The security of supply of gas has been the hottest topic of the last 12 months since Russia invaded Ukraine. James Kneebone at the Florence School of Regulation (FSR) has written an explainer that lays out the EU’s history of dealing with energy security, going back to the 1990s. Because the EU has a single market for natural gas and widely shared value chains (pipelines, LNG terminals, storage, etc.), impacts are felt across the bloc. But that … [Read more...]

Can Enhanced Geothermal Systems be used as grid-scale batteries? Anywhere!
The US Department of Energy aims to cut the cost of Enhanced Geothermal Systems (EGS) by 90% by 2035. Standard geothermal power comes from tapping existing hydrothermal reservoirs. But most places don’t have hot water reservoirs underground. EGS pumps water down to reach hot rocks, heating the water to achieve the same purpose. Everywhere has hot rocks underground. Here, Stefan Ellerbeck, writing for the World Economic Forum, describes research … [Read more...]
European gas prices have fallen sharply since August. What happens next?
Prices on the European gas market have fallen sharply since August 2022 and Europe’s gas storage facilities are almost full. That’s good news, but the problems aren’t over. Simon Göss at cr.hub, writing for Energy Brainpool, explains why by looking at the data. He runs through the main factors driving the changes, primarily strong LNG imports, Norway’s increased production, mild weather, and lower gas consumption (particularly in industry). … [Read more...]
Pollution costs are driving U.S. states to look for alternatives to Gas-Fired Plants
In the U.S. a growing number of states and regulators are directing utilities to look for alternatives to proposed gas-fired power plants, citing environmental justice and community health impacts, explain Caitlin Odom and Lauren Shwisberg at RMI. So it’s not just about emissions: pollution matters too. The authors quote studies that show clean energy portfolios (CEPs) not only reduce energy costs, but can save billions of dollars in community … [Read more...]
U.S. Residential Distributed Solar: still getting cheaper, installation and permitting too, more batteries
John Rogers at UCS reviews the new and comprehensive “Tracking the Sun” report from Lawrence Berkeley National Laboratory which covers both residential and non-residential “grid-connected, distributed” solar PV systems in the U.S. There has been clear progress across the board, including PV module efficiency, system costs, installation and permitting, and the uptake of batteries. For example, median efficiency for modules in residential systems … [Read more...]
Aluminium, sulphur and salt batteries. Cheaper than lithium-ion, for homes and EV charging stations
The high and escalating demand for the lithium-ion batteries that dominate the market is driving the search for alternatives. Ideally, they will be made from inexpensive, abundant materials. David Chandler at MIT describes research there into a design that uses aluminium and sulphur as its two electrode materials, with a molten salt electrolyte in-between. The results point at batteries that have a projected cost per cell of about one-sixth that … [Read more...]
“GETs”: 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 – the pipeline of clean generation projects … [Read more...]
Can China’s 14th 5-year-plan for Renewable Energy deliver an early emissions peak before 2030?
At the beginning of June China released its 14th five-year plan (FYP) for renewable energy for the five years 2021-2025. Hu Min at Innovative Green Development Program, writing for Carbon Brief, reviews the plan’s targets and actions, and its implications. Unchanged from the 13th FYP, 25% of China’s energy will come from non-fossil sources by 2030. But the 14th FYP says at least half of the increase in electricity demand will be covered by … [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 you’re 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...]
If Russia cuts off its gas supply can we achieve EU storage targets for winter?
Calvin Triems at Energy Brainpool summarises their analysis of whether and how Europe can achieve its storage targets for 2022. There are four scenarios: “Base Case”; “Nordstream@40%” where there’s no change to Russia’s mid-June gas flow cut to 40%; “Nordstream@40% + No Freeport” where the unexpected fire in early June at the U.S. Freeport LNG terminal remains unresolved for months; “Nordstream@0% + No Freeport” where Russia cuts off supply … [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. What’s 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...]
New thermophotovoltaic cells turn heat into electricity more efficiently than a steam turbine
Over 90% of the world’s electricity comes from heat-generating power plants using coal, natural gas, nuclear energy, and concentrated solar energy. Steam turbines have always been the standard for converting that heat into electricity. On average they are only 35% efficient, with moving parts that cannot cope with temperatures above 2,000 degrees Celsius. Jennifer Chu at MIT describes new research, in collaboration with NREL, that has led to a … [Read more...]
If Russia cuts its gas supplies to Germany, what happens next?
Replacing Russian pipeline gas to Europe in the short term is much more difficult than finding alternative sources for coal and oil. It’s why the EU hasn’t banned Russian gas. But what if Russia cuts off the supply? Benjamin Wehrmann at Clean Energy Wire looks at what the consequences and options are for Germany. Though Germany aims to wean itself off Russian supplies almost entirely by 2024, a sudden cut would have serious consequences. Storage … [Read more...]
