Technology & Project Roadmap

An innovative waste-to-hydrogen or/and electricity, distributed modular generation reactor technology. This technology provides a mechanism to dispose of a wide range of waste streams including unrecyclable plastic by converting them to a carbon-neutral product which may be used to power fuel cell electric vehicles (FCEVs) or to generate electricity. Unlike competitive techniques for converting municipal waste to energy, the reactors do not produce toxic dioxins and furans and has a small footprint. This makes the technology suitable for deployment at enterprise or community level, producing hydrogen or electricity close to the point of consumption. Feedstocks could included mixed automotive plastic, cable insulation, shredded labels and mixed plastics, shredded beach waste, and solid recovered fuel (SRF).

The technology is carbon emission neutral when operating in power generation mode, and carbon emission negative when generating hydrogen. The small footprint and modular design of the reactor, (each capable of handling 35 tonnes of waste per day), is the equivalent to the refuse from a small town of 8,000 homes. A 35 tpd (tonnes of waste per day) reactor could potentially generate up to 2,000kg of hydrogen each day, sufficient to drive 2,000 FCEVs an average of 57 miles each. Alternatively, it could generate 3.8 Mw electricity. The reactors can be located close to where the waste material is collected, and generate electricity or hydrogen close to where it is required, thus cutting down on the costs and energy used in transportation.

The technology has numerous advantages compared with more traditional waste- to-energy techniques. Crucially, since it operates at a much higher temperature than pyrolysis, standard gasification or incineration processes, it evaporates the waste material, controlling conditions in the reactor, to break down the longer chains of hydrocarbon materials. There is no combustion of the waste to create dioxins. As the syngas is not contaminated with tar, it can potentially be used to generate hydrogen for use in fuel cells or used in a combined-cycle gas turbine engine.

Modular design, for handling larger amount of waste, scaling up is possible.

FINANCIALS:

As the process generates electricity from material that would otherwise incur a tipping fee on disposal, this improves the economics of adoption.

Process operators will receive a fee from a third party whose waste they are destroying, effectively subsidising the energy generation and making smaller modular generation economically viable.

DNA and Technology Partners will provide the material, license and support the operation, both through remote monitoring and provision of O&M systems.

GOVERNMENTS:

There are several considerations for Government agencies (local, state and federal) if presented with an application to build a waste processing plant.

Provide evidence of end markets that will purchase the end products.

Other considerations:

• Location where waste/plastic/tyres are disposed,
• gate fee,
• Cost to prepare the feedstock for the reactor,
• Stock accumulation and site requirements,
• Price to sell the end products for,
• Environmental requirements,
• Guaranteed supply.

DNA GLOBAL ENERGY PROPOSAL:

To fund, build, own and operate the plant, to deliver the above mentioned benefits for the community and government.

No capital cost to the government/community.

Fully scalable Waste to Energy plants from 40t/day up to 300t/day of waste.

The Waste to Energy plant construction can be fully funded via our Financial Partners, who would seek to reclaim their return on investment through feedstock/gate fees from government/community to process the waste and additionally through the sale of energy into the national electricity grid.
Government/community costs would entail the per-contract assessment of waste, provision of the land and relevant permissions.

Reduced cost to the government/community of waste removal through lower gate fees.
Operating company can be introduced, or can local company.

To fund and introduce a Waste-to-Energy facility, 3 key parameters must be met for a project to proceed:

1. Availability of suitable secure land, gifted or purchased at a notional cost, sited within reasonable distance of either the national grid or the end buyer of the generated electricity.
2. Funding of an adequate and long-term contracted supply of Waste, including guaranteed feedstock fees per ton from the government.
3. Adequate off take agreements for produced power in the form of a PPA (Power Purchase Agreement), and additional contracts for the supply of Hydrogen, Syngas, Heat, recycled materials and any additional export from the plant.
