They intend to
accomplish this by increasing California's renewable energy production to
20% of the states total energy content by the year 2010. This is a doubling of
the current renewable energy contribution. And this is to be accommodated
without regard to the cost of electric energy. The state's three major
utilities are required to increase their renewable energy capacity by 20%. And
also they intend to obviate some of the new capacity additions by enacting
conservation measures.
In 1975 when I came to California
the CEC said that by the year 2000 the State's electric energy supply content
would be accomplished by adding renewable energy systems. They showed
charts where renewables would supply 40% of California's total energy needs by
that time. I said it would be no where that value. Of course it was only
about 10% by the year 2000 and the deregulation fiasco exposed the
shortage.
Here are the
result of a 20 person of experts who performed a study entitled:
A Low Carbon Fuel Standard For
California
Part I Technical Analysis
In summary, a 10 percent Low Carbon
Fuel Standard target seems plausible, though it requires innovation
in fuel and/or vehicle technologies. Because innovation in the transportation
sector is necessary to achieve long-term climate stabilization in any case, the
fact that the LCFS will stimulate innovation in the near term is an advantage,
not a problem. A 15 percent LCFS target may be possible if some of
the low-carbon fuel technologies currently being developed are successful
and the regulations are flexible enough to allow fuel suppliers and
consumers to take advantage of them. Uncertainties exist in the
measurement of the global warming intensity of transportation fuels,
necessitating a careful approach to regulation and a robust research effort.
Other environmental effects and other approaches to reducing global warming are
also important and deserve study. The Air Resources Board should include
the LCFS as an early action measure under AB 32 (Nunez/Pavley), the Global
Warming Solutions Act.
My comments: This
study was intended to validate the possibility of meeting California's
Bill AB 32 which requires that California reduce its green house gas
(GHG) emissions to the year 2000 levels in four years. In 14 years, the
emissions would be brought down to 1990 levels.
I cannot see
where they arrived at any definite conclusions, but had a lot of iffy statements
and others obfuscations that lead to nothing definite
California is toying with the following
requirements. I do not know where it stands today May 25, 2007.
Regulators
move to curb coal plants.
Rules could ban state
utilities from buying their electricity
California
utilities would be prohibited from buying electricity from most coal-burning
power plants in neighboring states under far-reaching regulations proposed by
state energy regulators Wednesday.
Under the rules, the state's investor-owned utilities
would not be allowed to buy power from any source that spews more carbon dioxide
than does a modern natural gas power plant. Specifically, the source could
not emit more than 1,000 pounds of carbon dioxide for every megawatt hour of
electric energy produced. That's enough energy to light 750 homes for one
hour.
"This is really aimed at encouraging new investment,
new generation and new power contracts to be clean," said Julie Fitch, director
of strategic planning for the utilities commission.
My comments: They are thinking about
letting current coal plant contracts stand, but any new contracts would have to
meet the 1,000 pound CO2 emission for one megawatt-hour energy duration.
This means that no new coal plant contracts would be permitted because no coal
plant will ever meet the 1,000 pound CO2 emission rule. Coal plant emissions for
a one megawatt-hour energy duration are about 2,300 pounds of CO2. Coal plant
thermal efficiencies max out at about 38%. A plant of 38% efficiency would
exhaust about 1,500 pounds per hour of CO2 for each energy generation of one
Megawatt- hour.
I doubt that anyone would consider
building a super critical pressure multiple reheat coal fired plant in an
attempt to meet the 1 MWh = 1,000 pound CO2 emission goal. These have been
maintenance nightmares due to the ultra high super critical pressures above
3,300 psig levels.
California's State requirements for
gasoline
All gasoline shall contain biofuels of the following
minimum;
20 volume % by 2010,
40 Volume % by 2020
75 Volume % by 2050.
Biofuels are defined as either ethanol or
biodiesel.
My comment: Isn't this a farce? Do
they think there is enough farm land area in the State of California to grow
enough biofuel plants to supply 75% by volume of all fuels needed by the
vehicle fleet.? And what will biofuels do? They put out as much CO2 as gasoline
and diesel fuels for the heating values they provide.
Two new California senate
bills are proposed to reduce carbon in the fuels used for vehicles. A 10%
reduction In emissions must b accomplished by January 1. 2010.
Bill
494 Under the Alternative Fuels Law, requires the California
Energy Resources Conservation and Development Commission
(CEC), in consultation with certain entities, to develop
and adopt a state plan by June 30, 2007, to increase the
use of alternative transportation fuels and set goals for
2012, 2017, and 2022 to increase alternative fuel use in
the state that meet certain requirements. (Health and
Safety Code 43865).
Bill 210 Requires the ARB to adopt, implement, and enforce a
low-carbon fuel standard by January 1, 2010, that achieves
GHG emissions reductions, and at least a 10% reduction in
GHG emissions in furtherance of the limit established by
the CGWSA.
I Wrote an e mail to Senator Kehoe that
said that reducing the carbon in a fuel will not provide a reduction in the
green house gases because carbon produces the energy and it will just burn more
of the fuel and produce the same amount of green house gases. The Senators reply
was the following which shows she does not understated the principles of
combustion. Also I do not know what clean fuel options are available except
hydrogen which is not available for vehicular fuels certainly not by Jan 1.
2010.
Dear Mr. Lutz:
Thank you for your email regarding your concerns over SB 494. This legislation
would create clean fuels made from renewable resources that on a full-fuel cycle
and energy equivalent basis do not increase greenhouse gas emissions or other
air, water and criteria pollutants. The bill also creates a process for the Air
Resources Board to certify vehicles that can run on clean fuels.
SB 210 includes language to ensure that no environmental or public health
backsliding results from the administrations efforts in finding other fuels or
blends of fuels to reduce carbon.
Both SB 210 and SB 494 will next be discussed in the Assembly. I appreciate
your input as I consider making changes to these bills.
Senator Christine Kehoe
I wonder what clean fuels from
renewables are possible where the reduced carbon emissions are possible? If we
examine the table below, all of the fuel options have CO2 emissions except
hydrogen. What possible fuel could be used to meet the requirement of Low
Carbon Fuel Standard (LCFS) emissions per delivered heat value. Ethanol produces
more CO2 per heat value compared to
gasoline. Also the Bills do not specify exactly what the requirements are for a
clean fuel.
Finally someone came to their senses
and dropped the measures that do not make any sense
California State Senate Democrats and
environmental advocates held a press conference yesterday as a package of bills
to implement AB 32 with specifics to reduce greenhouse gas emissions and improve
state planning for climate change as well as improve air quality, started making
their way through committees in the Assembly. They stressed how important the
legislation is for the state of California to maintain its world-renowned
stewardship of the environment.
However, despite the push for these bills, all of
them labeled as Senate Democratic caucus priority legislation and with the
backing of key environmental advocacy groups including the California Sierra
Club, the American Lung Association, Natural Resources Defense Council,
Environment California, Clean Power California and the California League of
Conservation Voters, there were stinging defeats at the Assembly
Transportation of three of the measures which failed to pass and may be dead for
the year.
My comments: The package
of bills that were to implement AB 32 were too general and not definitive enough
to make any sense. Sometimes in an effort to cover the water front the language
is so vague as to not be definitive or enforceable. These three failed
measures were in that category. It is also clear that bill AB 32 is
not definitive enough to be a legal document in the real world. The problem is
the legislators do not have the technical knowledge to write such bill and do
not seek the advice of those who do. This would be true with such organizations
as the Sierra Club and the California League of Conservation Voters. If a
contract is not definitive and enforceable it is not a legal document.
it also appears that the
Governor is also in this category and thus fires the chairman of the
ARB to compensate. The new ARB chairman will need to be a politician rather than
a technical leader. And it is true since the new ARB chairwoman is a lawyer.
Draft bill imperils states' bid for
emission cuts
The above is the head line in the
Sacramento Bees' news paper.
California has been battling the federal EPA for two
years over a state law that would require automakers to reduce greenhouse gas
emissions, mainly carbon dioxide, by 25 percent from autos and 18 percent from
SUVs by the 2009 model year.
I will only say here that the
Democrats and Republicans are smart enough to not pass a requirement that is
impossible to meet even though California is nutty enough to propose it.
A view point that parallels mine.
"...to
establish a renewable portfolio standard that mandates 25 percent of all
electricity come from clean energy alternatives such as wind and solar by 2025."
One
wonders whether that is 25% of production or 25% of capacity. Since the
availability of wind and solar are both in the 25-35% range, a 25% of production
mandate would require a solar/wind generation capacity equal to approximately
100% of peak demand. The economics of that alternative would truly be "a wonder
to behold". That is the kind of thing that happens when laws are voted on by
people who have no clue about the implications of their votes, such as the great
majority of members of the US Congress.
Maybe
Congress can also mandate a technologically elegant, energy efficient,
economically viable, high capacity, high delivery rate electric storage
technology in conjunction with the solar/wind mandate. After all, nothing is
impossible if someone else has to accomplish it!

The above goes also for California
lawmakers.
Plug in vehicles
are all the rage now, but Toyota has reservations.
Carmakers question PHEVs
Not everyone
is PHEV-crazy. While Toyota is the leader in hybrid technology it remains
cautious about plug-in hybrids. When the plug-in hybrid conversions were first
announced, Toyota opposed altering its vehicles. Later, the car company said it
would study the technology with the possibility of eventually offering it as an
option.
"Toyota
believes that plug-in hybrid vehicles have potential in the mid- to long-term,"
a Toyota spokesman said. "However, currently available battery technology
[nickel metal hydride] is not capable of providing a suitable platform for PHEVs,
because it would take inordinately large, heavy and costly battery packs to
provide meaningful range extension. We believe that it will take some time until
the next-generation technology [most likely lithium-ion] can
perform to the levels that allow us to provide the same level of reliability,
warranty, manufacturing and service cost."
My comment: Metal
hydride batteries cannot be discharges fully because the voltage drops
significantly as discharging takes place. Tom Edison found this out years ago,
California is
moving away from coal, but the rest of the country is moving toward it.
California's global warming efforts are all for naught. We will see if
renewables or coal predominate. What do you all think?
Coal projected to be bigger source of electricity
Jan
7 - McClatchy-Tribune Business News Formerly Knight Ridder/Tribune Business News
- Kathy Still Bristol Herald Courier, Va. The federal Energy Information
Administration's annual energy projection for 2007 and beyond predicts coal will
be used even more to generate electricity.
Coal, natural gas and oil will continue to provide the same level of
energy supply for the United States, even though growth occurs in biofuels and
other renewable energy sources, according to the report.
"EIA's
2007 projection is both welcome and cautionary." Kraig Naasz, president and
chief executive officer of the National Mining Association, said in a news
release.
"The
forecast that coal will increase its share of the U.S. electricity generation
market to 57 percent, and thus increase its share among major fuels, should
be welcome news in a country blessed with the world's largest coal reserves."
The EIA
expects rapid growth in coal use for both electricity generation and for coal
liquefaction, which by 2025 is projected to be the second largest use of coal
production for electric power generation.
My comment: California
intends to again buck the tend and use renewables for future electric energy.
This was tried in the 1975 - 2000 year era and remember what happened? Gov Davis
was disposed and several natural gas fired plants were hurriedly built. What
goes around comes around as the saying goes.
Implementing the Renewables Portfolio Standard Program
Each California electrical company is required
each year to obtain a minimum amount of electricity from renewable energy
resources, eventually reaching procurement equal to 20 percent of total
retail sales. To fulfill this requirement, each company must prepare a plan
for obtaining renewable energy.
My comment: This requirement is
for energy, not power. In other words the utility cannot add 20% power capacity
and meet this requirement. It must ultimately generate 20% of its total; energy
by renewables. For example a wind machine that actually has a capacity factor of
25% must have a power capacity of 4 times that to meet the requirement of energy
production. In my opinion no utility will ever reach 20% energy production.
using renewables
The North American Electric Reliability
Council says that by 2015 the country will need an additional 141,000
megawatts of installed power capacity to accommodate an expected 19 percent
increase in electric energy usage. Only 57,000 megawatts are currently on
the drawing board. Hardly any of these are in California.
I ask you all. Do you really
think that California can meet the additional 19% increase in electric
energy output by shutting down the existing coal plants and adding renewables?
Looks like we will have the year 2,000 energy fiasco all over again and hurry to
install many natural gas fired plants. Remember each 1,000 MWe NG fired
plant exhausts 150,000,000 cubic feet of CO2 per day.
Gov. Arnold Schwarzenegger must decide whether to
approve two bills that environmental advocates say will help the state achieve
the greenhouse gas reduction goals that he supports:
-
AB1012
requires the state Air Resources Board to adopt regulations that will require
half of all new cars and light trucks sold in the state to be powered by
clean-burning fuels.
-
SB1368 would
prohibit utilities in the state from buying electricity from high-polluting
power plants. ( This means coal fired plants from other
states)
My comments:
What clean burning
fuels are available? Hydrogen is but where does it come from? Certainly
not renewables. Ethanol? Not enough corn in the world to supply ethanol.
Replace 20% of
electric energy from coal plants operating in other state? Replace them
with Combined cycle Natural gas plants? Natural gas cannot be the future
fuel for California.
It appears to me
that they are calling the Governor's bluff when he said we will be back to 1990
CO2 levels by 2020.
It does not appear
that the rest of the US is too concerned about global warming. Here is news of
enormous numbers of gas fired plants to be installed. California depends
on natural gas plants and the cost of Natural gas will certainly go up with the
huge new demands.
Mirant Announces Agreement for Sale of Six U.S. Gas
Plants
ATLANTA, Jan 16, 2007 /PRNewswire-FirstCall
Mirant Corporation (NYSE: MIR) announced today
that it has entered into a definitive purchase and sale agreement with LS Power
Equity Partners, a member of the LS Power Group, for the sale of six U.S.
natural gas fired plants for a purchase price of $1.407 billion, which includes
estimated working capital. The net proceeds to Mirant from the sale after
extinguishing $83 million of project-level debt are expected to be $1.324
billion. The company does not expect to recognize any significant tax or book
gain on the transaction. The U.S. plants being sold are the following: Zeeland
(903 MW), West Georgia (613 MW), Shady Hills (469 MW), Sugar Creek (561 MW),
Bosque (546 MW) and Apex (527 MW), constituting a total of 3,619 MW. The
transaction is expected to close by the second quarter of 2007 after the
satisfaction of certain customary conditions to closing.
News from the Governor
In the Governor's speech on taking
on his second term he outline a plan to meet the state's ambitious greenhouse
limits. He mandated a transition to different auto fuels such as ethanol,
natural gas, biodiesel, and electricity. Maybe Cellulose plants such as wood and
leaves will be made into ethanol, but it stretches my imagination that they
could supply very much fuel. This brought some environmentalists out of the
woodwork. They suggested we dedicate 800,000 acres of farm land to sugar cane,
sorghum, or other ethanol based vegetation. However, sugar cane does not grow in
the US because it requires too long a growing season and too much water.
Moreover, we will plug our car
batteries in at night time and drive them on battery energy during the day. He
does not remember that this did not work ten years ago, but now we
will get a super battery some how. And where the fuel comes from to
provide this night time energy was not stated. Probably some power plant
that does not emit CO2.
When this all comes due in 2020 it
will all have been forgotten and a new crew will suggest a program to do away
with these terrible green house gases. In 1975 California was to be 40%
renewables by the year 2,000. No one remember that now as we strain to get 10
percent.
Here is how the state of California
will reduce green house gases. Build a plant that is fueled with natural gas.
What does it do for the green house gases? It exhausts less GHG than a coal
fired plant, but the GHG exhausts are not trivial. This plant of the latest
technology exhausts 80,000,000 million cubic feet of CO2 GHG every
day it operates at full power. And the oversight folks up AB 23 will permit the
plant. And probably many more like it if we are to keep up with the
load growth demand.
At a capacity factor of 90%, this
one plant will produce about 15% more electric energy annually than all of the
wind machines operating to gather in California.
Moreover, remember a nuclear
plant of this capacity would not put any green house gases into the
atmosphere. Does the State really want to get rid of global warming?
PG&E Breaks Ground on Gateway Generating Station in
Antioch
SAN FRANCISCO, Jan 24, 2007
/PRNewswire-FirstCall
Pacific Gas and Electric Company today broke
ground on a new power generating station that will provide PG&E's customers with
530 megawatts of power using the latest fuel-efficient and
environmentally friendly technologies. Named PG&E's Gateway Generating Station,
the new plant represents the "Gateway" to the future of electric power
generation as well as its position near the Delta.
The 530-megawatt, natural gas-fueled Gateway project is the first new
power plant to be constructed by PG&E in nearly 20 years. Among the facility's
environmental advantages, PG&E will employ "dry cooling" technology -- which
uses 97 percent less water and produces 96 percent less discharge than a
conventional water cooling system -- to avoid the use of river water. Also, the
combined cycle technology will decrease fuel use and greenhouse gas emissions,
the primary contributor to climate change. Compared to older plants, the new
plant will yield 35 percent less carbon dioxide for every megawatt hour of power
produced. The new generating station will provide enough electricity for nearly
400,000 northern and central California customers.
The above plant will emit
about 30 Billion cubic feet of CO2 per year.
Because California’s Energy system was over extended during the 2006
year July heat wave, AB 32 comes at bad time.
California's
electricity system recorded 50,270 megawatts during the heat wave. It was
expected that energy demand would peak about 47,000 megawatts. California's
current electric generating capacity is about 45,000 MWe.
California escaped
rolling blackouts during the July heat storm. Imports of nearly 10,000
megawatts, including power from hydroelectric projects in the northwest, kept
the lights on. The next years will be pretty tough years in California due to
shortages of generating capacity. It is not assured that the added generating
can be found every year.
Added energy capacity
will be needed, but none is assured now. The CPUC has directed the utilities to
solicit new capacity. But due to the limitations of GHG imposed by AB 32,
suppliers will be severely limited on what they can offer. Certainly renewables
cannot make up this deficiency of electric energy capacity.
To meet the electric
energy additions extending to the 14 year period to 2020, California would need
approximately 75,000 MWe. And the added amount of about 30,000 MWe is to come
from renewables and conservation? This is pure folly.
The Texas Utilities
Corporation (TXU) does not think that renewables will fill the bill.
TXU Displacing
Older Generation With Advanced Technologies
Faced with
higher fuel costs, over-reliance on natural gas generation, increased demand,
dropping reserve margins and anticipated pressures to regulate carbon emissions,
TXU (Texas Utilities Corp) has made plans for $2 billion of investment in
advanced technologies. TXU outlined its plans recently – and described its
initial investments -- for new advanced power plant technologies in various
markets across the nation at the Edison Electric Institute (EEI) Annual
Financial Conference in Las Vegas.
According to the TXU Corporation, Renewable energy is seen as a
relatively small player in the mix, and the company does not see it becoming a
large part and contributor in this new technology mix. Even if pursued to its
maximum potential, TXU says, it does not have the capacity to meet base load
electric power demand. A new company, TXU Renew, plans to double the TXU
renewable energy portfolio by 2011, bringing the total to approximately 1,400
megawatts.
California talks about renewables to reduce
its dependence on fossil energy, but it does not do it in practice. Here is a
new natural gas fueled plant that will operate full time.
Calpine
Corporation (OTC Pink Sheets: CPNLQ) today announced that its majority-owned
subsidiary Russell City Energy Company, LLC (RCEC) has entered into a ten-year
tolling agreement with Pacific Gas and Electric Company (PG&E) calling for the
delivery of the full output of the 600-megawatt Russell City Energy
Center, a natural gas-fired plant to be built in Hayward, Calif. This
plant will put about 60,000,000 cubic feet of CO2 into the atmosphere every day.
roup called the AMERICAN COUNCIL FOR CAPITAL FORMATION studied
California's plans and Margo Thorning, Ph. D. authored the report which
gave the opinion that California is sacrificing economic well being and job
growth with little or no long-term impact on global GHG emissions.
Some analysts fear that in AB 32, California going it alone is likely to
cause net job loss and leakage of industry to states and countries which do not
have mandatory emission caps-- the so called "leakage issue" - and lead to no
net reduction in GHG.
-
California currently gets 20% of it electrical energy from coal fired plants
located out of state. Under the new law, this practice would no longer be
permitted for future plants. Thus the future power plants would have to come
from natural gas combined cycle plants which will become very expensive due to
the rapidly escalating price of natural gas.
-
Moreover, Combined
cycle plants are fossil fueled plants and their addition would not result in the
reduction of CO2 to meet the goals of Bill 32.
-
Here is a good
one to watch. Under the Law AB 1268 it would not qualify because its
thermal efficiency is only 41% compared to 60% for the latest GE combined cycle
gas fired plant.
Due to the efficiency difference, the Walnut creek plant would
produce 50% more CO2 per day (30,000,000 cubic feet greater CO2) compared to the
GE's latest combined cycle plant. Not a trivial amount is it?
Walnut
Creek Energy Park On November 22, 2005, Walnut Creek Energy,
LLC (WCE), a wholly-owned subsidiary of Edison Mission Energy (EME), submitted
an Application for Certification (AFC) to construct and operate a nominal 500
megawatt (MW) simple-cycle power plant, the Walnut Creek Energy Park (WCEP),
in the City of Industry.
In my opinion
California would not have had green house gas (GHG problems nor electrical
energy shortages and high cost of energy if they had elected to accept nuclear
power plants in the state.
High Mileage vehicles and
Alternative Fuels.
California is going to carry out a program
to develop high mileage vehicles that use clean alternative fuels.
Heading the program is the same organization (
The Air Resources Board) that brought MTBE to California and poisoned the water,
etc for years.
Pursuant to Assembly Bill (AB) 1811, the California Air Resources
Board (ARB) is to develop a joint plan with the California Energy Commission
(CEC) to spend $25 million for the purposes of incentivizing the use and
production of alternative fuels. AB 1811 requires the funds to be encumbered by
June 30, 2007. There are a number of recent state policy directives that call
for substantial expansion of the use and production of alternative fuels made
from biomass and to reduce dependence on petroleum-based fuels. These include
the Climate Action Plan, Executive Order S-06-06, and the
Bioenergy Action Plan for California. To support these policy directives, AB
1811 provided $25 million to incentivize and fund:
Market-based incentives for high
efficiency, high mileage, alternative fuel light, medium, and heavy duty
vehicles, both individual and public fleets, in California.
Production incentives for alternative fuel production in California;
Market-based incentives for the construction of both publicly accessible
alternative fuel retail refueling stations and fleet fueling facilities;
including E-85.
Funding for research, development, and testing of alternative fuels and
vehicle technology.
Incentives to replace the current state vehicle fleet with clean, high mileage
alternative fuel vehicles.
My comments:
It is not clear to me exactly
what they will do here. The fourth bullet seems to be the description where the
funds will be applied to develop and test alternative fuels and alternate
vehicle technology.
The other bullets address
incentives which are obvious to the goals of alternative fuels and vehicles.
In the plans I find they intend
to center on biofuels such as ethanol, biodiesel, and also hydrogen fuels.
For vehicles they center on fuel cell vehicles. In an upcoming meeting they
intend to address the current status of the items including internal combustion
hydrogen fuel vehicles. The latter I consider to be reachable energy. Fuel
cell autos are too expensive and they do not have durability.
I do not think
that biofuels can be provided in quantities that will serve the vehicle market.
As for hydrogen, where does it come from? Since California will not consider
nuclear power, there is no good source for hydrogen. Certainly not renewables. I
believe that hydrogen generated by nuclear power and applied in internal
combustion engines will be the final answer.
In summing up the
totality of all of the above programs, the answer to California's energy problem
is nuclear power. Nothing else will provide an ample economical energy supply
void of green house gases. And the air we breath would be clean.
France has gone nuclear and because of it they have been able to shut down all
of their coal mines. This results in an enormous reduction in green house
gases, and conserves coal reserves for future petrol chemical needs.
