Beautiful Coal and Other Maladies

President Trump hasn’t been able to bring back “beautiful, clean coal” as he promised four years ago. As mines and power plants continue to close, the question many are asking in the diminishing American coal industry is—what now?

The use of coal to generate electricity in the U.S. is expected to fall more than a third during Mr. Trump’s first term, data from the U.S. Energy Information Administration show, as a glut of cheap natural gas unlocked due to fracking and increasingly competitive wind and solar sources gained market share. More than half of that drop happened before the new coronavirus outbreak. That compares with a decline of about 35% in coal consumed for power generation during Mr. Obama’s eight years in office.

In 2019, the U.S. consumed more renewable energy than coal for the first time since the 1880s, federal data show…“Coal isn’t coming back. You can’t legislate it,” said Karla Kimrey , previously a vice president at Wyoming-based coal producer Cloud Peak Energy Inc., which filed for bankruptcy protection last year. Domestic demand has continued to drop as utilities retire coal power plants and turn to cheap natural gas and renewables to make electricity, trends that have only accelerated as economies have slowed due to the pandemic. With less demand for power, many utilities have cut back on coal generation first, as it is generally more expensive

Meanwhile the rise of “ESG” or environmental, social and governance investing is constricting the industry’s ability to obtain capital, current and former executives say.  As major investors such as JPMorgan Chase & Co. and BlackRock Inc., the world’s largest asset manager, turn away from coal over concerns about climate change, coal companies are struggling to secure the insurance they need to operate. That hurts not only companies that mine the thermal coal used to generate electricity, but also those that mine metallurgical coal to make steel.

The End of the Mindless Self-Indulgence: the Gulf States

Algeria needs the price of Brent crude, an international benchmark for oil, to rise to $157 dollars a barrel. Oman needs it to hit $87. No Arab oil producer, save tiny Qatar, can balance its books at the current price, around $40 (summer 2020)….The world’s economies are moving away from fossil fuels. Oversupply and the increasing competitiveness of cleaner energy sources mean that oil may stay cheap for the foreseeable future. 

Arab leaders knew that sky-high oil prices would not last for ever. Four years ago Muhammad bin Salman, the de facto ruler of Saudi Arabia, produced a plan called “Vision 2030” that aimed to wean his economy off oil. Many of his neighbours have their own versions. But “2030 has become 2020…” 

Still, some see an upside to the upheaval in oil-producing states. The countries of the Gulf produce the world’s cheapest oil, so they stand to gain market share if prices remain low. As expats flee, locals could take their jobs…

Remittances from energy-rich states are a lifeline for the entire region. More than 2.5m Egyptians, equal to almost 3% of that country’s population, work in Arab countries that export a lot of oil. Numbers are larger still for other countries: 5% from Lebanon and Jordan, 9% from the Palestinian territories. The money they send back makes up a sizeable chunk of the economies of their homelands. As oil revenue falls, so too will remittances. There will be fewer jobs for foreigners and smaller pay packets for those who do find work. This will upend the social contract in states that have relied on emigration to soak up jobless citizens….With fewer opportunities in the oil-producing states, many graduates may no longer emigrate. But their home countries cannot provide a good life. Doctors in Egypt earn as little as 3,000 pounds ($185) a month, a fraction of what they make in Saudi Arabia or Kuwait. A glut of unemployed graduates is a recipe for social unrest…

For four decades America has followed the “Carter Doctrine”, which held that it would use military force to maintain the free flow of oil through the Persian Gulf. Under President Donald Trump, though, the doctrine has started to fray. When Iranian-made cruise missiles and drones slammed into Saudi oil facilities in September 2019, America barely blinked. The Patriot missile-defence batteries it deployed to the kingdom weeks later have already been withdrawn. Outside the Gulf Mr Trump has been even less engaged, all but ignoring the chaos in Libya, where Russia, Turkey and the UAE (to name but a few) are vying for control.

A Middle East less central to the world’s energy supplies will be a Middle East less important to America. ..As Arab states become poorer, the nature of their relationship with China may change. This is already happening in Iran, where American sanctions have choked off oil revenue. Officials are discussing a long-term investment deal that could see Chinese firms develop everything from ports to telecoms… Falling oil revenue could force this model on Arab states—and perhaps complicate what remains of their relations with America.

Praying for Renewable Energy

In the wake of the Fukushima nuclear disaster in 2011, Fukushima prefecture itself pledged to get all its power from renewable sources by 2040.  The hoped-for transformation, however, has been “slow and almost invisible.”…Renewable generation has grown from 10% of the power supply in 2010 to 17% in 2018, almost half of which comes from old hydropower schemes. Most nuclear plants, which provided more than a quarter of the country’s power before the 2011 disaster, have been shut down… But for the most part they have been replaced not by wind turbines and solar panels but by power stations that burn coal and natural gas. The current government wants nuclear plants to provide at least 20% of electricity by 2030. It also wants coal’s share of generation to grow, and has approved plans to build 22 new coal-fired plants over the next five years. The target for renewables, by contrast, is 22-24%, below the current global average, and far lower than in many European countries.

Geography and geology provide part of the answer. Japan is densely populated and mountainous. That makes solar and onshore wind farms costlier to build than in places with lots of flat, empty land. The sea floor drops away more steeply off Japan’s coasts than it does in places where offshore wind has boomed, such as the North Sea. And although geothermal power holds promise, the most suitable sites tend to be in national parks or near privately owned hot springs.

Government policies also help stifle the growth of renewable energy. Since the end of the second world war, privately owned, vertically integrated regional utilities have dominated the electricity market. These ten behemoths provide stable power within their regions, but do little to co-ordinate supply and demand across their borders…The limited transmission between regions makes it even harder than usual to cope with intermittent generation from wind turbines and solar panels. It also reduces competition, which suits the incumbent utilities just fine…Recent reforms have attempted to promote renewables both directly and indirectly…The “feed-in tariff”, obliging utilities to pay a generous fixed price for certain forms of renewable energy—a policy that has prompted investors to pile into solar and wind in other countries. In 2016, the government fully liberalised the retail electricity market. It has also set up new regulatory bodies to promote transmission between regions and to police energy markets. In April 2020 a law came into force that requires utilities to run their generation, transmission and distribution units as separate businesses. These reforms constitute a policy of “radical incrementalism”.

Critics say the steps have been too incremental and not radical enough. Utilities continue to make it time-consuming and costly for new entrants to get access to the grid, imposing rules that are “not fair for newcomers”, according to Takahashi Hiroshi of Tsuru University. Existing power plants are favoured over new facilities, and the share of renewables is limited, on the ground that their intermittency threatens the grid’s stability.

But even if the government is timid, investors can still make a difference…. Several of Japan’s big multinationals have pledged to switch to clean power on a scale and schedule that put the government’s targets to shame. Environmental activism has made banks and businesses wary of investments in coal. Even big utilities have come to see business opportunities in renewables, especially in the government’s imminent auction of sites for offshore wind plants. Two of them, Tohoku Electric Power and Tokyo Electric Power (TEPCO), have announced plans this year to issue “green bonds” to finance renewables projects. In March 2020, TEPCO established a joint venture with Orsted, a Danish oil firm that has become a pioneer in offshore wind.

The Big Trash Burners: Does it Make Sense to Incinerate Waste?

Global waste is expected to hit 3.4 billion tons by 2050 from 2.01 billion tons in 2016, according to the World Bank. As recycling programs encounter challenges and landfills in the U.S. and Europe reach capacity or face regulations making them more expensive, incinerators are becoming the most viable option for many municipalities to deal with much of their garbage. England now burns more municipal waste than it recycles or landfills. China—already the world’s biggest trash burner—is building more incinerators. And incineration companies say, for the first time in years, expansion projects are on the table in the U.S., although the industry faces significant legal and community challenges. Overall, incinerator-plant capacity is forecast to rise 43% globally between 2018 and 2028, according to Ecoprog, a consulting firm…..

Another growth driver is a European Union target for member states to cap the amount of municipal trash they send to landfill at 10% by 2030. Local communities and environmental groups have launched strong opposition to expansion of incineration plans, citing environmental and public-health concerns. Incinerator plants are also called waste-to-energy plants since the heat from burning trash is used to generate electricity, and many governments classify that electricity as renewable energy, a characterization opponents dispute…..But advocates for clean energy…say that while some energy is recovered by burning, recycling or composting garbage would save far greater amounts of energy.

Critics also say cities that own their incinerator plants have little incentive to pursue waste-reduction efforts because the plants are designed to run at full capacity. “Many countries are over-investing in incineration to cut down on landfilling, which will eventually lock them into burning,” said Janek Vähk, development and policy coordinator for Zero Waste Europe.

Can Nuclear Power Beat Climate Change?

The 2019 World Nuclear Industry Status Report (WNISR2019) assesses the status and trends of the international nuclear industry and analyzes the potential role of nuclear power as an option to combat climate change. Eight interdisciplinary experts from six countries, including four university professors and the Rocky Mountain Institute’s co-founder and chairman emeritus, have contributed to the report.

While the number of operating reactors has increased over the past year by four to 417 as of mid-2019, it remains significantly below historic peak of 438 in 2002.  Nuclear construction has been shrinking over the past five years with 46 units underway as of mid-2019, compared to 68 reactors in 2013 and 234 in 1979. The number of annual construction starts have fallen from 15 in the pre-Fukushima year (2010) to five in 2018 and, so far, one in 2019. The historic peak was in 1976 with 44 construction starts, more than the total in the past seven years.

WNISR project coordinator and publisher Mycle Schneider stated: “There can be no doubt: the renewal rate of nuclear power plants is too slow to guarantee the survival of the technology. The world is experiencing an undeclared ‘organic’ nuclear phaseout.”  Consequently, as of mid-2019, for the first time the average age of the world nuclear reactor fleet exceeds 30 years.

However, renewables continue to outpace nuclear power in virtually all categories. A record 165 gigawatts (GW) of renewables were added to the world’s power grids in 2018; the nuclear operating capacity increased by 9 GW. Globally, wind power output grew by 29% in 2018, solar by 13%, nuclear by 2.4%. Compared to a decade ago, nonhydro renewables generated over 1,900 TWh more power, exceeding coal and natural gas, while nuclear produced less.

What does all this mean for the potential role of nuclear power to combat climate change? WNISR2019 provides a new focus chapter on the question. Diana Ürge-Vorsatz, Professor at the Central European University and Vice-Chair of the Intergovernmental Panel on Climate Change (IPCC) Working Group III, notes in her Foreword to WNISR2019 that several IPCC scenarios that reach the 1.5°C temperature target rely heavily on nuclear power and that “these scenarios raise the question whether the nuclear industry will actually be able to deliver the magnitude of new power that is required in these scenarios in a cost-effective and timely manner.”

Over the past decade, levelized cost estimates for utility-scale solar dropped by 88%, wind by 69%, while nuclear increased by 23%. New solar plants can compete with existing coal fired plants in India, wind turbines alone generate more electricity than nuclear reactors in India and China. But new nuclear plants are also much slower to build than all other options, e.g. the nine reactors started up in 2018 took an average of 10.9 years to be completed. In other words, nuclear power is an option that is more expensive and slower to implement than alternatives and therefore is not effective in the effort to battle the climate emergency, rather it is counterproductive, as the funds are then not available for more effective options.

Eco-Peace for the Middle East?

EcoPeace, a joint Israeli, Jordanian and Palestinian NGO thinks it just might. In December it presented an ambitious, if far from fully developed, $30 billion plan to build a number of desalination plants on the Mediterranean shore of Israel and the Gaza Strip. At the same time, large areas in Jordan’s eastern desert would host a 200 square km (75 square mile) solar-energy plant, which would provide power for desalination (and for Jordan) in exchange for water from the coast. “A new peaceful economy can be built in our region around water and energy” says Gidon Bromberg, EcoPeace’s Israeli director. Jordan and the Palestinian Authority are already entitled to 120 million cubic meters of water a year from the Jordan river and West Bank aquifers but this is not enough to meet demand, particularly in Jordan, which regularly suffers from shortages….

The main drawback to making fresh water from the sea is that it takes lots of energy. Around 25% of Jordan’s electricity and 10% of Israel’s goes on treating and transporting water. Using power from the sun could fill a sizeable gap, and make Palestinians less dependent on Israeli power. Renewables supply just 2% of Israel’s electricity needs, but the government is committed to increasing that share to 17% by 2030. Jordan, which has long relied on oil supplies from Arab benefactors, is striving for 10% by 2020.,,, Over the past 40 years there has been a series of plans to build a Red Sea-Dead Sea canal that would have irrigated the Jordan Valley and generated power, none of which have been built.

Beyond many logistical and financial obstacles, the plan’s boosters also have to navigate a political minefield.

Nuclear Power – Sweden

Sweden may be facing the phase out of nuclear power following agreement by the country’s Social Democrats and their junior coalition partner, the Green Party, to set up an energy commission tasked with achieving a 100% renewable electricity system….The parties said in separate, but identical statements that nuclear power should be replaced with renewable energy and energy efficiency. The goal, they said, should be at least 30 TWh of electricity from renewable energy sources by 2020. A goal for 2030 has yet to be set, they added. Support for offshore wind and solar power are needed “in addition”, they said.

Nuclear power “should bear a greater share of its economic cost”, they said. “Safety requirements should be strengthened and the nuclear waste fee increased.”  Waste management in Sweden is undertaken by SKB while safety regulations are set by the Swedish Radiation Safety Authority. Both of these operate independently of government.  State-owned utility Vattenfall’s plan to build a new nuclear power plant has been “interrupted”and the company will lead the country’s energy system towards a higher share for renewable energy, they said.

Floating Power Plants: Cayman Islands

A United States company OTEC International is in talks with Caribbean Utilities Company (CUC), Grand Cayman’s electrical provider, to supply renewable energy to the island via Ocean Thermal Energy from a platform at North Side.  According to the company:

“The Cayman Islands has documented its storm history with precision, which made it easier for OTEC International to identify locations where  Floating Power Platforms (FPPs) can be securely sited and appropriately designed to survive strong storm conditions.  The first phase of the Cayman project would be the generation of 6.25-MW renewable electricity* from an FPP that would be permanently moored less than a mile from shore. At this distance from shore, the plant’s visual impact will be minimal because of the platform’s overall low profile. The power generated would be transported to a substation onshore via cable and connected to the island’s CUC grid…..A comprehensive Environmental Impact Assessment (EIA) will be completed before the project can receive all necessary licenses and permits from various governmental authorities.”

*This type of ocean-thermal electricity plant takes advantage of the temperature difference between warm surface water and cold deep seawater.

The Power of Batteries and Micro-Grids

Who needs the power grid when you can generate and store your own electricity cheaply and reliably? Such a world is drawing nearer: good news for consumers, but a potential shock for utility companies. That is the conclusion of a report this week by Morgan Stanley, an investment bank, which predicts that ever-cheaper solar and other renewable-energy sources, combined with better and more plentiful batteries, will allow many businesses and other electricity users to cut the cord on their electricity providers.

Tesla Motors, an American maker of electric cars, recently said it will build a “gigafactory”, which by 2020 will turn out as many lithium-ion batteries as the whole world produced last year (2013). These batteries can do more than power cars; they can also store electricity which is produced when it is not needed, and discharge it when it is….

In poor, volt-starved countries, a lorry-mounted aircraft engine can become a mobile gas-fired power station. GE recently installed 24 such units in Algeria, providing 30MW of power. Local difficulties meant it took six months; that was fast by the standards of big power stations, “but we could have done it in ten days,” says Lorraine Bolsinger, who heads GE’s new distributed-generation business….

Morgan Stanley reckons that if Tesla’s factory provides the cheap batteries it promises, Californian households will be able to run off a solar-plus-storage system costing just $350 a year. Buying electricity off the grid may cost them around $750 a year by then.

Morningstar, an investment-research firm, says that though distributed generation represents only 1% of America’s installed capacity now (compared with 20% in Germany), it could make up a third by 2017 and could “kill” utilities in their current form. Small-scale producers will dump their surplus power on the market at prices below those at which the utilities can recoup their cost of capital—and thus pay to maintain the grid.

America’s Electric Power Research Institute last month produced a paper highlighting the dangers of an unplanned move to distributed generation, using Germany as an example. The dash for renewables there has strained the power network and made life hard for utilities. This week one of the country’s largest, RWE, announced that it made a net loss of €2.8 billion ($3.8 billion) in 2013, its first annual loss in more than 60 years, as the rising supply of electricity from (subsidised) renewable sources undercut its prices.
