William Todts at Transport & Environment is very worried about the Biden administration’s approach to aviation and shipping emissions. The signals are that the U.S. wants to work through the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). But they have neither the ability nor the means to spur technological breakthroughs. That matters, because it’s only the use of alternative fuels that can … [Read more...]
A marketplace for energy data will enable Europe’s grid expansion
The growth of the decentralisation of energy generation and storage combined with the digitalisation of the metrics of supply and demand is pointing towards a marketplace for energy data, explain Veronika Spurná and Helena Uhde at the EU-China Energy Cooperation Platform. Such a marketplace will monetise the data itself, in recognition of its vital role in enabling the intelligent distribution of energy and investment. There will also be a place … [Read more...]
Policy-makers still undervalue Energy Efficiency as a grid resource
Supply-side solutions to grid stability are few in number, and expensive. More baseload generation, electricity networks, capacity markets that pay power plants all year round to be available for dispatch during a few peak hours. Demand-side solutions are usually smaller, and multitudinous: building fabric improvements, equipment upgrades, customer behaviour interventions, and more. So, for grid stability, the principle of “Efficiency First” - … [Read more...]
We’re making much more progress decarbonising Electricity than Transport. Why?
In the OECD, since 2000, electricity sector emissions have fallen by 8% while transport emissions have actually increased by 5%. The best performers like the UK recorded drops in both: 40% and 6% respectively. In the U.S. it’s 25% and 0%. Catherine Wolfram at the Haas School of Business asks why transport is still going in the wrong direction, given the power sector’s progress. She posits three theories. Rich nations are outsourcing … [Read more...]
Quantum Well solar cell sets new record for converting light to energy
There’s a new world-record for two-junction solar cells, converting 32.9% of sunlight into electricity. Although it’s only a small improvement on the previous record of 32.8% it uses a design that should lead to even greater performance. NREL, in collaboration with the University of New South Wales (Australia), has built a cell consisting of a series of more than 150 ultrathin layers of alternating semiconductors that create quantum wells which … [Read more...]
Coal regions are ideally suited for utility-scale Wind, Solar and jobs
Over 15% of total greenhouse gas emissions in the EU come from coal-fired energy generation. 18 EU countries still use coal for electricity production. The argument goes that the phasing out of coal threatens the livelihoods of coal workers and their regional economy. But it should be the opposite, argue Elif Gündüzyeli and Jörg Mühlenhoff at CAN Europe. Coal regions are ideally suited for new gigawatt-scale wind and solar. They already have the … [Read more...]
How do we get EV payback periods down to 4 years?
The take-off of EVs will happen when the lifetime cost of ownership falls below that for a conventional car. But let’s remember that “lifetime” for a Brit means 4 years as that’s the average period of ownership. Gerard Wynn and Arjun Flora at IEEFA show how the payback period on Gerard’s Renault Zoe ZE50 has been cut by over a fifth simply by signing up to a smart meter tariff. It’s dropped from 10 to 8 years. The UK is nearing the universal roll … [Read more...]
IEA’s “accelerated case” becoming the norm? Global Wind + Solar to overtake Gas and Coal by 2024
The IEA’s 2019 “accelerated case” for renewables is turning into this year’s “main case”. It predicts that Wind and Solar capacity combined will overtake both Gas and Coal globally by 2024. Josh Gabbatiss at Carbon Brief summarises the IEA’s Renewables 2020 report. Within five years, renewables will constitute 1/3 of all electricity generation, equivalent to the combined demand of China and the EU. Virtually all global growth in electricity … [Read more...]
Solar is displacing Coal in India’s electricity market
India is the world’s third largest electricity market and as a fast-growing economy can, according to the IEA, lead the recovery of global energy demand out of the pandemic for the coming decade. Kashish Shah at IEEFA runs through solar’s prospects in India, which hopes to build 450GW of renewable energy by 2030. Solar is getting cheaper. A 2GW auction in June delivered India’s lowest-yet renewable energy tariff at US$31/MWh. That figure could … [Read more...]
Which sectors need Hydrogen, which don’t: Transport, Heating, Electricity, Storage, Industry?
Which sectors are most suited to hydrogen, and which are not? For the answer, six academics from the UK and the Netherlands - Tom Baxter, Ernst Worrell, Hu Li, Petra de Jongh, Stephen Carr, and Valeska Ting – use their areas of expertise to neatly summarise hydrogen’s pros and cons in Road and Rail, Aviation, Heating, Electricity and Energy Storage, and Heavy Industry. Their general message seems clear: hydrogen is still very expensive, so it can … [Read more...]
5 charts show the rapid fall in costs of renewable energy
Plenty in the energy sector already know about the impressive declines in renewable energy costs since 2010, particularly solar (down 82%), concentrated solar (47%), onshore (39%) and offshore wind (29%). For those of you putting together presentations to people whose buy-in you need - citizens, public officials, investors, customers, etc. - these graphics should come in useful. It looks like a tipping point is being reached, says Douglas Broom … [Read more...]
The benefits of Peer-To-Peer Electricity Trading for communities and grid expansion
The adoption of peer-to-peer (P2P) electricity trading will turn individual consumers from passive to active managers of their networks. Such a marketplace can relieve constraints on the growing system and offer an alternative to costly grid reinforcements. Arina Anisie and Francisco Boshell at IRENA run through the benefits, including investment costs, bills, resilience, congestion, mini-grids, energy access, and more. They note that very few … [Read more...]
Battery innovation must drive the 50-fold increase in storage capacity needed by 2040
The IEA has set the storage sector a challenge. It says the world will need 10,000 GW-hours of batteries and other forms of energy storage by 2040, a 50-fold increase on today. The good news is that a joint study by the European Patent Office and the IEA reveals electricity storage patenting activity has grown 14% a year over the past decade. Here the IEA summarises the findings of its comprehensive report. It explains that Japan and Korea lead, … [Read more...]
ELCC: how to measure grid stability as renewables are added
We cannot just swap 24/7 fossil fuel power plants for intermittent renewables. To prevent electricity shortfalls the capacity of a solar or wind plant must exceed that of the fossil fuel plant it replaces. But by how much? That’s the question that the Effective Load Carrying Capability (ELCC) metric is designed to answer. It’s not a new concept, but is now becoming very important. Mark Specht at the Union of Concerned Scientists explains the … [Read more...]
How ready is the switchgear industry to abandon SF₆, the worst greenhouse gas?
Are firms in the switchgear industry - power utilities, industrial sites, and related service and infrastructure sectors - happy to switch from using the gas SF6 and use alternatives that are less harmful to the climate? This is the question Marie-Charlotte Guetlein and Carine Sebi at the Grenoble École de Management asked over 400 switchgear customers to find out what’s needed to make the change. SF6 has 23,500 times the impact of CO2 and an … [Read more...]
