Tools to design energy systems resilient to natural disasters: from small villages to big cities

November 9, 2022 by Connor O'Neil and Moriah Petty

There is little doubt that emissions reduction will not be enough to cope with climate change. Adaptation will be essential too. Connor O’Neil and Moriah Petty at NREL describe how the National Renewable Energy Laboratory is developing free-to-use tools to help configure and create energy systems that are resilient to natural disasters. The tools have already been applied to small and large populations, ranging from a 500-person town to big … [Read more...]

Compact voltage converters for integrating new DERs into the grid

October 20, 2021 by NREL

The switches and converters needed to plug new clean energy technologies into the grid are going to be needed soon. The cheaper and smaller they are, the easier it will be to cope with the wide range of solutions coming down the pipe. NREL and its partners are building a megawatt-scale prototype converter that could fit the bill. They will be 1/5th the size and 1/10th the weight of existing alternatives: small enough to place almost anywhere. … [Read more...]

Tipping Points reached for Solar, Wind, Batteries, EVs. What of the other Clean Energy techs?

June 5, 2020 by Ji Chen and Koben Calhoun

History shows a disruptive technology’s tipping point can be under 5% of market share, that’s all it takes. The number of horses in use peaked in the U.S. once car ownership reached 3%. Gas lighting in the UK peaked with electric lighting at just 2% of the market. Landline phones in the U.S. fell precipitously after mobiles captured 5% of the market. Ji Chen and Koben Calhoun at RMI argue the tipping point has already been passed for solar, wind, … [Read more...]

Multi-energy “island” Microgrids can increase grid resilience

March 11, 2020 by Xi Zhang

As the number of different technologies producing power and providing storage increases, the grid is getting complicated. The best way to make it resilient against outages is therefore changing. The traditional way is to shut down the failing plant, leaving the rest of the grid to cope as best as it can with the change in voltage and frequency. Xi Zhang at the Energy Futures Lab, Imperial College, describes the research looking at multi-energy … [Read more...]

Onsite solar and storage powers off-grid telecom towers

March 19, 2019 by Dr Thomas Hillig

There are more than 3m telecom towers globally, and powering them is a $100bn market. It's a particularly important growth sector in developing countries. They are already using mobiles to leapfrog the laying of costly landlines, but because they lack grids that stretch to remote communities they need to power towers that are off the grid. Dr Thomas Hillig says as solar and storage costs continue to drop they are replacing diesel gensets as the … [Read more...]

Cyberattacks: the military considers micro grids as the answer

March 1, 2019 by Lukas TrakimaviÄŤius

European power grids have long been considered as potential targets for major cyberattacks given the enormous damage they could inflict. Successful cyberattacks against power grids could not only cause societal and economic disruptions, but also put a dent in the military readiness of European countries. In the event of a blackout, the lights could go out in town halls and military facilities alike. Lukas TrakimaviÄŤius explains how micro grids … [Read more...]

Energy as a service: light, heat, mobility, information

February 15, 2019 by Walt Patterson

https://static-hoffmanncentre.chathamhouse.org/thumbnails/blocks/images/2019-01-07-LED-Lightbulb.jpg.1010x568_q85_crop_upscale.jpg

Large scale electricity generators, unconcerned with end-use, want to sell you more electricity, argues Walt Patterson of the Hoffmann Centre for Sustainable Resource Economy, based at Chatham House. But the arrival of small-scale, localised and micro-grid suppliers could see the electricity generation business turned on its head. It opens the door to the selling of the service – light, heat, refrigeration, motive power, information – rather than … [Read more...]
