"I would say that one is that you need help from a third party to fund a product. In our case the need from the customer exists, the product is in place and we have the infrastructure to get it out on the market. We even have the legislation but there is an inertia due to the investment at the end customer. This needs to be solved via a financial plan for the customer and in that case we need a third party to fund it.

We also have a challenge that many people "know" that it's not possible to recover the energy from restaurants. Many companies have tried and failed. We have made it but need to prove it often. That is of course ok but takes time."
