Amidst the perfect storm of the pandemic, war in Ukraine, and extreme weather events, Bruce Douglas at Eurelectric urges us all not to lose focus on our decarbonisation targets. Energy savings, electrification and renewables are more important than ever to help reduce dependence on fossil fuels. Douglas explains that Europe’s electricity sector remains totally committed to the drive towards clean energy, citing examples. He summarises the … [Read more...]
Modelling green Ammonia and Methanol in 2050. It will be expensive
Schalk Cloete starts by explaining that it is unrealistic to expect clean electrification to carry the main burden of energy supply. Even a fast roll out will be constrained by a range of infrastructure and cost limitations. Hence our continued dependence on fuels, with their high energy density and ease of transport. Those fuels will have to be made clean, so he summarises his co-authored papers that model the cost of green and blue ammonia and … [Read more...]
Don’t cap gas prices for consumers. It won’t reduce demand. Instead, subsidies must reward cuts in gas use
European nations are considering capping the price of gas that consumers pay, a subsidy that governments will pay for, to ensure households don’t freeze this winter. Daniel Gros at CEPS warns that this strategy will remove the incentive for consumers to cut their gas use, keeping international market prices high. Instead, governments should incentivise a reduction in gas use. Gros has modelled two strategies. The first is to pay households for … [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...]
Poland can become a major player in Offshore Wind, says PGE
PGE Polska Grupa Energetyczna’s 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 PGE’s key steps towards climate neutrality, and PGE hopes to become a leader in offshore wind in Poland. Here, Wojciech Dąbrowski, PGE’s 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 “Fit for 55” 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
It’s time for our summer break, so Energy Post thanks all of our readers and expert contributors for a tremendous first half of the year. We’ll 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...]
“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...]
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 Germany’s 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 ethanol’s 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 “wicking” of water by capillary action, improves the efficiency of … [Read more...]
