Grid modernisation is going to be very expensive. What’s the best way to pay for it? The financial incentives governments put in place now will determine what investments get made, how cost-effectively it’s done, and who ultimately pays. Meredith Fowlie at UC Berkeley’s Energy Institute at Haas explains that a common method is for a government to give some sort of guaranteed return on investment for the new asset. But it’s far from ideal. … [Read more...]
U.S. DoE: National Roadmap for Grid-Interactive Energy-Efficient Buildings
Buildings account for more than 70% of U.S. electricity use and one-third of economy-wide CO2 emissions. Andrew Satchwell at the Lawrence Berkeley National Laboratory presents the U.S. Department of Energy’s comprehensive plan, “A National Roadmap for Grid-Interactive Efficient Buildings”, that could deliver up to $200bn in savings to the U.S. power system and cut CO2 emissions by 80m tons per year by 2030 (6% of total power sector emissions). … [Read more...]
Germany: will the end of feed-in tariffs mean the end of citizens-as-energy-producers
Germany’s feed-in tariffs ran for 20 years. The guaranteed electricity price and connection to the grid incentivised ordinary citizens and communities to invest in smaller scale solar, biomass and wind generation for their homes and local areas. But that guaranteed price is now too expensive, and so the tariffs are ending and lowest-bid auctions are taking over. It’s the bigger players who are winning those auctions, and some of the existing … [Read more...]
Case study Italy: Optimising emissions cuts means we’ll need “grey” and “blue” Hydrogen too
Europe is committing to hydrogen. The ideal is “green” hydrogen, produced from renewable energy alone. Carlo Stagnaro at Istituto Bruno Leoni analyses emissions and costs in Italy to make the case for policy-makers to consider including “grey” and “blue” hydrogen in their strategies too. Because grids are far from green today, a new wind and solar plant will reduce more emissions by feeding the grid than by making hydrogen. “Grey” hydrogen, … [Read more...]
How Clean Energy Standards have driven clean electrification in the U.S.
John Rogers at the Union of Concerned Scientists presents evidence from the U.S. of the effectiveness of using standards to drive clean electrification. In principle it’s simple: set a legal requirement for the percentage of clean electricity. How it’s done depends on the efforts of all the actors affected. 30 states are using different versions of Clean Energy Standards (CES) – the first began in 1983 and more than half of them began before 2004 … [Read more...]
Fit for 55: Does squeeze on gas make coal exit harder? Event summary + video
On May 18, 2021, Energy Post hosted an expert panel with the European Commission, E3G, CERRE and PKEE (the Polish Electricity Association, who also sponsored the discussion). It looked at some of the key EU support mechanisms offered to countries/companies transitioning away from coal, including the EU ETS' Modernisation Fund, the Just Transition Fund  and also how State Aid Guidelines (EEAG) contribute. We asked Stefaan Vergote (Senior Advisor … [Read more...]
What is making Denmark a decarbonisation success? Policy, society, geography
Denmark is proving itself to be a decarbonisation leader, happy to turn its back on its history of oil and gas production and heavy reliance on coal. Its ambitious goal of cutting GHG emissions by 70% by 2030 makes it a global policy frontrunner, second only to Finland which aims to be climate neutral by 2035. Thibault Menu references his report for IFRI that asks what makes Denmark special. It has a long tradition of  providing stability and … [Read more...]
Why expensive Buildings Renovations? By the time they’re done the grid will be emissions-free
The big budgets being talked about for the transition require us to decide how much to spend, and on what. Maximilian Auffhammer at the Energy Institute at Haas explains why he thinks a lot of the money being earmarked for buildings renovations would be better spent elsewhere. By the time the renovation wave has successfully “reached the shoreline” in the next few decades buildings will be powered overwhelmingly by clean grids (that’s the plan, … [Read more...]
Micro-nuclear reactors: up to 20MW, portable, safer
Scientists are working on micro-nuclear reactors that are so small they can fit on the back of a truck or a standard 40-foot shipping container, explains Christina Nunez writing for the Argonne National Laboratory. Deliberately small, generating up to 20MW, they could provide zero-carbon power in remote settings or supplement electrical power grid recovery. Another idea would be to locate them on remote highways for re-charging long distance … [Read more...]
Coal exit: EU policy revisions must face both tech and socioeconomic obstacles
By 2030, the EU must cut its emissions by at least 55% compared to 1990 levels. Agreeing on the target was hard enough. Much harder will be agreeing on the design of the rules, regulations and financial support needed to achieve it. Pieter de Pous at E3G scopes out the major decline already experienced by coal - the worst emitting energy source - before looking at the challenges faced by heavy coal users in Central and Eastern Europe (CEE). The … [Read more...]
Covid-19: want to vaccinate 75% of the world? Developing nations need small-scale Solar refrigeration first
The flexibility of small scale solar can help roll out vaccines to remote and poorer parts of the world that the grid doesn’t reach. Access to power for refrigeration is vital when you consider that most vaccines must be stored between 2°C and 8°C, like for measles and polio. It’s the same for the Covid-19 vaccines from Johnson & Johnson and AstraZeneca-Oxford. But the Moderna vaccine must be stored at between -25°C and -15°C. The … [Read more...]
Public opposition and grid integration costs: the two limiting factors for Wind?
Are we heading for an over-reliance on wind? With wind generation costs continuing to drop dramatically, Schalk Cloete takes a data-driven look at the obstacles wind will face as its contribution to the global energy mix (a little over 2% today) keeps rising. In the main, it is grid integration and public opposition to very visible turbines – and they are related. Putting turbines out of sight and offshore will increase transmission costs. And … [Read more...]
California: Designing electricity rates that are fair and encourage EV and Heat Pump take-up
Electricity prices in California are not fair and not good for incentivising electrification, says James Sallee at the Energy Institute at Haas, because of the way people are being billed. There is no doubt that electrification (grid upgrades, etc.) and climate mitigation (including controlling California’s wildfires caused by power cable failures) must add to the cost of transition. But Californians can now find themselves paying up to twice the … [Read more...]
Case studies: Strategic EV funding starts with an Essential Charging Network
Building a nationwide EV charging network is a daunting prospect. Camille Kadoch and Julia Hildermeier at RAP look at those places that are being strategic about it, starting with an essential network that will allay the concerns of consumers on the verge of buying an EV but put off by worries that they will get stuck somewhere with a flat battery. That’s frustrating, given the average American drives only 37 miles a day and Europeans 32 … [Read more...]
Improving grid response to support climate targets and increased renewables [Energy Post event video]
We present our video of the online discussion from February 24, 2021 on smartgrid response. Digital, automated, data-driven smart response systems can play a key role in grid security and stability going forward. This makes asset monitoring and controllability - underpinned by the Smart Grid Indicator which is now part of the EU Electricity Directive (Article 59) - a vital link in the chain. Taking part were Vera Silva, COT, General Electric and … [Read more...]
