The IEA summarises its special briefing, âThe State of Clean Technology Manufacturing.â Itâs a global update on recent progress in key regions, focussing on five technologies â solar PV, wind, batteries, electrolysers and heat pumps â critical to the energy transition. It should be read to keep decision makers informed of investment trends and the impact of industrial strategies. Overall, manufacturing capacity for these technologies is expanding … [Read more...]
Perovskite: abundant, cheap, printable solar cells demonstrated, ready to generate power
Laboratories around the world are racing to make printable perovskite solar cells, produced in abundance and so thin they can be wrapped around almost anything. Itâs a huge advantage over the typical silicon cell that is relatively big and fragile. And perovskite is much less expensive to produce. David Beynon at Swansea University describes research there that has demonstrated how a roll of plastic film can be loaded into a printing press to … [Read more...]
Five charts on the Energy Transition: the 2020s is the decade of maximum disruption. By 2030 the endgame will be clear
Sam Butler-Sloss and Kingsmill Bond at RMI present a succinct summary of why the energy transition matters, how the 2020s is the era of maximum disruption, and how by 2030 the transitionâs endgame will be apparent (though far from complete). Four key technologies are already entering the exponential growth stage: solar, wind, EVs and heat pumps. As early as 2030 their cheapness will flush away the fossil equivalents in succeeding decades, say the … [Read more...]
âExascaleâ computing algorithms can deliver new Wind Turbine designs and on-site power-maximising strategies
Advances in exascale computing algorithms and models for multiscale atmospheric flows are leading to new wind turbine designs and on-site power-maximising strategies previously not possible, explains Brooke Van Zandt at NREL. The models can contain and process two billion grid points, simulating the air flow around turbines in a large wind farm with unprecedented accuracy. Van Zandt describes how the new tools are being used to deal with highly … [Read more...]
Europe: preventing a âcarbon wallâ between the West and the ten Central and Eastern EU nations
Diana-Paula Gherasim at the IFRI Centre for Energy & Climate summarises her 36-page data-rich report on the progress and challenges for the ten Central and Eastern EU (CEECs) countries in decarbonisation. The Russian invasion of Ukraine has focussed all minds on energy security and the best solutions: less fossils, efficiency gains and clean energy made in the EU. Gherasim says that vitally important progress is being made in avoiding a … [Read more...]
Record clean-power growth in 2023: is Coal and Gas decline now structurally embedded?
Last year, wind and solar reached a record 12% of global electricity generation, according to think tank Emberâs latest global electricity review. The overall share of all forms of low-carbon electricity rose to almost 40% of total generation. Josh Gabbatiss at Carbon Brief goes through the Ember review which heralds this as the moment fossils began their permanent decline. Ember calls it âstructuralâ and âenduringâ because previous declines only … [Read more...]
Wind Turbines: how dependent is the EU on China?
Joseph Webster at the Atlantic Councilâs Global Energy Center takes stock of the European wind sectorâs dependence on China. Nobody wants geopolitics and a worsening relationship with Beijing to disrupt positive cooperation in the urgent energy transition. The news is mostly good: the dependence is low because the international trade in turbines is constrained by weight-to-value ratios, transportation costs, and local content requirements. In … [Read more...]
âGreen Deal Industrial Planâ explainer: 40%+ of the top low-carbon technologies must be made in the EU by 2030
The ECâs new series of proposed targets and reforms, contained in its Green Deal Industrial Plan, aim to ensure that at least 40% of the EUâs low-carbon technologies will be made within its borders by 2030. The eight âstrategic net-zero technologiesâ are: Solar (power and thermal); Onshore and offshore wind; Batteries and energy storage; Heat pumps and geothermal; Electrolysers and fuel cells; Sustainable biogas/biomethane; CCS; Grid … [Read more...]
U.S. IRA: what can Europe do to stop its firms relocating to America?
Thereâs been plenty of news about Europeâs worries over the U.S. Inflation Reduction Act, launched in August last year. It will deliver a broad range of subsidies, incentives and domestic manufacturing requirements that promote green technological innovation in the U.S., encompassing wind, solar, hydrogen and more, backed with a budget of $369bn. It is also designed to encourage the purchase of U.S.-made green energy products like EVs. Europe is … [Read more...]
Fulfilling U.S. wind and solar ambitions will use under 1% of its land (thatâs less than the fossil fuel footprint)
Meeting the U.S.âs wind and solar ambitions in full would take up less than 1% of its land, less than the fossil fuel industryâs current footprint. Steve Clemmer at UCS goes into the details of NRELâs comprehensive study of land use for wind and solar. Of particular interest is the observation that setting a high bar for âresponsible sitingâ of wind and solar projects - avoiding the use of sensitive, protected, urban areas, difficult terrain or … [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...]
How to protect marine mammals from the coming roll-out of Offshore Wind
The EUâs target for offshore wind is an installed capacity of at least 60 GW by 2030, and 300 GW by 2050. It will use the vast potential of the five EU sea basins, in particular the North Sea and the Baltic Sea. But growing awareness and concern over their impact on the marine ecosystem will require new methods of protecting sea life from the consequences. Isla Graham at the University of Aberdeen describes the work of her team on measuring … [Read more...]
Wind and Solar generated record 20% of EU electricity in 2022. More than gas, nuclear, hydro, coal
Now 2022 is over, the figures are in for all the main electricity generation types. For the first time ever, wind and solar delivered more electricity in 2022 than gas, nuclear, hydro or coal. In total, thatâs a record one-fifth of the EUâs electricity last year. We can thank the âtriple crisisâ of Russian gas cuts, the 500-year record droughtâs effect on hydro, and the unexpected French nuclear shutdowns for the renewed drive for wind and solar. … [Read more...]
Wind (and Solar) need their own Financial Transmission Rights to hedge their unique congestion risks
Financial Transmission Rights (FTRs) help generators and load-serving entities hedge congestion-related risk. Transmission congestion causes a divergence between wholesale power prices where it is generated and the trading hubs where it is delivered and sold. Because the congestion, and therefore the risk, varies over time it is particularly important to variable renewables. That uncertainty increases investor risk which potentially slows … [Read more...]
What’s stopping even bigger Wind Turbines? Blade speed and flexing? More likely manufacturing and installation capacity
Bigger wind turbines make cheaper energy. The sectorâs unexpectedly rapid successes in designing and building bigger and bigger turbines has been one of the major success stories of the clean energy sector. In 2023, the biggest turbines in the world will start generating electricity off the coast of the UK. Each of General Electricâs Haliade X turbines stands 260m high from sea level and can generate 13MW at under ÂŁ50/MWh (âŹ56/$61). But how big … [Read more...]
