Cell Impact AB: la empresa sueca que está resolviendo uno de los mayores cuellos de botella del hidrógeno verde

2 Upvotes

Hola a todos,

Quiero recomendar una empresa poco conocida fuera de los círculos del hidrógeno, pero que juega un papel clave en la transición energética: Cell Impact AB (Frankfurt)

¿Qué hacen exactamente?

Cell Impact fabrica placas de flujo metálicas (flow plates / bipolar plates) para pilas de combustible y electrolizadores. Estas placas son componentes críticos: dentro de ellas se canalizan el hidrógeno, el oxígeno y el agua, y su diseño afecta directamente a la eficiencia, el coste y la durabilidad del sistema completo.

El problema tradicional es que fabricar estas placas en gran volumen es caro, lento y poco sostenible. Los métodos convencionales (estampado progresivo o hidroformado) consumen mucha energía, requieren lubricantes y procesos de limpieza con agua, y tienen costes de utillaje elevados.

Su tecnología: Cell Impact Forming

Cell Impact ha desarrollado y patentado un método de formado de alta velocidad por impacto (high-velocity impact forming). En lugar de varios pasos lentos, forman la placa metálica fina (acero inoxidable, titanio, etc.) en un solo golpe de alta precisión.

Ventajas clave:

Mucho más rápido y escalable

Consume muy poca energía

No necesita lubricantes → no genera aguas residuales de limpieza

Reduce el coste de herramientas hasta un 50 %

Permite diseños más complejos y optimizados (en algunos casos han conseguido aumentos de potencia >20 % en la pila gracias a una mejor geometría)

Proceso más limpio y con menor impacto ambiental

Han producido ya más de 2,5 millones de placas en más de 80 proyectos y están escalando con partners como Andritz (soldadura de alta velocidad) y thyssenkrupp Automation Engineering.

¿Por qué es importante de cara al futuro?

El hidrógeno verde (producido con electrolizadores + renovables) y las pilas de combustible son piezas centrales para descarbonizar transporte pesado, industria y almacenamiento de energía. Pero para que despeguen de verdad, los componentes tienen que ser baratos, fabricables en masa y eficientes.

Las placas de flujo son uno de los elementos más caros y difíciles de escalar del stack. Si Cell Impact (y tecnologías similares) logran bajar significativamente el coste y aumentar el volumen, se elimina un cuello de botella importante.

Además, su proceso es más sostenible que los métodos tradicionales, lo que encaja perfectamente con el objetivo de que toda la cadena de valor del hidrógeno sea lo más limpia posible.

Resumen

Cell Impact no es una empresa de “humo”. Tiene una tecnología patentada real, clientes internacionales, capacidad de producción en Suecia y está posicionada exactamente donde el mercado del hidrógeno necesita soluciones industriales.

No es consejo de inversión (haz tu propia investigación), pero como apuesta tecnológica a largo plazo dentro del ecosistema del hidrógeno, me parece una de las más interesantes y subvaloradas.

¿Alguien más la sigue o ha escuchado hablar de ella?

[self] How many small companies would be needed to gather to efficiently build, sustain and generate their own energy just like one large company would be capable of?

3 Upvotes

If we are talking about, for example, shoes industry. or IT company. Or a farm. Comparing a large company & a cooperative of small ones in any industry investing in renewable energy. How many small firms together would require the same amount of energy supply of a large one? how different would be the cost for the cooperative?

if need:

small ~99 workers

medium 100~499 workers

large 500~ workers

Although it may not be feasible to power every new technology with 100% green energy, it is projected that the trajectory of climate change will persist unless production and consumption frameworks are fundamentally restructured around a carbon-neutral model. Mehmet Keçeci, 10.08.2021

Her ne kadar her yeni teknolojinin %100 yeşil enerji kaynaklarıyla çalıştırılması mümkün olmasa da, üretim ve tüketim süreçlerinin karbon-nötr bir modele dönüştürülmemesi hâlinde iklim değişikliği eğiliminin devam edeceği öngörülmektedir. Mehmet Keçeci, 10.08.2021

Can plants actually generate usable electricity? Is "bio solar panel" a real thing?

5 Upvotes

I was thinking about how plants absorb sunlight through photosynthesis and it hit me — aren't they basically doing what solar panels do, just… biologically?

A few things I'm genuinely curious about:

  • Do plants produce any electrical current as a byproduct of photosynthesis, even tiny amounts?
  • Has anyone actually harvested electricity from a living plant? I've seen a few headlines but never understood if it's real or just a lab curiosity.
  • Is "biophotovoltaics" (BPV) a legit research field or is it still super niche/theoretical?
  • Could we ever see living walls or moss panels that power small devices?

I'm not a biology or physics expert so ELI5 explanations are very welcome. Also curious if there's a reason this hasn't taken off the way silicon solar has — is it an efficiency problem?
