Science and Technology:

¶ “Why Slowing Down Ships Could Help Save The Planet” • Shipping is one of the world’s dirtiest industries. Emissions from ships account for 3% of global emissions. But a study shows that putting speed limits on ships could have broad environmental benefits. Cutting ship speeds by 20% could reduce CO₂ emissions from ships by 24%. [CNN]

¶ “NASA’s All-Electric X-57 Experimental Plane Debut With Interview” • Empirical Systems Aerospace delivered the first configuration of the X-57 to NASA. It has two 60-kw electric motors and high-performance batteries. The early model will allow NASA to start testing. In its final configuration, the plane will have 14 electric motors and propellers.

¶ “Solar farm helps balance UK grid – at night” • Lightsource BP said that a trial using one of its solar plants in East Sussex had successfully provided night-time reactive power voltage support services to the electricity network – a first for a solar asset in the UK. An “inexpensive tweak” to inverters can send the grid power back at a slightly different voltage. [RenewEconomy]

¶ “Researchers Say Nanomaterials Are Key To Energy Storage” • According to Drexel University, a main focus of battery research is finding ways to store more electrons. Using “nanostructuring,” researchers introduce particles, tubes, flakes, and stacks of nanoscale materials into storage systems components, allowing more electrons to be stored. [CleanTechnica]


¶ “‘Bleak’ Outlook As Carbon Emissions Gap Grows” • Countries will have to increase their carbon-cutting ambitions five-fold if the world is to avoid warming by more than 1.5°C, the UN says. The annual emissions gap report shows that even if all current promises are met, the world will warm by more than double that amount by 2100. [BBC]

¶ “ScotlandPower Plans Major Onshore Wind Initiative” • In 2015, then UK prime minister David Cameron blocked any government support for onshore wind farms, and construction fell 80%. Now, as political parties are supporting windpower, Scottish Power has begun planning for a major expansion of onshore wind projects. [CleanTechnica]

¶ “ACWA Connects Saudi’s First Utility Scale Renewables Plant To The Grid” • ACWA Power announced that Saudi Arabia’s first renewable energy project, the Sakaka solar plant, was connected successfully to the national grid. Full commercial operation of the 300-MW project is to be achieved before the end of the year 2019. [Power Engineering International]

¶ “WindEurope Plots 450-GW EU Offshore Goal” • To achieve the European Commission’s target of 450 GW of offshore wind by 2050 requires annual installation rates to rise from 3 GW today to over 20 GW in 2030, a report from WindEurope says. The study suggests that the bulk, 212 GW, should be deployed in the North Sea. [reNEWS]

¶ “Siemens Gamesa Unveils 11-MW Offshore Turbine” • Siemens Gamesa unveiled an offshore wind turbine that can reach top power of 11 MW. The German-Spanish manufacturer said the “DD Flex” machine relies on “constant digital observations” to drive the power to 11 MW. It showed the machine at WindEurope Offshore 2019 in Copenhagen.

¶ “Most Consumers Want Companies To Target 100% Renewable Energy” • A poll commissioned by Greenpeace Australia Pacific shows that the corporate shift to renewable energy is driven not only by economics, but also public expectation. Nearly three out of four Australian consumers expect companies to target 100% renewable energy. [One Step Off The Grid]

¶ “Solar And Battery Microgrid Achieves 90% Renewables For WA Gas Hub” • Horizon Power’s poster child for the shift to a distributed renewable grid, the Western Australia Pilbara town of Onslow, says its solar and battery microgrid is already helping to deliver “more reliable” and cleaner power, at levels of up to 90% renewables.

¶ “Echoing Japanese Bishops, Pope Backs Abolition Of Nuclear Power” • Speaking to survivors of Japan’s 2011 “triple disaster,” when the country was hit by a devastating mega-earthquake, a tsunami, and an incident at a nuclear plant, Pope Francis called for the abolition of nuclear facilities, echoing the voice of the local bishops. [Angelus News]


¶ “Ohio Denies AEP Cost Recovery For 400 MW Of Proposed Solar, But Projects Expected To Proceed” • The Public Utilities Commission of Ohio denied American Electric Power’s request to charge customers for development of two solar projects, totaling 400 MW. It said the utility had not shown a need for the additional generation. [Utility Dive]

¶ “Putting New York City’s Waterfront At The Heart Of A Renewable Energy Revolution” • Today, the East Coast looks to a pipeline of offshore wind energy projects, or ocean-based wind farms, that could generate more than 20 GW of power within 10 years. Offshore wind energy could power up to a million homes in New York within five years. [Next City]

¶ “80% Of US Accepts That There’s A Human Role In Climate Change” • Recent events, including fires, unusual temperatures, and destructive storms, may have increased public acceptance of climate change. A Pew Research Center poll says about 80% of the public accepts the evidence that human activities contribute to the changing climate. [Ars Technica]
