June 13 (Bloomberg) -- David Williams, Chief Executive Officer at Eco2, explains the science behind his company’s work in biomass energy using straw and tidal power. He speaks on Bloomberg Television’s “The Pulse.”

Sustainable ability -- the sustainability award.

Explain what a biomass project is and what you wpmon for.

It is food waste, biological waste, it occurs in abundance in our economy.

We turn it into energy.

Our principal elements use straw to produce energy.

You generally hear of wood chipping.

How does a wood chipping compare in terms of cost, efficiency, versus what you are doing with straw?

The wood chipping market is international.

It has a higher carbon footprints.

A lot of the objections to biomass arise because of wood.

What we do is strong.

It is a waste from food production.

It is indigenous.

We only use local material.

How about cost?

Because it is local, it is cheaper.

Because it is drier, it is more efficient.

We can produce renewable energy much more efficiently as well.

It is comparable to wood chipping.

You are being in tidal energy.

Tidal is the next big area for us.

It is currently not competitive, but we believe it will be in about three years.

You hear a lot of criticism about tidal projects that they are unrealistic and if oil prices stay below $100, it does not make sense.

What do you say to that?

Clearly it is an infant industry.

It will be expensive at the moment.

The key is to find technology that has the ability to compete.

We have removed concrete foundations, all of the expensive work.

Our device is orderable.

It can be lifted and dropped.

That is one of the keys to getting it cheap.

It is a very big scale.

What is the status of your project, the delta stream device?

It is a giant set in milford haven, off the coast of west wales.

When will it be up and running?

It is due to enter the water in about six to eight weeks time.

Everything is on track at the moment.

How big are we talking?

250 tons of steel, blades which are about eight meters wide.

Individual tubes, you can jump inside one of them.

It is a massive device.

It is far more efficient at harnessing energy.

Is it not a threat to wildlife?

That is one of the things we will be testing.

So far, no device has been a threat to wildlife.

We have strict environmental monitoring.

We will keep an eye on it.
