The U.S. Department of Energy’s Energy Information Administration (EIA) has released its influential 2022 “Annual Energy Outlook” (AEO2022) which projects the electricity mix over the next 30 years. (The modelling takes policies and global conditions as they were in November 2021, so the current Russia-Ukraine crisis is not accounted for, nor any future unforeseeable shocks, and assumes no new policies to 2050). Sandra Sattler at the Union of … [Read more...]
“Floato-voltaics”: floating solar farms on existing municipal water reservoirs
The municipality of Cohoes, population 17,000, in New York State, is building a floating solar farm on its 10-acre water reservoir. It should power all the city-owned buildings and streetlights, save $500,000/year in electricity costs and still leave 40% of the generated electricity remaining for other civic use. It will cost $6m. It will be a first for a U.S. city, explains Connor O'Neil at NREL. The case for city “floato-voltaics” is so … [Read more...]
Russia-Ukraine: Support for U.S. Oil & Gas producers must tie them to low-emissions investments
Like many countries, the U.S. is set to raise oil and gas production to compensate for cuts in Russian imports consequent to the war in Ukraine. The danger is that short-term solutions to sky rocketing fossil fuel prices will take precedence over climate targets. But Ben Cahill at CSIS explains how this is an opportunity for the Biden administration to give support to fossil energy producers with one hand and extract solid commitments on … [Read more...]
Using electrostatic repulsion to clean Solar panels, avoiding up to 30% power loss
Dust build-up on solar panels can reduce the power output by as much as 30% in just one month. Even a 1% reduction in power for a 150MW solar installation could result in a $200,000 (€180,000) loss in annual revenue. Cleaning normally requires purified water, but that needs to be trucked in to prime locations like deserts where solar potential is highest. Cleaning with brushes is labour intensive and can damage surfaces irreparably. David … [Read more...]
Reducing Europe’s dependence on Russian Oil and Gas: immediate, short and long term strategy
Atlantic Council Global Energy Center experts and associates offer their template for drastically reducing Europe’s dependence on Russian oil and gas. It’s broken down into immediate, short (one to three years) and long term (beyond three years) actions. It’s wide-ranging and comprehensive. Some actions are already in play, including maximising gas storage, ready for next winter. Some are the ramping up of existing plans (clean energy, … [Read more...]
What’s your average lifetime CO2 footprint by year of birth, to achieve net-zero by 2050?
To reach net zero by 2050, babies born today must have CO2 footprints ten times smaller over their lifetimes than their parents and grandparents. In rich countries it’ll be fifteen times, while in emerging economies like India and China it’ll be around four times smaller. Laura Cozzi, Olivia Chen and Hyeji Kim at the IEA summarise how they have calculated the average allowable lifetime CO2 footprint by year of birth. Taking the two extremes, the … [Read more...]
Lifting and lowering tons of bricks: the best storage solution for Wind and Solar intermittency?
It’s a high capacity storage system that’s simplicity itself. Use excess wind and solar to raise heavy weights. Keep them at a height for as long as you like. Lower them to generate electricity. James Conca looks at a system being developed by Energy Vault and already being demonstrated in the Swiss national grid. At scale, a single “vault” with 10,000 bricks will have an annual output of 27 GWh, sitting on only 14 acres of land. The bricks are … [Read more...]
Our Hydrogen future: 27 authors imagine the world in 2030-2050
Here’s something very different for our readers today, and an opportunity for you to register for our Webinar and Q&A on Wednesday Feb 16th at 09:00 CET (register here). It’s to mark the book launch of “Touching Hydrogen Future”, where 27 energy experts from around the world have written a chapter each. They are fictional accounts of what our world could like in the near future. The countries covered are the Netherlands (2029), Denmark … [Read more...]
Carbon Taxes have a multiplier effect on clean energy policies
President Biden’s Build Back Better package has already had to be cut back drastically. The climate part of the package is to halve the U.S.’s greenhouse gas pollution from its peak by 2030. Given the limitations on what Biden can do, will tax credits alone (favouring low-carbon solutions) achieve the target, asks Meredith Fowlie at the Energy Institute at Haas. She reviews papers that say it almost certainly won’t. However, the addition of a … [Read more...]
Grid-scale modelling of Distributed Energy Resources and dynamic pricing for all customers
Smart grids can solve multiple problems now and throughout the lifetime of the energy transition. The supply from hundreds (existing + new wind, solar, etc.) and ultimately millions (rooftop solar, EV batteries) of power sources can be matched in real time with demand from all major customer devices (air conditioners, water heaters, batteries, EVs). Dynamic pricing keeps the peaks low and the troughs high. It takes the pressure off total load, … [Read more...]
The Green Hydrogen disruption: what nations, firms and investors are doing to reshape global energy
Everyone knows the new hydrogen economy has huge up front capital costs to make the green H2 (called GH2), the logistical challenges of delivering it where it’s needed, and creating the customer base to consume it. But Tim Buckley at IEEFA believes the policy support is already shaping up to make GH2 a successful disruptor of the global energy system. He runs through the nations, companies and investors at the beginning of the learning curve that … [Read more...]
Where can Europe get its Gas if Russia cuts off supplies?
What impact will the confrontation between Russia and NATO over Ukraine have on Europe’s energy security? Russia provides nearly half of Europe’s natural gas, and Moscow could tighten the flow if hostilities break out. If that happens, where would Europe get its gas from? Amy Jaffe at Tufts University looks at the constraints on global LNG supply (mainly liquification and regasification capacity), the global ability to redirect shipments to … [Read more...]
New York City to stop new buildings connecting to the Gas network
New York City is the U.S.’s largest metropolis, over twice the size of second spot Los Angeles, and is still growing. It has just passed a bill that effectively stops new buildings from hooking up to the gas network. The significance is not simply because of NYC’s global prominence, but because it gets very cold in winter with average temperatures just above freezing point. The move is a major win for the electrification of buildings. The … [Read more...]
U.S. shale production is rising. But by how much more, and how fast?
The dramatic increase in gas and electricity prices worldwide has raised concerns about energy security. It why U.S. shale production is rising. But by how much more, and how fast? Ben Cahill at CSIS looks at lessons learned over the last ten years by the sector to understand the drivers. Previously, shale firms grew so fast that many investors lost a lot of money. Then, the 2020 oil shock imposed discipline and firms preserved cash, but that … [Read more...]
The Gas Crunch: EU and China can share lessons on Energy Security and Renewables Integration
With adversity comes opportunity. The global gas crunch has hurt countries around the world but has also made them appreciate their common concerns. That has provoked policy-makers to take a serious look at current and future energy security policies. In the EU the competitive gas markets, enabled by short-term spot markets, has reminded us of the value of long-term contracts when prices are volatile and rising. Meanwhile, China’s … [Read more...]
