Earth Day Decarbonization: Three Ways We’re Helping Customers to Reduce Carbon Footprints

         Greg Polce | Vice President of Marketing – Cold Chain

          Emerson’s Commercial & Residential Solutions Business

April 22 marks the 52nd anniversary of Earth Day — a day when the world pauses to reflect on the shared responsibilities of preserving our natural environment and reversing the negative impacts of climate change. This year, the Earth Day organization is calling for global governments, businesses and citizens to form partnerships and accelerate solutions focused on building more sustainable and prosperous futures. At Emerson, we’re committed to doing our part by helping our customers to achieve their short- and long-term decarbonization goals.

According to current estimates, 51 billion tons of greenhouse gas emissions (GHG) are released annually into the Earth’s atmosphere. As the demand for energy is estimated to double over the next 30 years, climate experts are prioritizing efforts to help reduce global carbon emissions to a net-zero footprint by 2050. Hitting these decarbonization targets will require a holistic re-evaluation of everything that contributes to harmful GHG emissions.

Emerson’s commercial and residential solutions play key roles in this monumental effort. Consider that 19 percent of total carbon emissions can be attributed to feeding the world, yet roughly one-third of the global food supply is wasted. Generating, delivering and consuming electricity (by plugging things in and turning them on) accounts for 27 percent of total GHG emissions.

Three paths to net-zero

When we look at our cold chain business, we’re embarking on numerous strategies to help our customers affect positive change and provide much-needed GHG reductions. It’s important to think of these strategies as interrelated efforts that work together toward winning the race to net zero.

  1. Reducing food waste (in storage and on the move)

Reducing food waste is a core value of our cold chain business, and we help our customers to achieve this through a combination of compression technologies, tracking/monitoring devices and software, and control devices. Energy-efficient Copeland™ compressors set the industry standard in reliability and are preferred in commercial refrigeration, transport and marine applications. They serve as the cooling foundation for supermarkets, restaurants and shipping companies seeking to preserve food quality and safety and extend perishable shelf lives.

We’re also helping our customers to achieve “farm to fork” visibility to their perishable cold chains. Our GO real-time tracking and logging devices, combined with Oversight software, allow stakeholders to monitor the temperatures and locations of in-transit perishable shipments in real-time. In addition, our customers can leverage a variety of control devices to monitor coolers, freezers and cold storage facilities. The data we’re gathering from each step is delivering the deep insights our customers need to continually refine and improve their cold chain management capabilities. Once food waste reaches landfills, our Vilter™ compressors are helping operators to convert methane gas to energy.

  1. Lowering carbon emissions (from equipment and systems)

Refrigeration is among the most important technological advancements contributing to human health and well-being. Because the compressors and components that power commercial refrigeration systems consume significant amounts of electricity, Emerson has always prioritized efforts to improve equipment efficiency and reliability. From energy-efficient compression technologies with variable-capacity modulation to dedicated smart controls for low-GWP refrigerant systems, we’re innovating the tools our customers need to minimize indirect GHG emissions (from systems being powered up).

Of course, direct emissions from refrigerant leaks are also a critically important sustainability consideration. Emerson has helped lead the industry’s transition to lower-global warming potential (GWP) refrigerant technologies, supporting the global phasedown of high-GWP hydrofluorocarbon (HFC)-based systems. By embracing the next generation of low-GWP natural and synthetic refrigerants — and supporting advanced leak detection programs —we’re providing the guidance our customers need to help align refrigerant decisions with their sustainability objectives.

By combining low-GWP refrigerants with energy-efficient refrigerant technologies, we’re helping our customers to reduce both their direct and indirect emissions, which lowers the total equivalent warming impact (TEWI) of their refrigeration footprints.

  1. Enabling grid interactivity (leveraging our install base to reduce consumption)

We anticipate that the trend toward electrification will impact the ways in which we live and conduct business over the coming decades. At Emerson, we see this as a tremendous opportunity to move the needle toward net-zero by empowering our commercial refrigeration customers with grid-interactive facilities. As demand increases over the next 30 years, the infrastructure supporting our shared grid will need to be upgraded to integrate more renewable, alternative and distributed sources of energy. Although this strategy is essential to achieving net-zero by 2050, experts expect intermittent supply challenges, especially during peak consumption periods.

Today, our customers represent approximately 30,000 MW of electrical load. With grid-interactive building management controls — such as our new Lumity™ E3 supervisory control system — we’re helping them to manage their electrical footprints in coordination with utilities to offset grid demand constraints and reduce energy consumption. This will allow companies to leverage their facilities’ refrigeration, HVAC and lighting systems as distributed energy resources (DERs) — a connected technology that responds to grid signals and/or requirements to generate or conserve energy.

Not only is this strategy good for decarbonization, but we see it as an opportunity to grow our customers’ bottom lines. By connecting to the grid and reducing consumption upon request — or temporarily flexing their loads to other sources — companies can monetize their DER contributions. And while this may seem like the next frontier of energy management, many of our customers are already receiving incentives from utilities for making energy-efficient equipment choices or acting as a DER.

At Emerson, we know that the transition to net-zero will not be easy and can present new challenges to our customers and served industries. But we’re committed to achieving Earth Day goals every day of the year and look forward to helping our customers make the shift to more sustainable refrigeration and flexible energy management strategies. We’ll continue to explore ways to reduce energy consumption, lower GHG emissions, and enable grid interactivity — without impacting critical refrigeration, heating or lighting requirements.

Retrofit and Remodel Strategies to Achieve Lower-GWP Refrigeration

Andre Patenaude | Director – Solutions Integration,

Emerson’s Commercial and Residential Solution’s Business

Three decades ago, supermarket operators had few options for selecting environmentally friendly refrigeration strategies. Now, as they look to retrofit or remodel older systems to comply with environmental regulations or achieve corporate sustainability goals, operators face an expanding selection of refrigeration architectures driven by the transition to lower-global warming potential (GWP) refrigerants. In a recent article that was published in Contracting Business, I explored several options that are available to supermarkets seeking a path to low-GWP refrigeration.

Lower-GWP refrigerant options continue to proliferate

Refrigerant selection is one of the most influential factors in a retrofit or remodel strategy, often serving as an underlying process to help operators achieve corporate sustainability goals. But refrigerant selection also dictates everything from refrigeration architecture to servicing requirements to the total cost of ownership (TCO).

As the U.S. continues to phase down the use of high-GWP refrigerants and phase out those with ozone depletion potential (ODP), manufacturers are beginning to utilize a variety of alternative refrigerants that offer varying degrees of GWP reduction. Of those that are considered both safe and approved for use, the following offer distinct advantages in support of sustainability:

  • R-448/449A (low-GWP option) — Designed as a substitute for R-404A, R-448A offers a 65% reduction in GWP.
  • R-513A (lower-GWP option) — R-513A, a substitute for R-134a, delivers a 56% reduction in GWP.
  • A2L and A3 (lower- to lowest-GWP) — Mildly flammable A2L and flammable A3 (aka R-290 or propane) refrigerants are primarily used in self-contained systems and offer some of the most significant GWP reductions, and are some of the lower and lowest GWP options currently available,
  • CO2 aka R-744 (lowest-GWP option) — Used only in systems designed to handle its unique properties, R-744 is a natural refrigerant with a GWP of 1.

Upgrading for a more sustainable future

Retrofitting or remodeling a refrigeration system to improve sustainability or comply with regulations is not simply a matter of selecting a lower-GWP refrigerant. Operators must also evaluate different refrigeration systems to determine how to meet their sustainability objectives and select a system that aligns with their operational priorities. At Emerson, we refer to this process as the Six S’s of evaluation criteria:

  • Simple — to own and operate
  • Serviceable — aligns with maintenance and operations capabilities
  • Secure — provides safe operation and data security
  • Stable — delivers reliable, dependable performance
  • Smart — is equipped with electronic controls and connectivity to provide operational data and insights
  • Sustainable — from financial, technical and environmental perspectives

In terms of retrofits and remodels, the following architectures are emerging as the leading options for meeting the wide range of operator preferences:

  • Retrofit to R-448A/R-449A in existing centralized direct expansion (DX) systems — Replacing R-404A with R-448A allows operators to achieve significant sustainability improvements while preserving their existing system investments.
  • Remote/outdoor condensing units (distributed) — Remote condensing units offer installation flexibility and reliability while using low-GWP R-448A. They are ideal for small, urban store formats or for large supermarkets deploying new refrigeration capabilities outside of their existing DX systems.
  • Distributed systems — Operators can install multiple mini-racks or scroll packs in proximity to different refrigerated sections of a store. Using R-448A in this architecture can significantly reduce overall refrigerant charge while providing increased system reliability and energy efficiency.
  • Macro-distributed systems (self-contained) — Used in large cases that integrate a single compressor, refrigeration circuit and electronic controls present a simple, flexible, stand-alone option for retrofits and remodels. This approach can be scaled from one to multiple units.
  • Distributed scroll booster — This emerging distributed architecture uses low-pressure, lower-GWP R-513A for low- (LT) and medium-temperature (MT) circuits. A distributed scroll booster delivers improved energy efficiency and high reliability without added service complexities.
  • CO2 transcritical booster — A CO2 transcritical booster system is an environmentally friendly alternative to high-GWP, centralized DX systems. While this architecture uses the refrigerant CO2 (R-744) for LT and MT loads, its unique performance characteristics increase both system complexities and TCO.

Ready to meet current and future needs

The decision to retrofit or remodel a refrigeration system must be made with a long-term perspective. Operators should expect to get 20 to 30 years of service from their refrigeration systems with proper maintenance and care. But the uncertainty caused by shifting environmental regulations, changing consumer expectations and ever-evolving technologies can complicate the planning process.

Emerson is committed to providing operators with the tools and insights to meet this challenge head-on. We offer an array of compressors, condensing units, case controls and facility management technologies that can help operators to meet sustainability goals, comply with evolving regulations, and reduce the total equivalent warming impact (TEWI) of their refrigeration systems. We are also creating solutions that enable operators to make the transition to lower- and lowest-GWP refrigerants in ways that support their sustainability initiatives and long-term goals.
