Competition with fossil sources is very hard!
Production of high‐added value chemicals along with biofuels may render the biorefinery approach competitive

Concept and project objective(s)
•The key objective ot the project will be to provide evidence that fine chemical products can be effectively produced in a cost-competititve way comparable to their synthesis from petroleum derivatives. In any case, production rates of 100 g product/h
in pilot reactors will need to be attained.
•A targeted efficiency exceeding 6% for this conversion process
is set, calculated, per unit surface area exposed, as the ratio between the higher heating value of the produced methanol and the overall incoming solar power. Model calculations, presented in the impact section, show that this con-cept has the potential to exceed 10% conversion efficiencies
•The perspected system durability
will exceed 10.000 h
lifetime. A 10x10 cm2
prototype will be manufac-tured and tested by the end of the project
to prove the achievement of the above targets and pave the way to subse-quent exploitation of the technology. The test duration
will be at least 1000 h
in the last six months of the project.
•To disclose wide potential application opportunities, the above targets must be reached without using expensive noble metals or materials
and via assembling techniques
amenable for mass production.

- Exploit semiconductors
- Keep them away from water
- Operate at high pressures (if CO+H2
is the target)
- Exploit sun concentration
- Exploit heat from the sun
