MWM adds hydrogen engine solutions

MWM said its TCG 3016 gas engines can now operate with a hydrogen admixture of up to 25 vol% without any technical modification.

In addition to new engines, MWM has developed a retrofit kit for the conversion of gas engines of the TCG 3016 series in the market for operation with a hydrogen admixture of up to 25 vol%.

All MWM gas engines can already be operated with a hydrogen admixture of up to 10 vol% without any technical modifications. MWM now offers the engines of the TCG 3016 series in the output range from 400 kWel to 1000 kWel for operation with hydrogen. TCG 3016 gas engines are suitable for permanent operation, base load supply, and peak operation with natural gas with a hydrogen admixture of up to 25 vol%. The hydrogen admixture of 25 vol% enables plant operators to reduce greenhouse gas emissions by 8 percent compared to natural gas-only operation.

In late 2021, the company said it will begin a staged roll-out of commercially available generator sets configured to enable operation on natural gas blended with up to 25% hydrogen for continuous, prime, and load management applications. At that time, the company said roll-out would involve the following series: TCG 3016, TCG 3020, TCG 2032 and TCG 2032B.

MWM Retrofit Kit for Existing Plants

For existing plants of the TCG 3016 series, MWM offers a retrofit kit in two editions for the conversion of gas engines for operation with a hydrogen admixture of up to 20 vol% or up to 25 vol%. By making use of hydrogen admixtures as fuel, the plant operation is possible in accordance with regulations for the reduction of greenhouse gas emissions.
