The IEA has raised its 2027 forecasts for total renewables additions in its main scenario to 2,383GW – around the total power capacity of China. That’s a 28% increase on the previous estimate and up 76% from two years ago, explains Josh Gabbatiss at Carbon Brief who summarises the IEA’s latest forecasts. Globally, solar power will overtake gas by installed capacity in 2026 and coal in 2027. There are two main drivers for this acceleration. High … [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...]
Can the Czech Republic revive its clean energy ambitions?
Although an early enthusiast for solar in 2009 the Czech Republic’s clean energy ambitions stalled. The share of green electricity was only 12% last year, with solar contributing 3% and wind just 1%. The current government is now reviving the nation’s drive towards carbon-free energy. Will new Czech policies along with EU initiatives like REPowerEU, the Green Deal and the Modernisation Fund successfully breathe new life into the Czech transition? … [Read more...]
Global Wind Speeds: are they falling due to climate change?
Last year, Europe experienced a “wind drought”, with wind speeds falling 15% in many regions, sometimes more. Deeper research shows speeds dropped gradually between 1978 and 2010, though rose again in the last decade. It’s difficult for the science to create a clear picture and predict long term trends. But the IPCC forecasts slowing winds for the coming decades, saying average annual wind speeds could drop by up to 10% by 2100. Jim Robbins at … [Read more...]
Europe’s decoupling of electricity and gas prices: the crisis is temporary, so why do it?
The debate is intensifying over how to decouple power prices from the extraordinarily high natural gas prices in Europe. Simona Benedettini and Carlo Stagnaro warn that the current problem of high prices is not caused by the mis-functioning of electricity markets, but by the exceptional trend in gas prices. So should the markets be re-designed at all? Will we lose the benefits of the current design, one being the reliable profits that renewables … [Read more...]
Reactor shutdowns in Nuclear-dependent France expose the need for a diversified mix of Renewables
Events are showing that a nation’s heavy reliance on a single source of energy is unwise. It’s not just gas. The heatwave is causing problems for France’s nuclear fleet, where the use of water for cooling has had to be restricted. All compounded by routine and unexpected maintenance shutdowns. As nuclear typically delivers well over 60% of its power, and also made it Europe’s biggest power exporter (until now), France is feeling the consequences. … [Read more...]
Record global clean energy spending, but it’s still not enough and costs are rising
Since 2020, clean energy investment has grown by 12% per year – it was only 2%/year during the five years after the 2015 Paris Agreement. That boost is the main reason why total global energy investment is set to reach $2.4tn in 2022, according to the latest “World Energy Investment” report from the IEA. It’s very good news that spending on solar PV, batteries and EVs is now growing at rates consistent with reaching global net zero emissions by … [Read more...]
How the U.S. can meet its target of halving emissions by 2030
Writing for Carbon Brief, John Bistline at the Electric Power Research Institute summarises his co-authored paper “Actions for reducing US emissions at least 50% by 2030”, the target set by the Biden administration. The paper provides detailed projections and actionable insights about the policies and technology deployment needed to achieve this near-term climate goal. Roughly 70-90% of emissions reductions by 2030 must come from the power and … [Read more...]
Reversible Hydrogen fuel cells: can H2 gas-to-power support the grid economically?
We know about making green hydrogen from excess intermittent wind and solar. We also know that that same intermittency means the gaps in wind and solar generation need filling. Green hydrogen is very expensive to make. But what if that green hydrogen could be economically converted back to power when needed? Writing for Stanford University, Edmund Andrews describes new research, in collaboration with the University of Mannheim in Germany, into … [Read more...]
Renewable Ammonia’s role in reducing dependence on Gas
Today, IRENA and the Ammonia Energy Association (AEA) released its “Innovation Outlook Renewable Ammonia” which updates in detail the current state and prospects for green ammonia as an energy carrier. Here, Dolf Gielen, Francisco Boshell and Gabriel Castellanos at IRENA and Kevin Rouwenhorst and Trevor Brown at the AEA summarise the findings. Worldwide ammonia production, though fossil-based, is already at-scale as a feedstock for fertiliser. So … [Read more...]
Gas crunch causes electricity crisis despite record cheap clean energy. Time to create a “green energy pool”?
In the UK and similar nations, the gas crisis is ballooning electricity prices too. That’s because the UK operates a wholesale electricity market where the most expensive power sets the price. As we enter an era where renewables are getting cheaper every year, it’s time to change that model so that consumers see the benefits, argues Michael Grubb at UCL. The design of electricity systems is not keeping up with the revolution in renewable energy. … [Read more...]
Synchronous condensers will stabilize the power grid as the Faroe Islands pivot to 100% green energy
The isolated Faroe Islands in the North Atlantic has an ambitious goal to become the world’s greenest group of islands. That means by 2030, SEV, the islands’ power utility, will be using 100% green electricity from hydropower, solar and wind and potentially tidal streams. As well as being an important climate change initiative, this will bring economic benefits as the Faroes will no longer rely on expensive fossil-fuel imports. However, … [Read more...]
Replacing centralised power with Distributed Energy Systems needs new policies and coordination
We need integrated resilient smart grids that can accommodate the rapid growth of intermittent renewables as well as the rise of “prosumers” who both buy and sell electricity into the grid. This is the focus of three online discussion sessions on February 8th, 9th and 10th organised and hosted by power management company Eaton. The proliferation of multiple generation sources (solar, wind, batteries and other clean, flexible technologies) means … [Read more...]
What do German households pay for power? Costs, surcharges, taxes, grid fees
Power prices in Germany are among the highest in Europe. Though the high costs are in large part due to the mandatory support for renewable energy sources, most customers continue to support the country's energy transition. That might be because German households only pay a little over 9% of their average monthly income on energy, similar to France and the Netherlands. In contrast, Bulgarian households spend more than 25% percent on electricity, … [Read more...]
China’s energy crisis: the problems with coal exit, emissions targets, and a command economy
China is also suffering from an energy crisis. Major industries have had to restrict production, and reports abound of candle-lit dinners, traffic lights failing and people getting trapped in elevators. Its effect has also been global, with Apple, Tesla, Microsoft and Dell saying it’s hitting their supply chains. As Jun Du at Aston University explains, China’s drive to cut coal has collided with post-Covid resurgent demand and an unusually hot … [Read more...]
