To pile on the pressure over climate negotiations, the UN Secretary General Antonio Guterres is convening a special Climate Action Summit, starting today. Nations are being pressed to accelerate their ambitions and back them up with concrete and realistic plans. The summit will be focussed on six ‘action areas’: energy transition; industry transition; infrastructure, cities and local action; nature-based solutions; resilience and adaptation; … [Read more...]
UN climate summit: which nations are leading, which failing
Ahead of the UN climate summit in New York on September 23rd, where countries are expected to set themselves more ambitious targets and roadmaps than they did in Paris in 2015, Bill Hare of Climate Analytics looks at the emissions league table. There are some surprises at the top: Ethiopia, Morocco and India, though he points out being at the top can still be a long way from doing enough to meet the 1.5℃ goal. At the bottom are Australia, the … [Read more...]
China’s quest for gas security is reshaping the global LNG market
In just two years, China has become the world’s top gas importer and should soon become the largest importer of Liquefied Natural Gas (LNG). But that growing import dependency, domestic winter supply concerns, and the trade war with the U.S. means the Chinese government is reinforcing its gas supply policy, says a report "China’s Quest for Gas Supply Security: The Global Implications" by the IFRI Centre for Energy & Climate, authored by … [Read more...]
Accelerating electromobility in east Europe: a how-to guide (part 1)
While record electric vehicle (EV) sales in high income countries keep making headlines they’re struggling to take off anywhere else. Sarah Keay-Bright plots a pathway for change. Like anywhere else, public investment must come first, carefully paving the way for private to follow. So that means getting the tax regime right. As taxes rise to disincentivise fossil cars those revenues will fall as people go electric. So they need to be replaced. … [Read more...]
U.S. nuclear plants to produce carbon-free hydrogen
Nuclear is under severe price pressure from renewables now, as well as gas.But rather than throw the decades of investment and knowledge away, the U.S. Department of Energy is launching three first-of-a-kind projects designed to improve the long-term economic competitiveness of the nuclear power industry. Three commercial electric utilities and Idaho National Laboratory have been chosen to adapt plants to make hydrogen by electrolysis, 100% … [Read more...]
Grid balancing: Electric Cars are a lot like water heaters, so relax
Electric water heaters consume as much power as electric cars, drawing on the grid in much the same way: everyone’s doing it at roughly the same time of day. The U.S. already has 60m such heaters and manages to balance the grid with no problem. So adding tens of millions of electric cars should be very manageable even without direct control of when the cars charge, says Jim Lazar at the Regulatory Assistance Project (RAP). It only takes two to … [Read more...]
Can other technologies replicate Solar PV price reductions?
Catherine Wolfram at the Haas School of Business reviews the new book “How Solar Energy Became Cheap” by Greg Nemet. It traces Solar PV’s history from Bell Labs in 1954 through to the present. The phenomenal price drops mean today’s cost/kWh is 1,000 times lower than in the 1970s. The analysis is split into four epochs when output was dominated by US, Japanese, then German and finally Chinese production. How much were improvements thanks to sheer … [Read more...]
New EU green investment rules to make conservative German savers bite
Germany’s past renewables successes have been underpinned by government and public funds and guarantees. Its future will depend more and more on private investment, which means citizens and small investors must opt to put their money into green investments and take on risk. The good news is that surveys show citizens are very willing. The bad news is that few are actually doing it. Is it because the banks aren’t promoting sustainable investments, … [Read more...]
UK fracking earthquakes: why the world’s “toughest” safety rules failed to predict them
In August this year Lancashire experienced the largest fracking-induced earthquake recorded in the UK. Fracking was suspended. Legislators discussed a complete ban. As a result, serious questions are being asked about the effectiveness of the safety regulations, given the operating company, Cuadrilla, predicted there was a “low-likelihood” of such events occurring. And given the UK’s “traffic light system” (TLS) is the most stringent TLS in the … [Read more...]
Lightweight Gasoline Cars: a necessary 30-year stop gap?
We should all be driving electric vehicles. But we have to wait for renewable electric grid capacity to support them all, charging points everywhere, and enough new batteries to be manufactured and put in all the new, affordable BEVs. And we’re running out of time. An interim solution has come from a study by MIT and Ford. David Chandler, writing for MIT, explains the study, which says that an interim solution – for certain regions - is … [Read more...]
China’s Solar Paradox: why invest today when prices keep dropping?
Josh Gabbatiss at Carbon Brief reviews a paper published in Nature Energy, showing how grid parity is already achievable today, subsidy-free, across all China’s 344 biggest cities. Consequently, China is already reducing solar subsidies and realigning policy to de-emphasise scale and re-focus on quality. So far, so good. But China now joins those developed nations where cheaper solar has thrown up another problem: why spend now when it’ll be … [Read more...]
2018 investment in renewables 12% down on 2017
At $272.9bn, 2018 investment in renewables capacity was 12% down on the previous year. Despite this, renewables’ investment was three times the total for coal and gas-fired generation capacity combined in 2018. Over the last decade, $2.6tn was invested in renewables (half going to solar), quadrupling capacity to 1,650GW. Consequently, renewables’ share of electricity generation reached 12.9%, up from 11.6% in 2017. This avoided an estimated 2bn … [Read more...]
An independent Global Energy Forecast to 2050, to compare with the IEA’s WEO 2019
Schalk Cloete is creating his own Global Energy Forecast to 2050. He wants to see how his own independent analysis will match up with the next IEA World Energy Outlook, due in November. And so do we. Rich with data, his major predictions include a global policy shift from technology-forcing to technology-neutrality shortly before 2030, driven by growing worldwide acceptance of the severity of climate change. The exhaustion of the 1.5°C and, … [Read more...]
Can Vanadium Flow Batteries beat Li-ion for utility-scale storage?
It’s taken 40 years for lithium-ion battery technology to evolve into its current state, powering everything from the smallest electronic devices to Tesla’s 100MW battery farm in southern Australia. But utility-scale Li-ion batteries are rare. 99% of grid storage today is pumped hydro, a solution that will always be limited by geographical and environmental constraints. For utility-scale chemical batteries to take off they need a new technology, … [Read more...]
“Hard-to-abate” sectors need Hydrogen. But only 4% is “green”
40% of global greenhouse gas emissions come from “hard-to-abate” industry sectors like industrial processing and transport. Electrification won’t be enough. They also need hydrogen, argue Patrick Molloy and Leeann Baronett at Rocky Mountain Institute. Hydrogen production is already well established and growing. But it’s mainly for the chemical industry, which never meant it to be “green”: sure enough, only 4% of current hydrogen production is … [Read more...]
