US reducing power sector CO2 emissions while growing economy: study

At-a-Glance:

The US power industry has been making steady progress reducing greenhouse gas emissions, with power sector carbon dioxide emissions decreasing about 10% between 2019 and 2020 because of a mixture of pandemic impacts, energy efficiency and fuel switching away from coal, a July 20 report said. This year’s report, which has been prepared since 1997, highlighted several “dramatic shifts,” as the share of power produced by non-hydro renewables increased 20% from 2019 levels and the share from coal-fired generation decreased by roughly 17%, the statement said. To learn more, read “US reducing power sector CO2 emissions while growing economy: study.”

Key Takeaways:

  • An S&P Global Platts analysis earlier this year showed the US now has at least 20 states, plus the District of Columbia, with aggressive plans in the works for 100% renewable power, carbon-free power or net-zero emissions, roughly double the number from a year ago, while 12 states have not initiated any clean energy plans.
  • The 100 largest power producers in the US own nearly 3,500 power plants and account for more than 80% of the sector’s power generation and reported air emissions, according to the benchmarking report, which relies on data from state agencies, along with the US Environmental Protection Agency and US Energy Information Administration.
  • The top five producers of zero-carbon power in 2019 were Exelon, NextEra Energy, Duke Energy, Tennessee Valley Authority and Entergy.
  • The top five generators with the lowest CO2 emissions rates in 2019 were Exelon, Public Service Enterprise Group, NextEra Energy, Entergy, and Dominion Energy, according to the report.
  • Facilities in Texas produced 483 million MWh compared with just 42 million MWh in Wyoming, but only about 19% of the power produced in Texas comes from coal, compared with 83.9% in Wyoming, he added.

Path to 100% Perspective: 

State, provincial, municipal and in some cases national governments are declaring mandatory targets for 100% clean power. These regulatory targets are often considered renewable mandates as it is commonly understood that wind, solar, hydro and other renewable energy sources are needed to replace fossil-fuel power plants in a zero-carbon emissions future. According to the UCLA Luskin Center For Innovation November 2019 report of the Progress Toward 100% Clean Energy in Cities and States Across the U.S., a growing number of investor owned utilities are making 100% commitments, whether the states they supply energy to mandate the requirement or not. This private-public commitment to decarbonization is continuing to build momentum toward a renewable energy future. 

Airline Industry to Weigh Goal of Net-Zero Emissions by 2050

At-a-Glance:

The airline industry’s global trade group will propose eliminating carbon emissions on a net basis by 2050, as pressure builds to improve the climate goals of a segment that’s come under increasing criticism for its use of fossil fuels. To learn more, read “Airline Industry to Weigh Goal of Net-Zero Emissions by 2050.” Reading this article may require a subscription from the news outlet.

Key Takeaways:

  • The International Air Transportation Association (IATA) will ask carriers to adopt the target at its annual meeting in Boston in October, according to IATA’s director general, Willie Walsh.
  • While airlines including British Airways owner IAG SA, Delta Airlines Inc. and United Airlines Holding Inc. have all made net-zero commitments, IATA hasn’t updated its own goal since 2009. At that time, airlines pledged to cut CO2 output 50% by mid-century, compared with 2005 levels.
  • IATA intends to hold planemaker AirBus SE to a pledge to produce a hydrogen-fueled aircraft by 2035 and said the model needs to have a size comparable to the top-selling A320 narrow body – carrying 150 people – and a range of at least 1,000 kilometers (621 miles).
  • Airlines’ CO2 emissions reached about 915 million metric tons in 2019, according to the Air Transportation Action Group.
  • Based on 2005 levels, IATA’s current target is for carriers to reduce carbon emissions to 325 million metric tons by 2050.

Path to 100% Perspective:

Decarbonizing to meet ambitious renewable energy goals will require new approaches and ways of thinking, especially in aviation. Shifting to hydrogen and carbon neutral fuels is one path the industry can take to reduce carbon emissions. This will require investments in technologies such as power-to-gas and carbon capture to produce renewable fuels at scale for the transportation sector.

The World Is Moving Toward Net Zero Because of a Single Sentence

At-a-Glance:

In 2018, the Intergovernmental Panel on Climate Change’s Global Warming of 1.5°C report stated, to have a shot at achieving the Paris Agreement’s stretch goal of limiting warming to 1.5° Celsius above pre industrial levels, every nation must cut its carbon-dioxide emissions in half by 2030—and neutralize them by 2050. Two years later, eight of the 10 largest economies have pledged to reach net-zero emissions by mid-century. Twenty-nine countries, plus the European Union, have net-zero pledges for either CO₂ or all greenhouse gases, accounting for 14.5 percent of global emissions. About 400 companies, including Microsoft, Unilever, Facebook, Ford, Nestle, Pepsi Co, and Brunswick Group, have signed on with the Business Ambition for 1.5°C pledge, which is built on the IPCC’s analysis. To learn more, read “The World Is Moving Toward Net Zero Because of a Single Sentence.”  Reading this article could require a subscription to the news outlet.

Key Takeaways:

  • Like most statements the IPCC sets down, the most important sentence ever written is just terrible—clunky and jargon-filled. What it says, in English, is this:
    • By 2030 the world needs to cut its carbon-dioxide pollution by 45%, and by midcentury reach “net-zero” emissions, which means any CO₂ still emitted would have to be drawn down in some way.
  • The half-by-2030, all-by-2050 guidance is keyed specifically to emissions of CO2, by far the biggest contributor to warming.
  • According to the World Resource Institute’s Kelly Levin, “Countries with the highest emissions, greatest responsibility, and capability should adopt the most ambitious target time frames.”
  • Since the Clean Energy D.C. Act became law in early 2019, it has been joined by dozens of other national or subnational jurisdictions trying to reach net-zero emissions by 2050.

Path to 100% Perspective:

The IPCC’s statement has proven to be a catalyst that sparked a sense of urgency for government leaders, corporate decision makers and utilities. Renewable energy goals are taking many forms, but they have similar targets and deadlines which can only be achieved through commitment, continued research and collaboration. The renewable energy future has not yet been achieved, but with the growing number of investors, innovators and subject matter experts working towards this goal, the path to decarbonization is coming into focus.

Shell Says Hydrogen Is Heavy Transport’s Future. What Now For Biofuels?

At-a-Glance:

Hydrogen will be the key energy source for global road freight, according to a new report commissioned by European oil major Shell. Electrification is the most economic and environmental solution for smaller delivery vehicles. The study, carried out by global accountancy firm Deloitte on Shell’s behalf, questioned 158 executives in the road freight sector in 22 different countries. To learn more, read “Shell Says Hydrogen Is Heavy Transport’s Future. What Now For Biofuels?”

Key Takeaways:

  • Of those interviewed for the report, 70% ranked decarbonization as a top-three concern for their business and many said they expect hydrogen to be commercially viable in just five to 10 years.
  • Carlos Maurer, EVP of sectors and decarbonization at Shell, stated, “We believe that once produced at scale, hydrogen will likely be the most cost-effective and viable pathway to net-zero emissions for heavy-duty and long-route medium-duty vehicles, and electric mobility will do the same for light-duty and short-route medium-duty vehicles.”
  • Major truck manufacturers in Europe have accelerated the target date for their diesel engine phase-out from 2050 to 2040. Hydrogen and electrification are the low-carbon technology options of choice.
  • Biofuels are more likely to play their largest role in the short term when it comes to the transportation sector; however, there are other transport end markets where biofuels hold a strong advantage.

Path to 100% Perspective:

Decarbonizing the transportation sector will be a key step in realizing a 100% renewable energy future. Investments in hydrogen production, both in policies and infrastructure, will accelerate the timeline for commercial viability.
