Welcome to the Decisive Decade for Climate Technology
We’re standing at a turning point. The 2020s are no longer about asking if we can solve the climate crisis—they’re about proving that we can do it fast enough.
Clean energy costs have plummeted, the science has sharpened, and a wave of green technology innovation is now pushing the boundaries of what’s possible.
Recent academic research shows that organizations that build green capabilities—from how they run daily operations to how they develop and launch new technologies—are the ones bringing these innovations to market faster. In particular:
- Green operations and green transactions act as the “translators” between a company’s sustainability goals and actual product innovation.
- Green technology development capability is the amplifier—making every investment in green operations deliver more impact.
Put simply, capabilities unlock technologies. And the technologies we choose to scale over the next decade will define our climate trajectory.
Here are five cutting-edge innovations we think you should know about—and how they could change our environmental future over the next 5–10 years.
1️⃣ Perovskite–Silicon Tandem Solar Panels
The short story: Stack two different solar absorbers—perovskite on top of silicon—and you capture more of the sun’s spectrum than with silicon alone.
Why it matters for the planet:
- Higher efficiency means more energy from the same space.
- Fewer panels and less material are needed per megawatt of capacity.
- Lower balance-of-system (BOS) costs and faster rooftop installations.
What’s happening now:
- In April 2025, LONGi set a 34.85% world-record cell efficiency for a two-terminal perovskite–silicon tandem, certified by NREL.
- Perovskite layers can be tuned for different wavelengths, offering efficiency gains without changing the silicon manufacturing base entirely.
Environmental win:
Tandems deliver more clean electricity per m², cutting the embedded emissions per kWh. Over a 25–30-year lifespan, this means millions more clean kilowatt-hours with the same material footprint.
What energy they need most:
- Clean electricity for manufacturing is ideal—solar made with renewable power has the lowest lifecycle emissions.
2030 outlook: Premium rooftop systems and space-constrained projects start adopting tandems.
2035 outlook: Mass-market reliability proven, production costs drop, widespread adoption in homes, businesses, and utility-scale projects.
2️⃣ All-Solid-State Batteries (ASSB) for Electric Vehicles
The short story: Replace the liquid electrolyte in EV batteries with a solid material—resulting in a lighter, safer, and potentially much faster-charging battery.
Why it matters for the planet:
- Higher energy density = longer range for the same battery size, or smaller packs for the same range (less mining, less material).
- Safer, more stable chemistry reduces fire risks.
- Faster charging can make EV adoption easier for more people.
What’s happening now:
- Toyota plans to commercialize solid-state EV packs by 2027–2028, claiming 10–80% charging in ~10 minutes.
- Panasonic’s CTO, however, warns that near-term adoption will be “niche” due to cost and manufacturing challenges.
Environmental win:
EV adoption speeds up when charging times shrink—fewer people will rely on combustion cars for long trips, slashing tailpipe emissions faster.
What energy they need most:
- Clean electricity at high power for ultra-fast charging stations.
2030 outlook: Limited high-end EV models use solid-state packs; most vehicles remain advanced Li-ion.
2035 outlook: If durability and cost hurdles fall, solid-state moves into mainstream mass-market vehicles.
3️⃣ Green Hydrogen from Solid-Oxide Electrolysis (SOEC)
The short story: SOEC splits water into hydrogen and oxygen at high temperatures (650–850°C), using both electricity and heat to improve efficiency.
Why it matters for the planet:
- Hydrogen is essential for hard-to-electrify industries like steel, fertilizers, and shipping.
- When made with renewable energy, it can replace fossil-derived hydrogen (which currently produces ~900 Mt CO₂/year).
What’s happening now:
- Demonstrations have achieved ~84% electrical efficiency (LHV).
- Bloom Energy’s tests show up to 25% more hydrogen per MW than low-temp electrolysis, when paired with industrial waste heat.
Environmental win:
Every ton of green hydrogen that replaces “grey” hydrogen prevents roughly 10 tons of CO₂ emissions.
What energy they need most:
- Clean electricity plus high-temperature heat (waste heat, nuclear, geothermal).
2030 outlook: Industrial pilot plants attached to steel mills, ammonia plants, and refineries.
2035 outlook: Larger, integrated hydrogen hubs with storage, pipelines, and industrial offtake agreements.
4️⃣ Direct Air Capture (DAC) with Mineralization
The short story: DAC machines pull CO₂ directly from the air and inject it into underground rock formations, where it reacts and turns into stable minerals.
Why it matters for the planet:
- Even if we cut emissions to zero tomorrow, we still need to remove some CO₂ to stabilize global temperatures.
- DAC provides a durable, measurable removal method—critical for hard-to-abate sectors.
What’s happening now:
- Climeworks’ “Mammoth” plant in Iceland targets 36,000 tonnes CO₂/year capacity using basalt mineralization.
- Reports show early DAC costs remain high and net removal smaller than nameplate capacity—proof it’s still an emerging tech.
Environmental win:
DAC helps “clean up” historical emissions that nature can’t absorb quickly enough, complementing aggressive emissions cuts.
What energy they need most:
- Zero-carbon electricity and sometimes heat—DAC is energy-hungry, so clean power is critical.
2030 outlook: Several DAC plants worldwide, each capturing tens of thousands of tonnes per year.
2035 outlook: Potential megaton-scale removal if powered by abundant, low-cost renewable energy.
5️⃣ Low-Carbon Cement (LC3) & CO₂-Cured Concrete
The short story:
- LC3 replaces up to 50% of high-emission clinker with limestone and calcined clay.
- CO₂ curing injects captured CO₂ into wet concrete, where it mineralizes and strengthens the material.
Why it matters for the planet:
- Cement is responsible for 7–8% of global CO₂ emissions.
- Switching to LC3 and CO₂-cured mixes can cut emissions by 30–40% immediately.
What’s happening now:
- LC3 is being tested and scaled in major construction markets.
- CarbonCure’s technology has already prevented 500,000+ tonnes of CO₂ from re-entering the atmosphere.
Environmental win:
Decarbonizing cement is one of the fastest ways to cut industrial emissions without redesigning entire supply chains.
What energy they need most:
- Low-carbon heat for calcination and clean electricity for CO₂ capture and curing.
2030 outlook: LC3 in public procurement specs; CO₂-cured concrete in large commercial projects.
2035 outlook: Cement plants integrate carbon capture and widespread use of low-carbon mixes globally.
Why Carbon and Waste Are the Core Climate Problems
- Carbon emissions trap heat and alter climate systems. Cutting them at the source (renewables, clean industry) and removing legacy CO₂ (DAC, mineralization) both matter.
- Waste in materials and energy translates directly into avoidable emissions. All five technologies reduce waste—either by using less input per output or by locking carbon into safe, permanent forms.
The Energy Connection: The Common Denominator
The thread linking all five technologies is clean electricity. Whether it’s manufacturing solar cells, charging EV batteries, producing hydrogen, running DAC machines, or curing low-carbon concrete, renewable electricity maximizes the climate benefits.
For SOEC hydrogen in particular, high-temperature heat from waste streams, nuclear, or geothermal can significantly boost efficiency.
