An important part of the strategy of bringing hydrogen into the mainstream of the global energy sector is inserting it into the existing gas infrastructure. That will be done by âsimplyâ blending it with the natural gas. But there are well known challenges and uncertainties, which have been interrogated in a report from NREL and partner institutions. Hydrogen, being the smallest element, can easily permeate solid metals and render pipeline steel … [Read more...]
Analysis: U.S. IRA subsidies put two-thirds of Europeâs battery production pipeline at risk
Major battery manufacturing projects earmarked for Europe are now looking to site themselves in the U.S. to take advantage of its IRA subsidies, according to a new report by T&E. It says over two-thirds of lithium-ion battery production planned for Europe â a pipeline potential of 1.8 TWh - is now at risk of being delayed, scaled down or cancelled. The nations most at risk of losing the business are Germany, Hungary, Spain, Italy, the UK and … [Read more...]
Direct capture of CO2 from seawater: new research cuts costs, ready for pilot in 2025
Direct capture of CO2 from the air is already established in pilot phase in sites around the world, but costs are very high. So it is puzzling that capturing CO2 direct from the sea is yet to be tested properly. After all, the concentration of CO2 in seawater is more than 100 times greater than in the air, pointing at a process that should be much more efficient. David Chandler at MIT looks at research there that has uncovered cheaper and more … [Read more...]
ReDREAM: Horizon-backed project gives consumers control of local renewables, prices and demand
The ReDREAM project, funded by EU Horizon 2020, wants to put consumers at the centre of the energy market. As Steve Gillman explains, people and businesses can shape their supply and demand by owning local renewable generation and combining that with smart systems that give visibility of prices and generation to enable control of demand, right down to the level of heat pumps, washing machines, hot water systems and EVs. A 30-household pilot is … [Read more...]
EU: data shows RussiaâUkraine war has not increased Coal and emissions. Itâs quite the opposite
The Russian gas crisis has not resulted in the return of coal and high emissions in Europe, says Lauri Myllyvirta at CREA. He presents the figures that show quite the opposite. Coal returned, as expected, with the post-Covid rebound, but peaked in September 2022 below its pre-Covid level, and has been falling since along with emissions. Meanwhile, high gas prices caused by Russiaâs cut-off has kept gas demand low and, more importantly, driven the … [Read more...]
Heating Households and Buildings: Heat Pumps will be up to three times cheaper than Green Hydrogen
A new study concludes that heating from 100% green-hydrogen would be up to three times more expensive than one based on 100% electrification of buildings with heat pumps. Josh Gabbatiss at Carbon Brief summarises the findings, who says itâs yet more evidence to push back against the voices of politicians and fossil-fuel companies wanting to see hydrogen in the household and buildings heating mix (for example, the UK is planning a âhydrogen … [Read more...]
RussiaâUkraine 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. Itâs 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...]
Fast-charging lightweight next-gen lithium metal batteries: has the âshort circuitâ problem been solved?
Research into next-generation lithium metal batteries that have a solid electrolyte hold out the promise of being high in energy density, low weight, non-flammable, and can be recharged very quickly. But they can short-circuit easily. Andrew Myers writing for the Precourt Institute at Stanford University describes breakthrough experiments that reveal why. The slightest bend, twist, or speck of dust will cause imperceptible crevices in the ceramic … [Read more...]
Embodied Carbon Emissions: understanding the different methodologies being used around the world
The measurement of the embodied carbon emissions of goods tells us what greenhouse gas emissions are generated during the production and transportation of those goods. This achieves two main things. Firstly, it allows producers to understand where their emissions are coming from, and so reduce them. Secondly, it opens the door to putting a price on those emissions, thus incentivising producers to reduce them. But, as Max Gruenig at E3G explains, … [Read more...]
Will Europe now commit to long term imports of large quantities of LNG?
The EU and European nations need a more secure LNG supply strategy than just buying on the spot market where there is little control of prices and quantities. With Russian gas off the agenda for the foreseeable future, itâs LNG thatâs filled the gap. But spot prices have been extremely high, and may return to the same heights. And though Chinaâs Covid-caused drop in LNG consumption helped enable Europe to buy enough for now, that wonât be the … [Read more...]
New AI model predicts 1.5C temperature rise is likely in 2030s even if emissions decline
A new artificial intelligence model is predicting that 2C warming is likely to occur and sooner than expected, even if current low-emissions strategies are successful, explains Josie Garthwaite at Stanford University. The Stanford-developed AI uses âneural networkâ learning from vast quantities of past data, predicting that the 1.5C threshold is likely to be crossed in the next 10 to 15 years. Thatâs regardless of how much greenhouse gas … [Read more...]
Germany is developing a strategy for Carbon Capture and Storage to meet its 2045 net zero target
Germany cannot become carbon neutral by 2045 without carbon capture, explains Simon Göss at carboneer. Itâs why the German government is developing a Carbon Management Strategy for CO2 storage and utilisation. Projections reveal that around 30m tons of CO2 will have to be captured, transported, reused or disposed of by 2045. The focus will be on industrial processes and waste. Göss lays out the background to Germanyâs strategy, including possible … [Read more...]
Will the computing power needed for self-driving cars create a carbon emissions problem akin to data centres?
Few predicted, in their early days, that the scale-up of data centres would result in them having a measurable impact on global energy consumption. Today they contribute 0.3% of global emissions. Thatâs a big enough number to put it on the global radar and for the IEA to be monitoring it. Will the wide scale take-up of autonomous vehicles have the same effect? Yes, explains Adam Zewe at MIT who describes new research from there. In summary, one … [Read more...]
Coal phase-out: Developing world targets are unfeasible. Rich nations must cut emissions faster
Developing nations like China, India and South Africa are being asked to phase out coal more than twice as fast as any comparable energy phase-out in history, for the world to meet the Paris climate goals. Thatâs simply unrealistic say James Price and Steve Pye at UCL who present the results of their new study. Instead, rich nations will have to reduce significantly their oil and gas to compensate for the shortfall. An oil and gas peak isnât good … [Read more...]
Big Consultancies are now advising on climate change. Will it conflict with their business-as-usual work?
The worldâs top management consultancies - like BCG, Accenture, PwC, EY, McKinseys - who for decades have advised the biggest polluters, are now rushing into the business of helping companies cut emissions to become more sustainable, explains Emma Thomasson at Clean Energy Wire. The necessary expertise is in very short supply, so they are retraining staff, poaching environmental experts, and buying up smaller specialist firms. BCG is even running … [Read more...]
