A U.S. scientist who has been studying CO2 capture from ambient air for more than two decades has developed an elegant solution that counters two key limitations of other approaches to direct air capture — scalability and energy efficiency.

One of the biggest challenges to capturing CO2 directly from the atmosphere is its dilute concentration — just 0.04 parts per million, compared to 50,000 to 200,000 ppm in typical point source emissions — means capture techniques must contact a lot of ambient air to get much CO2 out of it.

Since the industrial revolution, humans have emitted around 2,400 gigatonnes of CO2, of which more than 1,000 gigatonnes remain as elevated concentrations in the atmosphere.

The investment opportunities outlook for negative emissions technologies from just a few years ago to today could hardly be more different, and yet much more is required.

Even if highly ambitious greenhouse gas emissions reductions goals are achieved, virtually every scenario to keep warming to under 1.5 or even 2 degrees Celsius increase requires gigatonnes-scale negative emissions by 2050, and scaling upward for the rest of the century thereafter.

As the energy transition quickens, global carbon capture, utilization and storage (CCUS) projects are on track to pull more than 550 million tonnes of CO2 out of the atmosphere every year by 2030, representing a more than tenfold increase over today’s 45 million tonnes per annum, Norwegian consultancy Rystad Energy said.

For many organizations in the oil and gas industry, it may be only a matter of time before hackers penetrate their computing systems and their data is held for ransom, according to a cybercrime expert.

As the oil and gas industry struggles to reduce its greenhouse gas emissions and those of its suppliers, Microsoft Corp. offers a glimpse of the progress companies in the tech sector are making on climate.

Given that the construction industry is one of the planet’s biggest carbon emitters, decarbonizing its most used material — concrete — is vital to reaching net zero greenhouse gas emissions.

Most scenarios for reaching the Paris Accord’s climate targets foresee the need for large-scale carbon negative technologies to reverse the overshoot in greenhouse gas emissions accumulated in the atmosphere.

Known as one of the hard-to-decarbonize, or late-to-abate, sectors for its emissions intensive production process, concrete production has made strides in recent years to implement innovative solutions to lessen its climate impact.
April 26, 2022, 12 AM MDT
An often-cited Achilles heel of renewable power production is that its variable nature requires backup energy storage for those periods of time when the sun doesn’t shine and wind doesn’t blow. Battery backup becomes prohibitively expensive for any period of time longer than four to six hours.

In order to meet the climate goals that Canada has set, there is a need “to go faster, further,” said Greg Twinney, General Fusion chief financial officer.

Even as much of the world is clamping down on emissions of the powerful greenhouse gas methane, much remains unknown about its sources.

Low emissions hydrogen production holds the potential to decarbonize difficult-to-abate sectors like steel making and refining, if it can be produced economically and sustainably.

Some $125 trillion in investment is needed to transform the global economy to achieve net zero by 2050 and avoid the worst impacts of climate change, about $32 trillion of which is going to be required to be spent by 2030, according to the ESG Global Advisors CEO.

Canada has an opportunity to go from climate action laggard to leader with its new climate action plan, suggests Natural Resources Minister Jonathan Wilkinson.

Once a carbon capture, utilization and storage (CCUS) leader, Canada is falling behind other jurisdictions like the U.S. in implementation despite having one of the best tools in the toolbox for incentivizing CCUS: a relatively high carbon tax.
April 7, 2022, 8:18 AM MDT
The federal government has staked a large share of its greenhouse gas emissions reductions on a long fought for carbon tax. At the COP26 UN Climate Change Summit, Prime Minister Justin Trudeau also urged world leaders to impose a global price on carbon by 2030.

The green energy transition was not sustainable prior to Russia’s invasion of Ukraine that has roiled global energy markets, and it’s even more untenable with the doubling down on the transition announced by many countries as a solution to the energy crisis, according to a senior fellow at the Manhattan Institute for Policy Research, Inc.

Canada's emissions reduction plan released Tuesday represents the “boldest and most specific step yet” in cutting greenhouse gas emissions from the oil and gas sector of 30 per cent from 2005 levels and 40 per cent relative to current levels, said Prime Minister Justin Trudeau.

If the concrete industry was a country, it would rank third in greenhouse gas emissions. Representing eight per cent of total emissions, it must be solved from a climate perspective for the major economies of the world to reach net zero, as they have pledged to do around midcentury.

Incoming oil and gas sector emissions reduction targets should be coherent with national targets of a 40-45 per cent reduction by 2030 and be made legally binding, the Net-Zero Advisory Body said in a submission to Ottawa on Monday.

Clean hydrogen production and carbon capture, utilization and storage (CCUS) will play important roles in decarbonizing the global economy, but a major shift to renewables is the dominant means by which greenhouse gas emissions will be mostly eliminated by 2050, according to BP plc.

Cheap wind and solar power, eventually backed by energy storage, offers the best route to net zero greenhouse gas emissions, the CEO behind Canada’s largest solar project told a Calgary Chamber of Commerce audience.
