Renewable Energy Makes Things Tough On The Grid, But New Software Could Help
By Bruce Watson – In 2016, more than two-thirds of power in Europe came from nonrenewable sources. Globally, renewables are expected to reach parity with coal and gas around 2040.
Nevertheless, the speed with which intermittent renewables — the sun doesn’t always shine and the wind doesn’t always blow — are coming on board is making it harder for European utilities to balance the grid. That’s because the grid, as large as it is, is also a delicate system where supply must match demand at all times or there’s a risk of blackouts.
In France, for example, strong winds in the north mixed with a sunny week on the Riviera in the south can lead to a surfeit of electricity that puts the balance at risk.
The intermittency also makes profits hard to find, with European utilities on average struggling to increase profits 1 percent in 2016. Countries around the world are watching how Europe uses thermal generation to keep the grid balanced; prioritizes low-cost, clean and renewable energy; and keeps utilities profitable amid a rapidly changing energy network. more> https://goo.gl/iC532f

The Time To Invent The Technologies That Will Power Our Future Is Now
By David Danielson – The year 2050 sounds pretty far away, doesn’t it? But in terms of the world our children and grandchildren will inherit, 2050 is today: it’s right around the corner.
By 2050, there will be almost 10 billion people on Earth, one-third more than there are today, with essentially all of this population growth predicted to be in currently less-wealthy nations around the world. And the approximately 9 billion people living in these nations in 2050 will be hungry to consume more energy, requiring an almost doubling of energy usage per person to achieve a good standard of living by some estimates.
At the same time, the world’s best scientists have determined that we must simultaneously reduce our global greenhouse gas emissions by 80 percent or more by 2050, relative to today’s levels, in order to avoid the most devastating impacts of climate change.
Scaling and improving today’s clean energy technologies can take us part of the way to the future we all want. Technologies like wind power, solar power, LEDs, electric vehicle batteries, and many others are already rapidly approaching widespread cost-competitiveness with traditional forms of energy.
But these technologies alone will not be enough: it has become clear now that to provide universal energy access around the world while simultaneously achieving required emissions reductions, we must unleash an unprecedented Energy Innovation Revolution today – and over the next few years – to develop the transformative new energy technologies that will be needed to close the gap between the 2050 we are headed for and the 2050 we want. more> https://goo.gl/57jCZr

By Yari M. Bovalino & Tomas Kellner – Frank Herzog was still in elementary school in the historic Bavarian city of Bamberg when he fell in love — with metals. So ardent was his passion that he later quit high school to pursue it. “I was young when I realized that I loved the material,” he says.
More than three decades later, Herzog’s fascination with shiny objects continues. He is the founder and CEO of Concept Laser, a pioneering maker of 3D printing machines, including the world’s largest industrial printer for metals. His machines can print delicate jewelry and dental implants as well as massive engine blocks for trucks.
Last fall, GE acquired a majority stake in Herzog’s company, and Concept Laser is now part of GE Additive, a new GE business dedicated to supplying 3D printers, materials and engineering consulting services.
Herzog, 45, grew up in a state that’s obsessed with engineering. Mechanical engineers alone account for 17 percent of Bavaria’s workforce. more> https://goo.gl/uS55hn
Leaner Than Lean: How Digitalization Transforms Manufacturing
By Randy Stearns – If you want to see the future of manufacturing, follow the Tama River about 45 kilometers upstream from Tokyo’s Haneda Airport to the GE Healthcare facility in Hino, Japan. Inside this outwardly conventional, low-rise suburban business complex is emerging the blueprint for the future of manufacturing, tweak by painstaking tweak.
The Hino factory makes both parts for large medical scanners and small, precision equipment. Compared with similar facilities, its production lines are exceptionally efficient — fast, with less waste, errors and unplanned downtime — thanks in part to the successful integration of advanced digital information technology with operational systems. GE calls this convergence of hardware and software on the shop floor the brilliant factory.
The Hino plant is where the Industrial Internet meets Kaizen, the Japanese concept of continuous improvement pioneered by Toyota after World War II that undergirds Lean methods for eliminating waste in manufacturing. more> https://goo.gl/euCTYE

The Power Of Data: How Software Is Helping Keep Iceland’s Lights On
By Julie Khoo – There are many reasons to visit Iceland. This former Viking stronghold is now the most peaceful country and home to the happiest and most literate people in the world — one in 10 Icelanders on average reportedly has published a book.
A nation of glaciers, volcanoes and waterfalls, Iceland is also, at least metaphorically, one of the greenest places, generating all of its electricity from renewable sources such as hydropower and geothermal energy.
The grid receives electricity from generators that move at a constant frequency, just like the merry-go-round. When a power-hungry load suddenly disconnects from a high-inertia grid with lots of generators, the grid frequency will barely change.
But when a generator or load goes offline in a low-inertia grid like the one in Iceland, Landsnet has to act quickly to return the frequency to its normal level.
This can be a real headache. If the frequency drops or climbs too quickly, it can knock down parts of the grid and cause power failures. It can even cause a geothermal power station to automatically disconnect from the grid to protect the equipment from large stresses. Dramatic changes in frequency can also create “electrical islands” as different areas on the grid react to the changes. This can lead to blackouts. more> https://goo.gl/LyyN60

Physicists Are ‘Breeding’ SchröDinger’s Cat, And It Could Reveal The Limits of The Quantum World
By Bec Crew – Physicists have figured out how to ‘breed’ Schrödinger’s cat – an object in a quantum superposition of two states with opposite properties – to produce enlarged versions that could one day reveal the limits of the quantum world.
If they can continue to breed their ‘cats’ even bigger, the experiment could finally reveal the exact point at which objects switch between classical and quantum physics – the divide between the microscopic and macroscopic worlds that physicists have been chasing for decades.
The original Schrödinger’s cat thought experiment states that if you put a live cat in an explosion-proof box with a bomb, until you open the box, you’ll have no idea if the bomb exploded and the cat died. Or maybe the bomb didn’t explode and the cat is still alive.
From our perspective, as long as the box is shut, the cat is occupying two realities. It’s both dead and alive, because we can’t confirm which one, but we know it can’t be neither.
This isn’t just a hypothetical question – in quantum physics, being in two different states at the same time is known as a superposition state, and it’s the entire basis of quantum computing, which is set to revolutionise how we process data in the future. more> https://goo.gl/XMFMB6
Competing for the World
By Jeffrey R. Immelt – Today, I want to give you some views on globalization … what works, and what doesn’t work, and what needs to change. Please keep foremost in your mind that the U.S. has 5 percent of the world’s population with 25 percent of the GDP. I hope to persuade you that – rather than pulling back – the U.S. can win the global game. But, we have to compete.
I have spent my career doing just that. When I joined GE – in 1982 – 80 percent of our revenue was in the U.S. In 2017, nearly 70 percent of our revenue will be global. We have customers in 180 countries and our exports exceed $20 billion. Our U.S. workers earn high wages because they make leadership products that we sell around the world. Globalization has made us become more efficient, more competitive.
Today, people question globalization. The U.S. is challenging trade deals and has effectively shut down its export bank. The U.S. is not alone. Protectionist barriers are rising in Europe and Asia as well. Economic nationalism is replacing free trade as the dominant idea of the era. Meanwhile, the Chinese are replacing the U.S. as the trade leader on the global stage, growing their influence through expanding relationships and economic development.
How did an ideal so connected to American influence and success become so demonized? In retrospect, there were key changes along the way. I’ll name a few. more> https://goo.gl/WLgK88

Dam Powerful: These Engineers Are Connecting Hydropower To The Internet
By Tomas Kellner – There are many large waterways in North America. Then there’s the Saint Lawrence River, whose lumbering current links the Great Lakes to the Atlantic Ocean.
Montreal, Quebec’s business capital with 1.7 million inhabitants, fits on an island sliced off from the mainland by the waterway and its tributaries. Just west of the city, the river’s surface is so wide it could pass for a sea.
This abundance of water is a clue to why Quebec has become one of the world’s leaders in carbon-free energy. Lakes and rivers here pack enough power to supply the 7 million Quebecois with 95 percent of the electricity they need.
“This country and this region really know how to run hydropower well,” says Anne McEntee, vice president for renewable energy services at GE Renewable Energy. “But there’s no reason why you cannot get even better. For decades, advances in hydro have primarily been on the physical side of things, being able to get more out of your physical assets through redesign and engineering. We are now looking at digital applications as the next advance.”
“Our new software allows us to observe how the physical components behave in real time.”
McEntee says the insights allow customers to adapt the turbine’s operations to the specific conditions on-site, rather than strictly follow the manual. “We can take into account the real water and flow conditions versus what it was designed to do,” she says. “This allows us to make use of the error tolerance and get more power when we need it, like when the price is favorable. We are constantly looking for opportunities to squeeze out 1, 2, 3 percent of efficiency.” more> https://goo.gl/PTA8xd
