Carbon Capture is the Transition’s great unknown. Big targets have been set but nobody knows how we’re going to meet them. It's clear we need utility-scale breakthroughs, and fast. And cheap. We take a look at one example of cutting edge research that could deliver both. Scientists at the U.S. Department of Energy’s SLAC Laboratory and Stanford University have taken the first images of CO2 molecules captured within a highly porous nanoparticle … [Read more...]
Gas v Electric new buildings: U.S. standards agency backs gas with out-of-date data, says RMI
Official reports matter. That’s why the Rocky Mountain Institute (RMI) is taking to task the U.S.’s National Institute for Standards and Technology (NIST) which published a paper stating that all-electric systems are more carbon intensive and more costly than gas-fired systems in new buildings. The NIST paper assumed a high reliance on coal as the primary source for electricity generation in their Maryland case study. Those stats are out of date, … [Read more...]
Utility-scale batteries can undercut peaking gas and coal
A report by IEEFA looks at trends in the U.S. to install utility scale batteries. The report’s author, Dennis Wamsted, gives examples of how it is replacing the peaking and seasonal generation being provided by gas and coal. Emissions aside, the numbers are starting to add up. In Hawaii the combination of solar generation and storage is expected to undercut the price for fossil fuel generation. In Texas, Vistra Energy’s batteries are soaking up … [Read more...]
Carbon-emitting gas, not renewables, is replacing U.S. nuclear
Ohio, USA, subsidises renewables. Now the Ohio State Legislature is fighting over a bill that will re-shape and extend that support to all clean energy, including nuclear. That’s how it should be, says Jim Conca. He reviews a report by regional transmission organisation PJM that says keeping nuclear plants open is far cheaper. Moreover, it’s far better for emissions. That’s because whenever a nuclear plant is shut down in the U.S. it is replaced … [Read more...]
BP Review of 2018: record CO2, energy use as gas outstrips wind & solar
Energy use grew at 2.9% in 2018, the largest rise since 2010. It’s what happens when economies grow. But gas, oil and coal's contribution to that growth saw global CO2 emissions rise by 2% in 2018, the largest year-on-year increase in seven years. Wind and solar growth, driven by China though slowing in the US, EU, and India, achieved its second fastest rate on record - but still lagged behind gas additions. These are not the trends we need to … [Read more...]
$400bn in global fossil fuel consumption subsidies, twice that for renewables
At over $400bn in 2018, global fossil fuel consumption subsidies are more than double those for renewables. That makes sense while governments worldwide use energy subsidies to help poor consumers, and clean energy still makes up a smaller proportion of the global energy mix. But it makes the transition harder: cheaper fossil energy means more is consumed, and it’ll take longer for clean energy to compete it away. The IEA’s WEO Energy Analysts … [Read more...]
U.S. sanctions against Nord Stream 2: the global realpolitik of Russian gas for Europe
The proposed US sanctions aimed at Nord Stream 2 (NS2) are yet another hurdle in the way of the controversial Russian gas pipeline for Europe. But they are not an attempt by the Americans to prevent Gazprom from supplanting them as a supplier, says Alan Riley at the Atlantic Council Global Energy Center, because NS2 will deliver no more gas than the current route via Ukraine, just replace it. He argues the sanctions are to constrain Russia’s … [Read more...]
New gas-to-methanol technology OxE could end oil well “flaring”
Oil wells also release natural gas. But it’s burnt off on site whenever the economics of collecting and piping it don’t add up (gas can’t use the existing petroleum infrastructure). What if it could be converted into methanol, says Nichole Liebov at the University of Virginia. She describes a new process called oxyesterification (OxE) that converts methane (the main constituent of natural gas) into methanol cost effectively at low temperatures … [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...]
IEA: Global energy investment stabilises at $1.8tn after 3 years of decline
Three consecutive years of declining global energy investment has ended. But it’s not risen, just stabilised at $1.8tn, according to the IEA’s latest report World Energy Investment 2019. To meet the Paris targets investment in efficiency needs to rise substantially, and double by 2030 for renewables: they have stalled for both. To meet soaring global energy demand oil and gas investments need to rise too. That demand is seeing cheap coal still … [Read more...]
UK oil & gas keeps rising. Clean Energy blueprint can reverse it
In the UK the £2.3bn (=$2.9bn / €2.6bn) in new oil and gas subsidies introduced since 2014 will state-fund the addition of twice as much carbon as its coal phaseout saves, says a new report “Sea Change: Climate Emergency, Jobs and Managing the Phase-out of UK Oil and Gas Extraction”. Can the UK call itself a climate leader if its existing policies push it over its emissions limits? It can, if you consider this: the UK took 16 years to become the … [Read more...]
Carbon Capture: Can CO2-EOR really provide carbon-negative oil?
Enhanced Oil Recovery (EOR) injects CO2 into oil reservoirs, increasing the pressure and forcing the oil out. 20% of global oil production uses EOR. But if that CO2 doesn’t stay underground it hasn’t been captured. If it was itself extracted from natural underground CO2, there is no benefit – or worse. Ideally, it should come from already captured CO2. But most oil wells are nowhere near a CCUS (carbon capture, usage and storage) facility: in the … [Read more...]
50% Hydrogen for Europe: a manifesto
Electricity has well known limitations, mainly for bulk and long-range transport, industrial processes requiring high temperature heat, and the chemicals industry. To entirely replace fossil fuels we need hydrogen, say Frank Wouters and Prof. Dr. Ad van Wijk. It has an energy density comparable to hydrocarbons. There's more: Europe’s electric grid can’t cope with 100% electrification, yet hydrogen would use the existing gas pipe networks. The … [Read more...]
Developing World: cashflow analysis shows gas, coal far more profitable than clean energy
80% of future energy infrastructure will be built in the developing world. Schalk Cloete has already written for us on the purely economic viability of developed world onshore wind, utility-scale solar PV, nuclear, natural gas and coal. He now presents his detailed cashflow analyses of the major generator technologies applied to the developing world. Because costs tend to be much lower the returns are higher. But gas and coal still easily … [Read more...]
EU election risk: policymakers should go for real decarbonisation now while efficiency savings can help
With elections in May, the balance of opinion in Parliament is a climate policy risk factor on the minds of many in Brussels. The national draft 10-year energy plans, just in to the Commission, project widespread growth in costlier renewables. But populists who see climate as a globalist rather than nationalist-first agenda may prove hard to bring on side with an expensive and disruptive transition. The public will be influenced by climate … [Read more...]
