By Frédéric Simon – While fossil gas is often seen as a transition fuel towards a fully decarbonized energy mix, GE Gas Power sees low-carbon gas as “a destination technology” with the potential to convert power plants to run 100% on clean hydrogen by 2030.
“Today, we have a 50% hydrogen capability for combustion in our largest baseload gas turbines” used for power generation, said Martin O’Neill, vice president at GE Gas Power.
The company’s objective, he explained, is to continue research and development in order “to advance the percentage of hydrogen combustion capability towards 100% by 2030,” he told a EURACTIV event earlier this month.
However, getting there would require a rapid scale up in the production of clean hydrogen, he added. And that will only be possible if multiple sources of low-carbon hydrogen are added to the mix, including so-called “blue hydrogen” where emissions are somehow captured and stored. more>

What is ZR+?
You may be familiar with 400ZR, but thanks to continued innovation in coherent optical technology, network operators can also look forward to a new generation of longer-reach, multi-rate pluggable coherent solutions – “ZR+”. The generic term ZR+ means different things to different people, so learn about the wide range of different solutions it encompasses, the industry standards and MSAs driving their development, and additional coherent pluggable capabilities addressing even higher performance.
By Patricia Bower – Global optical networks continue to evolve, necessitating new and innovative solutions to meet the requirements of network operators to maximize fiber utilization and reduce the cost of data transport. Coherent optical transmission has been the key technology supporting both requirements over the last decade— and this will continue for the next stages of network evolution.
In early 2020, 800G-capable performance-optimized transport systems were introduced and have since been deployed around the world allowing customers to benefit from new network efficiencies and cost savings from this latest generation of coherent technology. What’s next?
In 2021, coherent pluggables supporting data rates from 100G to 400G and optimized for low power and small space requirements for high-density modular systems will start to be deployed in networks. This latest generation of products extend the economic benefits of coherent innovation into new application areas.
400ZR is an example of one of the first 400G solutions in this new class of pluggable coherent products to hit the market and will initially be used by hyperscale data center operators for single-span connectivity between data centers. Implemented predominantly in QSFP-DD form factors, 400ZR will serve the specific requirement for large-scale switch fabric extension by plugging directly into router faceplates for massive parallel data center interconnect of 400GbE for distances of 80 – 120km. more>

Why investors shouldn’t dismiss recent upside surprises in U.S. inflation as a temporary phenomenon and how they can recalibrate their strategy.
By Lisa Shalett – Investors who braced for a sharp rise in April’s U.S. inflation readings from last year’s muted levels early in the pandemic were still surprised by the 4.2% year-over-year surge in the consumer price index (CPI)—double the highest projection in a Bloomberg survey of economists, even after hints in March of a coming uptick.
The CPI data released last week weren’t the only concerning indicators of inflation’s resurgence. The producer price index, which tracks wholesale and manufacturing costs, increased by 6.2% year-over-year in April—the highest reading since the U.S. Bureau of Labor Statistics started tracking the data in 2010—after rising 4.2% year-over-year in March. Perhaps most concerning, these moves came with strong gains in the “core” readings, which strip out volatile commodity-related drivers, such as food and energy prices.
While many, including the Federal Reserve, see the jump in prices as “transitory,” we believe it’s much more than just a blip. To be sure, some short-term inflation drivers, such as supply-chain bottlenecks, are likely to subside. However, we believe this post-pandemic business cycle has ushered in a new period of sustained higher fiscal spending, higher inflation and rising long-term interest rates. In particular, we see five secular shifts that could contribute to this dynamic, each of which can be summed up using terms that begin with the letter D:
- Deglobalization: In the past decade, globally optimized supply chains helped to check price inflation. Now, the COVID-19 pandemic has likely sped up a shift toward deglobalization that could return supply chains to the U.S., which could contribute to consumer price inflation.
- Deficits: Federal debt and deficits are exploding in the wake of unprecedented amounts of stimulus meant to counter pandemic disruptions. With the Fed essentially buying new government debt, dramatic growth in the money supply could be inflationary.
- Dollar debasement: More stimulus to keep long- and short-term rates low would likely drive inflation through further declines in the value of the dollar against other major currencies.

How to forge relationships with the ‘enemy’
By Alice G. Walton – When it comes to seemingly insurmountable conflicts, the one between Israelis and Palestinians ranks high.
But a Maine summer camp program called Seeds of Peace, which brings together Jewish Israeli and Palestinian teens, has been overwhelmingly successful at facilitating not just tolerance but close, positive relationships, suggests research by Facebook’s Shannon White and University of California at Berkeley’s Juliana Schroeder (both graduates of Chicago Booth’s PhD Program), along with Booth’s Jane L. Risen.
The work grew out of previous research by Schroeder and Risen, who in 2014 studied the program and found that campers’ attitudes toward people of the other nationality (in the “outgroup”) became significantly less negative after completing the program, particularly for campers who said they’d formed a close relationship with someone from the outgroup.
Why was that the case? To find out, White, Schroeder, and Risen analyzed data from surveys they collected of more than 500 participants who attended one of the Seeds of Peace summer camps between 2011 and 2017. Schroeder and Risen surveyed the teens before their camp stay began, including how positive, sympathetic, and anxious they felt toward or about members of the other group. more>
