A hydrogen ramp-up is going to be expensive and asset-heavy. So, a whole-system analysis is needed to ensure its deployment is done cost-effectively today and meets long term goals. This is what all nations committing to hydrogen are struggling with. Kelley Travers at MIT describes their modelling, in collaboration with Shell, that looks at the optimisation of hydrogen deployment in grids where variable renewables (VREs) like wind and solar are … [Read more...]
PET: a toolkit to make existing Coal plants more efficient
Many nations are struggling to phase out coal. Some, like China, are heavily dependent on it, and have more plants in the pipeline to ensure energy security and keep prices low. In other words, a lot of coal will remain in operation for the medium term. Given that, it makes sense to make them more efficient while they are in use. Daisy Chi at ECECP looks at a new set of tools – the Plant Efficiency Toolbox (PET) - that can analyse and optimise a … [Read more...]
Coal phase-out by 21 nations only accounts for 3.2% of global power. What about the others?
The 21 nations committed to coal phase-out only account for 3.2% of global electricity generation. Three - Belgium, Austria and Sweden – have already done so. The rest hope to by different dates, ranging to 2040. Asia is where the main problem is, and their transition challenges are well known: growing economies, and energy security. Carlos Fernández Alvarez at the IEA spells out their recommendations, and references case studies in Canada, the … [Read more...]
Concern over auto job losses as Europe transitions to EVs
The state premier of Lower Saxony, home of Volkswagen, says he would not tolerate a large-scale reduction in staff at Germany’s largest carmaker. There is talk of axing 30,000 VW jobs nationwide, though messages have been mixed. Benjamin Wehrmann and Sören Amelang at Clean Energy Wire look at the latest news, then summarise the implications of the EV transition for the auto industry across Europe. Highlights include the observation that a Tesla … [Read more...]
Aviation, Steel, Shipping CEOs ask COP26 to back their decarbonisation pathways
The seven “hardest to abate” industries together account for 30% of global greenhouse gas emissions. They are aviation, steel, shipping, cement, aluminium, trucking and chemicals. John Matson at RMI explains how a growing number of sector-leading corporates in aviation, steel and shipping are now openly backing net-zero pathways. He quotes CEOs and top executives (ArcelorMittal, United Airlines, Trafigura) on what they say they are determined to … [Read more...]
Compact voltage converters for integrating new DERs into the grid
The switches and converters needed to plug new clean energy technologies into the grid are going to be needed soon. The cheaper and smaller they are, the easier it will be to cope with the wide range of solutions coming down the pipe. NREL and its partners are building a megawatt-scale prototype converter that could fit the bill. They will be 1/5th the size and 1/10th the weight of existing alternatives: small enough to place almost anywhere. … [Read more...]
Surging U.S. renewables on track to take 30% market share by 2026
While the U.S. Congress debates whether backing the transition is a winning strategy, the energy sector is clearly showing the nation’s direction of travel. Dennis Wamsted and Seth Feaster at IEEFA look at the impressive growth of the clean energy champions, wind and solar. Since 2019, wind and utility-scale solar generation has risen by 76 TWh — a 31% increase — while coal and gas has fallen by 1.6%. By 2026, wind and utility-scale solar will … [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...]
IEA WEO 2021 message to COP26: 40% of clean energy goals will cut costs
The IEA’s latest World Energy Outlook was published on Wednesday. This year’s WEO-2021 is released earlier than usual to inform COP26 and, for the first time, is available for free to ensure the widest possible audience. Simon Evans at Carbon Brief offers his summary of the 386-page report, quoting relevant numbers and charts. He first points to the new scenario, Net-Zero Emissions by 2050 (NZE), as the IEA’s recognition that this is what … [Read more...]
Energy professionals: do you understand how the media works?
We energy professionals spend most of our time talking to each other. But, more than ever, climate change and the energy transition are headline news. That’s not just in the mainstream media but also within our industry journals and the policy-maker press. So, we need to understand how the media works. More specifically for many, we need to know how to handle our PR providers. Sean Crowley says it’s up to us to work more effectively with the … [Read more...]
Redesigning UK electricity taxes to boost Heat Pump sales
In the UK, consumer prices for electricity are five times more expensive than for gas. It is a disincentive to adopt electric heat pumps. To make things harder, 23% of the electricity price comes from climate and social levies. It’s just 2% for gas. No wonder the UK continues to install about 1.7 million gas boilers a year. Jan Rosenow and Richard Lowes at RAP call for changes that will incentivise customers to buy heat pumps while having a … [Read more...]
Methane Removal: an overlooked climate solution that could cut temperatures by 1°C?
If you think CO2 removal isn’t getting enough attention, methane removal is getting virtually none. There are attempts to reduce methane emissions directly from fossil fuel production. But Rob Jordan at the Stanford Woods Institute for the Environment describes studies and models that conclude we should be looking at large and wide scale reduction and capture of methane. A 40% reduction in global methane emissions by 2050 could reduce peak … [Read more...]
Green hydrogen-based fuels pivotal in decarbonising Shipping by 2050
The international shipping sector’s emission levels are comparable to Germany’s. Like aviation and heavy transport, reaching net-zero will need renewable fuels – direct electrification won’t be sufficient. Existing fossil fuel engines allow for biofuel blends of up to 20% without any modifications, and 100% methanol engines are a proven technology. Making sufficient quantities of clean fuels - without consuming food crops – is the challenge. … [Read more...]
Clean transport in Europe: key trends to watch out for
T&E’s quarterly trends series gives a snapshot of the key developments that will define the future of clean transport in Europe. And what Europe does – given it wants to lead this field – should influence what happens worldwide. T&E’s Thomas Earl brings attention to four issues. First, proven progress in this major sector makes it a contender for a significant role in Europe’s new industrial strategy. It ranges from battery and … [Read more...]
CEPP incentives and penalties: current design could undermine U.S. clean energy growth
The Clean Electricity Performance Program (CEPP) is a key part of President Biden’s energy and climate plans. It will steer utilities towards clean energy with incentives and penalties, and is still being designed. Severin Borenstein and James Bushnell at the Energy Institute at Haas, Steve Cicala at Tufts University and Ryan Kellogg at the University of Chicago warn that current proposals will allow utilities to game the system, resulting in … [Read more...]
