Descrizione del progetto
La tecnologia dei fotoni è destinata a trasformare l’anidride carbonica in combustibili
Il progetto SPOTLIGHT, finanziato dall’UE, lavorerà su un nuovo dispositivo a fotoni per la conversione di anidride carbonica e idrogeno in metano e monossido di carbonio, che costituiscono il materiale di partenza per la produzione del metanolo. I combustibili a base di metano e metanolo potrebbero essere impiegati nelle auto e in applicazioni di stoccaggio dell’energia. Il dispositivo a fotoni di SPOTLIGHT comprenderà un reattore a flusso trasparente ottimizzato per l’incapsulamento della luce nel letto del catalizzatore, ottiche solari ausiliarie per la concentrazione della luce solare e la proiezione sul reattore, nonché un diodo a emissione luminosa efficiente dal punto di vista energetico per il funzionamento continuo. Il nuovo dispositivo e il concetto di processo sono adatti a fonti di CO2 fino a 1 Mt all’anno, il che li rende complementari ai processi esistenti di cattura e utilizzo del carbonio su larga scala.
Obiettivo
SPOTLIGHT’s key objective is to develop and validate a photonic device and chemical process concept for the sunlight-powered conversion of CO2 and green H2 to the chemical fuel methane (CH4, Sabatier process), and to carbon monoxide (CO, reverse water gas shift process) as starting material for production of the chemical fuel methanol (CH3OH). Both CH4 and CH3OH are compatible with our current infrastructure, and suited for multiple applications such as car fuel, energy storage, and starting material for the production of valuable chemicals.
SPOTLIGHT’s photonic device will comprise a transparent flow reactor, optimized for light incoupling in the catalyst bed. Furthermore, it will comprise secondary solar optics to concentrate natural sunlight and project it onto the reactor, and an energy efficient LED light source to ensure continuous 24/7 operation.
SPOTLIGHT’s catalysts will be plasmonic catalysts, capable of absorbing the entire solar spectrum. The space-time-yield achieved to date with these catalysts in the Sabatier and rWGS process are > 104 times higher than for conventional semiconductor catalysts. This makes the concept technically feasible for scale up without excessive land use, and makes it economically much more attractive because of strongly reduced capital expenditures.
SPOTLIGHT’s photonic device and process concept are perfectly suited for CO2 sources up to 1 Mt p.a. which makes them complementary to existing large scale CCU processes. For the EU, we estimate that the annual CO2 reduction through use of SPOTLIGHT’s technology is maximized to 800 Mt, which is approximately 18% of the current annual total. This could generate an amount of CH4 produced in the EU which equals 14.5 EJ of energy, corresponding to 21% of the EU’s current annual energy use, and representing a value of € 393 bil. Ergo, SPOTLIGHT’s technology reduces the dependence of the EU on non-EU countries for its energy supply, and initiates a new multi-billion industry.
