Transportation DeCarbonization: Rail Transport

Posted by Kelly Burke on Apr 3, 2023 10:50:32 AM

 

In recent political cycles, we’ve heard a lot of talk about Rail transport in the United States. Most of that talk has been in the context of the US needing more rail accessibility, so it may surprise some to discover that the United States actually has the largest rail network in the world. The catch is, this network is used primarily for freight, not passenger transport, and generally when we speak about rail (at least in politics and on the news), we mean for passengers. Freight made up 91% of all rail-use energy in 2019, so we almost exclusively use it for freight transport, in fact.

Rail accounts for 28% of freight transport by ton-miles, but only resulted in 2% of total transportation emissions. So, given that rail is astonishingly more efficient than both trucking and single vehicle passenger transport (cars), part of the focus on rail is an effort to expand its accessibility, particularly on the passenger side. This would have a two-fold impact on emissions because we would see both an increase in utilization of a lower emission intensive mode of transport, and a simultaneous impact on decreasing traffic related emissions from more intensive transport methods.

Freight rail transport in the US uses diesel locomotive engines almost exclusively, where passenger rail has a mix of diesel and electric. Most intercity transport is diesel, where some light rail and streetcar transport is electrified (think Commuter Rail versus Green Line MBTA lines). Full electrification looks like a near impossible hurdle for US freight transport, because of both the long distances and low traffic levels on most rail lines. Additionally, the current electrification modes in use like overhead lines, or third rails are obviously not at all conducive to long rail lines – emission reductions in this segment would most likely have to come from renewable fuels, hybridization, or new technologies. However, electrification of commuter lines may offer an avenue for further sector emission reductions.

The goals and steps outlined by the Federal Government in the Transportation Blueprint for rail include:

  • Infrastructure Investment: electric locomotives and electrification corridors investment, as well as investment in facilitating the availability of clean/renewable fuels.
  • Multi-stakeholder Collaboration: enhanced partnerships amongst those in government and industry with a vested interest, in order to accelerate the pace of technology development, adaptation, and accessibility.
  • Research & Innovation: investment in research to determine the best and most viable strategies for decarbonization of the sector, particularly through the use of pilot programs to optimize the gathering of real-world data and allow accurate analysis of all the vehicle and environment factors involved to accelerate development in the best clean technologies.

Again, as with the other segments being discussed, a successful pivot away from primarily diesel based rail transport in the United States would have longer term impacts on the market in terms of supply & delivery demands for diesel fuel and associated lubricants.

Something to keep in mind, and that we will keep an eye on as the process continues.

California Hydrogen Blending Study Shows Potential Obstacles

Posted by Kelly Burke on Jan 9, 2023 10:23:14 AM

Another avenue being looked into for decarbonization in the US is hydrogen blending. Hydrogen blending would use existing natural gas infrastructure for transport, which obviously makes it very appealing from an infrastructure & logistics standpoint as the majority would already be in place.

However, it isn’t clear exactly what impacts hydrogen might have on said infrastructure, and if it would behave similarly to pure natural gas, or we would see issues with pipeline degradation or operational risks like leaks. California is looking into the issue thoroughly.

The “Hydrogen Impacts Study” commissioned by the CPUC (California Public Utilities Commission) published its results on hydrogen blending impacts in July. The study found that:

  • Hydrogen blends of up to 5% in the natural gas stream are generally safe, but higher blends result in a greater chance of pipeline leaks and embrittlement of steel pipes.
  • Blends of above 5% would require modification of existing appliances to avoid malfunctions, and blends of more than 20% would raise the risk of plastic pipe leaks and subsequent ignition of gas outside the pipeline
  • Due to the lower energy content of hydrogen, more hydrogen-blended natural gas would need to be supplied to consumers to deliver the same amount of energy that they currently use with pure natural gas.

The study concluded that real world demonstrations will be necessary to determine safe levels, and ensure that risks like ignition are eliminated. Southern California Gas, San Diego Gas & Electric, and Southwest Gas filed a joint application with CPUC to implement demonstration projects. The projects seek to use a phased up approach to determine safe levels and assess if hydrogen blending is a feasible next step towards decarbonization for California.

I wrote an article for Oil & Energy Magazine last month on Hydrogen Blended Natural Gas and the projects in California.

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.

National Grid to Pivot NY to Renewable Nat Gas, Green Hydrogen Power

Posted by Kelly Burke on Jul 7, 2022 3:30:00 PM

National Grid has announced it plans to transition New York away from natural gas by 2050 via a combination of renewable natural gas and green hydrogen. New York City alone creates 70% of the State’s emissions, and almost half of those are a direct result of heating buildings and heating water with fossil fuels across its 1 million+ buildings.

National Grid’s strategy is that renewable natural gas and green hydrogen will be used in tandem with electrification projects and renewables like solar. The renewable natural gas and green hydrogen are necessary for reliability of the grid, at least with current technology in place.

I wrote an article for Oil & Energy magazine this month on the topic. You can read that in its entirety here: National Grid says it will pivot to renewable gas and green hydrogen.

Additionally, a quick overview on renewable natural gas & green hydrogen is below.

Renewable Natural Gas

Renewable natural gas, or biogas/biomethane is captured when methane is released from landfills, wastewater treatment plants, food waste, and livestock manure. Emissions from these sources are recurring and otherwise contribute to greenhouse gas emissions but with the renewable natural gas process, they are harnessed, purified, and used to provide gas for cooking, heat, etc, through pipelines in the same manner as conventional natural gas.

Renewable natural gas is chemically similar to conventional, and can run through the same pipeline systems which is a huge plus for infrastructure concerns. However, the infrastructure to purify the captured emissions is essentially nonexistent currently.

There is some concern among environmentalists that biomethane pushes could push agricultural operations to scale further in order to be more cost effective. However, it is worth pointing out that the emissions from the agricultural sector are so high currently, that it seems unlikely capturing spilloff would ultimately function as a detrimental factor in terms of the broader emissions picture.

Even with that particular criticism aside, the infrastructure upgrades and purification setups needed and their associated costs make it unlikely that renewable natural gas can serve as a comprehensive replacement on its own.

Green Hydrogen

Green hydrogen is the cleanest of the hydrogen options and produces zero carbon emissions. It’s produced by electrolysis. H20 is split into hydrogen and oxygen, so there is no waste and the environmental impact is zero. If the process is powered by renewable sources like wind or solar, it is considered a green fuel and has no environmental emissions cost.

The issue with green hydrogen is the infrastructure costs that would be associated with required upgrades to pipeline infrastructure. Currently, 26 pilot programs are running in the United States to test use in existing pipelines as well as production and storage methods.

So while green hydrogen may be the most promising of the solutions long term, it definitely is LONG term.

Renewable Advocates Target ISO New England over Natural Gas Preference

Posted by Kelly Burke on May 9, 2022 8:45:00 AM

shutterstock_686860795

In March, RENEW Northeast and the American Clean Power Association (ACPA) filed a complaint with the Federal Energy Regulatory Committee (FERC) asking the agency to find that ISO New England market rules “provide undue preference to natural gas only resources” and to direct the grid operator to fix its ruled to end that preference.

 

The allegation is based on how the reliability is weighted for natural gas versus “intermittent” resources like solar and wind. For example, solar is scored lower for reliability based on winter supply issues, wind turbines are lowered through summer months based on projected output, but natural gas is presumed to have 100% reliability despite growing concerns that capacity problems in the Northeast Region would potentially make gas inaccessible under full winter loads in extreme situations. If you recall, natural gas capacity in the region has been a concern for quite some time. 

We wrote an article for Oil & Energy in April laying out the details and basis of the complaint, as well as how the capacity auction works and served to generate this complaint. You can read that article in its entirety here: Renewable Advocates Target ISO New England

Bitcoin Miners seek 'Greener' Pastures in the US

Posted by Kelly Burke on Aug 18, 2021 12:57:00 PM

Bitcoin CO2We're going to go millennial this month and talk about the ongoing controversy regarding bitcoin  - not the part you're thinking about, (to the moon!) -  but the controversy regarding the Carbon Footprint of digital currency, and what is seen as its "excessive" energy consumption. 

When most people think of digital currency, carbon footprints don't necessarily spring to mind. After all, the entire industry is just computers (and nerds) right? No shipping, no delivery, no need for massive buildings or corporate offices - the beauty of the whole system is hinged on it being completely digital. However, being completely digital means that the industry relies on using massive amounts of electricity for processing power to "mine". (Mining essentially relies on solving complex mathematics which requires insane amounts of processing power and speed). 

According to industry reports, peak consumption was 143 terawatts, recorded in May. However, consumption has dropped some 60% since then, dropping to 62 TwH in July. Why? Because of 1) the Tesla decision to suspend bitcoin payments on May 12th based on environmental concerns, 2) China's decision in May to crack down on crypto mining, which resulted in approximately HALF of all miners being offline essentially overnight. 

In an odd twist, China's decision to boot bitcoin miners in May might end up being a saving grace for the industry longer term on the energy & carbon side, versus being a single impact drop from kicking everyone offline. Miners are increasingly moving to base out of the United States, where an increasing focus on renewable energy driven power and simultaneous development of more and more efficient processing equipment should help continue to drive down the overall impact of the industry. Mining works on thin margins, and electricity is often the most changeable variable overhead number, which also bodes well for enhancing renewable use as countries like the US focus on making renewable energy options more attractive financially than they have been historically. 

As anyone who's tried to read anything about bitcoin/digital currency is aware, its pretty confusing stuff. We wrote an article for Oil & Energy Magazine this month about the ins and outs of digital currency's Carbon issue and how it looks to be moving forward.

Biden's Offshore Wind Plan Bolsters NE Clean Energy Goals

Posted by Kelly Burke on Jul 22, 2021 11:11:53 AM

shutterstock_1454940068

The Biden Administation has the ambitious goal of bringing 30 gigawatts of offshore wind online by 2030, and 1.4 of those gigawatts are slated to come from the New England coast. 

The move toward more offshore wind is part of the goal of reducing US carbon emissions in half by 2030, a goal that dovetails nicely with goals set by the New England region's member states on climate action. ISO New England's 2021 outlook report released in April outlines some of the anticipated advances, including both the 1.4 gigawatts of offshore wind, 3.5 gigawatts of solar power, and 800 transmission project to connect clean energy projects by 2030. 

All of the New England region's states have set specific carbon goals that line up with (or exceed in some cases) the Federal Government's goals.  These include:

  • Connecticut: zero-carbon electricity by 2040
  • Maine: Carbon Neutral by 2045
  • Massachusetts: 80% renewable energy by 2050 (more details on MA here: MA Climate Change & Environmental Justice Bill)
  • New Hampshire: 25% renewable energy by 2025 (no specific zero carbon goal outlined)
  • Vermont: 90% renewable energy by 2050
  • Rhode Island: zero-carbon electricity by 2050 

On the wind front specifically, Rhode Island is the only New England state with a currently operational wind farm, but the Vineyard Wind Project set to bring offshore wind online in Massachusetts received federal approval in March, and is projected, upon completion, bring 800 megawatts of power to businesses and homes throughout the state.

Maine Stalls on Path to First Statewide Consumer Owned Utility

Posted by Kelly Burke on Jul 14, 2021 11:07:00 AM

shutterstock_102519710Maine lawmakers have been pushing for the state to create the first statewide, publicly owned utility in the US. The legislation proposed in June would have created the entity (Pine Tree Power) as a nonprofit utility that would use issued bonds to purchase the asset holdings of the current suppliers (Central Maine Power & Versant). The bill passed the House but stalled in the Senate, ultimately being defeated by one vote on questions raised about how the utility would cover the shortfall in property tax revenue that would arise from the exit of the current utilities. The shortfall was estimated at $90 million dollars, which is normally paid out to cities and towns.

Given the failure in the Senate, as well as the likelihood that Maine governor Janet Mills would veto the project should it pass, supporters are reportedly looking to pursue the project as a ballot initiative. Supporters see the project as a necessary pivot from the privately held utilities because they project that it would be cheaper for ratepayers, and would be a step forward towards Maine's goal of 100% renewable based power generation. 

The story in Maine is multilayered and complicated  - and still ongoing. We wrote an article for Oil & Energy Magazine that runs through a more detailed overview of where the issue stands currently. You can read that article here: Power to the... International Corporate Ownership?

MA Passes Landmark Climate Change & Environmental Justice Bill

Posted by Kelly Burke on Apr 1, 2021 3:07:36 PM

shutterstock_172545956

Friday, March 23rd, Massachusetts Governor Charlie Baker signed into law Senate Bill 9 "An Act Creating a Next Generation Roadmap for Massachusetts Climate Change Policy" that includes provisions described as "some of the most aggressive greenhouse gas emissions reductions targets in the country"

The ultimate goal of the bill is for Massachusetts to achieve net-zero carbon emissions by 2050, and includes 5 year sublimit goals to that end for impacted sectors (transportation, buildings, etc).

The bill also serves to codify Environmental Justice provisions into Massachusetts law, to both define disparately impacted communities, and provide new tools and protections for those communities going forward. As part of the Environmental Justice approach, $12 million in annual funding was established for the Massachusetts Clean Energy Center to create a pathway to clean energy for environmental justice communities, minority and women owned businesses and fossil fuel industry workers. 

The Department of Public Utilities (DPU) is additionally required to balance equity and accessibility as part of their decision making process regarding regulations in addition to safety, system security, and emissions reductions. Lastly, the Massachusetts Environmental Policy Act (MEPA) is expanded to require environmental impact studies for all projects that impact air quality within a mile of Environmental Justice Neighborhoods and evaluate not just the proposed project's impact but the cumulative impact to the area of projects over time. 

Other major takeaways from the bill:

  • Utilities - first-time greenhouse gas emissions standard for municipal lighting plants, requiring 50% non-emitting electricity by 2030, 75 percent by 2040 and net-zero by 2050.
  • Solar - The bill prioritizes equitable solar program access for low-income neighborhoods. It also provides solar incentives for businesses by exempting them from net metering cap so they can set solar up on business properties to offset electric usage (and cost).
  • Wind - utilities will be required to buy an additional 2,400 megawatts of offshore wind 
  • Natural Gas - Enhanced pipeline safety goals that require adopting provisions including increased fines for safety violations, and enhanced training/certification requirements for utility contractors. Also sets targets for leak reduction along pipelines. 
  • Technology & Other Related Items: Senate Bill 9 also sets benchmarks for clean energy technology - electric vehicles, EV charging stations, anaerobic digesters, solar technology, and energy storage technology. Additionally, on the consumer side there are new regulations set for appliance energy efficiency. 

Obviously, the bill is very comprehensive and there are a lot of details and policy changes involved, some of which we won't know the exact implications of until new projects that are under its scope start rolling out. You can read more on the exact provisions at the Mass.gov website if you are interested in digging into the details, starting with the official press release here: Governor Baker Signs Climate Legislation to Reduce Greenhouse Gas Emissions, Protect Environmental Justice Communities

Maine Central Power Clears Regulatory Hurdle, Stalls on Legal Challenge

Posted by Kelly Burke on Feb 26, 2021 11:17:00 AM

hydroelectric stock

Central Maine Power's proposal for a 145 mile electricity transmission line through the Western part of the State has cleared the final regulatory hurdle. Central Maine Power (Avangrid) recieved a Presidential Permit from the US Department of Energy for their $950 million dollar "New England Clean Energy Connect" (NECEC) Project to be able to cross the Canadian Border. (As an aside, if you want to read about the project in detail their website is a great resource: NECEC

When completed, the project will run 1,200 megawatts of hydroelectric energy from Hydro-Quebec to Massachusetts. The project is funded by MA ratepayers but arguably will help the entire New England region's grid. 

The permit was the last major hurdle outstanding for the project, but more obstacles have popped up. As crews prepared to go to work when the DOE permit was granted, a judge granted an injunction to stop work for 30 days as outstanding filings are adjudicated regarding a separate permit from the Army Corps of Engineers. Work is stopped as the court process moves on, but Maine Central Power is confident the project will continue. 

Upon completion, estimates say the project will reduce regional carbon emissions by 3-3.6 million metric tons per year (the equivalent of removing 700,000 cars from the road) Another portion of the project involves $200 million in upgrades to the Maine power grid, and a $250 million high voltage converter station in Lewiston that will direct current into alternating current to feed the regional grid.
