District energy in a climate-uncertain future

With climate change and its clear and present danger upon us, communities must act to embrace resilient energy infrastructure and prepare for a future in a very uncertain climate. Extreme weather events, like the unprecedented cold weather in the midwestern and southern regions of the United States in February 2021, and Superstorm Sandy in 2012, have devastated people living in these areas, presented major challenges to the nation’s energy systems, and driven resilience to the forefront of national conversation – not to mention the extensive financial response required to recover from these events.

While pursuing new energy technologies and solutions is critical to our eventual success as a society, we must balance this future-looking approach with an emphasis on strengthening existing infrastructure and cost-effectively protecting citizens and current energy networks. District energy is a proven energy delivery framework that is resilient, affordable, scalable, and already utilized by grids across the country. With underground carbon steel pipes, insulated and encased in concrete, and fed by central energy facilities, district energy is, by its very construction, extremely resilient. It has the added benefit of enabling a rapid shift to renewable sources and other green energy approaches. Based on these key attributes, district energy is a key component of the solution to our climate-uncertain challenges.

What we’re up against

Since the 1980s, there has been a significant increase in the number and severity of U.S. power outages due to extreme weather. February’s unprecedented winter outages in Texas are just the latest example. Millions of Texans were without power or heat when about half of Texas’s electricity generation was offline. As a result, fuel supplies were slowed by frozen natural gas lines, some towns had to turn off their water supply, and carbon-monoxide exposure skyrocketed when many Texans turned to home generators to keep the heat and lights on. Last year was a record-setting one for wildfires, with over 10 million acres burned nationwide, leading to $20 billion in costs and damages. A decade ago, in 2012, Hurricane Sandy left much of New York City without electricity for days, in addition to causing flooding that shut down power plants and fuel refineries. 117 people were killed, and 8.5 million Americans were without power.

In addition to severe disruptions of everyday life and threats to the health and welfare of residents, these events are costing Americans dearly. According to the National Oceanic and Atmospheric Administration, climate disasters have cost the United States over $1.875 trillion since 1980. The United States cannot afford to continue to operate such vulnerable utility infrastructure, especially as the situation continues to escalate. Americans are paying in tax dollars, and – more importantly – in lives, every moment that goes by without the prioritization of resilience in our nation’s energy infrastructure.

Many communities have already officially recognized the need to put energy resilience at the very center of civic planning. For example, in 2020, Maryland launched the Resilient Maryland Program to fund innovation around energy resilience and distributed energy resources. The Massachusetts Division of Capital Asset Management and Maintenance has a specific resilience program in place to protect key infrastructure from the effects of climate change. And last fall, the city of Philadelphia hired its first Chief Resilience Officer; someone whose entire mission is to ensure that the city’s resources can withstand the impacts of climate change.

How district energy models resilience now

While acknowledging the problem is certainly the key first step of progress, and research toward future improvements is more than necessary, what can communities do right now to protect citizens from the climate disasters that are sure to come at an increasing rate? One solution is district energy.

District energy uses a centrally located facility to generate thermal energy – heat, hot water, or chilled water – for a number of nearby buildings that form an “energy district.” Microgrids, such as can be found at colleges, hospitals, airports, and office parks, are examples of district energy arrangements. District energy offers multiple benefits to its users, including freedom from asset ownership and maintenance and corresponding costs, and price stability. Most important to this issue, however, is that district energy provides energy islanding capabilities that offer far greater resilience than broader-reaching conventional utilities.

For example, during Hurricane Sandy, Princeton University relied on its own microgrid, allowing the university to maintain power and resources while the rest of the city was offline. In fact, Princeton was able to offer emergency workers and the general public a place to warm up, charge their phones, and access the internet, since they were not reliant upon the town’s non-functioning energy supply.

How is district energy so resilient? One major factor is that the generation facilities are often located in urban centers, within or nearby to the grids they serve, as opposed to energy needing to be transported over hundreds of miles from a major power plant. These microgrids can then operate autonomously, even if those around them are without resources.

In addition to proximity, many district energy systems are able to ‘blackstart’ – that is, they can restore operations independently without relying on an external source to recover from a shutdown. Because of this ability to island and blackstart, some district energy systems have upwards of 99.99% reliability, making them desirable infrastructure in an increasingly climate-uncertain world. In fact, many major American military facilities, including Fort Bragg and Andrews Air Force Base, operate on district energy systems due to its superior energy resilience and security.

How district energy can contribute to a greener future

In addition to helping protect communities from devastating climate events right now, district energy can help pave the way to a greener future, in which global warming is addressed and the effects of climate change limited, to help reduce the number of climate-related disasters to begin with. Here are some key ways district energy helps reduce carbon footprints:

  • Reduces primary energy consumption for heating and cooling by up to 50%
  • Many district systems integrate Combined Heat and Power (CHP), which has an average efficiency of 75%, compared to 50% for traditional generation methods (significantly offsetting carbon emissions that would have been emitted through conventional means)
  • A diversity of buildings (such as commercial buildings with daytime use and residential buildings with more evening use) in a district can lead to waste energy sharing and load balancing
  • Central district energy facilities can be easily electrified. Once switched over to new renewable fuel sources and/or technologies, all buildings that are part of the district system will benefit from the carbon footprint reduction instantly, since they are all connected to the same generation facility

Fortunately, the world is catching on to these benefits. The United Nations launched the District Energy in Cities initiative to encourage urban centers to take advantage of the greening power of district energy to help reduce cities’ carbon footprints and thus their contributions to climate change. Campuses, hospitals, and research facilities around the country are already relying on district energy to both meet current energy security needs and to do their part in working toward a greener future.

It’s not always the case that the technology that can help us stay safe now is the same technology that can help us move systemically in the right direction. In the face of a danger as pressing and dire as climate change, we’re fortunate to have that present and future solution in district energy.

BNN News Interview with Matt O’Malley Vicinity Energy

In this interview with Boston Neighborhood News Network host Faith Imafidon, Vicinity’s Chief Sustainability Officer Matt O’Malley discusses how eSteam™ is revolutionizing district energy by providing steam with heat pumps and electric boilers, rather than cogeneration or gas boilers.

White paper: Revolutionizing urban sustainability

We’re amid an energy transformation driven by a mounting global crisis: climate change. Across the world, we are experiencing more extreme weather events due to accelerating levels of atmospheric greenhouse gas emissions. Mitigating carbon in the production and distribution of energy is now just as critically important as our society’s ever-growing need for energy itself. It’s clear that we need resilient, reliable and agile energy solutions…now. 

District energy systems, like Vicinity’s, are uniquely positioned to take advantage of existing infrastructure in conjunction with critical technological advancements to cost-effectively decarbonize quickly. This white paper highlights the benefits of district energy in a decarbonizing world, specifically how electrifying district energy can help urban centers rapidly and affordably achieve city and state carbon reduction goals.

Boston Mayor Michelle Wu Kicks off Vicinity Energy’s electrification plans

Boston Mayor Michelle Wu helped kick off our electrification plans with the deconstruction of the steam turbine at our Kendall Green Energy Facility, paving the way for the installation of our new 42 MW electric boiler.

This monumental step forward accelerates our efforts to reach net zero carbon emissions and offer carbon-free eSteam™ to our Boston and Cambridge customers.

Reimagining the energy industry: an inflection point for decarbonization efforts

As a coastal city, Boston is particularly vulnerable to the negative and real impact of climate change. Over the next several decades, according to a new report from the University of Massachusetts Boston, this region will almost certainly see hotter days, increasingly intense storms, and rising sea levels. Current guidance coming out of local and state government – such as Boston’s updated Building Emissions Reduction and Disclosure Ordinance (BERDO 2.0), which sets requirements for large buildings to reduce their energy and water use data, stretch codes which are mandated so buildings will achieve higher energy savings, and growing investments in green and renewable energy technologies – are prescriptive policies that will help lower greenhouse gas emissions and hopefully slow climate change’s tide.

Still, with the recent Supreme Court decision curtailing the EPA’s authority to regulate greenhouse gas emissions, achieving a 50 percent drop in emissions by 2030 or a net zero future with the remaining tools from a federal regulation standpoint will be increasingly challenging. This ruling affirms the local business community’s role in achieving net zero, particularly in Greater Boston. In a way, it is an opportunity for creative solutions to drive what needs to be done.

Coming from the government world, I am excited to be part of the solution. And with 2022 now at its midpoint – an inflection point regarding how environmental progress will be achieved locally and nationally, I thought I would share an update on the state of play from our perspective.

Recently there’s been momentum in the environmental world regarding the usage of old technology with an innovative, fresh lens. For instance, cargo bikes are an efficient and environmentally friendly method for making last-mile deliveries. A study last year by Possible, a British advocacy group, found that electric cargo bikes cut carbon emissions by 90% compared with traditional diesel vans and by a third compared with electric vans, according to the report. Air pollution was also significantly reduced. The bikes also delivered approximately 60% faster than vans in urban centers, had a higher average speed, and dropped off ten items an hour, compared with six items for vans. Meanwhile, unlike plastic, glass bottles are a fully sustainable and recyclable resource that also provides fantastic environmental benefits like a longer life cycle and lower carbon footprint. It is also made of natural raw materials and has an enhanced ability to preserve food.

This is precisely what we are doing at Vicinity. In April, we announced the launch of eSteam™, an innovation designed to rapidly decarbonize the highest source of emissions in major cities and commercial buildings. Our company is the first in the U.S. to electrify our operations, offering renewable thermal energy by installing electric boilers, industrial-scale heat pumps, and thermal storage at our central facilities starting in Boston and Cambridge, with other locations to follow.

In cities like Boston and Cambridge, buildings account for nearly 70% of all greenhouse gas emissions. Think about how changing the fuel source can have a profound impact, whether on coal, oil, natural gas, or combined heat and power (CHP) plants. Now is the time to transition from natural gas to renewable, clean energy. That is precisely what this new electrified system will be able to accomplish: modernizing how district energy is approached.

If we are serious about decarbonization, we must be bold and reimagine our industry. That’s what is being done at Vicinity Energy, and we are looking to best practices from similar steam loops in other parts of the world. Copenhagen, Malmö, and Drammen use district energy to meet and surpass their respective climate goals. Our goal is to be the first in the U.S. to lead in this space. Vicinity is uniquely poised to serve as a national leader in building decarbonization. The time for action is now. Our customers want it, our cities ask for it, and our planet demands it.

We are proud of what we are accomplishing.

eSteam™: a new, greener solution to combat carbon emissions

Many people are aware that pollution is a harmful downside to urbanization. What you may not know, however, is that 90% of our world’s population breathes polluted air every day, and 7 million people die from exposure to this contaminated air every year. This is a jarring statistic, and it sheds light on how carbon emissions serve as a silent killer in our world as the air we breathe can quickly and quietly turn lethal.

What is causing this?

Various factors contribute to pollution and climate change around the world. So, what are the biggest culprits, and how do they produce these carbon emissions? Building operations are responsible for 27% of global CO2 emissions each year, with another 20% coming from the construction and building materials required to create and maintain a building. These daily operational emissions generate lighting, heating, and cooling for a building, all essential elements of residential and commercial life. Additionally, many of these carbon emissions from buildings result from desperation to meet growing energy demands in conjunction with a lack of available clean energy options, as most of these establishments are several decades old.

What can be done?

One way to combat the increasing levels of carbon emissions within buildings is to integrate renewable energy systems into existing architecture through renovation and retrofits. It is equally important to ensure that new buildings’ systems are centered around using clean energy. Commonly known renewable energy sources include wind, solar, and hydroelectricity, and while these have proven to be effective in numerous circumstances, another, more cost-effective solution exists. eSteam™ generates power without emitting any CO2 and is the first-ever renewable thermal energy product in the United States!

Customers benefit from carbon-free eSteam™ generated with renewable electricity.

How eSteam™ works

Instead of fossil fuels, eSteam™, a new offering from Vicinity Energy, is fueled by electricity in a process known as electrification. Electric boilers, thermal storage, and industrial-scale heat pumps are installed at central facilities to generate steam. These devices employ renewable power from other carbon-neutral energy sources such as wind, solar, and hydro to produce energy used to power buildings in cities across the country.

Rather than start from scratch with sustainable infrastructure, eSteam™ leverages and builds upon existing infrastructure. This means that older buildings do not need significant investments to decarbonize their thermal energy load. eSteam™ uses Vicinity’s existing network of steam pipes, electric substations, and transmission lines to rapidly reduce carbon emissions. This electrification method is the most cost-effective and reliable way to accelerate the decarbonization of buildings and communities.

Benefits of eSteam™
