Global Energy Monitor: Coal-fired Electricity Plants

November 28

According to The Economist there are more than 6500 coal-fired electricity plants worldwide. Data from Global Energy Monitor shows that China and India in particular are still adding more coal-fired plants to the grid. Even though coal plants are also being retired there is still a net addition every year.

The Economist points out that as solar and wind is becoming cheaper and as grids are becoming better at handling intermittent sources due to advances in storage technologies, phasing out coal has other challenges.

IEA: EU electricity consumers are expected to save an estimated EUR 100 billion during 2021-2023 thanks to additional electricity generation from newly installed solar PV and wind capacity

Aug 8, 2023

Data from IEA's Renewable Energy Market Update 2023 show that consumers in EU will save EUR 100 billion during 2021-2023 due to new low-cost deployments of solar and wind farms. This renewable electricity generation has replaced 230 TWh of more expensive fossil fuel electricity generation since Russia's invasion of Ukraine.

Without these new renewable electricity deployments the average wholesale price of electricity in EU would have been 8% higher.

UK North Sea Transition Authority: Domestically produced gas is on average almost four times cleaner than importing gas in LNG form

Aug 1, 2023

The UK's NSTA - North Sea Transition Authority writes: "Domestically produced gas is on average almost four times cleaner than importing gas in LNG form. This is because of both the way the gas is transferred and, in some cases, the methods of extraction."

Further: "Gas extracted from the UK has an average emission intensity of 21 kgCO2e/boe; whereas imported LNG has a significantly higher average intensity of 79 kgCO2e/boe."

Some may find the statement "Domestically produced gas is on average almost four times cleaner than importing gas in LNG form" misleading as it does not take into account the emissions during combustion of the gas. Combustion of 1 boe natural gas will emit about 344 kg CO2.

The NSTA chart compares the CO2 emissions for LNG produced in various countries and shipped to UK and regasified. 1 boe - barrel oil equivalent - equals 125 kg natural gas.

CarbonTracker: Solar and wind energy potential is 100 times as much as global energy demand. Solar panels on 0.3% of global land area is sufficient to power the world

July 31, 2023

The Carbon Tracker report "The Sky's the limit" finds that while global energy demand (2019) was 65 PWh, current solar and wind technology is able to capture 6700 PWh which is more than 100 times global energy demand. 1 PWh equals 1000 TWh.

The report further says "The land required for solar panels alone to provide all global energy is 450,000 km2, 0.3% of the global land area of 149 million km2. That is less than the land required for fossil fuels today, which in the US alone is 126,000 km2, 1.3% of the country."

The chart shows how much of available land would be required for a country or region to power itself using only solar and wind, using currently available technology.

Lazard Levelized Cost of Energy 2023: Solar and Wind least expensive for new builds

July 19, 2023

In April 2023 the financial services company Lazard published the 16th annual analysis of the cost of electricity production.

  • Solar and onshore wind are the least expensive technologies. Utility scale solar costs between $24 and $96 per MWh, and utility scale wind between $24 and $75 per MWh
  • Solar with storage and wind with storage is becoming competitive with gas combined cycle
  • At utility scale, nuclear is the most expensive technology, with a levelized cost between $141 and $221 per MWh
Some important considerations:
  • Nuclear: the figures are based on the Vogtle new build reactors in Georgia, and includes decomissioning costs
  • Gas: fuel costs are assumed to be USD 3.45 per MMBTU
  • Coal: The high end figure includes the cost of 90% carbon capture and sequestration
  • Gas peaking: Peaking power plants are switched on during peak demand and often have lower efficiency than combined cycle gas plants running in baseload mode

IPCC Special Report Carbon Dioxide Capture and Storage: The impact of carbon capture on fossil fuel based electricity generation

February 4, 2023

The IPCC Special Report on Carbon Dioxide Capture and Storage has a good overview of the costs of Carbon Capture and Sequestration, CCS.

The assumption is 90% CO2 capture rate for power plants of 400-800MW in size. The report shows that with carbon capture, a new Natural Gas Combined Cycle plant requires 11-22% more fuel in order to generate the same amount of electricity. This is equivalent to a 10-18% reduction in generating efficency. This is due to the power needed for the carbon capture process.

A new Integrated Gasification Combined Cycle Coal plant will require 14-25% more fuel (equivalent to 12-20% reduction in efficiency), while a new supercritical Pulverized Coal plant will require 24-40% more fuel (19-28% reduction in efficiency).

For coal plants, the additional use of fuel implies an increase in other emissions, such as particles, soot, sulphur, ionizing radiation and more.

Note that the figures include compression of CO2 but not transport or final storage.

UNECE: Lifecycle GHG emissions ranges for electricity generation

February 2, 2023

United Nations Economic Comission for Europe, UNECE, has published a comprehensive Life Cycle Analysis of greenhouse gas emission ranges for various electricity generation technologies. The study includes everything from mining, transport, power plant building, operations and so on. The study also covers toxicity, radiation, land occupation, and water use. Key findings:

  • Coal: IGCC plants in the US show the lowest emissions, 751 gCO2, whereas pulverised coal plants in China are at 1095 gCO2
  • Natural Gas: Combined cycle plants are 403-513 gCO2, with CCS anywhere from 49 to 220 gCO2. For CCS, 90% of CO2 is captured. The LCA includes capture and compression. Methane leakage is accounted for
  • Nuclear Power: the fuel chain (uranium mining, processing etc) represents the largest share of emissions
  • Hydropower: Emissions are very site specific and show high variability
  • Solar and wind: Most of the emissions are embodied in the infrastructure.

Fraunhofer Institute: Hydrogen fuel cells will not play a major role in road transport

December 22, 2022

An analysis by Fraunhofer Institute shows that battery electric drives are superior to hydrogen fuel cells for commercial road transport.

The study shows that battery electric drive is superior in terms of electricity efficiency: 75% of the electrical energy reaches the wheels compared to only 25% in fuel cell vehicles. Electrical loss in electrolysis and in the fuel cell are to blame.

Furthermore, with megawatt charging becoming standardized in 2023, and with EU regulations requiring truck drivers to stop for 45 minutes after 4.5 hours of driving, a range of 450 km would suffice with charging during the 45 minute breaks.

The author of the study also points out that cost of ownership will be higher for fuel cell electric trucks.

Truck manufacturer Scania states that "We see that battery electric solutions are the first zero-tailpipe emission technology to reach market broadly. For the customer, a battery electric vehicle requires less service than a conventional one, meaning higher uptime and improved costs per km or hour of operations"

US Dept of Energy: Maintenance costs for Electric Vehicles far lower than for combustion engine vehicles

December 11, 2022

The US Dept of Energy report from June 14 2021 concludes that scheduled maintenance costs for battery electric vehicles are 6.1 cents/mile, while a conventional internal combustion engine vehicle has costs of 10.1 cents/mile. Fewer moving parts and fewer fluids explain the differences in maintenance costs.

Abbreviations used:

  • ICEV - Internal Combustion Engine Vehicle
  • HEV - Hybrid Electric Vehicle
  • PHEV - Plug-in Hybrid Electric Vehicle
  • BEV - Battery Electric Vehicle
Hybrid and Plug-in Hybrid vehicles have maintenance costs almost as high as battery electric vehicles. This seems reasonable given the added drivetrain complexity.

UCS: There are enough reserves to electrify the global transportation sector using current technology if a high amount of battery recycling occurs.

November 22, 2022

UCS - Union of Concerned Scientists presents research which shows that there are enough reserves of lithium, cobolt and nickel if recycling of EV batteries is scaled up.

Without recycling, demand in 2060 will exceed available cobolt reserves and will require about 90% of lithium reserves. Important: 'Reserves' are resources that are economical to extract. Without recycling, material costs will increase.

Recycling also has environmental benefits: "By using recycled instead of newly mined materials, reduction of climate-changing greenhouse gas emissions is approximately 64%"

The chart shows that almost half of the cobolt and nickel and a quarter of the lithium required in the US in 2050 can be supplied through recycling of used EV batteries.

IEA Global Methane Tracker: Methane is responsible for about 30% of the current rise in global temperature

November 21, 2022

IEA Global Methane Tracker 2022 states that reduction in methane (CH4) emissions are key to limit near-term warming and to improve air quality. Annual global methane emissions are around 580 Mt, of which 40% is from natural sources such as wetlands. The remaining 60% is from human activity.

The global warming impact of methane is 28 times that of CO2 in a 100-year perspective, and 80 times theat of CO2 in a 20-year perspective. In other words, 580 Mt CH4 emissions equals 16.24 Gt CO2 in a 100-year perspective.

Carbon Capture and Storage in 2022: CCS captures about 0.1% of global CO2 emissions. Most of the captured CO2 is used to extract more oil

October 18,2022

According to Global CCS Institute there are 30 large-scale CCS projects in operation at end-of-2021, capturing 42.6 million tons CO2 annually, an increase over 2019 (38 MtCO2). The captured CO2 is about 0.1% of global CO2 emissions.

Most of the captured CO2 is used for EOR - Enhanced Oil Recovery: Injection of CO2 into oil wells in order to extract more oil. IEA estimates that this accounts for an extra 500.000 barrels of oil per day, which equals 78 million tons CO2 emissions per year.

According to Carbon capture and storage at the end of a lost decade in order to meet IEA's sustainable development scenario, 5.6 gigatonnes CO2 per year must be captured and stored by 2050.

Atmospheric CO2 levels are increasing

September 24, 2022

NOAA/ESRL (National Oceanic and Atmospheric Administration/Earth Systems Research Laboratory) operates the Mauna Loa Observatory in Hawaii, and are collects atmospheric data every hour since the 1950s. The data shows how atmospheric CO2 levels are steadily increasing. In pre-industrial times, the CO2 levels varied between 180ppm and 280ppm.

Notice the saw-tooth pattern in the chart: There are more forests in the Northern hemisphere than in the Southern hemisphere. During the northern winter, the forests release CO2 to the atmospere. When spring comes in the north, forests starts consuming CO2 as part of photosynthesis and this reduces the level in the atmosphere.

Greenhouse gas emissions Norway: Emissions in 2021 same as 2020

July 3, 2022

While CO2 emissions have increased from 35 to 41 million tons per year since 1990, emissions of perfluorocarbons (PFC) and sulphur hexafluoride (SF6) from the aluminum and magnesium industries are now close to 0. Emissions of hydrofluorocarbons (HFC) from air-con and cooling systems have increased, but this should be sharply reduced soon as new coolants with lower global warming potential are used. More on this at Ministry of Climate and Environment.

Oil and gas production represents about 27% of total Norwegian emissions. These emissions are expected to be reduced in the future at the cost of higher global emissions, when on-shore hydroelectric power replaces off-shore gas turbines for powering oil and gas extraction. Numbers are in million tons CO2 equivalents.

Norway has committed to reducing emissions in 2030 by 50% compared to 1990.

Global gas production is accelerating

Updated May 15, 2023

According to 2022 data from the US Energy Information Administration EIA, global production of natural gas is accelerating. Other charts on our site confirm this, and show that gas is in fact the main driver of increased CO2 emissions globally, ahead of coal and oil.

The chart shows a significant decline in gas production in 2020 because of the global pandemic. There is also a noticeable dip in 2009 due to the finance crisis which started in 2008.

Production numbers are in BCM - Billion cubic meters

Will the Covid-19 pandemic cause a reduction in atmospheric CO2 levels? No.

October 29, 2021

With reduced travel and reduced economic activity, global CO2 emissions might be lower than previous years. However, even slightly reduced CO2 emissions add to the overall CO2 levels in the atmosphere.

The chart uses data from NOAA ESRL Global Monitoring Division, Boulder, Colorado, USA and shows the atmospheric CO2 levels for each of the last 10 years. Ever since measurements started there has been a consistent increase in atmospheric CO2 of about 0.5 - 0.6% per year.

The atmospheric CO2 levels continues increasing year over year, as indicated by the upper line in the chart. This chart is updated daily based on measurements from the Mauna Loa Observatory.

Electricity generation: Natural gas is 100 times more deadly than renewables. Coal is 1000 times more deadly than renewables

October 7, 2021

University of Oxford's Our World in Data has looked at the number of deaths per TWh (terawatt-hour) of electricity generated from different sources. Data includes accidents and longer term effects due to pollution and radiation, but does not include effects of CO2 emissions and global warming. Brown coal is the deadliest power-generator with more than 32 deaths per TWh, mainly due to air pollution. This is 1000 times as many deaths as wind, hydro and solar. For the same amount of energy generated, even natural gas causes about 100 times as many deaths as renewable sources.

Nuclear power has a relatively low mortality rate, even when the Chernobyl and Fukushima accidents are included. Our World in Data uses the IAEA/WHO estimate for Chernobyl-related deaths, 4000. This chart uses a higher estimate, 45.000, based on the TORCH report

And now some good news: The ozone hole is (slowly) shrinking

February 23, 2021

Ozone is a colorless gas present in the upper atmosphere which absorbs UV radiation from the sun. Reduced atmospheric ozone leads to sunburn, eye damage and skin cancer. Without any ozone at all there would be no life on earth. CFC (chlorofluorocarbon) gases typically used in refrigerators destroy ozone molecules. In 1989, all UN members ratified the Montreal Protocol , agreeing to phase out the production of ozone depleting gases.

NASA Ozone Watch tracks the size of the ozone hole over the Antarctic and the Arctic. The Antarctic ozone hole reaches its peak size in September/October. The chart shows the mean size of the hole during this period, in millions of square km.

Arctic temperatures are increasing faster than the global average: +5° since 1900

April 30, 2021

Data from The Norwegian Meteorological Institute and The Norwegian Centre for Climate Services indicate that temperatures in the Arctic, as measured at Svalbard Airport (78.24 degrees North), are now at least 5°C higher than 50-100 years ago. The increased temperature in the Arctic leads to thawing of the permafrost, which in turn releases CO2 and methane currently trapped in the permafrost.

Annual mean temperature for 1961-1990 was -6.7°C according to yr.no

The report Climate in Svalbard 2100 by NCCS is an excellent overview of future climate impact in the Arctic.

Food production and greenhouse gas emissions: Data from 119 countries and 38000 farms

April 30, 2021

Ourworldindata has an excellent article based on Poore and Nemecek 2018, based on data from 38000 farms in 119 countries. This is the most thorough analysis of farming and green house gas emissions to date.

The data represents global averages, hence there may be significant local differences. Interestingly, at a global level transport represents a small amount of the GHG emissions.

The data also shows that nuts and a few other foods have a negative land use change figure, as carbon is stored in the trees. Most other food sources require deforestation.

Data is reported as greenhouse gas emissions in kilograms of CO2-equivalents per 1 kilogram of food product.

Carbon Capture and Storage in 2020: CCS captures about 0.1% of global CO2 emissions. Most of the captured CO2 is used to extract more oil

April 19, 2021

According to Global CCS Institute there are 26 large-scale CCS projects in operation at end-of-2020, capturing 38 million tons CO2 annually, no increase over 2019. The captured CO2 is less than 0.1% of global CO2 emissions.

Most of the captured CO2 (30 million tons) is used for EOR - Enhanced Oil Recovery: Injection of CO2 into oil wells in order to extract more oil. IEA estimates that this accounts for an extra 500.000 barrels of oil per day, which equals 78 million tons CO2 emissions per year.

According to Carbon capture and storage at the end of a lost decade in order to meet IEA's sustainable development scenario, 5.6 gigatonnes CO2 per year must be captured and stored by 2050.

The chart lists all commercial operational CCS projects as of 2020. Those in red color use captured CO2 for EOR. Those in grey have stopped operations.

Eindhoven University: Battery electric cars have at least 50% lower life-time CO2 emissions on standard EU electricity mix

March 2, 2021

A 2019 report from Eindhoven University 2019 shows that battery electric cars have significantly lower CO2 emissions compared to similar fossil-fueled cars over their lifetime using the EU electricity mix.

Key assumptions: Driving distance 250.000 km. Battery manufacturing: 85 kg CO2 per kWh. Fossil fuel consumption based on spritmonitor.de and US EPA. Well-to-tank emissions add 30% to tailpipe emissions. Emissions per litre: 3310g (diesel), 3140g (gasoline). EU eletricity generation emissions: 250g CO2e/kWh.

The report assumes an EU electricity mix is used, but also that this electricity mix will continue its trend towards lower CO2 emissions. The Polestar report below does not make this assumption, and probably overestimates the emissions of electric cars.

Units on the Y-axis are number of tons CO2 equivalents.

Polestar 2 battery electric vehicle life-cycle analysis: Lower CO2 emissions than a comparable petrol/gasoline powered car

March 1, 2021

In their own 2019 report, Polestar says that the Polestar 2 BEV (battery electric vehicle) has lower CO2 emissions during its lifetime than a Volvo XC40 ICE (internal combustion engine).

Assumptions in the report: Cars are driven 200.000 km in their lifetime. Chinese electricity mix is used for Polestar 2 manufacturing. Polestar 78kWh/350kg battery cells are manufactured in China and Korea. Emissions for the XC40 163 gCO2/km includes 'well-to-tank' related emissions for petrol/gasoline. Electricity use Polestar: 198 Wh/km

The report finds that if the electricity is generated by wind power then the Polestar generates less than half of the CO2 emissions of an XC40 petrol/gasoline powered car. If the electricity is generated using an EU electricity mix then the emissions savings over the lifetime of the car is about 27%.

Units on the Y-axis are number of tons CO2 equivalents.

Cost of electricity generation in the United States in 2025: Solar photovoltaic least expensive technology

September 10, 2020

A report from the US Energy Information Administration has estimated the levelised cost of electricity (LCOE) generation for new plants coming online in the United States in 2025. LCOE includes all aspects of building and running plants such as financial costs, fuel, operations, management and more.

Photovoltaic solar plants will be the least expensive, with roughly the same costs as geothermal, combined cycle natural gas, and onshore wind turbines.

Coal-fired plants will remain an expensive option. As another post on our site shows, offshore wind costs are decreasing rapidly but remain high in the near term.
