Coverage of global warming potential since May 27, 2021.

We need to better understand hydrogen pros and pitfalls

"...“Depending on the use case, it can make the difference between hydrogen being a reasonable partial decarbonization strategy and … actually making things way worse,” Martin told Canada’s National Observer in a phone interview. Environmental Defense Fund’s research examined existing life-cycle studies from a variety of hydrogen systems to see how high or low releases of methane and hydrogen affect the technology’s efficacy at fighting climate change, along with other factors. What people are reading Why Steven Guilbeault’s roadway remarks sparked a car-crazy culture war By Matteo Cimellaro | Analysis | February 20th 2024 Hydrogen is often referred to as green, blue or grey to indicate its impact on climate change..."

FortisBC starts methane capture expansion at landfill

"...Decaying organics in landfills produce methane. If it escapes into the atmosphere, it is magnitudes worse than if it is burned because methane has a significantly higher global warming potential than the CO2 produced when it is burned..."

BNIM brings a brick facade to the Stanley Museum of Art

"...Nearly 15 years after a flood heavily damaged the original Stanley Museum of Art on theUniversity of Iowacampus, a new museum building designed byBNIMopened in January 2022. The Universitys renowned collections of African and 20th-century art have returned to the campus, including Jackson PollacksMuralpainting, which was quickly evacuated during the flood and has spent the last 14 years traveling to art institutions across the world to appear in temporary exhibitions..."

As natural gas use rises in Victoria, the city says it isn't a clean energy source

"...One of the main purposes of this campaign is to inform the public that natural gas is not a clean energy source, despite the “extensive” advertising on the fuel, Derek de Candole, a community energy specialist with the city, told council on Jan. 26..."

New methane binding process could end insanely wasteful burn-offs

"...The global oil industry wastefully burns off about as much natural gas as is used by all of Central and South America but a new methane binding agent offers a potential way for this greenhouse gas to be converted economically into liquid fuels. Methane is a viciously potent greenhouse gas, if a relatively short-lived one. Over a 20-year span, methane emissions are estimated to have a global warming potential 84 to 87 times that of carbon dioxide..."

Hydrogen 11 times worse than CO2 for climate, says new report

"...Hydrogen will be one of humanity's key weapons in the war against carbon dioxide emissions, but it must be treated with care. New reports show how fugitive hydrogen emissions can indirectly produce warming effects 11 times worse than those of CO2. Hydrogen can be used as a clean energy carrier, and running it through a fuel cell to produce electricity produces nothing but water as a by-product..."

Living the 1.5 Degree Lifestyle Corporate Knights

"...Its harder when everyone wants more stuff, and the jobs all depend on us buying it. So, the only strategy anyone can think of is to produce more carbon-efficient stuff, to build electric cars instead of gasoline-powered, to burn natural gas instead of coal, to make more wind turbines and solar panels, and to dream of nuclear reactors, carbon capture and storage, and hydrogen..."

Lessening the cost of strategies to reach the Paris Agreement

"...Five researchers shed new light on a key argument to reduce greenhouse gases (GHG): they provided the first economic analysis of conversion factors of other GHG like methane into their CO2 equivalent in overshoot scenarios. Although the United Nations Framework Convention on Climate Change (UNFCCC) considers settling for one value of reference (known as "Common Metric") to make this conversion among the Paris Agreement, the models presented here show the economic advantage of flexibility between various factors of conversion. "A key notion in the UNFCCC is to reduce GHG emissions in the least costly way so as to ensure global benefits" highlights Katsumasa Tanaka, primary author of the Science Advances study..."
