The time and place for geoengineering projects

 Geoengineering efforts offer a science fiction-style get-out option as the effort to avert catastrophic climate change comes down to the wire. Interest and investment in such projects shift resources away from the mainstream energy transition but some suggest the value of the research lies in a worst-case scenario

How to sink the cost of floating offshore wind

 Floating platforms could open up swathes of the ocean with water depths beyond 60 metres to the offshore wind sector. To tap into those areas, though, floating offshore wind first needs to become less expensive. A European research project is looking to secure some of those price gains to make the technology finally competitive

Wind turbines in a race to become even cleaner

 The growth of wind power capacity is accelerating globally, with 2020 a record year for new installations. But with the expansion comes a growing mass of production waste, emissions from manufacturing and transport, and discarded components from retired machines. The industry’s turbine makers are facing up to the problem but proposed solutions remain commercially immature

Italy’s dreams of a green hydrogen future rest on its renewables plan

 Italy is putting many eggs in the hydrogen basket to decarbonise its heavy industry, including its prized steel sector. Authorities dream of converted hydrogen steel plants and “hydrogen valleys” dotted across the country. But while attention is focussed on whether hydrogen can solve Italy’s problems, other key ingredients to make the hydrogen green are being ignored

Concentrated solar power faces existential threat

 It cannot easily compete with wind and solar PV for daytime electricity generation but in countries with high levels of direct solar irradiation concentrated solar power could play a vital role in decarbonising energy systems thanks to its ability to act as a thermal battery for overnight production. But few markets are rewarding dispatchable overnight renewable energy, putting the future of the industry at risk

Battery powered transportation is not yet as green as it should be

 While electric vehicles have proved to be better for the environment than those running on fossil fuel, their production leaves a bigger carbon footprint than making an internal combustion engine equivalent. How batteries for EVs are produced and for how long they last are decisive for making the shift to electric transport as carbon light as possible

Flexibility experiments work to cut the system costs of solar and wind

 Network operators tasked with managing the steadily bigger swings in demand and supply that accompany greater uptake of solar and wind energy have had to choose between constraining clean generation, which adds to operating cost, or increasing grid capacity requiring capital expenditure. A less costly way is to buy system flexibility in a competitive but carefully coordinated process. Trials in areas of Britain challenged by grid constraints are producing encouraging results

Why hydrogen trains are tracking hot

 Hydrogen suffers from an abundance of hype, particularly about what it can be used for in the energy transition. Wild claims for the application of hydrogen, with little basis in current science and commercial reality, have worked to obscure the realistic opportunities for putting truly clean hydrogen to work here and now.

Decarbonised heat within a decade in Denmark

 Denmark has led the way on decarbonisation of heating, with a rapid transition away from fossil fuels aided by its large scale adoption of heating networks over the past 40 years. Instead of exchanging individual heating appliances in every home and commercial building, the Danes are centrally converting their heat networks to renewable energy, saving citizens a pile of money in the process
