COP28: Takeaways from Dubai

Posted by Kelly Burke on Feb 2, 2024 7:00:00 AM

The UN’s Climate Change Conference, or “COP28” Summit was held from November 30 through December 13th in Dubai, UAE. The Conference consisted of 150 heads of State and Government and 85,000 participants representing countries, organizations, etc. This year’s summit focused on where the world is in relation to the goals initially outlined in the Paris Agreement (forget what that is? Refresher here: LINK). Spoiler alert – the world is nowhere near achieving the goals outlined, and the focus became how the countries involved can speed up their action on climate change mitigation through multiple avenues.

For the first time, notably, this conference dealt with if there would be:

  • An agreement to end fossil fuel use (they ended up with a loophole heavy statement on a goal to “transition away”, more on that below)
  • An inclusion for the first time of agricultural emissions in countries calculations and mitigation plans
  • A focus on funding for smaller and poorer nations to begin their transitions to renewables.
  • An agreement to triple renewables, and double the rate of energy efficiency advancements.

The sections below give a little more context and detail of the major event items, if you are curious:

“Transitioning Away from Fossil Fuels”

Much of the news from the summit centers around the “historic deal” to “transition away” from fossil fuels, after a contentious battle over whether the specific language should remain in the final agreement. This inclusion was hailed by many as a huge victory and step towards serious climate change mitigation. However, the final agreement also includes language on Carbon Capture and Utilization and Storage (CCUS), Transitional Fuels, and Carbon markets, which is seen by some as a glaring loophole that would implicitly allow continued fossil fuel use on the premise that when the technology can scale (it currently cannot) those emissions would then be able to be captured, sold, offset, etc.

As a refresher, CCUS captures carbon emissions from large scale sources like refineries, power plants, etc, compresses them, and injects them into reservoirs underground to mitigate the carbon’s impact on the atmosphere). The IEA projects that even at a best-case scenario level of scale through 2030, CCUS technology will simply not be able to capture more than a third of the emissions it would need to in order to reach net-zero emissions.

Methane Emissions: Agriculture in Focus

Highlighted at the summit was agreement on the need to significantly curb methane emissions, with a goal of reaching net-zero methane emissions by 2050. For the first time officially, the organization took a good hard look at agriculture. Agriculture is responsible for 30% of global emissions.

If you’re a Netflix afficionado, you may remember the charts and footage from “What the Health” or “Cowspiracy” that illustrate just how massive the climate impact is from Industrial Agriculture. Much like the protagonist in those documentaries, many wonder why emissions discussions, particularly regarding methane emissions, don’t often include (or center on) Agriculture. The COP28 summit did in fact involve discussion of its impact and resulted in the “Emirates Declaration on Sustainable Agriculture” which, among other things, commits consenting nations to include emissions from agriculture and farming in their national climate action plans for the first time.

Climate Change Loss & Damage Fund and Green Climate Fund

The last COP summit (COP27) set up (on paper) a loss and damage fund to help mitigate financial impacts to poorer nations from Climate related impacts. During the COP28 summit, a focus was put on filling the established fund. The last summit set the fund up, but without being fully funded it was argued that the fund was essentially a meaningless gesture on the part of wealthier nations. Over the course of the two weeks of talks the fund went up to $790 million – that sounds like a lot of money to us, but the estimates on what is needed runs from $100-400 Billion, so at the end of the day, it’s still at less than 1% of target funding.

During the summit, US Vice President Kamala Harris announced the US would pledge $3 billion to the Green Climate Fund, another established fund to help offset the cost to transition to green energy sources in developing nations. It is the understanding of the organization that poorer countries will need financial input from richer nations to facilitate their transition to green energy sources, and this fund is designed to be a source of funding for that.

Renewable Energy Capacity Tripling

The final deal struck at COP28 seeks for countries to triple their renewable energy capacity by 2030. A point of major contention at the summit (and in general) has been the category of so called “transition fuels” and what counts for them. Natural gas is the main sticking point on this – many member countries say natural gas should not count as a transitionary fuel because of its emissions, it’s a fossil fuel, etc – however, for poorer developing nations it is hard to argue that fuels like natural gas are not a huge step forward from existing systems, and it is also a lot more financially in reach than options like wind and solar, not to mention infinitely more scalable.

So?

Ultimately, the view of the summit’s conclusions among members, climate activist groups, and international groups is that the summit was successful and the language included is a step forward but does not go fast enough or far enough for their liking. As an editorial aside, it is difficult to imagine an agreement that did go far or fast enough for some of the groups, so given the disparate goals of all the member nations, coming away with any remotely firm statement on transition should be seen as a positive by most of the involved participants.

Transportation DeCarbonization Blueprint: Pipelines

Posted by Kelly Burke on Dec 1, 2023 7:45:00 AM

As we have been discussing, the US National Blueprint for Transportation Decarbonization breaks the Transportation sector into seven categories, each of which has its own targets for emission reduction/elimination, and strategies for how those declines in emissions will be achieved. The next category addressed in the Blueprint is pipelines.

We don’t generally think of pipelines as “freight” (versus items carried by truck, etc.) but actually, pipelines were responsible for 18% of all freight by tonnage in the US in 2015. In the US, pipelines for petroleum and natural gas span over 3 million miles across the country, and the fuels they carry cover close to 70% of energy use in the country currently. Although pipelines transport fossil fuels, the pipelines themselves are remarkably efficient. The major focus of the blueprint when it comes to pipelines is developing enhanced safety controls to avoid unintentional releases that can cause extreme environmental damage, and development of enhanced leak detection and repair. When pipelines have leaks, the main concern is the released methane, which as we know, has an even greater impact environmentally than carbon itself (more on that here: 2021: Methane Regulations on the Agenda)

Outside of those two major points, there are emissions gains to be realized by moving to more efficient systems for pumps, compressor systems, and other ancillary equipment used to keep fuels moving through the pipelines.

Keep in mind, the steps outlined for pipelines are in theory transitional, as the ultimate goal would be pipeline systems designed to transport sustainable/alternative fuels and carbon, versus fossil fuels. As it stands currently, there are substantial challenges and safety questions regarding pipeline transport of current alternative fuels based on variances in their chemical makeup like solvent properties, flammability, pressure issues, etc.

The steps outlined are:

  • Policy & Regulation: The Safety Act of 2020 has a substantial focus on minimizing methane emissions. This is done under the DOT’s PHSMA (Pipeline and Hazardous Materials Safety Administration). PHSMA has issued multiple regulations on pipeline safety & leak regulation – these regulations target the main two issues around pipeline transport: accidental releases, and methane leaks. (The regulations are included under the US Methane Emissions Reduction Action Plan, if you would like more detail on their specifics)
  • Infrastructure Planning & Investment: Part of the Infrastructure Bill passed in 2021 provides for funding to upgrade the pipeline infrastructure via the “Natural Gas Distribution Infrastructure Safety & Modernization” grant program. This grant exists to fund repairs/replacement of portions of pipelines or their operating systems that are outdated, faulty, or prone to failure. The repairs done through this grant will automatically have a positive impact on reducing methane leaks in the existing system, which, as mentioned, is a major goal of this segment’s planning.
  • Research & Innovation: continuous development of monitoring and reporting technology for methane is the major focus of technological advancements & research for this segment. Enhanced leak detection, and enhanced fire prevention at risky sites (like LNG terminals) are the main focus for existing infrastructure, while research into the risks and requirements for safe pipeline transport of alternative fuels is the focus for the new infrastructure we would need to see in order to transition the system to non-fossil fuels, ultimately/

The main takeaway for this segment's goals is methane leak detection and prevention is of paramount importance. We don't necessarily think of small inadvertent leaks being controlled as being a major "thing" in the way we would think about switching to an EV vehicle, or a similar "large" move. However, the EPA estimates that methane leaks in 2019 were an estimated 57 MMT of CO2 equivalent emissions - more than that generated by the more visible parts of pipeline transport like compressor stations.  Natural Gas & Methane leaks have an enormous environmental impact, and an enormous financial one as well (for a quick refresher, take a look at this throwback article from 2015: Harvard Finds Boston is Leaking $90 Million of Natural Gas Annually )  Stopping leaks and spills as an interim step to control pipeline segment emissions is critically important to the overall plan for carbon emission reduction in the United States.

Boston Based "Farm to Grid" Renewable Energy Pioneer Acquired

Posted by Kelly Burke on Jul 21, 2022 8:45:00 AM

Boston based Vanguard Renewables, a pioneer in the food & dairy industry waste-to-energy space has been acquired by BlackRock for $700 million dollars, with a plan to invest up to an additional billion dollars in the company’s expansion, according to the Wall Street Journal this morning. The expansion plan reportedly focuses on commissioning up to 100 anaerobic digesters for renewable natural gas production across the United States by 2026.

We’ve written about Vanguard’s projects in MA before, so this expansion is particularly exciting, and obviously timely with the push toward renewable natural gas we are seeing in the marketplace.

As a refresher, agricultural and food waste has been a continual issue in terms of both disposal, generated methane emissions, and waste forever. As part of the effort to address that, in 2014 Massachusetts  banned disposal of commercial organic waste by businesses that produce more than a ton of organic waste per week. Organic waste was the second largest contribution to landfills in the State before 2014 and the ban served to divert that waste. But the problem became, well, divert it to where?

The solution that arose in the form of anerobic digesters is genius and has the potential to have a transformative effect on both natural gas production and the impact of the agricultural sector on climate. As a sector of the economy, agriculture contributes 11% of total carbon emissions, not including land use and other factors, according to the EPA. 

carbon emissions EPA

Anaerobic digesters take the methane and other emissions from organic waste (chiefly cow manure, but also food waste) and transform it into renewable energy. The process as a whole serves to divert food and animal waste, reduce odor, capture methane emissions, and produces organic fertilizer which lowers chemical usage. Additionally, the energy farmers produce can be sold back to the grid. It’s a pretty perfect sytem. Extrapolated outward across multiple states, its pretty clear implementing this process would have relatively immediate and tangible impacts.

Everything Old is New Again - Methane Regulations on the Agenda

Posted by Kelly Burke on Nov 4, 2021 12:21:54 PM

Methanemolecule

The Biden Administration has announced new methane regulations from the COP26 Climate Summit in Glasgow, Scotland this week. Estimates are that the new regulations will affect  up to 75% of the methane emissions in the United States. Regulations will apply largely to the Oil & Gas industry, specifically addressing “flaring” (purposeful venting) during production and leaks across the system infrastructure.

Methane is responsible for up to 30% of global warming, according to the UN Environment Program, and is estimated to be 25 times more potent than Carbon Dioxide. In recent years this had led to more focus on methane (versus Carbon) emissions, as because of the potency, decreases in methane are much more likely to have a faster and more meaningful impact on slowing Climate Change.

If this sounds familiar, it’s likely because in 2014 the Obama Administration announced similar Methane regulation controls (you can get a refresher here: Methane & Consumers Giving Nat Gas Headaches ) Those rules were enacted in 2016 and subsequently relaxed by the Trump Admin, before being reinstated by the Biden Admin. Hard to keep track of.

The oil & gas industry is responsible for an estimated 30% of methane emissions domestically, and the new rules are expected to reduce emissions from equipment, production sites, and covered areas by up to 75%. In tandem with the expanded EPA regulations, the DOT’s Pipeline & Hazmat Safety Administration is implementing the PIPES act which upgrades and expands existing pipeline setups to cut methane leakage. Other targets of emission reduction are landfills, and enhancing the abandoned mine & well closure program – orphaned mines have been an oft ignored thorn in the side of the federal government & EPA for decades, abandoned mines often leak methane and other gasses, or pollute their areas (For a refresher on that, check this article out: Accidents Happen: EPA Spill Highlights Difficulty of Mine Decontamination)

In an odd continuation of an ongoing trend, the new methane regulations will be “voluntary, incentive-based” changes in the Agricultural sector. This would seem to clash with the global concern over agriculture produced emissions, particularly those from concentrated feed lot (CAFO) based livestock production. The agricultural sector produces emissions comparable with the entire transportation sector (including airplanes) globally (14-18% for both), and agricultural emissions have increased approximately 12% since 1990, which is in contrast to the focus on emission reduction we have seen implemented (in a mandatory fashion) in other sectors. In terms of emissions, the US Agricultural sector produced approximately 698 million metric tons of CO2 equivalent in 2018, a staggering 36.2% of which was in the form of methane.

One of the items regarding agricultural emission control in the White House Proposal is investment in methane reducing practices like “alternative manure management systems”. Presumably (hopefully) this would be an investment in technology like the anaerobic digester technology we have seen make an appearance in MA, where dairy farmers have been diverting manure & food waste to be upcycled into energy. (More on that here: Mass Dairy Farmers Use Food Waste & Manure to Generate Renewable Energy)

So while we will have to wait to see how the new proposals take shape in actual regulation and enforcement, it’s worth noting that according to reports, the American Petroleum Institute (API) appears to support the proposal, with a response indicating they were “committed” to “continued progress” on methane emission reduction. 2020 methane emissions by oil & gas were down 10 percent versus 2019, but that was as a result of a collapse in production, not because of corrective action. The IEA estimates that 10% of methane could be reduced “at no perceptible cost” and where the US (along with Russia) is one of the world’s largest emitters, the new Biden regulations are an attempt to remedy that and push forward progress on a broader Climate agenda.

Stay Tuned!

Mass Dairy Farmers Use Foodwaste & Manure to Generate Renewable Energy

Posted by Ed Burke on Apr 17, 2020 4:01:00 PM

shutterstock_128724608

Local farms in Massachusetts are producing their own renewable energy, and they're doing it while diverting food waste and dropping their carbon footprint at the same time. How? By utliizing anaerobic digesters, produced by Vanguard Renewables.

The simplified version is that the process takes the potential energy in both food waste and organic waste (like cow manure) and converts it into biogas that is used to reduce energy costs, reduce methane emissions,eliminate food waste, generate heat, and offset carbon emissions. 

Massachusetts implemented a ban in 2014 on disposal of commercial organic wastes by businesses that dispose of more than a ton of organic waste per week. Prior to the ban, this type of waste was the second highest contributor to landfills, so the State mandated that instead of being disposed of, they had to be recycled.

The solution that arose in the form of waste to power anaerobic digesters is pretty ideal - it allows not just farms to upcycle their waste, but also helps food processors, supermarkets, and even fast food restaurants by opening up an avenue for food related industries to dispose of waste economically and in a way that is hugely beneficial from an environmental standpoint. 

I wrote an article for Oil & Energy online that goes more in depth into how the process works and the benefits - you can read that article in its entirety here: Farm to Grid

Harvard finds Boston is Leaking $90 Million of Natural Gas Annually

Posted by Ed Burke on Jan 29, 2015 12:44:52 PM

Yellow caution tape reading, caution gas line buried below

A Harvard University study has concluded that 15 billion cubic feet of natural gas escapes the aging pipelines in Boston - an amount that means we're losing $90 MILLION dollars worth of natural gas through leakage annually. 

The problem with leakage, outside of the obvious environmental and health concerns, as well as the fact that consumers bear the cost of the leakage, is that this leakage is responsible for almost all of the methane emissions given off by the city. As we've discussed previously, methane has a 25 times larger impact on the environment than carbon, and for that reason it's been the focus of new proposed regulations from the Administration and the EPA.

The suggested regulations however, are aimed at fracking companies, which over the past year have shown large declines in the amount of methane leaks, and leaks in general in four out of six of the major shale plays. The reason for that is at the production site, leakage costs the producer money in lost product.

The second sector that the regulations aim at (although they are "voluntary" in this case) is agriculture, which is responsible for the bulk of methane emissions. 

When you break down the numbers however, most emissions come from so called "super users", namely power plants etc., versus fracking sites or even intense agricultural production sites. And as studies like this point out, there is a lot of environmental impact happening passively through leaking in outdated pipeline systems, like those in Boston.

What this study points out on leakage, is that there may be a more efficient way to curb urban emissions of gas, and therefore methane, than imposing sweeping regulations on fracking sites, who already are self-motivated by profit to control product loss. That motivation is less present in urban areas, because the cost of pipe replacement and remediation is high, and the work is complicated to perform without disruptions in densely populated areas. Additionally, remediation of leaks in urban pipelines is a direct cost to the utility as well as the consumer, versus the cost-savings measure it is for upstream producers.

To their credit, both Massachusetts and National Grid have already been working on an accelerated pipeline replacement project. This program categorizes how risky leaks are and addresses them in an urgent to non-urgent priority order. This allows them to address the most critical leaks first, and move forward on remediation without undue and immediate cost burdens on the utility or the consumer.

 Essentially, studies like this point out there are emission control options downstream in addition to the ones happening upstream that can complete the picture and move the entire process forward in a more timely and efficient manner.

Methane & Consumers Giving Nat Gas Headaches

Posted by Ed Burke on May 20, 2014 12:32:56 PM

methane scientific element

 We talked before about the White House's proposed new regulations on Methane emissions, which came on the heels of the Administration supporting increased natural gas exports in response to the Russia/Ukraine debacle. Well the EPA whitepapers have come out now outlining proposed changes on each of the industries involved - you can check those out here: EPA Methane Whitepapers 

The Admin proposed changes cite the Agricultural sector as the largest methane producer, followed by Nat Gas. The difference however, is changes proposed for Agriculture are "voluntary" versus regulatory changes for the Nat Gas sector. As usual, environmental groups cheered and said too little too late, while the industry said given it's in their financial best interest to control leakage (their main source of environmental methane), new regulations are an uneccessary burden. 

As we said before, it's hard not to infer from the timing that increasing regulations on methane is at least in part due to environmental and consumer backlash on exports over environmental and supply/pricing concerns. However, given that exporting should increase revenue greatly for the industry it's a pretty savvy time to introduce regulations that may be costly. 

On the consumer side, news has been breaking recently on the number of gas leaks in communities. In the wake of several explosions,  there has been some digging into just how big a problem neighborhood leaks may be, and the news is not good. Some estimates (including a Boston University Study) peg the number of neighborhood leaks in the City of Boston alone at over 3400, and over 20,000 statewide. (You can read the Boston Globe article on the BU Study here: "Boston Riddled with Mostly Small Natural Gas Leaks" )

The issue with these leaks goes beyond the obvious safety and environmental concerns as well. Gas that escapes en route to the consumer is paid for by the consumer. Its estimated that Massachusetts ratepayers are paying an average of $39 million dollars a year for leaked gas ($640 million-1.5 Billion from 2000-2011 according to a study by Senator Ed Markey's Office)

I wrote a piece on methane regulations and the prevalence of natural gas leaks, and what is being (or should be) done about them for the May issue of Oil & Energy Magazine. You can read the full piece here: Natural Gas Needs to Clean Up Its Act

How is Switching to Nat Gas Hurting the Environment? - It's NOT What You Think

Posted by Ed Burke on Apr 17, 2014 9:30:00 AM

Oil drill in a field

A study published by researchers and scientists with MIT, Stanford, and the National Renewable Energy Library was recently published that is essentially the first in depth look at US Methane emissions. 

Why methane? The environmental issues with Natural Gas mainly come from the presence of methane - which is another green house gas, but 30 times more potent than the carbon dioxide we usually hear about. Approximately 1.5% of natural gas leaks during extraction, processing, transport, etc on its way to the consumer, so methane levels give us a bigger picture of the environmental impact of Nat Gas beyond carbon emissions. 

Surprisingly- Hydraulic Fracturing or "Fracking" is not the problem. You read that correctly - the often hotly debated "fracking" process is not what's causing methane emissions to rise. So what is?

The study found that so called "super users" were responsible for the vast majority of the leaks (some processing plants, factories, etc). The good news is that in theory these repairs arent cost prohibitive, and are generally profitable for the site - at least in the long term -  as they stand to lose less product in transmission. 

The question then becomes - is this an issue that should be legislated on or not? Industry folks say they are already voluntarily correcting issues, and since they have a financial incentive in at least certain cases to do so, they don't need regulatory pressure to move the process forward.  Environmental groups predictably say given the level of leaks still existant, volunteerism is not keeping pace with the level of repairs and upgrades required to address emission levels. 

I wrote an article for Oil & Energy magazine's April issue on this topic, and the related discussion of whether its environmentally "friendly" to switch your fleet to Nat Gas in the long term. You can read that article here: Oil & Energy Online
