It is well known that evaporation and radiation are two ways of keeping something cool. David Chandler at MIT explains how researchers there have created an experimental 3-layered cell that combines evaporation and radiation with an insulator to deliver cooling that needs no power. It can provide around 9°C of cooling from the ambient temperature, enough to permit safe food storage for about 40% longer under very humid conditions, and could … [Read more...]
Is a Carbon Tax the best way to decarbonise the Grid?
Severin Borenstein at the Energy Institute at Haas and Ryan Kellogg at the University of Chicago question whether carbon pricing is the best way to decarbonise the electricity grid. The authors did an empirical analysis of all of the fossil plants in the US. It shows that a CES (clean electricity standard) or zero-emissions subsidies would close down fossil plants in almost the same order as a carbon tax. So using alternative policy tools can … [Read more...]
âGETsâ: cheap ways for Grids to double Wind & Solar integration and help battle global inflation
Accelerating the clean energy transition can tackle the inflation crisis, not just save the climate, explain Russell Mendell, Mathias Einberger and Katie Siegner at Rocky Mountain Institute. Rising energy costs are driving current global inflation. So now is the perfect time to drive through low-hanging-fruit ways to increase wind and solar generation and storage. In the U.S. interconnection queues â the pipeline of clean generation projects … [Read more...]
Gravity Batteries: any nation can do it at scale using rocks
The beauty of gravity batteries is that they simply involve lifting (charging) and lowering (discharging) a heavy weight, explains Simon Read writing for the World Economic Forum. For pumped hydro, access to water and a geological height difference is needed. But if youâre using rocks or bricks, anyone can do it anywhere, and at any scale. The rest is just a construction job. No rare materials or minerals will ever be needed, nor chemicals that … [Read more...]
Grid Distribution Systems: access to usage data is uncovering the optimal design for future electrification
The more efficient a distribution grid is, the less likely other potential supply bottlenecks (from lithium for batteries to trained electricians) will slow the transition to greater and greater electrification. State-of-the-art modelling of future grids is already happening, but the robust modelling of the distribution system is conspicuously missing because good data are notoriously hard to find, says Meredith Fowlie at UC Berkeleyâs Energy … [Read more...]
Record global clean energy spending, but itâs still not enough and costs are rising
Since 2020, clean energy investment has grown by 12% per year â it was only 2%/year during the five years after the 2015 Paris Agreement. That boost is the main reason why total global energy investment is set to reach $2.4tn in 2022, according to the latest âWorld Energy Investmentâ report from the IEA. Itâs very good news that spending on solar PV, batteries and EVs is now growing at rates consistent with reaching global net zero emissions by … [Read more...]
Event summary: â45% RES by 2030: EUâs latest investment challenge to DSOsâ
Sara Stefanini provides a written summary of our panel discussion held on Thursday June 30th 2022. Itâs a full summary of the 90 minute discussion (including audience questions), but it begins conveniently with a summary of the highlights. Investment in and the modernisation of the electricity distribution grid is one the biggest challenges the EU has to overcome in the next decade. Itâs a âŹ400bn investment challenge by 2050 says Eurelectric, an … [Read more...]
4 ways to cut whole system electricity costs with flexible Demand Side Management
Right now, energy system costs are driven by generation capacity, infrastructure upgrades, network reinforcements, curtailment and constraint payments, and imbalance costs. Whatâs missing is the investment in a raft of demand side management assets that are ready to go but are not part of the market, therefore not rewarded, and therefore not being invested in. Laura Sandys at Energy Systems Catapult, writing for WEF, explains why flexibility must … [Read more...]
Manifesto: fit-for-purpose flexible grids for the clean electrification of Europe
The integration of new clean generation sources on top of the increase in electrification of industry, e-mobility, and heating and cooling means grid investment must be made a priority. Anything else will leave deployment-ready solutions waiting, slowing down the transition. The backdrop is that over one third of the EUâs grids are already more than 40 years old. Eurelectric has produced a manifesto, âConnecting The Dotsâ, that estimates … [Read more...]
Event Summary: âCHINA: Carbon Neutral by 2060 â Innovationâ
Here are the highlights of our 2-day 4-session workshop âCHINA: Carbon Neutral by 2060 - Innovationâ, compiled by Sara Stefanini. Itâs a quick and efficient way for readers to see the main points made by our expert panellists. Held at the end of May, it was the fourth of our EU-China workshops since the first was held in November 2020, produced for the EU China Energy Cooperation Platform (ECECP). As always, leading speakers from the EU, major … [Read more...]
Will Chinaâs gigantic wind and solar âbasesâ mean targets met four years early?
China will have doubled its 2020 installed wind and solar capacity by 2025, exceeding 1,100GW, according to government plans. Thatâs four years sooner than required to meet their target of peak CO2 emissions by 2030 and carbon neutrality before 2060. Writing for Carbon Brief, Lauri Myllyvirta and Xing Zhang at CREA explain that the main driver is the creation of âclean energy basesâ: large-scale concentrations of wind and solar power on deserts … [Read more...]
Chinaâs impressive growth in Renewables and Transmission now needs Market innovation
***REGISTER NOW for CHINA: Carbon Neutral by 2060 - INNOVATION*** - China has the worldâs largest power plant fleet for both coal and renewables. Together they make up most of the total power capacity of over 2,200 GW... STOP PRESS: China's Transition is the biggest single opportunity for managing climate change and also for those businesses who are ready with the innovations that will ensure the best possible outomes in an incredibly … [Read more...]
Solar + Storage Hybrid plants are poised for explosive growth in the U.S.
At the beginning of 2021 the U.S. had 73 solar and 16 wind hybrid projects, amounting to 2.5GW of generation and 0.45GW of storage. By the end of 2021, over a third of the 675GW of solar in the grid connection queue were hybrids, and 19GW were wind hybrids. Only one in four typically get approved, built and connected. But that still points at a twenty-five-fold increase in hybrid generation. Itâs why Joachim Seel, Ben Paulos and Will Gorman at … [Read more...]
Q&A: How fast can renewables deliver on Germany’s new energy independence goals?
How quickly can Germany reduce its dependence on fossil fuels? Benjamin Wehrmann at Clean Energy Wire asks six practical questions that must be answered, then gathers the expert answers. What are the current expansion goals for wind, solar and other renewables? Following Russiaâs invasion of Ukraine, will the new emergency plans bring an end to Russian imports as well as reach climate targets? Are renewable power companies ready to deliver a fast … [Read more...]
âFloato-voltaicsâ: floating solar farms on existing municipal water reservoirs
The municipality of Cohoes, population 17,000, in New York State, is building a floating solar farm on its 10-acre water reservoir. It should power all the city-owned buildings and streetlights, save $500,000/year in electricity costs and still leave 40% of the generated electricity remaining for other civic use. It will cost $6m. It will be a first for a U.S. city, explains Connor O'Neil at NREL. The case for city âfloato-voltaicsâ is so … [Read more...]
