Avoiding curtailment made sense when solar generation was extremely expensive: don’t build solar beyond what you can store. However, that means solar must always wait for storage costs to decline and capacity grow. But with solar prices plummeting it can make economic sense to overbuild it, say Richard Perez, University at Albany, and Karl Rabago, Pace University. Oversized solar will deliver more energy in low light and reduce the need for … [Read more...]

Climate Change and the Third Energy Revolution
The anxiety expressed by young people today about Climate Change is reasonable, but they offer no thought-out solution. We should examine the available scientific options in a form accessible to those without specialised knowledge and starting from what natural science has to say about energy and where to find it. (In this article precision is set aside to allow the science underlying the orders of magnitude to be clear and simple.) … [Read more...]
Small Modular Reactors: interview with NuScale’s Jose Reyes
Dan Yurman has interviewed the co-founder and Chief Technology Officer of NuScale Power, Jose Reyes. NuScale designs and markets small modular reactors (SMRs). Its NuScale Power Module can generate 60 MW: small units, alone or combined, can suit a far wider range of energy demand than standard reactors that deliver hundreds of MWs at a minimum. The comprehensive interview covers international and U.S. developments, including plans to commence … [Read more...]
EU gas market: what China’s tariffs on US LNG could mean for Europe
Natural gas provides for around 25% of all energy consumed in the EU and is an established, if controversial, feature of the EU’s Roadmap to 2050. Furthermore, the majority of EU gas is imported and increasingly so. Combining those two factors, price and security of supply are the main issues for EU member states. So the rise of the LNG market, diversifying supply and introducing competition, alongside traditional, piped gas should be a welcome … [Read more...]
Smart Charging: parked EV batteries can save billions in grid balancing
95% of a car’s time is spent parked. It’s why parked and plugged-in EVs could be the battery banks of the future, stabilising grids powered by wind and solar. More than 1bn EVs could be on the road by 2050, their 14 TWh of EV batteries dwarfing the projected 9 TWh of stationary batteries, according to the IRENA report “Innovation Outlook: smart charging for electric vehicles”. Smart charging could therefore save billions of dollars in grid … [Read more...]
IEA clean energy progress report: Only 7 technologies/sectors on track, 38 not
Of the 45 energy technologies and sectors assessed in the IEA’s latest Tracking Clean Energy Progress (TCEP) report, only 7 are on track with the IEA’s Sustainable Development Scenario (SDS). It’s their latest and most comprehensive assessment of clean energy transitions. “On track” includes energy storage, EVs and solar PV. But buildings, car, flaring and methane emissions are still rising. This year’s TCEP puts much greater emphasis on … [Read more...]
China’s industry: Deep decarbonisation progress and challenges
Across the world, industry is regarded as a hard-to-decarbonise sector, and an emissions priority. In China it’s responsible for over 65% of its energy consumption and 70% of carbon emissions. Ji Chen and Shuyi Li of the Rocky Mountain Institute (RMI) look at the highlights of China’s efforts, and reference them against the RMI’s Reinventing Fire: China analysis. Efficiency, electrification, CCUS, hydrogen and “recycle and reuse” all play an … [Read more...]
U.S. Coal: firms go bankrupt as share of generation halves over 10 years
In the U.S. coal’s market share for power generation has halved in 10 years to 24%, from close to 50% in 2008. That year a record 1,172m tons was produced. But a combination of the rapid drop in solar and wind costs, continued competition from cheap gas, and ageing coal plants (most were built between 1965 and 1985) means that steep decline is set to continue, say Seth Feaster and Karl Cates of IEEFA U.S.. It’s why Cloud Peak Energy, the … [Read more...]
