Patent for License:

Environmentally attractive foundation pier & HVAC system for waterfront developments    

The pier consists of an ice core with a refrigeration system & insulation to keep the ice solid, protected by double walls typically of reinforced concrete.

Overview

The pier consists of a core of ice, maintained solid by refrigeration piping, refrigeration systems & power supply systems, armoured on its base, all sides & topside by double walls of reinforced concrete. The pier can provide an earthquake resistant foundation for a building, and also provide its heating, ventilation & air conditioning system, with close to zero carbon emissions, saving land ashore resulting in more carbon reduction benefits, provide these & other environmental benefits helping to get consents, deliver advantages in construction & while delivering these benefits, also deliver higher real estate selling prices & lower construction costs.

A pier can deliver thermal storage capability for peak electricity demand reduction for cooling load, from 30 to 1500+ megawatt hours, for a data centre, district cooling facility or cooling as a service facility, in a city center or at a waterfront, combined with structural foundations for a data centre apartment block or commercial building, in a single competitive structure.

A pier together with its buildings can be made offsite & floated into place by tugs for waterfront locations, or made in situ for city center or industrial park locations.

Primary Application of the Technology

The primary application is as a combined foundation pier plus heating ventilation & air conditioning supply system for waterfront real estate.

The Problem Solved by the Technology

The problem solved is the problem of using ice as a structural material at locations where temperatures are above its melting point of 32 degrees Fahrenheit. Ice has the strength of lean mix concrete but costs a small fraction of its cost. To use ice as a structural material at above 32 degrees Fahrenheit necessitates refrigeration & insulation of the ice and protection from the environment. The patent pier does this in a way that results in the pier being able to deliver certifiable & insurable structural use of the ice. The patent pier also has the capability to use the heat from its refrigeration system in heating applications in buildings on the pier & to use a part of the same pier for the cooling needed for air conditioning, in a single certifiable & competitive structure.

Competitive Advantage

The pier provides several major tangible benefits for a single cost. The first is land value at high priced waterfronts, the value of the earthquake resistant structural foundation provided. The second is the heating ventilation & air conditioning supply system for buildings on the pier built into the capital cost of the pier & its renewable electricity supply system, resulting in near zero carbon emission development. These & a number of other environmental & public realm benefits are projected to help get consents to build at waterfronts & in the sea.

The competition for the approach in the development land market is high rise development, land reclamation or a conventional pier at waterfronts. The patent pier is competitive with high rise because it enables a developer to turn over his equity faster & its earthquake resistance costs less. It has significant environmental & public realm advantages over low and medium rise development, land reclamation & conventional piers. In addition its capital & operating cost is lower than a conventional pier of the same structural capability. When renewable electricity is used as the power source for the pier systems as is planned, it can increase the amount of renewable electricity usable, particularly off peak electricity from intermittent sources such as wind turbines. The result can be a close to zero carbon emission development initially and in time an overall carbon sink.

The reason the technology is superior in providing large scale ice thermal storage for the large scale peak load shaving market is that the competition in this market is ice thermal storage tanks and they need a building to house them which adds to their cost.

The interplay of these advantages determines the locations & market sectors in which the technology is most profitable.

The seller may consider selling these patents individually.

Frequently Asked Questions

What are the technical risks in using the new technology?
The technology is a unique integration of mature technologies & there are no technical risks in the individual technical elements. There is a rationale for a pre-commercial scale demonstration of a mini-pier. As this could also function as a showcase for at least one office & apartment unit, this is recommended by & will be supported by the vendor.

Is the power to keep the ice solid not prohibitively expensive?
No, this power requirement is controlled to whatever level is desired by the insulation of the ice core using double walls with an insulating air gap. Any heat that leaks in is captured by the structural refrigeration system & can be used to heat the building on top, or in some other heating applications such as fish farming or aquaculture.

What happens if the renewable power source or the grid power source fails?
The standby diesel power system and the UPS system will ensure structural integrity.

If all power sources did fail, how long would it be before the ice core would reach 32 degrees Fahrenheit?
Recommended design temperature of the ice is 26 degrees Fahrenheit. If all power sources did fail, after about 60 days the average core temperature would reach 32 degrees Fahrenheit & some ice would start to melt.

If for whatever reason the power did fail for such a long period that all the structural ice melted what would happen?
If the main power and the standby diesel power and the UPS system failed & all failures lasted for over 200 days, the core in a standard sized pier would start to melt after about 60 days & could melt completely after about 200 days. However if that is foreseen as a possibility the pier topside and its building load can be designed to be able to float in the melt water. This feature means that such a fixed pier could be designed to cope with rising sea levels, by deliberately doing this, raising the floating topside level supporting buildings & refreezing the pier core. This could be done for fixed piers if sea levels actually rise as forecast. Piers can also be designed to float as ice is less dense than water & such floating piers will automatically rise & fall with tidal rise & fall & automatically rise as sea levels rise.

How does the pier cope with tidal rise & fall?
For such piers access is by a landing stage identical to those used by car ferries for getting cars & HGVs from shore to ship & back to shore.
