News and Opinion

Coverage of distributed energy since July 30, 2020.

Microgrids should be the future of electricity. Let's fund them.

"...It is fertile ground for the new technologies of distributed generation, energy management and energy storage. Relatively short product-development cycles, the commodification of services, the “internet-of-energy,” sophisticated data analytics and mass production of distributed energy resources all challenge status quo business models and regulatory frameworks. Activities and technologies “beyond the meter” and out of reach of the traditional utility modus operandi are proliferating..."


Ontario doubles down on gas-fired electricity generation, admits emissions will rise

"...The IESO expects electricity generated from natural gas will be replaced over time by new emissions-free generation, storage, and demand and transmission solutions. However, not everybody agrees this is the right move. What people are reading Hurricane Danielle set to slam Alberta with Category 5 shitstorm By Max Fawcett | Opinion | October 7th 2022 In a Sept..."


How Distributed Energy Resources Can Lower Power Bills, Raise Revenue in US Communities

"...When it comes to distributed energy resources, the future is here, with more solar arrays on rooftops, more electric vehicles on the streets, and more so-called controllable assets like water heaters inside buildings. The reason for the growing popularity of these resources, DERs for short, is no mystery: They can reduce utility bills for residents and businesses, help communities meet climate and equity goals and make the electric grid more resilient..."


ABB and Hydrogen Optimized expand hydrogen partnership, including a strategic investment

"...The companies will leverage their respective capabilities and resources to rapidly commercialize HOI's patented RuggedCell™ high-power water electrolysis technology for the world's largest green hydrogen plants. Water electrolysis is the process of applying electrical energy to split water into hydrogen and oxygen. RuggedCell™ technology converts renewable electricity such as hydro, solar and wind power into green hydrogen for industry..."


Sandia developing micro-grids to power future Moon base

"...Other problems include developing systems and software to regulate electricity at the processing plant so the voltage levels remain even as demand shifts across time scales ranging from milliseconds to entire seasons. To do this, Sandia has developed a Scalable Microgrid facility and control-system-design methodology to study the Moon base's energy requirements and specifications. The idea is to produce a top-down design, where the control system is developed first along with the energy storage specifications, then the components to meet those specifications are developed..."


Councillor proposes adding solar panels to three city of Ottawa buildings

"...The councillor also wants the city to establish one position and funding in the 2023 budget to implement a "distributed energy resource framework. "..."


ZipCharge reveals EV charging hubs packing suitcase-sized powerbanks

"...Each Go is home to a 4, 6 or 8-kWh battery, and once the powerbank has given its all, the driver will receive a notification via the app and the unit can be unplugged and returned to the hub for recharging before being made available to the next customer. ZipCharge has announced a simple pricing structure where each 4-kWh top-up will cost a dollar, with no additional connection fees applied. Obviously a single Go powerbank won't be enough to juice up an EV's battery completely, but the company reckons it could add up to 20 miles (32 km) of range – which might just be enough to get drivers home in a pinch..."


Five future-friendly ways sustainable design can help the planet in 2022 Corporate Knights

"...Against a backdrop of horrific climate disasters, a number of developments in 2021 offered some cause for optimism, from the International Energy Agency’s call to reach net-zero emissions by 2050 to new commitments from global banks and institutional investment funds to decarbonize their holdings. A growing number of cities, including New York, are enacting rules that ban gas hook-ups for new buildings. Meanwhile, in a case that could have long-term implications for energy-inefficient design in the era of climate change, a group of San Francisco condo owners sued a developer for US$10 million because the west- and south-facing units in their all-glass curtain-wall tower overheated so severely..."


LETTER: Summerland solar project will create greenhouse gases

"...Coun. Richard Barkwill raises objections to solar energy project Feb. 13, 2021 3:30 p..."


Russian chemists proposed a new design of flow batteries

"...Due to this setup, redox flow batteries, unlike many other energy storage devices, enable independent scaling of power and capacity of the battery, which are determined by the size of MEA and electrolyte volume, respectively. In addition, redox flow batteries exhibit minimal self-discharge over extended periods and their electrolytes do not degrade even after tens of thousands of operating cycles, making them promising candidates for storing large amounts of energy in the smart power grids. For example, they can store excess electricity generated by photovoltaic solar cells during daylight and generate back-up electricity at night or in cloudy weather..."
