Laboratories around the world are racing to make printable perovskite solar cells, produced in abundance and so thin they can be wrapped around almost anything. It’s a huge advantage over the typical silicon cell that is relatively big and fragile. And perovskite is much less expensive to produce. David Beynon at Swansea University describes research there that has demonstrated how a roll of plastic film can be loaded into a printing press to … [Read more...]
U.S. EPA: new rules proposed for cutting Fossil Fuel-Fired Power Plant emissions
In May the U.S. Environmental Protection Agency proposed new rules regulating carbon emissions from fossil fuel-fired power plants. Here, four experts from the Center for Strategic and International Studies – Cy McGeady, John Larsen, Kyle Danish and Mathias Zacarias – make their assessment and point at the wide-ranging implications. The main issues covered include CCS, hydrogen-fuelled generation, state clean energy standards, carbon pricing, … [Read more...]
Financing Renewable Hydrogen globally: ramp up to 2030 only needs $150bn/year
Dolf Gielen, Priyank Lathwal and Silvia Carolina Lopez Rocha at the World Bank present a thorough review of the pathway to financing global clean renewable hydrogen over the coming decades. The wind and solar that powers production will continue to get cheaper, and so will electrolyser costs as they scale up. Nevertheless, the total financing will still be considerable. World Bank analysis shows around $30tn between now and 2050 will be needed … [Read more...]
Five charts on the Energy Transition: the 2020s is the decade of maximum disruption. By 2030 the endgame will be clear
Sam Butler-Sloss and Kingsmill Bond at RMI present a succinct summary of why the energy transition matters, how the 2020s is the era of maximum disruption, and how by 2030 the transition’s endgame will be apparent (though far from complete). Four key technologies are already entering the exponential growth stage: solar, wind, EVs and heat pumps. As early as 2030 their cheapness will flush away the fossil equivalents in succeeding decades, say the … [Read more...]
4 CEOs explain their innovations: EV charging, aviation fuel, hydrogen fuel cells, nuclear waste-to-energy
To meet our global climate targets, new solutions, technologies and pathways will be needed. Existing technologies, on their own, can’t be scaled up fast enough to do it. Robin Pomeroy and Kate Whiting at the World Economic Forum pick out highlights from their podcast that hears from four CEOs of innovative companies, covering EV charging, aviation, hydrogen fuel cells, and new nuclear. Today’s millions of EV charging points needs to rise to 450m … [Read more...]
Geothermal Heat Pumps: can new U.S. “IRA” support make it go mainstream?
Biden’s Inflation Reduction Act in the U.S. is meant to drive forward the best clean energy solutions. To help make sure geothermal heat pumps play their fullest role, RMI has done a study of its benefits as well as published guides on how developers can take advantage of the various new laws and support mechanisms. Lauren Reeg, Mike Henchen, Chris Potter and Chris Stone at RMI start with a summary of the technology and its applications, before … [Read more...]
Germany closes its last 3 nuclear reactors. Understanding the reasons why
Germany has a long history of being resistant to all things nuclear. No new commercial reactors have been built since 1989. By 2023, nuclear made up only 6% of its power mix. To meet its decarbonisation goals, the government is confident of its target to reach an 80% renewables share in electricity demand by 2030 without nuclear. Hence the shut-down of its last three reactors over the weekend. Yet nuclear supporters say that leaving the last six … [Read more...]
Renewables “cost of capital” in Europe lower than oil, gas, coal. What the U.S. and China can learn
The ultimate price of anything is highly dependent on the cost of capital needed to put it in place. That cost reflects the risks financial markets perceive. And policy certainty reduces risk. Gireesh Shrimali, Christian Wilson and Xiaoyan Zhou at Oxford University, writing for WEF, summarise their global study which shows the cost of capital for different energy technologies, and therefore which ones will trend upwards and dominate. They cover … [Read more...]
Russia–Ukraine war: household energy costs worldwide have nearly doubled, with the poorest hit hardest
A new study measures the effect of the Russia-Ukraine war on household energy costs worldwide. It’s nearly doubled, explain Klaus Hubacek, Jin Yan and Yuru Guan at the University of Groningen and Yuli Shan at the University of Birmingham. Their study sums the costs of direct energy like heating, cooling, lighting and mobility, as well as the indirect costs through the energy used to produce goods and services. That doubling translates into an … [Read more...]
Steel decarbonisation: Australia must stop making excuses and follow Europe’s lead
Australian steel makers, major global exporters, must stop making excuses about decarbonisation and look to Europe for a role model, argues Simon Nicholas at IEEFA. A pattern of behaviour by Australia’s steel makers reveals that their excuse is that low-carbon solutions are not yet ready, leaving only promises of carbon capture (as yet unproven at scale) some time in the future. Nicholas notes that these promises will never have to be kept by the … [Read more...]
Can new cheap, frequent “laser” monitoring of critical components extend Nuclear plant lifetimes by decades?
For nuclear to thrive, rather than retreat and be displaced by alternatives, plants reaching the end of their lifetimes need to be replaced with new ones. Or, perhaps more interestingly, can the existing plants have their lifetimes greatly extended, safely and cheaply? David Chandler at MIT describes new research led by MIT to detect and measure defects in critical components to ensure that damage from heat and radiation has not led, and will not … [Read more...]
Utah: 140MW Geothermal bid can beat the cost and performance of the proposed Nuclear SMR
The U.S. state of Utah is processing an agreement for a new Small Modular Reactor (SMR) to provide baseline and dispatchable power. The SMR bid quotes a price of $89/MWh. But cost overruns will tie the state’s consumers to whatever high prices entail, says Dennis Wamsted at IEEFA. Now a geothermal bid from NV Energy has been presented that offers the same capacity at around $70/MWh. Wamsted explains why the 140MW geothermal project would meet … [Read more...]
How to sell Heat Pumps to the public in Europe
In EU households, 62.8% of energy consumption is for space heating, and another 15.1% for water heating, mostly powered by fossil fuels. Heating and cooling is responsible for 52% of final energy demand in Europe. So, with REPowerEU, the EU has once again strengthened support for heat pumps to achieve energy independence and climate goals. Heat pump sales in Europe grew by an unprecedented 34% in 2021, thanks to a total 2.18m heat pump units … [Read more...]
Doubling clean energy investments from “natural” redirection of existing spend on infrastructure, buildings, fossils +more
Annual investments in clean energy stand at $1.4tn, now greater than investments in fossil fuels ($1tn). But that needs to double by 2030. This steep climb will be made easier by the natural cycle of global investment, as well as the cost-benefits of abandoning fossil fuels for renewables and greater efficiencies, says Stephen Peake at The Open University. Each year, around a quarter of our GDP is anyway spent on new machinery, buildings and … [Read more...]
Small Modular Reactor cost overruns: the same old problems haunt new nuclear in Utah
Much hope is being placed on Small Modular Reactors (SMR) making new nuclear plants competitive. But David Schlissel at IEEFA summarises their research into the publications, updates and statements coming from the stakeholders involved with the SMR by UAMPS (Utah Associated Municipal Power Systems) and NuScale Power Corporation that shows that costs are going out of control, a persistent problem in the nuclear industry. The original target power … [Read more...]
