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...]
Don’t let high gas prices stop the EU ETS from doing its real job
The EU ETS carbon price reached a high of over €60 per tonne in September. Some are arguing that its role in the current gas price crisis is a reason why it should be reined in. But Milan Elkerbout at CEPS Policy Insights explains that the EUA (European Union Allowance) has multiple purposes. It is an incentive to invest in low-carbon solutions such as renewables, efficiencies and new methods. The sooner we pass the cost hurdle of integrating … [Read more...]
New cooling system for inverters brings electric Heavy-Duty Trucks closer
39% of greenhouse gas emissions in the transport sector comes from heavy-duty trucks. Commercial batteries struggle to deliver enough power to make electrification feasible for heavy-duty applications. Rebecca Martineau at NREL explains how a working prototype, developed with the heavy machinery manufacturer John Deere, is now getting a 378% increase in power density. The key to the innovations rests on a state-of-the-art thermal management … [Read more...]
Gas crunch: market and policy causes, and lessons learned
Andrei Belyi at the University of Eastern Finland says there are three main causes behind the huge rise in European gas prices. Everyone already understands that the reversal of the previous gas glut that gave us such low prices has been caused by a decline in European gas production, LNG imports and Russian gas deliveries. Added to that is the utilities’ reliance on spot contracts rather than termed contracts – great when prices were low – that … [Read more...]
Next German government’s climate and energy plans: what will Olaf Scholz do?
Olaf Scholz led Germany's Social Democrats (SPD) to an unexpected win in the 2021 elections held in September. He now needs to finalise a coalition with the Green Party and the pro-business FDP before forming a government and becoming chancellor. Like his predecessor Angela Merkel, Scholz has said he wants to become a "climate chancellor". Kerstine Appunn and Benjamin Wehrmann at Clean Energy Wire try to understand what his climate and energy … [Read more...]
How multi-scenario ‘emulator’ models are improving climate change projections
State-of-the-art Earth System Models (ESMs) simulate the flow of energy, moisture and chemicals through the atmosphere, ocean and land surface in unprecedented detail. But the data processing is so demanding that each scenario takes considerable time and expense to run, needing powerful supercomputers and teams of scientists and programmers to produce the models and analyse the results. “Emulators” are much simpler models that can run on a … [Read more...]
