GUEST BLOG: GAS INFRASTRUCTURE KEY FOR CLIMATE TECHNOLOGY SOLUTIONS

A report by researchers at Columbia University’s Center on Global Energy Policy presents a well-rounded view on the role that natural gas infrastructure will play in reaching net-zero targets and bridging emerging energy technologies.

Researchers had the Leaders Summit on Climate – during which countries, led by the United States, committed to more ambitious emission reduction targets – as a backdrop for the release of their report. Carbon capture and storage and hydrogen were among the most talked-about climate solutions brought up by world leaders, industry experts, and other key actors during the Summit. The report addresses both technologies while anchoring them to the potential role the U.S. natural gas pipeline system may play.

Natural Gas Is Here For the Long-Haul.

Natural gas dominates the U.S. energy system and is not going anywhere soon. As the researchers explain:

“Studies by energy agencies, universities, and the industry that model future U.S. natural gas consumption consistently show continued use of natural gas for at least the next 30 years, even in scenarios where the country achieves net-zero targets by midcentury. There is no quick replacement for gas in the U.S. energy mix.”

Per the report, some numbers that showcase natural gas’ prominence in the United States include:

  • Natural gas accounts for a third of the country’s electricity generation, a third of industrial energy consumption, and a quarter of residential energy consumption.
  • About 48 percent of U.S. homes (179 million people) currently use natural gas.
  • The three dominant uses for natural gas in the United States are electricity generation, industrial heat, and residential sectors.
  • Total consumption of natural gas has grown by 25 percent in the last decade.

The report adds a new perspective on how to approach both energy and climate solutions by continuing to support natural gas. According to the researchers, there is a need for greater leak detection, repair, and control, as well as retrofitting the existing pipeline network to accommodate fuels like hydrogen, biomass, or even to transport CO2 companies capture:

“Rather, these investments in existing infrastructure can support a pathway toward wider storage and delivery of cleaner and increasingly low-carbon gases while lowering the overall cost of the transition and ensuring reliability across the energy system.”

What does this mean for the U.S. natural gas pipeline system?

Repurposing natural gas infrastructure to transport not only natural gas, but other lower carbon gases, instead of banning, interrupting, or canceling infrastructure projects, will reduce costs and jumpstart low-carbon energy technologies. This is ultimately not a challenge but an opportunity:

“But retrofitting and otherwise improving the existing pipeline system are not a choice between natural gas and electrification or between fossil fuels and zero-carbon fuels… In the same way that the electric grid allows for increasingly low-carbon electrons to be transported, the natural gas grid should be viewed as a way to enable increasingly low-carbon molecules to be transported.”

In the end, the energy transition is about finding smart, technology-driven solutions to address climate concerns. By enhancing an already well-established infrastructure system to transport other gases, the United States will guarantee continued energy access and resilience to all communities in the long term.

Total Electrification — Food for Thought

The old adage, “Never put all your eggs in one basket.” is as true for the energy system as it is for anything else. Diversity of energy sources is essential to ensure we can rely on the energy we need when we need it.

We enjoy a safe, reliable, and affordable energy delivery system here in the Northwest. The interdependence of two amazing but inherently different energy infrastructures makes it so. One system is the machine that instantaneously conveys electricity into our region’s farthest and most remote areas. The other is the natural gas system spanning 128,000 miles (206,000 Km for those of you who prefer the metric system) that delivers warmth and comfort to ten million residents of Idaho, Oregon, Washington, and British Columbia and productive energy to almost 350,000 businesses, institutions, and industries that are the region’s economic engine. The two systems function very differently but are interconnected and operate seamlessly together.

That integrated system is at risk. One of the trendiest and most poorly understood concepts in energy – “electrify everything” – is ascendant. The idea is to eliminate consumer choice in the energy they can use by mandating that everything in our homes, offices, manufacturing facilities, and cars be powered with electricity. Several groups are pushing this idea with a vested interest in its success.

Anybody who experienced the recent Northwest “heat dome” knows first-hand the value of electricity in our daily lives. If you are one of the half-million people who lost power during the February ice storm or one of the hundreds of families who lost homes to the wildfires last summer, you are familiar with its vulnerabilities. You are also likely aware that the natural gas infrastructure continued to operate without interruption during each circumstance, providing hot water, cooking, and some space heat when the electricity was out and fuel for the electricity that cooled homes and businesses when the wind wasn’t blowing and after the sunset.

If our economy – and daily lives – will rely this much on electricity, we need to know the grid isn’t going to break down. Right now, we don’t know that — even just for today’s level of demand. In fact, the chance of a regional power supply disruption will increase to one in four in the next few years, according to the Northwest Power and Conservation Council. Their forecast of significantly increased risk of blackouts and brownouts across the region does not include aggressive policy-driven electrification of buildings and transportation currently being contemplated in some jurisdictions. That’s quite a gamble.

A study from Princeton University finds that electrifying nearly all transport and buildings could contribute to doubling — or more — the amount of electricity required in the U.S. by 2050. For example, over the past decade, the number of U.S. electricity outages has doubled. There is a long list of culprits, including retirements of dispatchable generation like coal and nuclear, high winds toppling tree limbs, wildfires, ice storms, even aggressive squirrels. And because renewable electricity like solar and wind is intermittent, there is increasing pressure on the grid to manage this variability.

The Princeton University study estimates the country will need between double and triple today’s electricity transmission capacity to accommodate the Biden administration’s goal of achieving net-zero greenhouse-gas emissions by 2050. A number of analyses by local utilities demonstrate similar numbers. This objective will be extremely difficult to achieve in large part because no one wants high-voltage wires and substations near their home. Still, there can’t be the electrification of everything without a lot more of those wires and stations.

More interconnections also increase cyber-attack risks by providing more gateways and larger linked attack surfaces for hackers to enter undetected into a vital system to interrupt U.S. economic activity or safety. The more digitized and connected things to a plug, the more activities that have to increase cyber-protection tools and practices.

Not only is it risky to put all eggs in the electrification basket, it’s also unnecessary. The energy delivered by the natural gas system can and will change. Instead of building a whole new energy infrastructure on top of a safe, modern, and highly reliable energy delivery system that currently serves millions of residents and hundreds of thousands of businesses, we can adapt the existing system to more affordably and reliably address our region’s decarbonization goals.

Stay tuned for this series’s next installment when we discuss the promise and benefits of decarbonizing the fuel delivered by the natural gas system in the Pacific Northwest.

On Garbage Man Day, We Celebrate Workers and Our Planet with Advancements in Renewable Gas

Guest Blog: Daniel Gage, President of Natural Gas Vehicles for America

On June 17th, we recognize the hard work of the men and women who collect our garbage and recyclables. They not only keep our communities clean, but with advancements in renewable gas technology, they’re also helping fuel their fleets with clean, renewable natural gas (RNG).

Right here in the Pacific Northwest, landfills are turning trash into renewable natural gas that is then fueling those very trucks sent to collect the waste. It’s full circle.

Renewable natural gas captures organic methane gas from materials like wood, food, trash, and agricultural waste that would otherwise pollute our planet. Instead, that waste is now fueling large truck fleets, decarbonizing parts of our transportation system.

Cleaner air starts with cleaner trucks. It’s not only good for our planet, but natural gas and renewable natural gas vehicles are also more cost-effective at reducing criteria pollutant emissions. When comparing the cost of NOx reduction, natural gas refuse trucks are 86% more cost-effective than diesel and 54% more cost-effective than electric alternatives.

That’s why renewable natural gas use as a transportation fuel has increased 267% during the past five years. In 2020 alone, its use eliminated 3.5 million tons of carbon dioxide equivalents. Now, 53% of all on-road fuel used in natural gas vehicles is renewable natural gas and that number continues to grow with advancements in other renewable gas, such as green hydrogen both of which utilize existing natural gas infrastructure.

In states with clean fuel standard programs, RNG use as a transportation fuel is even greater. Last year in California, 92% of all-natural gas motor fuel was derived from renewable sources. And the California Air Resources Board data confirms that state fleets fueled by this bio-CNG (RNG) achieved a carbon-negative result in 2020, with an annual average carbon intensity of -5.845 gCO2e/MJ. That’s a carbon-negative commercial truck outcome now, not in five or ten years.

Thank you to our refuse industry workers for keeping our communities clean and turning a waste liability into a green energy asset.

Natural Gas Distribution Emissions Continue to Fall

The U.S. Environmental Protection Agency (EPA) recently released its Inventory of U.S. Greenhouse Gas Emissions and Sinks, showing that annual greenhouse gas emissions (GHG) from the natural gas distribution system declined 69 percent from 1990 to 2019. During this same period natural gas utility companies added more than 788,000 miles of pipeline to serve 21 million more customers. Distribution systems owned and operated by local natural gas utilities emit only 0.08 percent of produced natural gas.

The EPA report showing decreasing methane emissions from the natural gas system is more evidence that the industry is pro-actively and aggressively improving their carbon profile.

This continuing downward trend in greenhouse gas emissions from the natural gas delivery system further shows the essential role Northwest gas utilities play in the region’s clean energy future.  The industry has been pro-actively adopting new technologies to reduce the emissions impacts of the gas sector, which compliments the Pacific Northwest’s overall climate policy goals.

Recognizing the imperative of decarbonization, the Pacific Northwest gas utilities and interstate pipeline companies are investing in carbon-free sources of gas such as renewable natural gas and green hydrogen, as well as improving the efficiency of natural gas appliances.

Natural gas, particularly direct-use appliances, are highly efficient and offer lower lifecycle GHG impacts than other products. Natural gas is a reliable and cost-effective fuel that is often the fuel of choice, representing billions of dollars in efficient and well-maintained infrastructure essential to important economic sectors in the Northwest, including food processors, nurseries, the wood products industry and manufacturers.

The EPA has developed and published its Inventory of U.S. Greenhouse Gas Emissions and Sinks for more than two decades. The EPA Inventory represents the most comprehensive assessment of U.S. greenhouse gas emissions available. The Inventory shows a low-methane emissions profile for natural gas distribution systems, shaped by an industry-wide natural gas emissions rate of production that is only 1.0 percent.

GUEST BLOG: Rethinking Natural Gas Bans

By Don C. Brunell

Sometimes being first isn’t good. Such is the case with legislation making Washington the only state to ban natural gas in new homes and commercial buildings.

Thankfully, the legislators ended their session in Olympia and left that bad idea on the table. However, it is destined to come back next year.

The issue is complicated and expensive. Earlier this year, Gov. Jay Inslee (D) unveiled it as part of a package to reduce greenhouse gas emissions. It included a phase-out of natural gas for space and water heating by forbidding the use of fossil fuels for heating and hot water in new buildings by 2030.

The ban trickled down from Seattle. Last month, the city adopted a partial gas ban with an update to its building code that says all new commercial and multifamily buildings four stories or taller must use electricity for heating. Among the questions not answered is new construction in smaller buildings and in houses, although it didn’t restrict the use of gas for cooking.

The natural gas ban was initiated by Berkeley city leaders in 2019. The idea spread to other California cities and more recently to Seattle. But opponents also were at work, and they helped to pass laws in four states — Arizona, Louisiana, Oklahoma and Tennessee — that restrict the ability of cities to ban gas hookups, Dan Gearino, Inside Climate News, reported.

Switching from natural gas to electricity is complicated and will impact everyone. Natural gas dependency is widespread.

With reference to Washington, Rep. Mary Dye (R-Pomroy) told KIRO’s Dori Monson: “It’s a big industry because it provides warmth for about 1.2 million residences, there’s 107,000 commercial buildings and 3,500 industrial buildings that are working under clean, efficient, reliable natural gas. Plus, it fires about 11 percent of our electricity grid. So you’re talking a very large labor force.”

For example, one-third of Clark Public Utilities electricity is generated at the River Road natural gas-fired generating plant. Clark PUD provides power to more than 203,000 customers in Vancouver and throughout Clark County.

Puget Sound Energy is our state’s largest energy utility providing electric power to more than one million customers. PSE also generates one-third of its electricity at nine natural gas-fired power plants.

Nationally, natural gas produced the most electricity in 2020—more than 40 percent. Renewables, including hydro, wind and solar, accounted for 20 percent.

At present, electricity is affordable in Washington but adding new generating capacity is expensive and will drive power rates higher.

In 2019, Washington had the fourth-lowest average electricity retail prices in the nation, while 56 percent of the state’s households used electricity as their primary home heating fuel. Getting to total electricity dependency is difficult especially if the Lower Snake River dams are breached.

While natural gas electrical generation is important, natural gas availability is vital to some smaller communities. For example, the cities of Enumclaw and Ellensburg are the natural gas providers to nearly 9,000 customers.

Renewable natural gas (RNG) from farms, garbage landfills and waste conversion systems feed gas into the current pipeline system. That gas would otherwise dissipate in the atmosphere.

Finally, switching to cleaner burning natural gas has improved our air quality. The U.S. Environmental Protection Agency (EPA) released its new Inventory of U.S. Greenhouse Gas Emissions and Sinks. It shows that annual greenhouse gas emissions (GHG) from the natural gas distribution system declined 69 percent from 1990 to 2019. During this same period, natural gas utility companies added more than 788,000 miles of pipeline to serve 21 million more customers.

Thankfully, lawmakers acted wisely and set the issue aside. There is just too much at stake to act hastily.

APRIL SAFETY MONTH — CALL BEFORE YOU DIG (Cont.)

Neglect one simple step and you could dig yourself into deep trouble. So “call before you dig.” It’s the law.  This one simple step can prevent damage, service disruptions, and potential disaster from uncharted digging into buried service facilities.  It’s the law for all of us: contractors, excavators, and homeowners.

Each utility sends employees to locate underground lines near the project with color-coded paint that identifies what kind of utility is underground. Failure to call and receive necessary guidance can prove messy at the very least, disrupt essential services, and may be downright hazardous. Everyone, including homeowners, must call when planning to dig. Neighborhoods, especially new ones, have extensive utility lines crisscrossing under their yards.

Here’s what happens next after you call to have underground utilities located.

  • A utility locator comes out to your home or business.
  • The contractor locates natural gas and utility lines on your property—for free.
  • The contractor uses visual markers to identify the lines so you know where it’s safe to dig, and areas you should avoid.

Each state or province in our region has its own convenient number for its location service:

OREGON

Oregon law created a statewide, one-call service – (800) 332-2344 or simply 811.  For more information, you can also visit online www.callbeforeyoudig.org/oregon/.

WASHINGTON

In Washington, you can call (800) 424-5555 or 811.  For additional online information, visit www.callbeforeyoudig.org/washington/.

IDAHO

Idaho has established it’s Digline service which you can reach at (800) 342-1585 or 811, with a Digline website www.digline.com.

BRITISH COLUMBIA

British Columbia has its own easy-to-use “BC 1 Call” service at (800) 474-6886 or visit the website at www.bc1c.ca.

Finally, once the utilities have been to your home or business and marked any underground utility lines – RESPECT THE MARKS.  Don’t dig within 12-inches of the markings.  Also, below is a handy chart for understanding what the different colored markings identify:

Stay Safe – Call before you dig

811 is the LAW.  Digging a new flower bed or garden – Call 811. Even if it is just a small flower bed? How about installing a post call 811.  Is it any different if you hire a landscaper or contractor?  No – call 811.

Even if you are worried about slowing down your project, please call 811.  Safety.  Safety.  Safety.  Digging without knowing the approximate location of underground utilities.  What gets damaged?  Natural gas pipelines.  Electric lines.  Phone, internet, and other communication cables.  Water lines.  Sewer lines.  This can result in service disruptions to your own home or business, and your neighbors, as well as serious injuries and costly repairs.

You may not know, but according to data collected by Common Ground Alliance (CGA), an underground utility line is damaged once every six minutes nationwide because someone decided to dig without first calling 811.

CALL BEFORE YOU DIG.  Please.  It is actually federal law to call 811 at least two business days before digging.

Every time you dig follow these steps:

  1. Notify – call 811.
  2. Wait – utilities will do the marking in 2-3 days.
  3. Confirm – that all of the affected utility operators have responded to your request by comparing the marks to the list of utilities the one-call center notified. If they are, dig safely.  If not, call again.
  4. Respect the marks – State laws generally prohibit the use of mechanized equipment within 18-24 inches of a marked utility, which is called the “tolerance zone” (click here for information from your state).
  5. Dig Safely – Avoid digging near the marks (within 18-24 inches on all sides, depending on state law), or consider moving your project to another part of your yard.

Making a call to 811 is the easiest way to make sure you keep you and your neighbors safe!!!

NWGA Guest Blog:  Renewable Hydrogen Helps Natural Gas Advance Clean Energy in the Pacific Northwest

From the Partnership for Energy Progress (PEP)

Please enjoy the following article from PEP that can also be found at https://www.pepnw.org/renewable-hydrogen-helps-natural-gas-advance-clean-energy-in-the-pacific-northwest/.

How will natural gas infrastructure advance the goal of clean energy in the Pacific Northwest? One of the most promising new technologies is called Renewable Hydrogen.

Renewable Hydrogen – or “green” hydrogen – is created by utilizing excess wind, solar or hydroelectric power to separate water molecules into hydrogen and oxygen. This process, called electrolysis, then delivers hydrogen into natural gas pipelines and releases the oxygen into the air. Renewable Hydrogen acts just like battery storage for excess renewable electricity. It captures the excess power so we can use it when the wind isn’t blowing and the sun isn’t shining, and it helps balance energy need with energy supply.

Europe has embraced Renewable Hydrogen as a key component to advancing its goal of eliminating carbon emissions, but it has been slow to catch on in the U.S. Until now. The Biden Administration has committed billions in new Research & Development funds to advance Renewable Hydrogen and projects are starting to be developed right here in our own backyard.

In Washington, Douglas County PUD broke ground on March 8, 2021, on a new Renewable Hydrogen pilot project near Baker Flats, East Wenatchee, that will support their Wells Hydroelectric Project. This project was made possible through SB 5588, bipartisan legislation that passed the Washington State Legislature in 2019 and was signed by Gov. Jay Inslee. Also in Washington, Puget Sound Energy will be conducting a series of pilot projects at their Georgetown Training Facility. Teams will perform a series of tests using different hydrogen/natural gas blends and test the system for leaks, air quality after combustion, gas quality, and impact on the appliances used.

In Oregon, NW Natural, Eugene Water & Electric Board (EWEB), and Bonneville Environmental Foundation signed an agreement in October of 2020 to collaborate on a proposed Renewable Hydrogen plant in Eugene. With the growth of wind and solar generation, along with existing hydroelectric generation, EWEB says it periodically has an abundance of renewable electricity available that can be used to produce hydrogen that can be stored for months or even years in existing natural gas infrastructure. Last year, NW Natural began testing a 5% hydrogen blend of natural gas to evaluate impacts on the system and end-use equipment performance at its Sherwood Operations and Training Center. In 2021, they are expanding blend testing to include additional end-use equipment performance on furnaces, fireplaces, and water heaters.

The 75,000 miles of existing natural gas infrastructure is a vital component to delivering clean energy in the future. As we’ve learned in the Pacific Northwest recently, having the electricity go out in a storm can be made more bearable with a reliable natural gas system that allows us to continue to heat our homes and cook for our families.

Countries around the world are embracing Renewable Hydrogen as a key component of their carbon emissions goals. By preserving and expanding our own natural gas infrastructure here in the Pacific Northwest, we can ensure we have clean, reliable power in the future.

The Natural Gas System is Inherently Resilient

The natural gas system is structurally and empirically resilient, which was graphically demonstrated in Oregon’s February Ice Storm 2021, showing that while even as tens of thousands of homes lost electricity, homes with natural gas continued to have heat, cooking, and hot water.

The inherent resiliency of the natural gas system can be attributed to several factors:

  • Planning and preparation: in combination with the physical properties of natural gas results in few operational issues that threatened supply or capacity.
  • Underground Facilities: the extensive underground location of facilities protects them from weather impacts.
  • Line Pack: transmission pipelines incidentally store gas at pressure (called “line pack”) which provides a buffer that can mitigate the effects of abnormal operating conditions.
  • Network Reliability: the network configuration of the pipeline industry means that, in the event of an outage, there is usually a “work-around” that allows continued service to LDCs and directly connected consumers.
  • Confined Impact: the physical configuration of gas pipelines limits the impact of a disruption; not susceptible to “cascading events” such as those on electric transmission systems.

The resiliency of the natural gas system was especially important during the Oregon Ice Storm. Natural gas is the workhorse fuel for homes in Oregon. For example, NWGA member company NW Natural serves 2.5 million people in 140 communities while delivering more energy than any other utility in Oregon. NW Natural also heats 74 percent of the residential square footage in its service area and provides 90 percent of the energy needs for residential space and water heat on the coldest winter days. It should also be mentioned that it does all of this at great savings to Oregon families: for the typical residence in Oregon, natural gas can be 50+ percent cheaper than electricity to heat both their home and water.

Ice Storm 2021 that electricity and natural gas are not either-or, but both-and. The resiliency of the natural gas system and its broad distribution system (in addition to natural gas inherently being a low-carbon, low-emission clean fuel) make it an essential, unavoidably necessary part of a low-carbon energy future in the Pacific Northwest.
