The Cocktail Napkin of Energy Math

Mark von Keszycki — Wed, 10 May 2023 16:55:28 +0000

THE COCKTAIL NAPKIN OF ENERGY MATH

“I’m amazed at how many people still don’t realize that LCOE [levelized cost of electricity] is a misleading basis for estimating total system costs to governments, electricity consumers and taxpayers … That’s why I generally ignore it.” So begins an enlightening discussion from Michael Cembalest, Chairman of Market and Investment Strategy for J.P. Morgan Asset & Wealth Management, in his company’s 13^th annual energy paper.

Though LCOE is often used as a “bottom-line” number for evaluating the economics of wind and solar projects, Cembalest puts little stock in its usefulness.

“Levelized cost of energy is a distraction,” he says, if you’re trying to understand total system costs of electricity.” This is because, when computed for individual generation or storage technologies, LCOE does not properly take account of:

the need for backup power, storage and reserve margins to maintain system reliability
the value of electricity supplied at different times of the day or year
the need to overbuild wind and solar capacity to meet demand in deeply decarbonized systems

“In other words,” Zembalest says, “LCOE only measures the cost of a marginal MWh of wind or solar power and typically does not include any of these other capital or operating costs.”

Zembalest describes a conversation with Paul Joskow, the Elizabeth and James Killian Professor of Economics Emeritus at MIT. Joscow recounted that LCOE was originally developed to compare costs of dispatchable baseload nuclear and coal plants with the same capacity factors. LCOE, Joscow asserts, is “inappropriate for comparing intermittent generating technologies like wind and solar with dispatchable generation…and also overvalues intermittent generating technologies compared to dispatchable baseload generation.”

Real-life example

To illustrate this point, Zembalest cites a recent example from the United States. The state of Texas has an enormous amount of wind generation, and it has also experienced some extreme weather events. On Dec. 23, 2022, temperatures dropped to 13⁰-28⁰F vs average levels, causing electricity demand to spike while renewable output collapsed. The result was a massive gap that only backup power could fill.

“Natural gas output doubled,” Zembalest says, “but this was not accounted for accounted for in LCOE.” In December 2022, Texas wind capacity factors averaged 32%. “But that doesn’t mean that wind provided steady power at 32% of installed capacity,” he says. In reality, Texas wind generation varied from a low of 5% of capacity to a peak of 70% during the month.

Yet LCOE is calculated the exact same way whether Texas wind capacity factors are 32% for every hour of the month, or if they average 32% but vary from 5%-70%. In the latter scenario, backup thermal power/storage needs, and associated costs, are much higher than in the former. As for energy storage, “low wind conditions lasted for 3 days, in which case,” says Zembalest, “many billions of dollars of 4–6-hour storage would have been needed” to compensate. LCOE, he says, “is the cocktail napkin of energy math.”

Zembalest’s paper is a long but lively read, and also includes an excellent section on the scramble to reshore production and processing of energy minerals. Download it here.

BLACKROCK: BARRIERS TO THE GLOBAL ENERGY TRANSITION

Count on the leader of the world’s largest private equity fund to provide a realistic appraisal of the prospects for a global energy transition. Larry Fink, founder and CEO of BlackRock recently spoke with Jason Bordoff, founding director at the Center for Global Energy Policy at Columbia’s School of International and Public Affairs in a wide-ranging and provocative interview.

As reported by Rod Walton in EnergyTech, Fink says, “We’re really not being truthful to ourselves.” Fink acknowledges that while decarbonizing the economy could represent “the greatest investment opportunity of a lifetime,” conditions are tougher now with high inflation, interest hikes and geopolitical conflict creating headwinds.

He recognizes that the worldwide capital investment required is huge — on the order of $100 trillion by 2050, according to Walton. But, “even if that capital is deployed efficiently in developed economies, what about the rest of the world where the need for affordable electricity is even greater and the means are harder to come by … What good is all of this energy transitioning if China, India, southeast Asia, South America and Africa are still burning fossil fuels because that is the quickest and most affordable way to heat and electrify homes and businesses.”

The challenge is twofold, Fink says. First, “No one has come up with a proper solution on how we bring the emerging world forward … If we want to be faithful to [the goal of global decarbonization] we need emerging countries to come along with us.” The only way to do this, he say, is to create better technology to bring down the cost.

Also, as Walton put it, “The customer in the energy sector may want clean energy but he or she also wants abundant, cheaper energy maybe even more. And we cannot just wish away the bad old hydrocarbons. They are a bridge at the very least, and highly favored among a sizable part of the population which doesn’t align with energy transition orthodoxy.”

“We need to find ways of working together instead of talking around each other and over each other,” Fink says. “I’m an optimist on decarbonization, but … we need to make sure we include (resource) adequacy in energy policy.”

EU APPROVES WORLDS FIRST CARBON TAX ON IMPORTS

The European Union is continuing its aggressive action on climate change with the approval of first of-its-kind legislation to tax imports based on the greenhouse gases emitted to make them. The Wall Street Journal reports that the new tariffs, called Carbon Border Adjustments, “aim to push economies around the world to put a price on carbon-dioxide emissions while shielding the EU’s manufacturers from countries that aren’t regulating emissions as strictly, or at all.”

The European Commission website states, “The EU’s Carbon Border Adjustment Mechanism (CBAM) is our landmark tool to put a fair price on the carbon emitted during the production of carbon intensive goods that are entering the EU, and to encourage cleaner industrial production in non-EU countries … By confirming that a price has been paid for the embedded carbon emissions generated in the production of certain goods imported into the EU, the CBAM will ensure the carbon price of imports is equivalent to the carbon price of domestic production, and that the EU’s climate objectives are not undermined.”

Offering Clean Energy Around the Clock

OFFERING CLEAN ENERGY AROUND THE CLOCK

MIT spinout 247Solar is building high-temperature concentrated solar power systems that use overnight thermal energy storage to provide power and heat.

By Zach Winn – As Published in MIT News

As remarkable as the rise of solar and wind farms has been over the last 20 years, achieving complete decarbonization is going to require a host of complementary technologies. That’s because renewables offer only intermittent power. They also can’t directly provide the high temperatures necessary for many industrial processes.

Now, 247Solar is building high-temperature concentrated solar power systems that use overnight thermal energy storage to provide round-the-clock power and industrial-grade heat.

The company’s modular systems can be used as standalone microgrids for communities or to provide power in remote places like mines and farms. They can also be used in conjunction with wind and conventional solar farms, giving customers 24/7 power from renewables and allowing them to offset use of the grid.

“One of my motivations for working on this system was trying to solve the problem of intermittency,” 247Solar CEO Bruce Anderson ’69, SM ’73 says. “I just couldn’t see how we could get to zero emissions with solar photovoltaics (PV) and wind. Even with PV, wind, and batteries, we can’t get there, because there’s always bad weather, and current batteries aren’t economical over long periods. You have to have a solution that operates 24 hours a day.”

The company’s system is inspired by the design of a high-temperature heat exchanger by the late MIT Professor Emeritus David Gordon Wilson, who co-founded the company with Anderson. The company integrates that heat exchanger into what Anderson describes as a conventional, jet-engine-like turbine, enabling the turbine to produce power by circulating ambient pressure hot air with no combustion or emissions — what the company calls a first in the industry.

Here’s how the system works: Each 247Solar system uses a field of sun-tracking mirrors called heliostats to reflect sunlight to the top of a central tower. The tower features a proprietary solar receiver that heats air to around 1,000 Celsius at atmospheric pressure. The air is then used to drive 247Solar’s turbines and generate 400 kilowatts of electricity and 600 kilowatts of heat. Some of the hot air is also routed through a long-duration thermal energy storage system, where it heats solid materials that retain the heat. The stored heat is then used to drive the turbines when the sun stops shining.

“We offer round-the-clock electricity, but we also offer a combined heat and power option, with the ability to take heat up to 970 Celsius for use in industrial processes,” Anderson says. “It’s a very flexible system.”

The company’s first deployment will be with a large utility in India. If that goes well, 247Solar hopes to scale up rapidly with other utilities, corporations, and communities around the globe.

A new approach to concentrated solar

Anderson kept in touch with his MIT network after graduating in 1973. He served as the director of MIT’s Industrial Liaison Program (ILP) between 1996 and 2000 and was elected as an alumni member of the MIT Corporation in 2013. The ILP connects companies with MIT’s network of students, faculty, and alumni to facilitate innovation, and the experience changed the course of Anderson’s career.

“That was an extremely fascinating job, and from it two things happened,” Anderson says. “One is that I realized I was really an entrepreneur and was not well-suited to the university environment, and the other is that I was reminded of the countless amazing innovations coming out of MIT.”

After leaving as director, Anderson began a startup incubator where he worked with MIT professors to start companies. Eventually, one of those professors was Wilson, who had invented the new heat exchanger and a ceramic turbine. Anderson and Wilson ended up putting together a small team to commercialize the technology in the early 2000s.

Anderson had done his MIT master’s thesis on solar energy in the 1970s, and the team realized the heat exchanger made possible a novel approach to concentrated solar power. In 2010, they received a $6 million development grant from the U.S. Department of Energy. But their first solar receiver was damaged during shipping to a national laboratory for testing, and the company ran out of money.

It wasn’t until 2015 that Anderson was able to raise money to get the company back off the ground. By that time, a new high-temperature metal alloy had been developed that Anderson swapped out for Wilson’s ceramic heat exchanger.

The Covid-19 pandemic further slowed 247’s plans to build a demonstration facility at its test site in Arizona, but strong customer interest has kept the company busy. Concentrated solar power doesn’t work everywhere — Arizona’s clear sunshine is a better fit than Florida’s hazy skies, for example — but Anderson is currently in talks with communities in parts of the U.S., India, Africa, and Australia where the technology would be a good fit.

These days, the company is increasingly proposing combining its systems with traditional solar PV, which lets customers reap the benefits of low-cost solar electricity during the day while using 247’s energy at night.

“That way we can get at least 24, if not more, hours of energy from a sunny day,” Anderson says. “We’re really moving toward these hybrid systems, which work like a Prius: Sometimes you’re using one source of energy, sometimes you’re using the other.”

The company also sells its HeatStorE thermal batteries as standalone systems. Instead of being heated by the solar system, the thermal storage is heated by circulating air through an electric coil that’s been heated by electricity, either from the grid, standalone PV, or wind. The heat can be stored for nine hours or more on a single charge and then dispatched as electricity plus industrial process heat at 250 Celsius, or as heat only, up to 970 Celsius.

Anderson says 247’s thermal battery is about one-seventh the cost of lithium-ion batteries per kilowatt hour produced.

Scaling a new model

The company is keeping its system flexible for whatever path customers want to take to complete decarbonization.

In addition to 247’s India project, the company is in advanced talks with off-grid communities in the Unites States and Egypt, mining operators around the world, and the government of a small country in Africa. Anderson says the company’s next customer will likely be an off-grid community in the U.S. that currently relies on diesel generators for power.

The company has also partnered with a financial company that will allow it to access capital to fund its own projects and sell clean energy directly to customers, which Anderson says will help 247 grow faster than relying solely on selling entire systems to each customer.

As it works to scale up its deployments, Anderson believes 247 offers a solution to help customers respond to increasing pressure from governments as well as community members.

“Emerging economies in places like Africa don’t have any alternative to fossil fuels if they want 24/7 electricity,” Anderson says. “Our owning and operating costs are less than half that of diesel gen-sets. Customers today really want to stop producing emissions if they can, so you’ve got villages, mines, industries, and entire countries where the people inside are saying, ‘We can’t burn diesel anymore.’”

Mine Power: 9 Tips for Renewable Energy Planning

Mark von Keszycki — Tue, 24 Jan 2023 00:42:17 +0000

NINE TIPS FOR RENEWABLE ENERGY PLANNING

Ludovic Rollin, senior environmental consultant with global mining consultancy SRK Consulting, recently outlined nine key considerations for miners seeking to decarbonize their operations. In an article from Australian Resources and Investment, reprised by Australian Mining, Rollin says the first requirement is a change of mindset.

The future starts now

“Some companies are set in their ways with plant design,” he says. “They can’t see how solar, wind or hydro could power the mine. Or they incorporate a small proportion of renewables in the energy mix.” He believes this approach is partly due to a lack of understanding of potential options.

Also, they may not fully appreciate the risks. Per AM, “Rollin believes mining companies that do not consider renewable energy to power mines – particularly for new projects – face greater risks in the future.”

Without planning for renewables, Rollin says, “By the time the mine gets through the feasibility-study stage and is built, it could still be using fossil fuels as its main energy sources in 2050 … That would be a significant risk.” As more countries commit to net-zero emissions targets, miners will be under greater pressure to decarbonize their operations.

Nine tips for good practice

Here are Rollin’s nine tips for approaching the inevitable migration away from fossil fuels for powering mines:

Start early: Renewable energy should be a larger part of mine-planning discussions from day one of a project.
Aim for 100 per cent renewable energy: It might not be possible for a particular mine, but aiming for full renewable energy makes sense. This approach is more effective than trying to incorporate a small proportion of renewables into the mine’s energy mix and building from there.
Be open-minded:Recognise that renewable-energy technology is changing rapidly. Understand that cost assumptions for renewables could change as the project is planned, making capital expenditure more feasible at the mine.
Ensure you have the right internal people/external support: Assessment of renewable technology at mines requires expert skills and planning. Ensure your organisation has sufficient internal skills with renewable energy and/or access to external consultants with substantial expertise in the field.
Financiers:Understand the approach of current or potential financiers for the mining project. How do they view renewables in mining? How does implementing renewable energy at the mine affect the project’s cost of capital?
Government support:Determine if there are federal, state or local government incentives that can help decrease capital expenditure for a renewable project. Understand how governments view the potential of introducing renewables at a mine, and what it means for the local community.
Build a long-term case for renewables, beyond the mine: How many jobs will the renewable project create for the local community during and after construction? How many local businesses can the project support? How many local homes could the mine power? What are other potential uses for the mine’s excess renewable energy?
Consider renewables as part of mine closure: Discussions on renewables are important at all stages of the mine, and particularly for mine closure. How could renewables help the nearby community when the mine eventually closes?
Engage early: Renewable projects require significant support from communities, nearby industry and different levels of government. Consider what it means for the project to have and maintain a sustainable development licence to operate, and the importance of community engagement within that process.

ESG BENEFITS BEYOND MINE CLOSURE

Some forward-thinking miners are exploring ways to continue extracting value from disused sites and providing benefits to surrounding communities once mineral extraction has ended. Two recent articles on this topic caught our eye.

The first, in Australian Mining, cites the example of the former Kidston gold mine in Queensland. Once Australia’s largest open-cut gold mine, the project closed in 2001. Genex, a power company, is now transforming the site into a clean-energy hub by combining solar, wind and pumped-storage hydropower. This landmark conversion of a disused gold mine will generate enough electricity to power 143,000 homes for eight hours – and is expected to create at least 500 jobs during construction.

The Kidston Pumped Storage Project essentially turns the mine’s massive open-cut pits into a giant battery by pumping water into an upper energy-storage reservoir when energy prices are low. It then releases the water through reversible turbines into the lower reservoir to generate power when energy demand is high.

A piece from Mining.com describes how an international team of researchers is developing a novel way to store energy by transporting sand into abandoned underground mines. The new technique, called Underground Gravity Energy Storage (UGES), proposes an effective long-term energy storage solution while also making use of now-defunct mining sites.

The business model is not unlike the pumped hydro storage in the Kidston mine, but the scientific principle is different. In a paper published in the journal Energies, the researches describe a process that generates electricity when the price is high by lowering sand into an underground mine and converting the potential energy of the sand into electricity via regenerative braking and then lifting the sand from the mine to an upper reservoir using electric motors to store energy when electricity is cheap.

“When a mine closes, it lays off thousands of workers. This devastates communities that rely only on the mine for their economic output,” says Julian Hunt, lead author of the study. These two examples show how mines can offset these impacts with lasting benefits to surrounding communities while simultaneously creating new, ongoing revenue streams for themselves by repurposing otherwise abandoned assets.

EUROPE’S BIGGEST DEPOSIT OF RARE EARTHS FOUND IN SWEDEN

Tom Fisk – Pexels

Reports from Reuters and elsewhere reveal that Swedish state-owned mining company LKAB has discovered more than 1 million tons of rare earth oxides in the Kiruna area in the far north of the country, the largest known such deposit in Europe.

Rare earth minerals are essential to many high-tech manufacturing processes and are used in electric vehicles, wind turbines, and many types of electronics. Demand for rare earths is expected to rise in coming years due to a ramp-up in electric vehicles and renewable energy. However, these elements are currently not mined in Europe, leaving the region depending on imports, primarily from China, where 63 percent of the world’s rare earth mining and 85 percent of rare earth processing takes place.

Sweden’s Minister for Energy, Business and Industry Ebba Busch says in a statement “Electrification, the EU’s self-sufficiency and independence from Russia and China will begin in the mine.”

2021 Was Biggest Year Ever for Batteries

Mark von Keszycki — Thu, 13 Jan 2022 20:48:17 +0000

BIGGEST YEAR EVER FOR BATTERIES

STORAGE IS KEY TO CLEAN POWER ON DEMAND

A recent article by Canary Media’s Julian Spector highlights explosive growth in the energy storage market. This is good news for renewables, because storage is key to overcoming the intermittency of PV and wind and making clean energy a reality around the clock. Though Spector’s data is drawn from the U.S., it is representative of similar trends across the globe.

Although battery storage is needed wherever wind or PV are used – both off-grid and on-grid – Spector focuses on grid-connected applications which predominate in developed countries like the U.S. Spector begins by noting that 2021 was the biggest year ever for energy storage. He quotes Jason Burwen, interim CEO of the U.S. Energy Storage Association in as saying, “After achieving one gigawatt of annual installations for the first time [in 2020], U.S. energy storage companies just installed one gigawatt of projects in [just the 3rd] quarter [of 2021].”

This means, says Spector, that “more batteries [are] charging up in moments when the grid has more power than is necessary and discharging during the hours when electricity is scarce and more valuable.” This is a critical point. PV and wind often produce more energy when the sun is shining or the wind is blowing than is needed to meet demand. Storage allows energy providers to harvest solar and wind energy whenever it is generated and deliver it after the sun sets or to minimize demand charges during other times of peak usage. The need for storage will continue to expand as fossil-fuel generation is phased out and more and more PV and wind resources are added to grids.

Unfortunately, most current investment focuses on lithium-ion batteries, which are ubiquitous and getting cheaper, but still only economical for storage durations of four hours or less. Other longer-duration technologies like flow batteries are only slowly gaining traction, or like gravity or compressed air, still experimental. If you’d like to know more about 247Solar’s unique solution to long-duration storage — up to 20 hours — using proven technologies, please let us know.

Mine Power – Opportunities in Inclusive Mining

A new report from the Alliance for Rural Electrification (ARE) and UNIDO ITPO Germany highlights significant opportunities for mining companies that operate near off-grid or grid-underserved communities to leverage their investments in renewable energy. The report’s foreword makes the case:

“The global mining sector is currently facing a conundrum. As a growing energy and emission-intensive industry, the mining sector continues to be exposed to policy and regulatory risks arising from concerns of climate change and impacts on the environment.” At the same time, “decentralised renewable energy (DRE) offers a variety of benefits, such as a reliable and modern electricity supply, cost reduction, reduced environmental impacts, as well as the potential to mitigate climate change at scale.”

Inclusive mining – the concept of sharing DRE systems with surrounding communities, will help ensure a sustainable mining practices while increasing electricity access to underserved regions. It will also enable miners to avail themselves of funding opportunities for their DRE projects and realize ESG benefits they would otherwise miss. Read the full report here, and check out the case study it includes of a 247Solar inclusive mining project under discussion in Australia. Download the full ARE-UNIDO report here.
