MG Becomes First to Mass-Produce Semi-Solid-State EV Battery With New 4X SUV
SAIC's MG brand is poised to set a new industry benchmark by becoming the first automaker to achieve mass production of semi-solid-state EV batteries, embedded in the forthcoming MG 4X electric SUV. The vehicle goes on sale in China next week, with European availability planned before the end of 2026. MG's proprietary SolidCore Battery technology has been engineered to accommodate regional road conditions, climate variations, and regulatory requirements across different markets.
The semi-solid-state chemistry promises longer driving ranges, faster charging speeds, enhanced safety, and improved cold-weather performance compared with conventional lithium-ion packs — without the manufacturing complexity that has delayed fully solid-state rivals. While Greater Bay Technology (backed by GAC Group) has also announced ambitions for a mass-producible all-solid-state cell this year, MG's claim to be first-to-market with a semi-solid-state vehicle puts competitive pressure on every major EV manufacturer.
The European rollout will be tailored to local regulations and climate demands, suggesting SAIC views this technology as a global platform rather than a China-only play. Industry observers will watch closely whether the SolidCore Battery translates real-world range improvements that match the company's claims — and whether the timing advantage cements MG's position as a battery-tech leader heading into the second half of 2026.
Solar & Wind
UK Wind and Solar Save Consumers £1.7 Billion Carbon Brief's 8 May 2026 weekly briefing highlights new analysis showing that wind and solar generation saved UK electricity consumers approximately £1.7 billion — an figure that underscores renewables' growing role in suppressing wholesale power prices. The same briefing notes the EU is considering exempting fossil-fuel firms from methane rules, a potential policy setback that has drawn criticism from climate advocates.
India's Rays Power Infra Commissions 1.1 GW of Solar in a Single Year Rays Power Infra has commissioned 1.1 GW of solar capacity within a single financial year, marking its strongest-ever year of project execution. The milestone underscores the rapid pace of utility-scale solar deployment across India as the country races toward its renewable energy targets.
UPEX 2026 Clean Energy Expo Opens in Lucknow The Uttar Pradesh Energy Expo 2026 (UPEX 2026), now underway through May 9 at Indira Gandhi Pratishthan in Lucknow, has convened more than 10,000 industry stakeholders to drive solar, storage, EV, and grid transformation across India's most populous state. The second edition of the event signals growing momentum for Uttar Pradesh's clean energy transition.
EVs & Batteries
MG 4X: World's First Mass-Production Semi-Solid-State Battery Vehicle (See Top Story above)
Used EV Battery Health Remains Robust Through Five Years New data from Recurrent, published this week by InsideEVs, shows the average electric vehicle retains 97% of its original range after three years and 95% after five years. The findings challenge common consumer fears about long-term battery degradation and provide fresh support for the used-EV market heading into 2026's peak sales season.
Fervo Energy's $1.3 Billion Geothermal IPO Targets AI Power Demand Geothermal developer Fervo Energy is targeting a $1.3 billion IPO, positioning next-generation geothermal power as a reliable 24/7 clean electricity source for data centers and AI infrastructure. The filing comes as surging AI compute demand creates new urgency for dispatchable, carbon-free power that solar and wind alone cannot provide.
Hydrogen & Emerging Tech
Researchers Turn Plastic Waste Into Clean Hydrogen Using Old Car Battery Acid Scientists have demonstrated a circular upcycling system that converts hard-to-recycle plastic waste into clean hydrogen, using sulfuric acid recovered from end-of-life car batteries as a catalyst alongside solar power. The process simultaneously addresses three problematic waste streams — plastics, spent batteries, and carbon emissions — and was detailed in a Live Science report published within the past 72 hours.
EU Eyes Fossil-Fuel Methane Exemptions — A Setback for Hydrogen's Competitors The European Commission is reportedly weighing exemptions for fossil-fuel companies from new methane emissions regulations, according to Carbon Brief's May 8 briefing. Methane rules are considered critical for making green hydrogen cost-competitive versus fossil-derived alternatives; any weakening of those rules could distort the competitive landscape for the emerging green hydrogen sector.
Policy & Investment
Apple Deepens India Clean Energy Push With $10.6 Million Investment Apple has expanded its renewable energy footprint in India with a $10.6 million investment, accelerating its push toward a carbon-neutral supply chain by 2030. The move aligns with India's growing role as a manufacturing hub for Apple products and underscores how major tech companies are tying supplier relationships to clean energy commitments.
Fervo Energy Files for $1.3 Billion IPO Fervo Energy's planned $1.3 billion public offering (reported within the past 48 hours) represents one of the largest IPOs in the geothermal sector's history, signaling that investors are ready to back firm, dispatchable clean power at scale. The company has positioned itself at the intersection of the AI data-center boom and the energy transition.
Carbon Brief's Weekly Policy Roundup: EU Methane Backsliding, UK Renewables Savings Carbon Brief's May 8, 2026 briefing — published within the past 24 hours — flags two significant policy developments: the European Commission's consideration of fossil-fuel exemptions from methane rules, and fresh analysis showing UK wind and solar have delivered £1.7 billion in consumer savings. The briefing also notes emerging concerns about Amazon-related "tipping point" environmental risks.

What to Watch This Week
- MG 4X on sale in China: Monitor real-world range and charging speed reports from early adopters to validate the SolidCore semi-solid-state battery's performance claims — and watch for competitive responses from BYD, CATL, and European automakers.
- Fervo Energy IPO developments: Keep an eye on the $1.3 billion IPO filing timeline and investor reception, as it could set a precedent for geothermal and other firm-power clean-energy listings in 2026.
- EU methane rule negotiations: Brussels is weighing fossil-fuel exemptions from methane regulations; any formal proposal this week would have significant downstream effects on green hydrogen economics and European climate credibility ahead of COP31 preparations.
