Integrating offshore wind with flexibility
A new report from RenewableUK explores the potential of reforming the planning system to focus on integrating the deployment of offshore wind farms with green hydrogen and battery storage projects8. Aligning wind farms with battery or green hydrogen assets would increase flexibility and prevent wind curtailment – the planned powering down of renewable projects when there is excess generation, such as on the windiest and sunniest days, and low demand.
At present, only 3MW of operational battery storage is co-located with UK offshore wind farms. It will be essential to increase projects like this in order to utilise growing wind generation – especially in Scotland, where future offshore wind development is expected to exceed demand.
Operational offshore wind capacity increases by 15% globally
Global operational offshore wind capacity has increased by 15% compared to a year ago, reaching 80.9GW, according to RenewableUK’s newest Offshore Wind EnergyPulse Insights report9. 63% of this new capacity came from China and the Netherlands. China also currently has the largest project pipeline, with 247GW across 437 planned projects, while the UK follows in second place, with 96GW across 123 projects.
The number of projects for offshore wind farms has also increased globally in the last year, from 1,461 to 1,555, and the first offshore wind projects in Indonesia, Chile, and Malta were confirmed in 2024 – encouraging milestones for the future of wind energy!
The potential of solar carports for UK businesses
Ongoing research from RenEnergy has examined the untapped potential of solar carports – solar PV panels that sit on the roof of parking areas, allowing electricity to power businesses or the EV chargers below. This could generate 1.57GW of energy in the UK if the 546,500 suitable parking spaces the research identified have solar carports installed10.
These parking spaces range across hospitals, hotels, airports and sports centres, and RenEnergy states that there are hundreds of thousands more that could be utilised. Compared to the long planning process involved in developing large scale solar farms, RenEnergy highlights that small solar carports could receive approval in eight weeks, under permitted development with prior approval.
Solar carports and ground-mounted solar farms provide distinct benefits in the energy transition, and both serve different purposes. In the journey towards net zero, it’s important to utilise all the sustainable solutions available.
Well-managed solar farms can help biodiversity
In other solar-related news, new research from the RSPB and Cambridge University has found that ground-mounted solar farms can boost bird numbers and help wildlife, if they are managed responsibly11. Solar farms that have a large mix of habitats and were created with nature in mind have been seen to have the greatest variety of species of birds, supporting nearly three times the number of birds as nearby farmland.
Addressing previous concerns about the impact of solar farms on wildlife, this research helps confirm that the UK can increase its development of solar energy, whilst simultaneously supporting nature.
The growth in global electricity demand expected to be met by low-carbon and renewable energy generation
A new report from International Energy Agency (IEA) has predicted that global electricity demand will increase sharply until the end of 2027, due to the electrification of buildings, transportation and industry, alongside the growth of air conditioning and data centres12. The growth in electricity demand is expected to rise by 3,500 terawatt hours (TWh) across the next three years, which, according to the IEA, is the equivalent of adding Japan’s electricity usage per year.
In positive news, the report states that renewable energy is set to meet around 95% of this growth in demand in the next three years. Due to this expansion of renewable energy, alongside the lack of growth of fossil fuel-fired generation, carbon dioxide emissions from electricity generation are expected to plateau between 2025 and 2027.
