Grace Hopper

Two female tech pioneers won the Presidential Medal of Freedom. Grace Hopper, known as the “first lady of software,” and Margaret Hamilton, regarded for her leadership role in a NASA software team that helped land a man on the moon, continued to break the glass ceilings in computer science upon receiving this prestigious award.

Hopper was one of the first programmers of the Harvard Mark I and a pioneer in computer science until she passed away in 1992.

When discussing Hopper’s achievements, U.S. President Barack Obama said, “If Wright is flight, and Edison is light, then Hopper is code.”

Hamilton played a major role on the 1960s NASA team that got a man to the moon. She was critical in developing the on-board flight software for the Apollo space program.

President Obama said, “Luckily for us, Margaret never stopped pioneering. She symbolizes that generation of unsung women who helped send humankind into space.”

From cellphones to cyber command, the work of these women has helped shape the world we currently live in.

According to scientists at the University at Buffalo, a new glowing dye called BODIPY could be a central part of the liquid-based batteries that researchers are looking at to power our cars and homes.

BODIPY – or boron-dipyrromethene – is a fluorescent material that researchers believe could be an ideal material for stockpiling energy.

While the dye is fluorescent, that’s not what initially attracted scientists. According to new research, the dye has chemical properties that enables it to store electrons and participate in electron transfer. These two properties are critical for energy storage.

The new research shows that BODIPY-based batteries operate efficiently and display promising potential for longevity, functioning for more than 100 charge cycles.

“As the world becomes more reliant on alternative energy sources, one of the huge questions we have is, ‘How do we store energy?’ What happens when the sun goes down at night, or when the wind stops?” says lead researcher Timothy Cook, ECS member and assistant professor of chemistry at the University at Buffalo. “All these energy sources are intermittent, so we need batteries that can store enough energy to power the average house.”

InSeNewly developed semiconductor materials are showing promising potential for the future of super-fast electronics.

A new study out of the University of Manchester details a new material called Indium Selenide (InSe). Like graphene, InSe if just a few atoms thick, but it differs from the “wonder material” in a few critical ways. While graphene has been hailed for its electronic properties, researchers state that it does not have an energy gap – making graphene behave more like a metal than a semiconductor.

Similarly, InSe can be nearly as thin as graphene while exhibiting electronic properties higher than that of silicon. Most importantly, InSe has a large energy gap, which could open the door to super-fast, next-gen electronic devices.

2016 is set to be the world’s hottest year on record. According to the World Meteorological Organization’s preliminary statement on the global climate for 2016, global temperatures for January to September were 0.88°C above the long-term (1961-90) average, 0.11°C above the record set last year, and about 1.2°C above pre-industrial levels.

While the year is not yet over, the final weeks of 2016 would need to be the coldest of the 21st century for 2016’s final number to drop below last year’s.

Record-setting temperatures in 2016 came as no real surprise. Global temperatures continue to rise at a rate of 0.10-0.15°C per decade, and over the five years from 2011 to 2015 they averaged 0.59°C above the 1961-1990 average.

Giving temperatures a further boost this year was the very strong El Niño event of 2015−16. As we saw in 1998, global temperatures in years where the year starts with a strong El Niño are typically 0.1-0.2°C warmer than the years either side of them, and 2016 is following the same script.

Almost everywhere was warm

Warmth covered almost the entire world in 2016, but was most significant in high latitudes of the Northern Hemisphere. Some parts of the Russian Arctic have been a remarkable 6-7°C above average for the year, while Alaska is having its warmest year on record by more than a degree.

Almost the whole Northern Hemisphere north of the tropics has been at least 1°C above average. North America and Asia are both having their warmest year on record, with Africa, Europe and Oceania close to record levels. The only significant land areas which are having a cooler-than-normal year are northern and central Argentina, and parts of southern Western Australia.

What’s Next for Batteries

BatteryTwenty-sixteen marked the 25th anniversary of the commercialization of the lithium-ion battery. Since Sony’s move to commercialize the technology in 1991, the clunky electronics that were made possible by the development of the transistor have become sleek, portable devices that play an integral role in our daily lives – thanks in large part to the Li-ion battery.

“There would be no electronic portable device revolution without the lithium-ion battery,” Robert Kostecki, past chair of ECS’s Battery Division and staff scientist at Lawrence Berkeley National Laboratory, tells ECS.

Impact of Li-ion technology

Without Li-ion batteries, we wouldn’t have smartphones, tablets, or laptops – more so, electric vehicles would have a slim chance of competing in the transportation sector and dreams of large-scale energy storage for a renewable grid may be dashed. Without the Li-ion, there would be no Tesla. There would be no Apple. The landscape of Silicon Valley as we know it today would be vastly different.

While the battery may have hit the marketplace in the early ‘90s, pioneers such as Stanley Whittingham, Michael Thackeray, John Goodenough, and others began pushing the technology in the ‘70s and ‘80s.

In its initial years, Li-ion battery technology boomed. As the field gained more interest from researchers after commercialization, developments started pouring in that doubled, or in some cases, tripled the amount of energy the battery was able to store. While progress continued over the years, the pace began to slow. Incremental advances at the fundamental level opened new paths for small, portable electronics, but have not answered demands for large-scale grid storage or an electric vehicle battery that will allow for a drive range of over 300 miles on a single charge.

Carbon dioxideFor the third year in a row, global carbon dioxide emissions from fossil fuels and industry have barely grown, while the global economy has continued to grow strongly. This level of decoupling of carbon emissions from global economic growth is unprecedented.

Global CO₂ emissions from the combustion of fossil fuels and industry (including cement production) were 36.3 billion tonnes in 2015, the same as in 2014, and are projected to rise by only 0.2% in 2016 to reach 36.4 billion tonnes. This is a remarkable departure from emissions growth rates of 2.3% for the previous decade, and more than 3% during the 2000s.

Given this good news, we have an extraordinary opportunity to extend the changes that have driven the slowdown and spark the great decline in emissions needed to stabilise the world’s climate.

This result is part of the annual carbon assessment released today by the Global Carbon Project, a global consortium of scientists and think tanks under the umbrella of Future Earth and sponsored by institutions from around the world.

The world relies on battery power. The smartphone market alone – which is powered by lithium-ion batteries – is expected to reach 1.5B units in 2016. ECS member Steve Martin believes he may be able to take those batteries to the next level through efforts in glassy solids.

Martin, a professor at Iowa State University and associate of the U.S. Department of Energy’s Ames Laboratory, has been in the field of battery research for over 30 years. Throughout that time, his main focus of research has shifted to measuring the basic properties of glassy solids and trying to understand how their ions move and the thermal and chemical stability.

Martin believes that using glass solids as the electrolytes in batteries would make them safer and more powerful. This is an effort to diverge from traditional liquid-electrolyte batteries, which have experienced issues with safety and energy capacity.

To push this research, Martin recently received a three-year, $2.5M grant from the DOE.

“This is my dream-come-true project,” Martin says. “This is what I’ve been working on for 36 years.”

Wind TurbinesRenewable energy efforts around the world have grown exponentially over the past few years. Countries such as Japan have developed the world’s largest floating solar project, initiatives like Solar Hope are working to provide clean energy to sub-Saharan Africa, and Hawaii is leading the charge in the U.S. with its commitment to 100 percent clean energy by 2045. Now, the Netherlands has marked a new milestone in renewables by implementing a total of 2,200 wind turbines.

According to Dutch News, the turbines in the Netherlands produce enough energy to power 2.4 million households.

However, the 3,379 megawatts of power produced by the turbines is only a third of what the Netherlands needs to meet the European Unions’ energy 2023 energy targets. But Gijs van Kuik, head of the Wind Energy Institute at Delft University, believes that the Netherlands is still on track to meet these goals due to recent developments in offshore wind farms.

OilPresident…Donald…Trump. For those on both sides of the aisle who vowed “Never Trump!,” that’s going to take some getting used to. On this morning after a stunning election, the first impulse may be to describe the future in apocalyptic phrases. Game over for the climate! Game over for NATO! Game over for the Clean Power Plan! Game over for Planned Parenthood!

While there are certainly extreme outcomes possible for these and many other issues that divide our nation, we may see some moderation, especially on matters where the divisions do not rigidly follow ideological fault lines.

Of course, the president-elect himself is famous neither for hewing to right wing orthodoxy nor for consistency between his various pronouncements. As he has said: “I like to be unpredictable.”

But make no mistake, in the energy and climate space Trump’s number one priority is to dismantle the Obama legacy as he sees it. And he sees it largely through the lens of organizations like the U.S. Chamber of Commerce and the American Petroleum Institute, pro-fossil fuel organizations severely allergic to regulations.

A prime target is the Environmental Protection Agency and its regulation of greenhouse gases via the Clean Power Plan and methane emissions measures, which are described as “job killers.”

Fossil fuel revolution

The Clean Power Plan, which sets limits on carbon emissions from power plants, has been stayed by the courts for the moment, but one should not forget that EPA’s responsibility to regulate CO2 emissions under the Clean Air Act was affirmed by the Supreme Court. This sets up a potential conflict among the executive, legislative and judicial branches.

President Trump and a Republican-controlled Congress may hollow out and handcuff the EPA, but EPA’s responsibility to regulate greenhouse gases will remain unless existing law is modified by Congress or by a Court returned to full strength with Trump appointees.
