Iberdrola has agreed to supply ammonia trader Trammo with 100,000 tonnes of green ammonia a year from 2026. Other renewables developers should look at the role green ammonia can play in their power-to-X plans.

The US will lose its position as the leading deployer of energy storage to Asia by the end of the decade, with China and India being the driving forces

China has dominated battery manufacturing, but ethical concerns about the country's lithium mines mean pressure is mounting on energy storage companies and electric vehicle manufacturers to source their batteries elsewhere

The US Department of Energy has shared its strategy for growing the low-carbon hydrogen sector, including a focus on high-priority off-takers, cost-cutting and regional hubs. Its willingness to engage with hydrogen's biggest challenges should hope to green hydrogen investors.

With lithium-ion batteries raising ESG-related concerns, investors are increasingly seeing value in long-duration storage

The US Inflation Reduction Act 'opened the door' for tax equity investment in standalone storage, but exorbitant costs and a shortage of providers make it an unrealistic option for smaller developers

Republicans in Texas are pushing for wide-ranging legislative changes that could undermine the investment credentials of wind farms and end the US state's long wind boom. The impacts for the industry could be far-reaching.
