The prospects for ultra-high-temperature heat pumps
An international research team has reviewed emerging solid-state and gas-cycle heat pumps capable of reaching temperatures of up to 1,600 K, assessing their challenges, applications, scalability, and technology readiness levels. The researchers say these systems could outperform conventional high-temperature heating technologies by achieving coefficients of performance above 1.
Brazil targets 107 GW of solar by 2035 under energy plan
Brazil has opened consultations on its PDE 2035 energy plan, which projects 107 GW of solar by 2035 – including 78 GW of distributed generation – with battery storage reaching 7 GW, or 2% of the power mix.
South Africans are ‘off-gridding’
Research exploring off-grid practices in South Africa has defined three forms of off-gridding, with reasons for being off-grid varying depending on income background, in turn highlighting that decentralized energy transitions can reproduce existing inequalities.
Denmark deploys 1.55 GW of solar in 2025
Denmark had a record year for solar deployment last year, with new additions led by an uptick in ground-mounted, utility-scale solar. Cumulative capacity now stands at around 6.3 GW.
Hydrostor signs California offtake deal for 4 GWh compressed air storage
Hydrostor has secured a 50 MW/400 MWh offtake agreement with California Community Power (CC Power) for its Willow Rock Energy Storage Center, providing firm capacity to six of CC Power’s community choice aggregator members.
Optimal solar module row spacing for agrivoltaics across Europe
Researchers in Sweden developed a new methodology to optimize agrivoltaic systems across Europe, showing that row pitch, system type, and panel orientation must be tailored to local climate, crops, and regulatory constraints.
Hallett battery project reaches financial close in Australia
EnergyAustralia’s 50 MW/245 MWh Stage 1 Hallett battery energy storage system (BESS), co-located with a gas-fired power station, has reached financial close and is moving into the delivery phase.
India’s blueprint for sustainable solar success
By embedding quality benchmarks into procurement and manufacturing incentives, policymakers are ensuring that India’s energy transition is durable, not disposable. The focus has moved from rapid installation to long-term reliability — a sign of sectoral maturity.
PowerBank posts $22.3 million in H2 2025 revenue amid space solar AI push
PowerBank Corp., a North American developer and operator of solar and battery energy storage projects, reported $22.3 million in revenue for the second half of 2025 and secured new credit facilities to expand its project pipeline.
France plans 2.9 GW of PV tenders despite lower 2030 target
France’s new Multiannual Energy Program sets a 48 GW solar target for 2030 and outlines 2.9 GW of tenders through 2028, with industry saying the framework restores investment visibility and supports gigafactory plans.
