The pursuit of net zero emissions is not just an environmental goal; it’s a linchpin in the global strategy to combat climate change and ensure a sustainable future for all. Greenhouse gases, including CO₂ emissions, play a significant role in influencing global temperatures. When these gases are released into the atmosphere, they act like a blanket, trapping heat from the sun and warming the planet. This process, known as the greenhouse effect, is natural and necessary for life on Earth to exist. However, human activities, particularly since the Industrial Revolution, have significantly increased the concentration of these gases, leading to an enhanced greenhouse effect and, consequently, global warming.

The impact of rising temperatures is far-reaching, affecting everything from ecosystems and wildlife to human health and economies. Extreme weather events, rising sea levels, and changing precipitation patterns are just a few of the consequences that threaten our way of life and the natural world. The urgency to act is underscored by the increasing frequency and severity of these events, signaling a clear warning that immediate and sustained efforts are needed to mitigate climate change.

Net zero emissions play a critical role in this effort by aiming to halt the increase in global temperatures. According to the Paris Agreement, achieving net zero is central to limiting global warming to well below 2 degrees Celsius above pre-industrial levels and maintaining it to 1.5 degrees Celsius. This target is not arbitrary; it represents a threshold beyond which the risks and impacts of climate change become significantly more severe and potentially irreversible.

The post What are Microgrids? Alternative Energy Solutions for a Clean, Resilient Future appeared first on Bloom Energy.

The post Clean 24/7 Power For 24/7 Healthcare appeared first on Bloom Energy.

Utilities across the United States are challenged to add generation capacity quickly enough to meet the growth demands of data center customers. In many states, such as Texas and California, they are also experiencing an increasing number of service interruptions, with significant impact to business operations and the lives and livelihoods of the people in the communities they serve.

The problem is exacerbated by the fact that data center energy needs are huge, and adding new 24×7 generation sources quickly that are aligned with prevailing zero carbon and renewable policy ambitions is challenging. The system is plagued by transmission constraints, severe weather-driven resilience challenges, issues with the integration of intermittent renewables, underperforming hydro assets, planned nuclear retirements, misalignment of biogas incentives, and virtually no zero-carbon options.

Natural gas fuel cells

AWS selected the onsite, solid oxide fuel cell technology to provide distributed energy to three proposed data center sites in Oregon requiring 24.3 MW at each location. AWS learned that the local utility could not add capacity in time. It chose solid oxide fuel cells that convert natural gas to electricity without combustion, with a 99 percent decrease in smog-forming pollutants and water use and 50 lower carbon emissions than the displaced grid power in the region.

Further, the fuel cells have a minimal footprint or infrastructure at the location of the data center, reducing the need for transmission lines or related materials and the associated energy losses, costs, and fire risks that come with such transmission.

We all want to get to net zero carbon emissions. Natural gas fuel cells are an interim solution

It’s time to embrace a solution such as fuels cells to support the growth profile as we balance need with available resources. Chicago-based Arizton’s, a research firm, issued a report last year that said the US data center construction market is expected to have a compound, annual growth rate of about 3.5 percent during 2022-2027. It cited the growing popularity of IoT, the emergence of 5G networks, and the demand for streaming online entertainment content at high speeds as the major factors driving the growth of the US data center market. The use of cloud computing services and applications will also continue to grow at over 30 percent CAGR , leading to further development of large hyperscale cloud-based data centers.

We all want to get to net zero carbon emissions as fast as possible. We all want to have energy supplies to meet our needs for a prosperous and health society. We are making progress towards these mutually inclusive goals, starting with new interim solutions that help meet today’s quickly evolving needs with tomorrow’s promise.

The post Data centers and fuel cells appeared first on Bloom Energy.

We couldn’t have done that that fast in the past, but we were able to do so at Ferrari because of a significant change to the way we make and install our fuel cells. We can now deliver them as a system with built-in connections so they can be quickly joined to fuel sources and the facility that needs clean, reliable power. No more trenching, no more backfilling, no more praying for a stretch of good weather so installers can pour a concrete pad for the fuel cells to sit on.

The changes we have made could be easily overlooked by the casual observer because the boxes, which are about the size of a refrigerator, haven’t changed much in appearance. But they mean that the days of Bloom Energy putting in nine to 12 months of preparation work before a power-up are over.

In the past, construction crews had to locate and mark underground utilities; demolish and remove existing hardscape; rough-in and test utility hook-ups; pour a concrete pad and, once it was dry, lower the Energy Servers onto it. They then had to pull through and connect the utility lines, tie everything into the facility, and clean up.

Bloom’s site supervisors had to make multiple trips to check on the work of the local, specialized general contractor. The work also required multiple skilled trades, inspections, the presence of emergency response crews and permits. It was a lot of variables to manage and a lot of costs, which could differ greatly from one location to another. It has been a definite hit to our bottom line.

And so we began to think about how we could do things differently. How could we make the installations simpler, less disruptive for customers, and more cost effective? We looked at all the variables in our control and brainstormed ways to standardize them.

What we came up with was putting the Energy Servers on an additional base, a metal frame with power and ancillary modules already in it, fitted out and tested by the workers at our Delaware and California plants before being delivered to the job site. The whole assembly, which we call Packaged Energy Servers, can now be set on a compacted aggregate surface that can be prepared by any general contractor, and its above-ground cable trays can be connected to a substation by one tradesperson. We’re eliminating the concrete and asphalt our installation used to require, sharply reducing both that cost and the greenhouse gas emissions from those materials. Since late 2020, we have made more than 20 Packaged Energy Server installations.

The new approach works for both our solid oxide fuel cells and our electrolyzers, and the Packaged Energy Servers can support microgrid usage by adding a DC cable tray on top of the existing AC tray. We’re future-proofing the Packaged Energy Servers in other ways, too, to continue to drive down costs and increase margins as demand for our technology increases. That includes getting UL listing for the entire Packaged Energy Server assembly, which will further simplify permitting with local authorities.

Manufacturing our fuel cells on ready-to-install platforms is clearly better for Bloom Energy’s customers: They will get their power on faster, without big disruptions at their site or under the ground. There will be fewer permitting delays or construction headaches. If customers need clean, reliable power for only a short time, they can get an installation that meets that need. If they need to rapidly scale up their power supply, they can quickly add additional Packaged Energy Servers without disruptive digging that could damage the modules that are already there.

Ready-to-install platforms are also better for Bloom Energy and its investors. The more installation variables we can address and resolve in our factories, the fewer unplanned costs we will face on the job site. In the past, roughly 60% of the total installation cost for our fuel cells was in site construction. We have calculated that, by using these platforms, we decrease installation costs by about $499 per kilowatt. With our installations getting larger, the cost savings could be significant. Packaged Energy Services also make it possible for Bloom to recover its servers when the client’s lease or pilot test is over, or if their credit situation or location changes.

As I like to tell all of my colleagues at Bloom, it’s the most beautiful install possible.

The post How Bloom Energy Is Delivering Power Faster With Less Site Work, Lower Costs appeared first on Bloom Energy.

Biotechnology and pharmaceutical manufacturers are increasingly susceptible to costly power disruptions.

In 2018, Hurricane Florence devastated the Carolinas, causing record flooding, wind gusts exceeding 100 mph, and over $16 billion in damages in North Carolina alone. The extreme winds felled trees, downed power lines, and forced hundreds of thousands to evacuate. But they also impacted manufacturing operations in the state.

Pfizer, a multinational pharmaceutical and biotechnology corporation, was forced to halt production at a key injectable drugs facility in North Carolina. Merck & Co. and Novartis also suspended operations in the state due to the storm.

Extreme weather events like Hurricane Florence have become increasingly common. And it’s not just regional areas where hurricanes, snowstorms or wildfires are more likely. Across the nation, outages caused by extreme weather events increased 70 percent between 2010-2019 over the previous decade.

Biotechnology and pharmaceutical manufacturing facilities are extremely vulnerable to interruptions in power. These types of buildings are vast, complex and resource-intensive, requiring critical elements such as around-the-clock temperature and air quality control to protect the highly sensitive nature of their products. Such structures are costly to build, operate, and maintain even before factoring in the cost of any unplanned downtime.

Grid-related power disruptions are one of the most pressing challenges threatening manufacturers today. Worse, these power events often lead to expensive delays in production, and costly setbacks to research, storage, or warehousing. Shutting off and turning back on a production line is a significant cost, that’s often difficult to calculate.

Quick Stats

• Pharmaceutical manufacturers experience an average of 6-8 disruptions per year, often caused by voltage sags.
• Industry experts estimate 30-70 percent of disruptions are caused by poor power quality (Source: Rockwell Automation).
• Disruption to production in a pharmaceutical facility can cost up to $500,000 per hour of downtime, according to industry experts.

Eliminating Tradeoffs

As pharma and biotech companies look to address their critical resiliency needs, the growing ambitions of a net-zero future and the impacts of rising energy costs have elevated the importance of choice when it comes to power. Distributed generation is becoming critical to the energy transition, providing a clear path forward for those seeking to gain more control of their electricity supply.

Most distributed energy resources (DER) are self-sufficient, but they are not one size fits all. Technologies like wind and solar are great for their renewable profile but due to their inherent intermittencies, cannot practically solve resiliency challenges. Diesel generators have been the status quo back-up solution for decades. However, they are monolithic machines without inherent redundancy and produce over 40 toxic air contaminants, including a variety of carcinogenic compounds, during operation. Uninterruptible Power Supply (UPS) are also used to alleviate the effects of unexpected power disruption—for a short term, stop-gap solution. But UPS are expensive and often run on a limited supply of battery power. Resiliency decisions should not be made at the expense of environmental concerns and sustainability decisions should not ignore the importance of reliable energy supply.

What’s more, financial predictability has increasingly become top-of-mind, especially in recent months, where supply change shortages and sharply rising inflation have led to immediate and massive price surges on utility bills. These notable short-term increases have raised the stakes within an already complex purchasing environment and companies are actively looking for solutions that insulate them from this risk.

Meanwhile, many biotech and pharma companies are taking steps to implement renewable power by creating wind and solar farms.

Renewable power farms are often created in one of two ways: a company seeks to maximize sustainability with a cost-effective solar project that generates some power on-site for their operations, and is a cleaner option than the utility grid. But these projects often only power a fraction of a facility’s total kilowatt hours behind the meter.

The second option is to install a large-scale solar or wind farm off-site in a rural area, where it may send the power it generates into the grid creating Renewable Energy Certificates (RECs). These RECs can be retired against electrons still being purchased by facilities from their local utilities because there isn’t enough space onsite to remove the utility load with solar/wind. The farm generates clean energy, but the company’s facilities may still run on grid electricity.

Fuel Cell Microgrids

Fuel cells are an ideal solution for those seeking to gain more control over their electricity supply.

Fuel cells provide a critical foundation for building microgrids of varying complexity and can provide significant benefits to the communities, businesses, and utilities they are part of. This type of technology targets a customer’s 24/7 energy usage whereas technologies like solar or battery storage are intermittent.

Since fuel cells often generate power right where energy is being consumed, they can be deployed anywhere and are not dependent on the weather or encumbered by densely populated geography. Customers can tie their critical loads directly onto the fuel cells to provide UPS-quality power to avoid power quality issues as well as carry critical loads through long duration outages. For instance, Bloom’s microgrid platform powered one manufacturing center through a 5.5 day outage in California.

Moreover, our fuel-flexible platform addresses both the causes and consequences of climate change by using natural gas at the highest efficiency today, reducing water consumption and greenhouse gas emissions while improving local air quality. Plus, we are ready to advance decarbonization as renewables come online at scale.

The Solid Oxide Advantage

Solid oxide fuel cell technology, at the heart of the Bloom Energy Server, is uniquely effective in eliminating tradeoffs, providing an unparalleled combination of resiliency, sustainability, and cost predictability. It avoids the vulnerabilities of conventional transmission and distribution lines by generating power on-site, where the electricity is consumed.

Resiliency

As a critical, always-on microgrid solution, Bloom Energy Servers can operate alongside a main grid, but independently of it during a power outage. They stay online even when peak hours cause grid overload, or when distribution infrastructure is damaged—such as during Hurricane Florence. Because they receive fuel through the underground pipeline system, they are less susceptible to the impacts of extreme weather, enabling safe, continuous operation and avoiding costly consequences of unplanned downtime.

Sustainability

By converting natural gas, biogas, or hydrogen into electricity using an electrochemical reaction without combustion, we’re able to achieve an industry-leading 60 percent+ electrical efficiency while virtually eliminating NOx, SOx, and other harmful criteria pollutants from the environment.

Predictability

With the recent volatility in utility rates, low cost and predictable power are important factors for manufacturers facing cost scrutiny. Bloom Energy’s solid oxide platform not only protects against outage-related costs that can reach into the millions of dollars, but also enables customers to hedge against rate volatility and price escalation by fixing a large portion of their electricity cost, providing multiple financing options and flexible term length.
