They [the European Commission] are looking at this stuff backwards. I still think they are convinced the short-term market model could work even though they are also starting to realise that you need something parallel, with long term price signals that give investors confidence to invest in infrastructure and allow them to see a decent market return.

Francesco Venturini

- Global head of renewables for Italian utility Enel

Despite tremendous cost decline of wind and solar technologies, electricity prices will probably remain too low to attract the level of investment needed.

The greatest barrier to overcome is the integration of variable renewables into electricity systems. This will require developing power system flexibility and also a friendly deployment of variable renewables.

The greening of steel

Green hydrogen is set to have a significant role in decarbonising the steel industry. Policies are essential to help close the cost gap with production methods relying on fossil fuels and ensure that green steel plants come online in the next few years. Emerging Power-to-X technologies, in particular iron ore electrolysis, could also play a part

Salt caverns for hydrogen storage


The UK should help kickstart the development of salt-cavern hydrogen storage to meet its goal of net zero by 2050, says the Royal Society. Work on constructing the caverns should begin immediately, the new report states, where parts of the UK have the right geology for the storage projects. Large-scale electricity storage is needed to smooth out variations in wind and solar, particularly long-term variations in wind. Storing most of the surplus as hydrogen, in salt caverns, would be the cheapest way of doing this, says the report.

US needs to exploit Grid-Enhancing Technologies


The US needs to triple transmission investment and use Grid-Enhancing Technologies (GETs) to support this goal, concludes a white paper by Brattle Group and the Watt Coalition. There are more than 10,000 projects adding up to over two terawatts of new capacity awaiting grid connection. When compared to major new transmission investments, GETs can be implemented much faster and often for a small fraction of the cost. GETs enhance transmission investments, acting more as a tool to augment, akin to a GPS or tire air pressure sensor making driving easier—not by themselves replacing the car.

Offshore wind growth accelerates


Offshore wind capacity is expected to grow by 18.4 GW in 2023, a record, with China accounting for over half of this total. By 2030, the annual total will reach 45.7 GW, mainly due to the mature markets of China, the UK, Germany and the Netherlands, but emerging markets such as the US, Taiwan, France, South Korea, Poland and Japan will also make significant contributions. From 2031 to 2035, the report says that installations will average 45.6 GW per year, peaking at 48.2 GW in 2035.
