UK-Japan £18B Clean Energy Deal Signals Major Offshore Wind Expansion
The UK and Japan are finalizing an £18 billion ($24.1 billion) clean energy investment agreement expected to create jobs across offshore wind, infrastructure, and financial services sectors, according to UK Prime Minister Keir Starmer's office. The bilateral partnership represents one of the largest coordinated clean energy investments between two developed economies and underscores accelerating momentum in offshore wind development as a critical energy security solution. The deal comes as both nations face mounting pressure to decarbonize their grids while reducing dependence on fossil fuels. Expected to be formalized within days, the investment is positioned to unlock supply chain benefits and establish new manufacturing hubs in both countries, particularly for offshore wind turbine components and related infrastructure.
Solar & Wind
Pentagon reviews blocking new wind farms, sparking legal challenge — Renewable energy groups filed a lawsuit against Pentagon officials for failing to complete national security reviews of onshore wind farms on private lands, a bottleneck that threatens to delay multiple utility-scale projects and related job creation. The lawsuit alleges systematic delays in the review process are preventing qualified projects from achieving commercial operation dates critical to tax credit eligibility under the One Big Beautiful Bill Act.
Court restores 5% safe harbor rule for wind and solar — A federal judge restored the 5% safe harbor provision for wind and large-scale solar projects, allowing them to demonstrate commenced construction by the July 4, 2026 deadline and preserve eligibility for the 45Y production tax credit and 48E investment tax credit. This reversal of IRS guidance opens a new pathway for projects to secure tax incentives during the final weeks before the deadline.
US adds 6.4 GW of utility-scale solar and storage in Q1 2026 — The pipeline for new U.S. solar and battery storage projects surged in the first quarter, though land-based wind capacity remained stagnant at 28 GW of planned capacity, and offshore wind declined 33% year-over-year to 10 GW. Most of the planned offshore capacity is expected to reach commercial operation dates later in 2026 following prior delays.
EVs & Batteries
Solid-state EV batteries begin on-road testing in North America — Solid-state EV batteries are now undergoing real-world testing on North American roads for the first time, marking a major milestone toward commercialization of the technology. These batteries promise longer driving range, faster charging times, and lower manufacturing costs compared to conventional lithium-ion cells, potentially transforming the EV market within the next 2–3 years.
GM simplifies EV charging with Energy Pass and NACS adoption — General Motors is rolling out its Energy Pass charging program while transitioning all 2027 model year EVs to the NACS (North American Charging Standard) connector, eliminating the need for multiple charging apps. The move simplifies the driver experience and accelerates industry standardization around a single charging protocol.
Hydrogen & Emerging Tech
China completes largest solar-hydrogen facility with 180-ton annual capacity — China finished construction of its largest offshore solar-hydrogen-storage project in Jiangsu Province, capable of producing 180 tons of hydrogen annually while integrating solar generation and energy storage. This integrated clean energy facility demonstrates advances in coupling renewable electricity generation with hydrogen production at scale, a key pathway for heavy industry decarbonization.
Perovskite catalyst breakthrough lowers hydrogen production temperatures — Researchers at the University of Birmingham developed a perovskite-based catalyst that splits water into hydrogen at significantly lower temperatures than existing technologies, potentially making clean hydrogen fuel far cheaper and easier to produce at scale. The advancement addresses one of the primary cost barriers to hydrogen adoption in industrial applications.
Policy & Investment
EU launches €25 billion Mediterranean clean energy initiative — The European Union unveiled its T-MED initiative committing €25 billion to unlock renewable energy development across the Mediterranean region, with focus on solar, wind, hydrogen, and emerging clean technologies. The program aims to strengthen energy security across southern Europe while creating manufacturing and export opportunities for clean energy technologies.
India's climate-tech sector reaches $12.8 billion in cumulative funding — India's climate-tech ecosystem has accumulated $12.8 billion in funding across 1,583 companies, with late-stage deals increasingly dominating capital flows as the sector matures. Energy security concerns and strong government policy support are driving investment surge in renewables, e-mobility, battery storage, and industrial decarbonization.
