PGE Polska Grupa Energetycznaâs goal is to have at least 6.5 GW of offshore wind capacity in the Baltic Sea by 2040. The first projects will come online within the next few years. The offshore projects are one of PGEâs key steps towards climate neutrality, and PGE hopes to become a leader in offshore wind in Poland. Here, Wojciech DÄ browski, PGEâs President of the Management Board, answers questions to explain their strategy, and how it fits into … [Read more...]
How to ramp up Hydrogen under the new REPowerEU targets
What needs to be done to develop hydrogen as a major fuel in Europe as the continent looks to diversify away from Russian oil and gas supplies? The war in Ukraine has led to the EU substantially raising its hydrogen ambitions. While the earlier âFit for 55â target for 2030 was set at 5.6 Mt, the new REPowerEU strategy has increased the target to 20 Mt, to replace 50 bcm of Russian gas. That means, for example, the use of hydrogen in industrial … [Read more...]
Summer break! See you in September

Weâll be back in September with our articles, as well as more events discussing the key challenges faced by this sector. Do get in touch if you have suggestions for particular event topics, can bring expert knowledge to our panels, or are interested in sponsoring. Meanwhile, our readership has more than … [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...]
Can Chinaâs 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 planâs targets and actions, and its implications. Unchanged from the 13th FYP, 25% of Chinaâs 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 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...]
Hydrogen project pipelines need new ways of matchmaking investors and developers
What is required to catalyse private investment in the new hydrogen economy? Isabelle Huber at the Center for Strategic and International Studies has looked at a European Investment Bank survey of hydrogen investors in the EU to find some answers. One obvious challenge is the cost of moving to hydrogen. An example of dealing with this is Germanyâs H2Global mechanism which uses government funds to bridge the gap. But another major problem … [Read more...]
What will an international marketplace for Hydrogen look like?
Though any nation can in theory make its own hydrogen, some will be able to do it much more cheaply than others. Herib Blanco at IRENA summarises their study that looks at the factors that determine the difference, along with the hydrogen transport costs that will influence the global trade that should emerge. By 2050, those transport costs could reach levels below $1/kgH2 once economies of scale are reached and supply chains are fully developed. … [Read more...]
Clean Turquoise Hydrogen: a pathway to commercial readiness
Whereas blue hydrogen from methane produces CO2, the by-product of turquoise hydrogen is pure carbon. The obvious advantage is you can make your hydrogen without the need for expensive new infrastructure to transport and store any CO2. Turquoise hydrogen is only at the start-up phase, so Schalk Cloete summarises his co-authored paper that looks at various scenarios to estimate the cost of producing the hydrogen (using molten salt pyrolysis) and, … [Read more...]
EVs vs Biofuels: new study looks at ethanolâs impact on agricultural land use, food prices, emissions
For transport, biofuels have lower emissions than gasoline/petrol, but EVs will have the lowest emissions of all. Hence the opposition to those biofuels, along with objections to the valuable cropland used to make the ethanol. But the overall advantage depends on the speed of transition to EVs charged with clean electricity. Now, a calculation has been made of the amount of agricultural land preserved for global food production - or kept as … [Read more...]
New research into making water boil using less energy
Can the boiling of water be done more efficiently? If so, a wide range of processes can save energy, not least the standard use of steam turbines in electricity generators. David Chandler at MIT describes research there that modifies the surface of the heating element. A combination of microscale dents and nanoscale bumps and ridges on the surface, and pillars that allow the âwickingâ of water by capillary action, improves the efficiency of … [Read more...]
Energy security concerns are building momentum for Nuclear
The IEAâs latest report on nuclear power recommends a doubling of capacity by 2050. It emphasises that, though many advanced economies are planning a decline, 32 nations have nuclear today and reactors are now under construction in 19 countries. Itâs evidence of a momentum behind nuclear power that should be further stimulated by recent spikes in oil, gas and electricity prices, says the IEA. Russia and China remain nuclear advocates, which … [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...]
A role for Coal? Low-cost, negative emissions Blue Hydrogen from âMAWGSâ Coal/Biomass co-gasification
Schalk Cloete summarises his co-authored study that explains how to make hydrogen at unbeatably low prices from coal/biomass co-gasification. Though the âblueâ hydrogen process creates CO2, the self-contained plant using a membrane-assisted water-gas shift (MAWGS) reactor means 100% is captured easily. Better still, the use of biomass means the plant achieves negative emissions. The overall efficiency of the process is a very impressive 69%. The … [Read more...]
The Nordic Code: offsetting should be used to exceed, not meet, net-zero targets
Kenneth Möllersten and Lars Zetterberg at IVL Swedish Environmental Research Institute and Hanna-Mari Ahonen at Perspectives Climate Research explain the main issues around the draft âNordic Code of Best Practice for Voluntary Compensation of GHGâ, published for consultation in June, which synthesises the most ambitious best practices for the voluntary use of carbon credits, including for offsetting. Focussing on non-state actors, the Nordic Code … [Read more...]
